Ingersoll-Rand 4578217 manual Using the Tool Continued, Warning Symbol Identification

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 the operator. Bottom of wheel must not project beyond guard.

•Series 325SC & XC Grinders have a free speed of

25 000 rpm; Series 330SC & 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.

•Always match collet size with accessory shank size.

•Always insert tool shank no less than 3/8” (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).

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.
