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.

25.

WARNING: SOME DUST CREATED BY POWER SANDING, SAWING, GRINDING, DRILLING, AND OTHER CONSTRUCTION ACTIVITIES contains

chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

· lead from lead-based paints,

· crystalline silica from bricks and cement and other

masonry products, and

· arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

SAVE THESE INSTRUCTIONS.

ADDITIONAL SAFETY RULES FOR

GRINDERS

1. DO NOT OPERATE THIS MACHINE until it is assembled and installed according to the

instructions.

2. OBTAIN ADVICE FROM YOUR SUPERVISOR, instructor, or another qualified person if you are not familiar with the operation of this machine.

3. FOLLOW ALL WIRING CODES and recommended electrical connections.

4. USE THE GUARDS WHENEVER POSSIBLE. Check to see that they are in place, secured, and working correctly.

5. ALWAYS USE THE BLOTTER (furnished) and wheel flanges to mount the grinding wheels on the grinder shaft.

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 LIQUIDS. Sparks can create a fire or an explosion.

16. AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause a hand to move into the grinding wheel.

17. KEEP ARMS, HANDS, AND FINGERS away from the grinding wheel.

18. HOLD WORK FIRMLY against the tool rests.

19. DRESS THE GRINDING WHEEL on the face only. Dressing the side of the grinding wheel could cause it to become too thin for safe use.

20. GRIND A WORKPIECE using the face of the grinding wheel only.

21. NEVER APPLY COOLANT directly to the grinding wheel. Coolant can weaken the bonding strength of the grinding wheel and cause it to fail. Dip the workpiece in water to cool it.

22. DO NOT TOUCH the ground portion of a workpiece until it has cooled sufficiently. Grinding creates heat.

23. TURN THE MACHINE “OFF” AND DISCONNECT THE MACHINE from the power source before installing or removing accessories, before adjusting or changing set-ups, or when making repairs.

24.. TURN THE MACHINE “OFF”, disconnect the machine from the power source, and clean the table/work area before leaving the machine. If your machine has a switch lock-out feature, LOCK THE SWITCH IN THE “OFF” POSITION to prevent unauthorized use.

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

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.

WARNING: IN ALL CASES, MAKE CERTAIN THE

RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

1. All grounded, cord-connected machines:

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.

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

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.

Repair or replace damaged or worn cord immediately.
