Using the Tool (Continued)
•
Keep hands, loose clothing, long hair and jewelry
away from working end of tool.
•
Power tools can vibrate in use. Vibration, repetitive
motions or uncomfortable positions may be harmful to
your hands and arms. Stop using any tool if
discomfort, tingling feeling or pain occurs. Seek
medical advice before resuming use.
•
Keep body stance balanced and firm. Do not
overreach when operating this tool. Anticipate and be
alert for sudden changes in motion, reaction torques,
or forces during start up and operation.
•
Tool and/or accessories may briefly continue their
motion after throttle is released.
•
To avoid accidental starting -- ensure tool is in “off”
position before applying air pressure, avoid throttle
when carrying, and release throttle with loss of air.
•
Ensure work pieces are secure. Use clamps or vises to
hold work piece whenever possible.
•
Do not carry or drag the tool by the hose.
•
Do not use power tools when tired, or under the
influence of medication, drugs, or alcohol.
•
Never use a damaged or malfunctioning tool or
accessory.
•
Do not modify the tool, safety devices, or accessories.
•
Do not use this tool for purposes other than those
recommended.
•
Use accessories recommended by Ingersoll--Rand.
•
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 certain
its actual speed at 90 psig (6.2 bar/620 kPa) does not
exceed 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 Ingersoll--Rand
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 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.
•
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
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 a
plain washer. Tighten Flange Nut securely.
•
Guard opening must face away from operator.
Bottom of wheel must not project beyond guard.
•
Always match collet size with accessory shank size.
•
Always insert tool shank no less than 3.8
I
(10 mm) in
the collet. Tighten Collet Nut securely to prevent
accessory from working out during operation of the
Grinder. 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).
•
Series 325SC and XC Grinders have a free speed of
25 000 rpm; Series 330SC and XC Grinders have a
free speed of 30 000 rpm; Series 335SC Grinders have
a free speed of 35 000 rpm, when operated at 90 psig
(6.2 bar/620 kPa) air pressure. Operation at higher air
pressure will result in excessive speed.
The use of other than genuine Ingersoll--Rand replacement parts may result in safety hazards, decreased tool performance, and
increased maintenance, and may invalidate all warranties.
Repairs should be made only by authorized trained personnel. Consult your nearest Ingersoll--Rand Authorized Servicenter.
