Do not use this tool for purposes other than those recommended.
Use accessories recommended by Ingersoll Rand.
Do not use this tool if the actual free speed exceeds the rated rpm. Check the free speed of the Grinder before mounting a wheel, after
all tool repairs, before each job and after every 8 hours of use. Check speed with a calibrated tachometer, without the abrasive product
installed.
Do not use any wheel or other abrasive accessory whose maximum operating speed, as de ned by its manufacturer, is less than the rated
speed of the Grinder.
Use only grinding wheels and other abrasive accessories recommended for this tool in Ingersoll Rand technical literature.
Inspect all grinding wheels for chips or cracks prior to mounting. Do not use a wheel that is chipped, cracked or otherwise damaged.
Inspect arbor, threads & clamping devices for damage & wear prior to mounting wheel or other abrasive accessory.
Do not use a grinding wheel that has been exposed to freezing temperatures, extreme temperature changes, high humidity, solvents, water
or other liquids.
Make certain grinding wheel or other abrasive accessory properly ts the spindle. The wheel should not t too snugly or too loosely. Plain
hole wheels should have about .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 and recommended by the wheel manufacturer.
Blotters shall always be used between anges and abrasive wheel surfaces to ensure uniform distribution of ange pressure (except type 27
& 28 wheels) and shall cover the entire contact area of the wheel ange.
Always use the wheel anges furnished by the manufacturer and appropriate for the wheel size and type. Never use a makeshift ange or
plain washer. Flanges should be in good condition and free of nicks, burrs and sharp edges.
Ensure that the thread type and size of the threaded abrasive product exactly matches the thread type and size of the spindle.
Prevent the spindle end from touching the bottom of the hole of cups, cones or plugs with threaded holes, intended to be mounted on
machine spindles, by comparing dimensions and other relevant data for them.
Ensure that the grinding wheel or other abrasive accessory is correctly mounted and tightened before use.
Before starting this tool, the operator shall make sure that no one is in the plane of rotation.
Wear Personal Protective Equipment and remove ammable objects from the work area to ensure that sparks and debris do not create a
hazard when using this tool.
After mounting a wheel or other abrasive accessory, the Grinder shall be run in a protected enclosure, at gradually increasing speed, for at
least 60 seconds. Make certain no one is in front of or in line with the wheel or other abrasive accessory. Be aware that it may fail at this time
if it is defective, improperly mounted or the wrong size and speed. Stop immediately if considerable vibration or other defects are detected.
Shut o the air supply and determine the cause.
Do not use this tool on materials whose dust or fumes can cause a potentially explosive environment.
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.
If the grinder is dropped or bumped, turn o the air supply and carefully examine the grinding wheel or other abrasive accessory. Discard
it if damaged, chipped or cracked. Before reuse, run the grinder in a protected enclosure following the same precautions used after rst
mounting.
Before a grinder is put down, the throttle shall be released and the wheel or other accessory shall come to a stop. Tool rests, hangers, and
balancers are recommended.
Additional Warnings for Guarded Grinders
Do not use this Grinder without the furnished Wheel Guard.
Incorrect combinations of grinder wheel, wheel guard and tool speed could result in injury. Ensure that combinations are correct per the
Product Speci cations.
Always replace a damaged, bent or severely worn wheel guard. Do not use a wheel guard that has been subjected to wheel failure.
Guard opening must face away from the operator. Bottom of wheel must not project beyond guard.
Additional Warnings for Use of Cut-o Wheels (Type 1 and 27A)
When cutting, support the workpiece so the slot is kept at constant or increasing width during the whole operation.
If the abrasive product gets jammed in a cut slot, shut o the grinder and ease the wheel free. Check that the wheel is still correctly secured
and not damaged before continuing the operation.
A cut-o wheel shall not be used for side grinding.
Additional Warnings for Unguarded Grinders
Do not use an unguarded grinder unless used for internal work and only operated when the work o ers protection.
Do not use any Type 1 wheels that are larger than 2 inches (50mm) in diameter or more than 1/2 inch (13mm) thick, or that operate at
peripheral speeds greater than 1800 Surface Feet Per Minute (9 Surface Meters per Second).
Do not use any small cones and plugs and threaded hole pot balls unless their size does not exceed 3 inches (75mm) in diameter by 5 inches
(125mm) long.
Do not use other types of grinding wheels. Do not use wire wheels with a diameter that is greater than 2 inches (50mm) or cut-o wheels
with this unguarded grinder.
