GENERAL 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 considerably lessen the possibility 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.

This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not be modified and/or used for any application other than that for which it was designed. If you have any questions relative to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should be performed on the product.

6.

USE ONLY GRINDING WHEELS suitable for the speed of the machine.

7.

USE ONLY GRINDING WHEELS that have a bore exactly equal to the arbors of the machine. Never attempt to machine an undersized wheel to fit an arbor.

8.

DO NOT USE A GRINDING WHEEL THAT

VIBRATES. Dress the grinding wheel, replace it, or replace the bearings of the shaft.

9.

INSPECT GRINDING WHEELS BEFORE START-

ING THE MACHINE for cracks or chips. REPLACE

DAMAGED GRINDING WHEELS immediately.

10. ADJUST SPARK GUARDS close to the grinding wheel, and re-adjust as the wheel wears down.

11. ADJUST TOOL RESTS close to the grinding wheel

(1/8" (3.8mm) separation or less). Tighten the tool rest securely to prevent shifting positions.

12. STAND TO ONE SIDE before turning the machine

“ON”.

13. NEVER GRIND ON A COLD GRINDING WHEEL.

Run the grinder at idle speed for one full minute before applying the workpiece.

14. NEVER START THE MACHINE with the workpiece against the grinding wheel.

15. NEVER GRIND NEAR FLAMMABLE GAS OR

POWER CONNECTIONS

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the motor to the power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the motor.

WARNING: DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the “OFF” position.

GROUNDING INSTRUCTIONS

WARNING: THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM

ELECTRIC SHOCK.

1. All grounded, cord-connected machines: 2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150 volts:

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 machine is equipped with an electric cord having an equipmentgrounding 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 outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. B 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.

The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must be held in place with a metal screw.

NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

Check with a qualified electrician or service personnel if t h e g r o u n d i n g i n s t r u c t i o n s a r e n o t c o m p l e t e l y understood, or if in doubt as to whether the machine is properly grounded.

WARNING: IN ALL CASES, MAKE CERTAIN THE

RECEPTACLE IN QUESTION IS PROPERLY

Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine’s plug, as shown in

Fig. A.

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 matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

WARNING: To reduce the risk of fire, use 40 watt or less, 120 volt, reflector track type light bulb (not supplied). A standard household light bulb should not be used. The reflector track type light bulb should not extend below the lamp shade.

GRINDING WHEELS

WARNING: THE USE OF ACCESSORIES AND

ATTACHMENTS NOT RECOMMENDED BY DELTA

MAY RESULT IN RISK OF INJURIES. Grinding wheels used with this grinder should be rated for 3600 RPM or higher and be 8" in diameter with a 1/2" arbor hole.

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

DRESSING A

GRINDING WHEEL

When dressing a grinding wheel use a suitable silicon carbide stick type dresser, as shown in Fig. 12. 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. ALWAYS maintain a distance of 1/8" or less between the grinding wheel and the tool rest. Adjust the tool rests and spark guards as the grinding wheels decrease in size with use.
