after every 8 hours of use. Check speed with a
calibrated tachometer, without the abrasive
product installed.
Do not use any grinding wheel, burr or other
•
accessory having a maximum operating speed less
that the free speed of the Grinder in which it is
being used.

Make certain grinding wheel properly fits the
arbor. 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.
Make certain the wheel flanges are at least 1/3 the
diameter of the grinding wheel. Flanges should be
in good condition and free of nicks, burrs and
sharp edges. Always use the wheel flanges
furnished by the manufacturer; never use a
makeshift flange or plain washer.
Do not use this Grinder without the furnished
Wheel Guard.
Always replace a damaged, bent or severely worn
wheel guard. Do no 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.
After mounting a wheel, 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 grinding wheel. Be
aware that the wheel 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.
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 off the
air supply and carefully examine the grinding
wheel, burr or other accessory. Discard it if
damaged, chipped or cracked. Before reuse, run
the grinder in a protected enclosure following the
same precautions used after first mounting a
wheel.
Before starting a grinder, the operator shall make
sure that no one is in the unguarded plane of wheel
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.
Do not use this tool on materials whose dust or
fumes can cause a potentially explosive
environment.
Before a grinder is put down, the throttle shall be
released and the wheel shall come to a stop. Tool
rests, hangers, and balances are recommended.
Do not attempt to disassemble the Controller. The
Controller is available only as a unit.
