DISC DIRECTION. Only sand on the downward- moving left side of the sanding disc. Sanding on the upward-moving right side of the sanding disc forces the operator to rely only on hands (rather than the table) for support, which increases the risk of workpiece "kick-out" and impact/abrasion injuries.

AVOIDING ENTANGLEMENT. Becoming entan- gled in the moving parts of this machine can cause pinching and crushing injuries. To avoid these hazards, DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place and secure.

HAND PLACEMENT. Rotating sandpaper can remove a large amount of flesh in a few seconds. Always keep hands away from the sandpaper during operation. Never touch moving sandpaper on purpose.

MINIMUM STOCK DIMENSION. Small workpieces can be aggressively pulled from your hands and present injury hazards. Always use a jig or other holding device when sanding small workpieces, and keep your hands and fingers at least 2" away from the sanding surface.

WORKPIECE SUPPORT. Workpiece kickback can occur with violent force if the workpiece is not properly supported during operation. Always sand with the workpiece firmly against the table or another support device.

SANDING DUST. Sanding creates large amounts of dust and flying chips that can lead to eye injury or respiratory illness. Reduce the risk of these hazards by always wearing approved eye and respiratory protection when using the sander.

WORKPIECE INSPECTION. Nails, staples, knots, or other imperfections in the workpiece can be dislodged and thrown from the sander at a high rate of speed into the operator or bystanders, or cause damage to sandpaper or sander. Never attempt to sand stock that has embedded foreign objects or questionable imperfections.

FEEDING WORKPIECE. Forcefully jamming the workpiece into the sanding surface could cause the workpiece to be aggressively grabbed and pull your hands into the sanding surface. Always firmly grasp the workpiece in both hands and ease it into the sandpaper using light pressure.

SANDPAPER CONDITION. Sandpaper that is worn or damaged not only produces poor sand- ing results, but could fly apart, aggressively grab the workpiece, and throw debris at the operator. Always inspect the sandpaper before operation and replace it if worn or damaged.

IN-RUNNING NIP POINTS. The gap between the moving sandpaper and the fixed table/support creates a pinch point for fingers or workpieces; the larger this gap is, the greater the risk of fingers or workpieces getting caught in it. Minimize this risk by adjusting the table no more than 1???16" away from the sandpaper.

WORKPIECE INTEGRITY. Only sand solid workpieces that can withstand the forces required for power sanding. Make sure the shape of the workpiece can be properly supported on the table; avoid sanding workpieces without flat bot- tom surfaces unless some type of jig is used to maintain support and control when the sanding force is applied.

Availability

Before installing the machine, consider the avail- ability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocu- tion, fire, or equipment damage, installation work and electrical wiring must be done by a qualified electrician in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power supply.

Full-Load Current Rating

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result??? especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid over- loading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

Model G1183/G1276 (Mfg. Since 3/10)

Circuit Information

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power sup- ply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

For your own safety and protection of property, consult a qualified electrician if you are unsure about wiring practices or electrical codes in your area.

Note: The circuit requirements listed in this man- ual apply to a dedicated circuit???where only one machine will be running at a time. If this machine will be connected to a shared circuit where mul- tiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation.

Circuit Requirements for 110V

This machine is prewired to operate on a 110V power supply circuit that has a verified ground and meets the following requirements:

Circuit Requirements for 220V

This machine can be converted to operate on a

220V power supply (refer to Voltage Conversion instructions). This power supply must have a veri- fied ground and meet the following requirements:

Grounding Requirements

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

For 110V operation: This machine is equipped with a power cord that has an equipment-ground- ing wire and a grounding plug (see following fig- ure). The plug must only be inserted into a match- ing receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.

SHOCK HAZARD!

Two-prong outlets do not meet the grounding requirements for this machine. Do not modify or use an adapter on the plug provided???if it will not fit the outlet, have a qualified electrician install the proper outlet with a verified ground.

-12-

For 220V operation: The plug specified under

???Circuit Requirements for 220V??? on the previous page has a grounding prong that must be attached to the equipment-grounding wire on the included power cord. The plug must only be inserted into a matching receptacle (see following figure) that is properly installed and grounded in accordance with all local codes and ordinances.

Figure 7. Typical 6-15 plug and receptacle.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is nec- essary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service per- sonnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, discon- nect it from power, and immediately replace it with a new one.

Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual.

Model G1183/G1276 (Mfg. Since 3/10)

Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following require- ments:

Model G1183/G1276 (Mfg. Since 3/10)

Voltage Conversion

The voltage conversion MUST be performed by an electrician or qualified service personnel. Make sure the power supply circuit for the new voltage meets the specified circuit requirement on

Page 11.

To convert the machine to 220V:

1.DISCONNECT MACHINE FROM POWER!

2.Replace the 5-15 plug on the power cord with a 6-15 plug.

3.Re-wire the motor as illustrated in the wiring diagram on Page 39.

Cleanup

The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean.

Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.

There are many ways to remove this rust preven- tative, but the following steps work well in a wide variety of situations. Always follow the manufac- turer???s instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

???Disposable Rags

???Cleaner/degreaser (WD???40 works well)

???Safety glasses & disposable gloves

???Plastic paint scraper (optional)

Basic steps for removing rust preventative:

1.Put on safety glasses.

2.Coat the rust preventative with a liberal amount of cleaner/degreaser, then let it soak for 5???10 minutes.

3.Wipe off the surfaces. If your cleaner/degreas- er is effective, the rust preventative will wipe off easily. If you have a plastic paint scraper, scrape off as much as you can first, then wipe off the rest with the rag.

4.Repeat Steps 2???3 as necessary until clean, then coat all unpainted surfaces with a quality metal protectant to prevent rust.

-16-

Gasoline or products with low flash points can explode or cause fire if used to clean machin- ery. Avoid cleaning with these products.

Many cleaning solvents are toxic if concentrat- ed amounts are inhaled. Only work in a well-venti- lated area.

NOTICE

Avoid chlorine-based solvents, such as acetone or brake parts cleaner, that may damage painted surfaces. Test all cleaners in an inconspicuous area before using to make sure they will not damage paint.

Model G1183/G1276 (Mfg. Since 3/10)

Weight Load

Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest work- piece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the main- tenance and service described in this manual.

See below for required space allocation.

Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.

Physical Environment

The physical environment where your machine is operated is important for safe operation and the longevity of its components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemi- cals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41?????104??F; the relative humidity range exceeds 20???95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device.

Lighting

Lighting around the machine must be adequate enough that operations can be performed safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated.

The base of this machine has holes that accept 5???8" bolts for mounting the machine to a workbench. We strongly recommend that you mount your machine to a workbench to prevent it from moving during operation. An unexpected movement could result in an injury or property damage.

The strongest mounting option is a "Through Mount" where holes are drilled all the way through the workbench, and hex bolts, washers, and hex nuts are used to secure the drill press to the work- bench.

Figure 10. Example of a through mount setup.

Another option for mounting is a "Direct Mount" where the machine is simply secured to the work- bench with a lag screw and flat washer.

Table Gap

Adjustment

To reduce the risk of in-running nip (pinch) points, yet avoid the risk of the sandpaper contacting the tables, the tables should be adjusted away from the sandpaper no more than 1???16".

Note: The procedure for the table gap adjustment is similar for both tables.

To adjust the table-to-sandpaper gap:

1.DISCONNECT SANDER FROM POWER!

2.First, check the existing adjustment by slid- ing the miter gauge into the table T-slot, then positioning a 90?? square flat against the miter face and up against the sanding surface, as shown in Figure 20.

Figure 20. Positioning the miter gauge and square for aligning the table.

???If the square is flat against the miter face and the sanding surface, and the table is no more than 1???16" away from the sandpaper for both tables, no adjustments are need- ed. Fully tighten the hex bolts underneath the table. Continue to the Checking Belt Tracking procedure.

???If the square is not flat against the sanding surface as it remains flat against the miter face, or the table is not at least 1???16" away from the sanding surface, continue with the next step.

Model G1183/G1276 (Mfg. Since 3/10)

3.Loosen the hex bolts underneath the table that secure it to the trunnion(s).

Note: The sanding belt table has three hex bolts (see Figure 21), and the sanding disc table has two hex bolts on both sides of the table (see Figure 22).

Hex Bolts

4.Adjust the table so that when the square is flat against the miter face and the sanding surface at the same time, and that the table is no more than 1???16" away from the sandpaper, then re-tighten the hex bolts.

5. Repeat Step 2 to make sure the table is properly positioned. If necessary, repeat Steps 3???4 until it is.

Model G1183/G1276 (Mfg. Since 3/10)

Checking Belt

Tracking

Proper belt tracking depends on two conditions: 1) The platen height, and 2) the upper roller paral- lelism.

The upper belt roller is designed with a slight crown in the middle, and the belt platen should be even with the highest point of this crown to ensure proper belt tracking.

Additionally, the upper roller should be parallel to the lower roller so that the sanding belt rides evenly in the middle of the rollers.

To check the belt tracking:

1.DISCONNECT SANDER FROM POWER!

2.Put on heavy leather gloves to protect your hands from the abrasive sandpaper

3.Rotate the sandpaper belt down toward the table several times by hand???NOT by pow- er???as fast as possible (see Figure 23).

???If the belt stays centered on the rollers, continue to the Dust Collection procedure on Page 22.

???If the belt begins moving to one side or the other, perform the Tracking Roller &

Platen Adjustment on Page 35 to make sure the belt tracks properly.

Figure 23. Rotating the sanding belt to check belt tracking.

Dust Collection

DO NOT operate the Model G1183/G1276 without an adequate dust collection system. This sander creates substantial amounts of wood dust while operating. Failure to use a dust collection system can result in short and long-term respiratory illness.

Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector,

(2) hose type and length between the dust col- lector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to cal- culate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

-22-

To connect the sander to the dust collection system:

1.Fit the dust hoses over both dust ports, as shown in Figure 24, and secure them in place with hose clamps.

2.Tug the hoses to make sure they do not come off. Note: A tight fit is necessary for proper performance.

Figure 24. Dust hoses attached.

6.Makes sure the sanding belt is tracking prop- erly.

7.Feeds the workpiece slowly into the sand- paper while maintaining firm pressure on the workpiece against the table or miter gauge. Keeps hands and fingers away from the mov- ing sandpaper.

8.Stops the machine.

Table Tilt

Angle sanding is performed with the table tilted away from 0?? (perpendicular to the sanding sur- face). Compound angles are sanded using a com- bination of table tilt and miter gauge angle.

Both tables have an adjustable positive stop that is used to quickly return the table to 0??. The belt table has an additional stop at -45?? and uses a flip stop to engage the stops. The disc table has an additional stop at -40?? underneath the table (see

Figures 27???29).

No list of safety guidelines can be com- plete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equip- ment, or poor work results.

Sandpaper Selection

Sanding a workpiece smooth requires using pro- gressively smaller grit sandpaper until the desired finish is attained.

The abrasiveness of sandpaper is designated in grit size???the larger the number, the finer the abrasive and the smaller the scratches. Thus, 100 grit is finer than 60 grit.

Typically, sanding operations start with a coarse grit and progressively work through the finer (larger number) grits until the desired finish is achieved. Avoid skipping a grit to achieve the best results.

Choosing the correct grits involve many factors, such as the workpiece condition, type/hardness, and the desired finish.

There are many types of sanding belts and discs to choose from. We recommend Aluminum Oxide for general workshop environments. Below is a chart that groups abrasives into different classes and shows which grits fall into each class.

To ensure good sanding results, never skip more than 50 grit with each sandpaper change.

Sanding Belt

Replacement

The Model G1183/G1276 ships with a pre-installed 80-grit, 6" x 48" sanding belt.

1.DISCONNECT SANDER FROM POWER!

2.Loosen the four Phillips head screws that secure the left cover of the sanding belt hous- ing, then remove the cover.

3.Pull the spring-loaded quick-release tension lever forward to lower the top roller, then remove the sanding belt.

Note: Typically, sanding belts have a direc- tion arrow printed on the inside. Match this arrow with the direction arrow label on top of the sanding belt housing (see Figure 30). This will ensure that belt seams are correctly oriented for longer belt life.

Model G1183/G1276 (Mfg. Since 3/10)

The Model G1183/G1276 sander ships with a pre- installed 80-grit, 12" diameter adhesive-backed sanding disc.

The sanding disc sticks to the surface of the cast iron disc platen, using the pressure-sensitive adhesive (PSA) backing. The sandpaper can be replaced without removing the table or dust port.

To replace the disc sandpaper:

1.DISCONNECT SANDER FROM POWER!

2.Peel off the old sandpaper, clean the disc surface with mineral spirits, then wipe it dry.

3.Peel back the protective layer on one-half of the sandpaper disc and fold it against the remaining half.

4.Slip the half with the protective layer between the disc and the table edge (see Figure 31 for an example).

Figure 31. Example photo of installing the sandpaper disc.

5.Position the exposed adhesive on the upper half of the aluminum disc that extends above the table. Once it is positioned evenly across the disc, press the adhesive onto the sur- face.

6.Rotate the disc so the lower half is above the table. Peel off the other half of the protective paper, then press the remaining sandpaper against the disc so adhesion is complete.

Model G1183/G1276 (Mfg. Since 3/10)

Only sand on the downward-moving left side of the sanding disc. Sanding on the upward- moving right side of the sanding disc forces the operator to rely only on hands (rather than the table) for support, which increases the risk of workpiece "kick-out" and impact/ abrasion injuries.

Refer to Figures 32???35 for examples of sand- ing operations that are possible with the sanding disc.

Figure 32. Example photo of 90?? disc sanding.

Belt Sanding

The sanding belt removes material faster than the sanding disc, and can be secured at any angle from horizontal to completely vertical with the use of the pivot cap screw shown in Figure 36.

Pivot

Cap Screw

Figure 36. Positioning the sanding belt assembly.

If the sanding belt or table unexpectedly moves when sanding, your hands could slip and contact the moving sandpaper, result- ing in abrasion injuries. Always make sure the table lock lever and the sanding belt pivot cap screw are tight before operation.

Always sand with the workpiece supported by the table. Relying only hands to sup- port the workpiece increases the risk of workpiece "kick-out" and impact/abrasion injuries.

Refer to Figures 37???40 for examples of sanding operations that are possible with the belt sanding assembly.

Figure 39. Example of vertical miter sanding.

Figure 40. Examples of vertical face and edge sanding.

Sanding workpieces with high-resin content or with applied finishes can quickly con- taminate the sandpaper beyond the point where it can be properly cleaned. This will produce poor sanding results. In this case, use a different workpiece, remove the applied finishes, or frequently clean/replace the sandpaper strip.

Cleaning &

Protecting Machine

Cleaning the Model G1183/G1276 is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it.

Protect the unpainted cast iron surfaces on the table by wiping the table clean after every use??? this ensures moisture from wood dust does not remain on bare metal surfaces. Then apply a non- staining rust preventative that does not contain silicone or oil.

Cleaning Sandpaper

When the sandpaper surface becomes clogged with resin or gummy sawdust, the efficiency of the sanding operation is significantly reduced and can leave glazed or gouge marks in the workpiece.

Regularly clean the belt and disc sandpaper by using crepe-rubber cleaners (see Accessories on Page 31 for options from Grizzly).

Model G1183/G1276 (Mfg. Since 3/10)

Tracking Roller &

Platen Adjustment

To ensure proper belt tracking, the belt platen must be even with the upper roller crown and the upper and lower rollers must be parallel.

To adjust the roller and platen:

1.DISCONNECT SANDER FROM POWER!

1.Remove the side cover and table from the belt assembly.

2.Pull the quick-release tension lever down, then remove the sanding belt, as shown in

Figure 47.

3.If the sanding belt assembly is not already horizontal, loosen the cap screw shown in Figure 48 and lower the assembly to the horizontal position.

Loosen this pivot cap screw.

Figure 48. Location of the cap screw that secures the rotation of the belt assembly.

Model G1183/G1276 (Mfg. Since 3/10)

4.Place the straightedge over the platen and upper roller aligned with the middle of the roller (the crown at the highest point), as shown in Figure 49.

Figure 49. Comparing the platen height with the upper roller crown.

???If the platen is not even with or is higher than the upper roller crown, loosen the platen cap screw shown in Figure 49, adjust the platen even with the middle of the top roller, then re-tighten the cap screw to secure the platen in place.

5.Replace the sanding belt, put on gloves to protect your hands, then rotate it several times by hand???NOT by power.

???If the sanding belt tracks steadily in the middle of the rollers without moving to one side or the other, no other adjustments are necessary. Continue to Step 11.

???If the sanding belt does track to one side or the other, continue with next step.

-35-

6.Fully loosen the locking thumb wheels on both of the roller adjustment screws shown in

Figure 50.

Adjustment Screws

& Locking Thumb Wheels

Figure 50. Upper roller adjustment screws and locking thumb wheels.

7.Back out the adjustment screws so that they are not against the belt housing.

Note: The next step is matter of trial-and- error until you attain proper belt tracking. The adjustment screws control the tilt of the upper roller to make it parallel with the lower roller, which affects the belt tracking.

-36-

8.Make small changes to the adjustment knobs as you continue to rotate the sanding belt by hand.

9.When the sanding belt continues to track in one position on the rollers, make sure both adjustment screws are making contact with the belt housing, then re-tighten the locking thumb screws.

10.Repeat Step 4 to make sure the platen is still even with the crown of the upper roller.

11.Replace the side cover and table to the belt assembly before connecting the sander to power.

12.When first connecting the sander to power after this, turn it ON and watch the belt track- ing closely.

???If the sanding belt begins to track to one side or the other, immediately turn the machine OFF and disconnect it from power. Then, repeat this procedure until the belt tracks properly.
