SAFETY RULES

Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will consid- erably lessen the possiblity of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won???t make up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop. If a procedure feels dangerous, don???t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your personal safety is your responsibility.

ADDITIONAL SAFETY RULES FOR GRINDERS

1. WARNING: Do not operate your grinder until it is completely assembled and installed according to the

instructions.

2. IF YOU ARE NOT thoroughly familiar with the operation of grinders, obtain advice from your supervisor,

instructor or other qualified person.

3.ALWAYS use grinding wheels that have a bore exactly equal to the arbor of the grinder. NEVER attempt to machine an undersize wheel to fit an arbor.

4.NEVER use a chipped or cracked grinding wheel. ALWAYS inspect each wheel before mounting on the grinder. Replace a cracked wheel immediately.

5.ALWAYS maintain a distance of 1/8?? or less between the grinding wheel and the tool rest. Adjust the tool rests as the grinding wheels decrease in size with use.

6.SECURELY tighten tool rests so they cannot shift position while in use.

7.NEVER grind on a cold wheel. The grinder should always be started and run at idle speed for one full minute before applying work.

8.NEVER grind on the side of the wheel. ALWAYS grind on the face of the wheel only.

9.NEVER apply coolant directly to a grinding wheel. Coolant can weaken the bonding strength of the wheel and cause it to fail. Dip the workpiece into water to cool it.

10.SPARKS ARE A HAZARD! NEVER grind near flammable gas or liquids.

11.ALWAYS MAKE SURE the wheel guards and eye shields are in place, properly adjusted and secured.

12.KEEP the spark guards close to the wheel and re-adjust them as the wheel wears.

13.MAKE CERTAIN the blotter and wheel flanges are used to mount the grinding wheels onto the grinder shaft.

14.STAND to one side of the wheel when turning on the power.

15.AVOID awkward hand positions where a sudden slip could cause a hand to move into the grinding wheel.

16.ALWAYS keep hands and fingers away from the grinding wheel.

17.NEVER start the grinder with the workpiece pressed against the grinding wheel.

18.DRESS the wheel on the face only. Dressing the side of the wheel can cause it to become too thin for safe use.

19.DO NOT use a wheel that vibrates. Dress the wheel, replace the wheel, or replace the shaft bearings, if worn.

20.GRINDING CREATES HEAT. Do not touch the work- piece until you are sure it has cooled sufficiently.

21.ALWAYS use grinding wheels that are suitable for the speed of the grinder. NEVER use a wheel that is rated lower than the grinder speed.

22.ALWAYS keep guards in place when using a wire brush or buffing wheel in place of the standard grinding wheel.

23.SHOULD any part of your grinder be missing, dam- aged, or fail in any way, or any electrical component fail to perform properly, shut off switch and remove plug from power supply outlet. Replace missing, damaged or failed parts before resuming operation.

24.THE USE of attachments and accessories not rec- ommended by Delta may result in the risk of injuries.

ASSEMBLY INSTRUCTIONS

ASSEMBLING TOOL RESTS

1.Assemble adjustable tool rest (A) Fig. 1, to left side of tool rest arm (B), as shown, and fasten with one 3/4 inch- long hex head screw and lockwasher (C). Assemble the remaining tool rest to the right side of the other tool rest arm in the same manner. Do not completely tighten hard- ware at this time.

2.Assemble left tool rest assembly (D) Fig. 2, to the inside of left wheel guard (E), and fasten with two 5/8 inch- long screws and flat washers (F) as shown.

3.Assemble right tool rest assembly to the inside of right wheel guard and fasten with two 3/4 inch-long hex head screws and flat washers.

4.Each tool rest assembly (D) Fig. 2, is adjustable so it can be positioned slightly below the centerline of the wheel and as close to the grinding wheel as possible, giv- ing maximum support to the piece that is being ground. A distance of 1/8-inch or less between the grinding wheel and the inside edge of the tool rest should always be main- tained. When the tool rest is positioned correctly, tighten hardware (C) and (F). As the grinding wheel wears down to a smaller diameter, re-adjust the tool rest closer to the wheel. Freehand grinding without the use of a tool rest should always be done on the lower quarter of the wheel.

ASSEMBLING SPARK GUARDS

The spark guard (A) Fig. 3, is to be mounted to the side of each wheel guard, using the 1/4 inch-long screw (B) and washer (C) as shown. The spark guard (A) should be adjust- ed as close as possible to the grinding wheel so that sparks never strike the operator???s hand. As the wheels wear down the spark guard (A) should be adjusted accordingly.

CONNECTING GRINDER TO POWER SOURCE

POWER CONNECTIONS

A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be protected with a 20 Amp fuse. Have a certified electrician replace or repair a worn cord immediately. Before connecting the motor to a power line, make sure the switch is in the ??????OFF??? position and be sure that the electric current is of the same characteristics as stamped on the motor nameplate. Running on low voltage will damage the motor.

WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCA-

TIONS.

MOTOR SPECIFICATIONS

Your grinder is wired for 110-120 volt, 60 HZ alternating current. Before connecting the grinder to the power source, make sure the switch is in the ???OFF??? position.

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and a 3-pole receptacle which will accept the tool???s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the grinder. An undersized cord will cause a drop in line voltage, resulting in loss of power and over-heating. Fig. 7A shows the correct gage to use depending on the cord length. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

GROUNDING INSTRUCTIONS

CAUTION: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR

FROM ELECTRIC SHOCK.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the out- let, have the proper outlet installed by a qualified elec- trician.

Improper connection of the equipment-grounding con- ductor can result in risk of electric shock. The conduc- tor with insulation having an outer surface that is green with or without yellow stripes is the equipment-ground- ing con-

ductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely under- stood, or if in doubt as to whether the tool is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding type plugs and 3-hole receptacles that accept the tool's plug, as shown in Fig. 8.

Repair or replace damaged or worn cord immediately. This tool is intended for use on a circuit that has an outlet and a plug that looks like the one shown in Fig. 8.

A temporary adapter, which looks like the adapter illustrat- ed in Fig. 9, may be used to connect this plug to a

2-pole receptacle, as shown in Fig. 9, if a properly grounded outlet is not available. The temporary adapter should

be used only until a properly grounded outlet can be installed by a qualified electrician. THIS ADAPTER IS NOT APPLICABLE IN CANADA. The green-colored rigid ear, lug, and the like, extending from the adapter must be con- nected to a permanent ground, such as a properly grounded outlet box, as shown in Fig. 9.

CAUTION: IN ALL CASES, MAKE CERTAIN THE RECEP-

TACLE IN QUESTION IS PROPERLY GROUNDED. IF

YOU ARE NOT SURE, HAVE A CERTIFIED ELECTRI-

CIAN CHECK THE RECEPTACLE.

DRESSING A

GRINDING WHEEL

When dressing a grinding wheel use a suitable silicon carbide stick type dresser, as shown in Fig. 11. Bring the dresser forward on the tool rest until it just touches the high point of the face of the wheel and dress the wheel by moving the dresser back and forth. Repeat this operation until the face of the wheel is clean and the corners of the wheel are square.

Fig. 11

GRINDING WHEELS

Use only grinding wheels that are rated higher than the no-load speed of grinders. IMPORTANT: The 8" grinder has a no- load speed of 3600 RPM; the 10" grinder has a no-load speed of 1800 RPM. Use only grinding wheels that have a bore equal to the diameter of the arbor shaft on the grinder. The 8" grinder is supplied with a 5/8" diameter arbor and the 10" grinder has a 1" diameter arbor.

Two aluminum oxide grinding wheels are supplied with your grinder; one 36 grit and one 60 grit. For best grinding results, and to maintain good balance, always keep the wheels properly dressed. Do not force the work against a cold wheel. The grinding wheel should always be run at idle speed for one full minute before applying work. It is recommnended that only balanced wheels be used with your grinder. The use of balanced wheels adds years to the life of the bearings on the grinder and by eliminating the most common source of vibration, more accurate work is accomplished.

CHANGING WHEELS

When changing wheels, simply remove the screws attaching the side covers to the grinder and remove the side cover. To prevent shaft rotation, place a wedge between the grinding wheel and the wheel guard. Facing the grinder, turn the arbor nut down to loosen and up to tighten. IMPORTANT: DO NOT OVERTIGHTEN WHEEL NUTS WHEN INSTALLING

THE WHEELS.
