• 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 defined by its
manufacturer, is less than the rated speed of the
Grinder.
• 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 ex-
posed to freezing temperatures, extreme tempera-
ture changes, high humidity, solvents, water or
other liquids.
• Make certain grinding wheel or other abrasive ac-
cessory properly fits the spindle. The wheel should
not fit 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 flanges
and abrasive wheel surfaces to ensure uniform
distribution of flange pressure (except type 27 & 28
wheels) and shall cover the entire contact area of
the wheel flange.
• Always use the wheel flanges furnished by the
manufacturer and appropriate for the wheel size
and type.
Never use a makeshift flange 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 spin-
dles, by comparing dimensions and other relevant
data for them.
• Ensure that the grinding wheel or other abra-
sive 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
flammable 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 ac-
cessory, 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 acces-
sory. 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 off 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 gradu-
ally warms up. Make smooth contact with the work, and avoid any bumping
action or excessive pressure.
• If the grinder is dropped or bumped, turn off 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 fol-
lowing the same precautions used after first 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 Specifica-
tions.
• 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 Unguarded Grinders
• Do not use an unguarded grinder unless used for internal work and only oper-
ated when the work offers protection.
NEVER MODIFY ANY PART OF
THIS TOOL!!!
Serious injury can result.
