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 rec-
ommended wheel guard. Do not use any wheel for which the operat-
ing 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 y o 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 46ARA grinders equipped with collets are intended 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 (4604A, 405A Guards).
5. The Model 46ARA Grinders 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 that prevent accidental startup are available from
the manufacturer.(402-26).
8. Before mounting or removing a wheel, disconnect grinder from
air supply. The wheel should t properly on arbor, do not use bush-
ings or wheel anges to adapt a wheel to any
arbor unless recommended by the manufacturer.
(Wheel anges should be at least 1/3 the diam-
eter of the grinding wheel.)
9. Wear safety goggles and other protective
clothing. Continuous exposure to vibration may
cause injury to your hands and arms.(See regu-
lations.)
10.Properly maintained air tools are less likely
to fail or cause accidents. If tool produces an
unusual sound or vibrations repair immediately.
11. NEVER MODIFY ANY PART OF THE
TOOL OR ACCESSORIES!!
