GRINDER SPECIFIC WARNINGS

FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY. Do not use this tool if actual free speed exceeds the

nameplate rpm. Before mounting a wheel, after any tool repair or

whenever a Grinder is issued for use, check free speed of Grinder with a tachometer to make certainits actual speed at 90 psig (6.2 bar/620 kPa) does notexceed rpm stamped or printed on the nameplate. Grinders in use on the job must be similarly checked at least once each shift.

Always use the recommended IngersollRand Wheel Guard furnished with the Grinder.

Do not use any grinding wheel, bur or other accessory having a maximum operating speed less than the free speed of the Grinder in which it is being used. Always conform to maximum rpm on grinding wheel blotters.

Inspect all grinding wheels for chips or cracks prior tomounting. Do not use a wheel that is chipped or cracked or otherwise damaged. Do not use a wheel that has been soaked in water or any other liquid.

Make certain grinding wheel properly fits the arbor. Do not use reducing bushings to adapt a wheel to any arbor unless such bushings are supplied by and recommended by the wheel manufacturer.

After mounting a new wheel, hold the Grinder under a steel workbench or inside a casting and run itfor at least 60 seconds. Make certain no one is within the operating plane of the grinding wheel. If a wheel is defective, improperly mounted or the wrong size and speed, this is the time it will usually fail.

When starting with a cold wheel, apply it to the work slowly until the wheel gradually warms up.Make smooth contact with the work and avoid any bumping action or excessive pressure.

Always replace a damaged, bent or severely worn wheel guard. Do not use a wheel guard that has been subjected to a wheel failure.

Make certain wheel flanges are at least 1/3 the diameter of grinding wheel, free of nicks, burrs and sharp edges. Always use wheel flanges furnished by the manufacturer; never use a makeshift flange or aplain washer. Tighten Flange Nut securely.

Guard opening must face away from operator. Bottom of wheel must not project beyond guard.

Series HD120 and HX120 Grinders have a free speed of 12,000 rpm; Series HD150 and HX150 Grinders have a free speed of 15,000 rpm and Series HD180, HX180 and HXD180 Grinders have a freespeed of 18,000 rpm, when operated at 90 psig (6.2bar/620 kPa) air pressure. Operation at higher airpressure will result in excessive speed. (continued)

GRINDER SPECIFIC WARNINGS

Always match collet size with accessory shank size. Always insert tool shank no less than 10 mm in the

collet. Tighten Collet Nut securely to prevent accessory from working out during operation of theGrinder. Check tightness of Collet Nut before

operating the Grinder. Pay particular attention to the fact that allowed speed of a mounted point is lowered when the length of the shaft is increased between end of collet and mounted point (overhang).

WARNING: Incorrect combinations of grinding wheel, wheel guard and tool speed could result in injury. Correct combinations are specified below:
