Delta GR150 instruction manual Additional Safety Rules, Do not Overtighten Wheel NUT

ADDITIONAL SAFETY RULES

Failure to follow these rules may result in serious personal injury.

1.DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury.

2.OBTAIN ADVICE from your supervisor, instructor or another qualified person if you are not thoroughly familiar with the operation of this machine. Knowledge is safety.

3.FOLLOW ALL WIRING CODES and recommended electrical connections to prevent shock or electrocution.

4.ALWAYS USE THE PROVIDED BLOTTER AND WHEEL FLANGES to mount the grinding wheels on the grinder shaft to prevent wheel damage or accidental separation. Separation can result in fragments flying off the wheel at high speeds.

5.USE ONLY WHEELS suitable for the speed of the machine. Unsuitable grinding wheels can come apart, throwing fragments out at high speeds.

6.USE ONLY WHEELS that have a bore exactly equal to the arbors of the machine. Never attempt to machine an undersized wheel to fit an arbor. Unsuitable grinding wheels can come apart, throwing fragments out at high speeds.

7.DO NOT OVERTIGHTEN WHEEL NUT.

8.DO NOT USE A WHEEL THAT VIBRATES. Dress the grinding wheel, replace it or replace the bearings of the shaft. Unsuitable grinding wheels can come apart, throwing fragments at high speeds.

9.INSPECT WHEELS before starting the machine for cracks or fragments. REPLACE DAMAGED WHEELS immediately. Parts of the wheel can be thrown at high speeds causing serious injury.

10.ADJUST EYE SHIELDS close to the grinding wheel, and re-adjust as the wheel wears down. Flying sparks are dangerous and can cause fires or explosions.

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

12.ADJUST TOOL RESTS close to the grinding wheel (1/8" separation or less). Tighten the tool rest securely to prevent shifting positions, and re- adjust as the wheel wears down. The workpiece can be drawn into the wheel, causing damage to the workpiece and/or serious injury.

13.STAND TO ONE SIDE before turning the machine "ON". Loose fragments or wheel parts could fly from the wheel at high speeds.

14.NEVER GRIND ON A COLD WHEEL. Run the grinder for one full minute before applying the workpiece. A cold wheel has a tendency to chip. Those fragments could fly from the wheel at high speeds.

15.NEVER START THE MACHINE with the workpiece against the grinding wheel. The workpiece can be drawn into the wheel, causing damage to the machine and/or serious injury.

16.CLEAN THE MACHINE thoroughly when processing different types of workpieces (wood, steel or aluminum). Combining wood and metal dust can create an explosion or fire hazard. DO NOT GRIND OR POLISH MAGNESIUM. Fire will result.

17.NEVER GRIND NEAR FLAMMABLE GAS OR LIQUIDS. Sparks can create a fire or an explosion.

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

19.KEEP ARMS, HANDS, AND FINGERS away from the wheel. The abrasive surfaces can cause serious injury.

20.HOLD THE WORKPIECE FIRMLY against the tool rest. Loss of control of the workpiece can cause serious injury.

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

22.GRIND A WORKPIECE using the face of the grinding wheel only. Loss of control of the workpiece can cause serious injury.

23.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.

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

25.PROPERLY SUPPORT LONG OR WIDE WORK- PIECES. Loss of control of the workpiece can cause serious injury.

26.NEVER PERFORM LAYOUT, ASSEMBLY or set-up work on the table/work area when the machine is running. A sudden slip could cause a hand to move into the wheel. Severe injury can result.

27.TURN THE MACHINE "OFF", disconnect the machine from the power source, and clean the table/work area before leaving the machine.

28.ADDITIONAL INFORMATION regarding the safe and proper operation of power tools (i.e. a safety video) is available from the Power Tool Institute, 1300 Sumner Avenue, Cleveland, OH 44115-2851 (www.powertoolinstitute.com). Information is also available from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201. Please refer to the American National Standards Institute ANSI 01.1 Safety Requirements for Woodworking Machines and the U.S. Department of Labor OSHA 1910.213 Regulations.
