•
federal, etc.).
Always use clean, dry air at 90 psig (6.2 bar/620 kPa) maximum air pressure at the inlet. Higher pressure may result in hazardous situations
•
including excessive speed, rupture, or incorrect output torque or force.
Be sure all hoses and ttings are the correct size and are tightly secured.
•
Ensure an accessible emergency shut o valve has been installed in the air supply line, and make others aware of its location.
•
Install a properly sized Safety Air Fuse upstream of hose and use an anti-whip device across any hose coupling without internal shut-o , to
•
prevent hose whipping if a hose fails or coupling disconnects.
Do not use damaged, frayed or deteriorated air hoses and ttings.

EN-1 47146667_ed1
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 objec ts 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.
