WARNING
GRINDER SPECIFIC WARNINGS
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 ARO 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 grinding wheel properly fits the
arbor. Do not use reducing bushings to adapt
a wheel to any arbor unless such bushings
are supplied by and 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 operator.
Bottom of wheel must not project beyond
guard.
Always use a wheel blotter between each
wheel flange and the wheel. The blotters must
be at least as large in diameter as the wheel
flanges.
Do not attempt to disassemble the Controller.
The Controller is available only as a unit and
is guaranteed for the life of the tool if it is not
abused.
Before installing a new Cylinder Case
Assembly, always select the correct Assembly
for the motor package you are using.
