Air powered tools can vibrate
in use. Vibration, repetitive
motions or uncomfortable po-

hands and arms. Stop using
any tool if discomfort, tingling
feeling or pain occurs. Seek
medical advice before resum-
ing use.
WARNING
Keep body stance balanced
and firm. Do not overreach
when operating this tool.
•
Do not use this tool if the actual free speed exceeds
the nameplate rpm.
•
Before mounting a wheel, after all tool repairs and
whenever a Grinder is issued for use, check the free
speed of the Grinder with a tachometer to make
certain its actual speed at 90 psig (6.2 bar/620 kPa)
does not exceed the 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 Ingersoll–Rand Wheel Guard
furnished with the Grinder.
•
Do not use a Grinder without the recommended
wheel guard. Do not use any wheel for which the
operating speed listed on the blotter is lower than
the actual free speed of the Grinder.
•
Inspect all grinding wheels for chips or cracks prior to
mounting. 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 the grinding wheel properly fits the
arbor. The wheel should not fit too snugly or too
loosely. Plain hole wheels should have about 0.007"
(0.17 mm) maximum diametral clearance. Do not
use reducing bushings to adapt a wheel to any arbor
unless such bushings are supplied by or recommended
by the wheel manufacturer.

WARNING
WARNING
•
After mounting a new wheel, hold the Grinder
under a steel workbench or inside a casting and run it
for at least 60 seconds. Make certain no one is
within the operating plane of the grinding wheel. If
the wheel is defective, improperly mounted or the
wrong size and speed, this is the time it will usually
fail.
•
When starting 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 the wheel flanges are at least 1/3 the
diameter of the grinding wheel, free of nicks and
burrs and sharp edges. Always use the wheel flanges
furnished by the manufacturer; never use a
makeshift flange or a plain washer.
•
Guard opening must face away from operator.
Bottom of wheel must not project beyond guard.
•
Always use a wheel blotter between each wheel
flange and the wheel. The blotters must be at least
as large in diameter as the wheel flanges.
•
Do not attempt to disassemble the Controller. The
Controller is available only as a unit and is guaranteed
for the life of the tool if it is not abused.
