SECTION 2: POWER SUPPLY

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 electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel 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.

Full-Load Current Rating at 220V..... 6.6 Amps

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.

-10-

Circuit Requirements for 220V

This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements:

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 an 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.

Model G0756 (Mfg. Since 2/13)

Grounding Instructions

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.

The power cord and plug specified under ???Circuit

Requirements for 220V??? on the previous page has an equipment-grounding wire and a ground- ing prong. The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances (see figure below).

Figure 2. NEMA 15-15 plug and outlet.

No adapter should be used with the required plug. If the plug does not fit the available receptacle, or the machine must be reconnected for use on a different type of circuit, the reconnection must be made by a qualified electrician and comply with all local codes and ordinances.

Model G0756 (Mfg. Since 2/13)

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.

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.

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:

NOTICE

If you cannot find an item on this list, care- fully check around/inside the machine and packaging materials. Often, these items get lost in packaging materials while unpack- ing or they are pre-installed at the factory.

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.

Model G0756 (Mfg. Since 2/13)

Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Avoid using these products to clean machinery.

Many cleaning solvents are toxic if inhaled. Only work in a well-ventilated area.

NOTICE

Avoid chlorine-based solvents, such as acetone or brake parts cleaner, that may damage painted surfaces.

Site Considerations

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 the machine is operated is important for safe operation and lon- gevity of machine 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, if required.

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.

3.Unbolt the machine from the pallet.

4.With another person to help to steady the machine, lift it just enough to clear the pallet and any floor obstacles, then place it in its final position.

Model G0756 (Mfg. Since 2/13)

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

if the machine will be installed in a commercial or workplace setting, or if it is permanently connect- ed (hardwired) to the power supply, local codes may require that it be anchored to the floor.

if not required by any local codes, fastening the machine to the floor is an optional step. if you choose not to do this with your machine, we rec- ommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Anchoring to Concrete Floors

lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a con- crete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. however, anytime local codes apply, you Must follow the anchoring methodology specified by the code.

Figure 7. Popular method for anchoring machinery to a concrete floor.

Arbor/Chuck

Assembly

An arbor is included for the drill chuck that comes with this machine. The following procedure describes how to install the arbor in the chuck.

After the arbor is installed in the drill chuck, it is very difficult to separate the assembly. If you would like to use a different chuck in the future, we suggest using a different arbor.

Important: DO NOT install the drill chuck and arbor assembly until AFTER the test run.

To connect the drill chuck with the arbor:

1.Use acetone or lacquer thinner to clean drill chuck and arbor mating surfaces, especially the bore.

2.Retract the chuck jaws so that they are not exposed.

3.insert the arbor into the drill chuck.

4.hold assembly by the arbor and tap chuck onto a block of wood with moderate force (see Figure 8).

Figure 8. Installing arbor into chuck.

Initial Lubrication

GEARBOX MUST

BE FILLED WITH OIL!

OIL MAY NOT BE

SHIPPED WITH MACHINE!

Refer to Lubrication Section for Correct Oil Type.

To prevent spillage, this machine was shipped from the factory without any oil in it. The head- stock oil reservoir must be properly filled with oil before the drill press can be operated for the first time. Refer to the Lubrication section, beginning on Page 33, for details on how to check and add oil.

Damage caused by running the drill press without oil in the reservoir will not be cov- ered under warranty.

Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an under- sized circuit. Use an electri- cian or a qualified service personnel to ensure a safe power connection.

Before the machine can be connected to the power source, an electrical circuit must be made available that meets the minimum specifications given in Circuit Requirements for 220V on Page 10. If a power circuit has not been prepared for the machine, do that now.

To minimize the risk of electrocution, fire, or equipment damage, all installation work and elec- trical wiring MUst be done by an electrician or qualified service personnel.

Note about extension cords: Using an incor- rectly sized extension cord may decrease the life of electrical components on your machine. Refer to Extension Cords on Page 11 for more infor- mation.

To connect the power cord to the machine:

1.Turn the master power switch to OFF, then open the electrical cabinet door located at the back of the machine.

Model G0756 (Mfg. Since 2/13)

2.Identify the L1, L2, and L3 terminals and the grounding terminal (see Figure 9).

3.thread the power cord through the strain relief shown in Figure 9.

5.Make sure the power cord and wires have slack between the strain relief and terminal connections so that they do not bind, then tighten the strain relief to secure the cord.

Note: The strain relief must be tightened against the outer jacket of the cord. Avoid over-tightening the strain relief or it may crush the cord and cause a short.

6.Test the strain relief to ensure it is properly tightened by pulling the cord from outside the box with light-to-moderate force. When the strain relief is properly tightened, the cord will not move inside the cabinet.

7.Install a NEMA 15-15 plug on the other end of the power cord per the plug manufacturer's instructions.

8.Close and secure the main electrical box door.

9.Plug the power cord into a power source with a matching receptacle, as specified in Circuit Requirements for 220V on Page 10.

Note: If you discover during the Test Run that the drill press will not operate, or that the spindle runs backwards, the drill press may be wired out of phase.

Correcting the phase polarity requires reversing the positions where the L1 and L3 wires are con- nected. Due to the high voltage and risk of serious shock involved, we strongly recommend this pro- cedure only be done by an electrician or qualified service personnel.

Test Run

Once the preceding setup procedures are com- plete, test run your machine to make sure it runs properly and is ready for regular operation.

The test run consists of verifying the following: 1) The motor powers up and runs correctly, 2) the EMERGENCY STOP button and chip guard safety features work correctly, and 3) the motor rotates in the correct direction (machine is not wired out of phase).

Spindle Break-In

Before subjecting the spindle to operational loads, it is essential to complete the break-in process. This helps ensure maximum life of spindle bear- ings and other precision components by thor- oughly lubricating them before placing them under load.

After spindle break-in is complete, we recommend changing headstock and gearbox oil to remove any metal particles or debris that are present from the assembly and break-in process.

The break-in must be performed in succession with the Test Run procedure described in this manual, as the steps in that procedure prepare the drill press for the break-in process.

DO NOT perform this procedure indepen- dently of the Test Run section. The drill press could be seriously damaged if the controls are set differently than instructed in that section.

SECTION 4: OPERATIONS

Operations Overview

The purpose of this overview is to provide the nov- ice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand.

Due to the generic nature of this overview, it is not intended to be an instructional guide. To learn more about specific operations, read this entire manual and seek additional training from expe- rienced machine operators, and do additional research outside of this manual by reading "how- to" books, trade magazines, or websites.

To reduce your risk of serious injury, read this entire manual bEfORE using machine.

To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses and a respirator when operating this machine.

If you are not experienced with this type of machine, WE STRONGLy REcOMMEND that you seek additional training outside of this manual. Read books/magazines or get formal training before beginning any proj- ects. Regardless of the content in this sec- tion, Grizzly Industrial will not be held liable for accidents caused by lack of training.

To complete a typical operation, the operator does the following:

1.Examines the workpiece to make sure it is suitable for drilling.

2.Puts on the required safety gear.

3.Firmly secures the workpiece to the table using a vise or T-slot clamps.

4.Installs the correct cutting tool for the opera- tion.

5.Adjusts table to the correct height, then locks it in place.

Selecting Spindle

RPM

Use the proper spindle speed and feed rate to reduce strain on all moving parts and decrease risk of operator injury.

Prior to drilling, determine the RpM needed for workpiece material then set the spindle speed to the closest available RpM.

To determine the needed RPM:

1.Use the table in Figure 22 to determine the speed required for your workpiece material.

Note: For carbide cutting tools, double the cut- ting speed. These values are a guideline only. Refer to the MACHINERY'S HANDBOOK for more detailed information.

Larger bits turning at slower speeds tend to grab the workpiece aggressively. This can result in the operator's hand being pulled into the bit or the workpiece being thrown with great force. Always clamp the workpiece to the table to prevent injuries.

Figure 22. Cutting speed table for HSS cutting tools.

Drilling Mode

This drill press is designed for vertical drilling and tapping operations. For repeated drilling at the same depth, there is a power downfeed mecha- nism. For tapping convenience, there is an auto- matic clutch used for reversing the direction of the spindle while in tapping mode by pressing one of the buttons at the ends of each course downfeed handle.

Overloading tools or using excessive spin- dle speeds may cause parts or broken tools to hit operator, resulting in serious impact injuries.

-26-

To drill a workpiece:

1. Refer to Controls on Page 4 to understand the functions of each control.

Speed Control Levers

Drilling/Taping Switch

Figure 23. Controls for drilling.

2. Clamp the workpiece to the table, and adjust the depth stop for the needed depth of cut.

Note: Drilling with the quill fully extended can cause tool chatter. For maximum spindle rigidity, keep the spindle retracted into the headstock as far as possible.

3. Put on safety glasses, a face shield, and close the chip guard.

4. Select the "drilling" mode option with the toggle switch.

5. Refer to Selecting Spindle RPM on Page 25, and choose the closest available spindle RPM.

6. turn the Master Power Switch ON.

7. Press the spindle start button and begin the drilling operation.

Model G0756 (Mfg. Since 2/13)

Automatic Power

Downfeed

This drill press comes with automatic downfeed control for repeated drilling operations at the same depth. The automatic downfeed only works in the drilling mode.

Stay clear of coarse downfeed handles while using the automatic downfeed. When the depth stop triggers the lower elevation limit switch, the handles spin rapidly as the spindle returns to its starting position. Failure to stay clear of the handles may result in injury.

To operate the automatic power downfeed:

1.DISCONNECT MACHINE FROM POWER!

2. Select the drilling option with the drilling/tap- ping switch.

3. set the spindle depth stop to the desired position (refer to Page 24).

4. Match the lines on the adjustment knob to select an automatic power downfeed option (see Figure 24).

???There are three options for the power downfeed mechanism that are located on the side of the adjustment knob:

???0.2 is equal to 2mm of downfeed per spindle rotation.

???0.1 is 1mm of downfeed per spindle rotation.

???0.0 disengages the downfeed mecha- nism.

5. Re-connect machine to power.

6. turn the Master Power Switch ON, and press the spindle start button.

7. pull the coarse downfeed handle down towards the front of the machine until the automatic downfeed begins.

When in tapping mode, the spindle direction can immediately alternate between forward and reverse by pressing any of the three buttons at the end of the downfeed handles. This feature is criti- cal to back the tap out of a hole before it bottoms out and snaps off, as well as clearing away waste chips during the tapping process.

Pilot holes must be drilled prior to beginning any tapping operation.

To use tapping mode:

1. DISCONNECT MACHINE FROM POWER!

2.Determine the maximum tapping depth with- out bottoming-out the tap, and adjust the depth stop accordingly.

3. Clamp the workpiece to the table.

4. Put on safety glasses and a face shield. Select tapping mode, and turn the spindle rotation switch counter-clockwise.

5. Install the tap, and apply tapping fluid to the contact point of the tap and workpiece.

6. Connect the machine to power.

7. Select "tapping" mode with the drilling/tap- ping switch

8. Select the appropriate spindle speed. Speeds vary according to the material, bit, and proce- dure. There are several online resources to choose from for calculating spindle speed

9.Press the spindle start button.

10. Begin threading. Without disengaging the tap from the threads, frequently alternate spindle rotation by pressing any end button to reverse spindle and eject chips from the hole. Frequently removing chips will prevent galling and tap breakage.

SECTION 6: MAINTENANCE

To reduce risk of shock or accidental startup, always disconnect machine from power before adjustments, maintenance, or service.

Schedule

Typically, each operator is responsible for ensur- ing proper care of the equipment. We strongly recommend all operators make a habit of follow- ing the daily maintenance procedures.

Ongoing

To reduce the risk of injury and ensure proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations:

???Loose mounting bolts or fasteners.

???Worn, frayed, cracked, or damaged wires.

???Chip guard removed.

???EMERGENCY STOP button not working cor- rectly or not requiring you to reset it before starting the machine again.

???Any other unsafe condition.

Every 8 hour of operation:

???Lubricate the ball oilers (Page 34).

???Check/Add headstock oil (Page 33).

???Check quantity/quality of coolant (Page 20).

Annually:

???Change headstock oil (Page 33).

-32-

Daily, After Operations

???Thoroughly clean the machine and protect all surface areas

???Press the EMERGENCY STOP button and shut OFF the master power switch (to pre- vent accidental startup).

???Remove any rotary tables, vises, fixtures, or workpieces from the table to prevent rusting the table surface.

Annually

???Disconnect machine from power, open elec- trical box, and clean with compressed air.

Cleaning and

Protecting

Metal chips left on the machine will invite oxida- tion and a gummy residue build-up around the moving parts. Use a brush and shop vacuum to remove chips and debris from the working sur- faces of the drill press. Never blow off the drill press with compressed air, as this will force metal chips deep into the mechanisms and may cause injury to yourself or bystanders.

Remove any rust build-up from unpainted cast iron surfaces of your drill press and treat with a non- staining lubricant after cleaning.

Keep unpainted cast iron surfaces rust-free with regular applications of ISo 68 way oil (see Page 30 for offerings form Grizzly).

Model G0756 (Mfg. Since 2/13)

Lubrication

For the quill, table, and column, an occasional application of light machine oil is all that is neces- sary. Before applying lubricant, clean off any dust or metal chips.

Your goal is to achieve adequate lubrication. Too much lubrication will attract dirt and dust. Various parts of your machine could lose their freedom of movement as a result.

Headstock Lubrication

The headstock uses an oil pump to lubricate the gears. For this machine, use Iso 68 machine oil. Check the oil level every day (see Step 4). Change oil annually.

To change oil in headstock:

1. remove the oil fill plug on top of the machine (see Figure 35).

Oil Fill Plug

Oil Drain Plug

Figure 35. Oil fill and drain locations.

2. Remove the drain plug, and allow old oil to drain into an appropriate container.

3. Replace and tighten the drain plug.

4. Fill the headstock with oil to the red mark on the site glass (see Figure 36).

Model G0756 (Mfg. Since 2/13)

Do not fill headstock with oil above the red mark. This could damage the machine and create an overflow of oil.

Red Mark

Site Glass

Location

5. Re-install the oil fill plug.

6.Discard used oil following federal, state, and fluid manufacturer guidelines for proper dis- posal.

Oil Flow Sight Glass

This machine comes with an oil flow sight glass (see Figure 37). Examine the flow sight glass during machine operation to ensure that the oil is properly circulating within the headstock.

If oil is not circulating, and headstock has proper amount of oil, shut down machine immediately and call tech support.

Oil Flow Sight Glass

Figure 37. Oil flow sight glass.

-33-

Ball Oilers

This machine has four ball oilers as shown in Figures 38???39. Use an oil gun fitted with a rub- ber tip wide enough to seal the ball oiler inlet. We do not recommend using metal needle or lance tips, as they can push the ball too far into the oiler, break the spring seat, and lodge the ball in the oil galley.

Push the tip of the oil can nozzle against the ball oiler to create a hydraulic seal, then pump the oil can once or twice. If you see sludge and contami- nants coming out of the lubrication area, continue pumping the oil can until the oil runs clear. When finished, wipe away the excess oil.

Ball Oilers
