This tool is designed to operate
on 90 psig (6.2 bar) maximum
air pressure with 1/4” (8 mm)
hose. Do not use a grinder without
recommended wheel guard. Do
not use any wheel for which the
operating speed listed is lower
than the actual free speed of the
Grinder.
SAFETY
1. Before operation check
spindle speed with a tachometer.
If the RPM exceeds the rated
speed stamped on tool, servicing
is required.
2. Inspect grinding wheels for
bends, chips, nicks, cracks or
severe wear. If the wheel has any
of these, or has been soaked in
liquids do not use. On brushes
check for loose wires that may fly
off in operation.
3. Start new grinding wheels
under a steel bench. Run at full
throttle for one minute. Defective
wheels usually come apart im-
mediately. When starting a cold
wheel apply to work slowly, allow
wheel to warm gradually.
4. Model 46RAC grinders
equipped with collets are intend-
ed for mounted wheels,points
and carbide burrs. They are
not guarded for type 1 wheels.
If you have a type 1 wheel
application,please purchase a
guard (540875).

are equipped with a guard from
the manufacturer. A guard is not
needed for :a.) mounted wheels
two inches (50 mm) or smaller;
b.) grinders used for internal
work, while within the work being
ground.
6. At least one-half of the
mandrel length (i.e. mounted
wheel, burr, etc.) must be
inserted into the collet. Secure
collet chuck tightly.
7. Safety levers are available
from the manufacturer.(402-26).
8. Before mounting or remov-
ing a wheel, disconnect grinder
from air supply. The wheel should
fit properly on arbor, do not use
bushings or wheel flanges to
adapt a wheel to any arbor un-
less recommended by the manu-
facturer. (Wheel flanges should
be at least 1/3 the diameter of
the grinding wheel.)

other protective clothing. Con-
tinuous exposure to vibration
may cause injury to your hands
and arms.(See regulations.)
