13) Check hoses and fittings regularly for wear.

Replace if necessary. Do not carry the tool by
its hose. Ensure the hand is removed from the
on/off trigger when carrying the tool with the
air supply connected.

14) Take care against entanglement of moving tool

parts with clothing, ties, hair, cleaning rags,
etc. This will cause the body to be drawn
towards the tool and can be very dangerous. 

15) It is expected that users will adopt safe 

working practices and observe all relevant
legal requirements when installing, using or
maintaining the tool.

16) Only install the tool when an easily accessible

and easily operable on/off switch is
incorporated in the air supply.

17) Take care that the tool exhaust air does not

cause problems or blow onto another person.

18) Never lay a tool down unless the working

attachment has stopped moving.

19) Always begin sanding with sandpaper coarse

enough to remove high spots on the surface to
be sanded. Progress to finer grit sandpaper
until the desired finish is obtained.

20) Always use sandpaper appropriate for the

surface being sanded.

Safety Rules For Pneumatic Tools

1)  Inspect the air hose for cracks or other 

problems. Replace the hose if worn.

2)

Never point an air hose at another person.

3)

Disconnect the tool when not in use, or before
performing service or changing accessories.

4)

Use proper hoses and fittings. Never use 
quick-change couplings attached to the tool.
Instead, add a hose and coupling between the
tool and the air supply.

The recommended hook-up is shown in figure A.
Pneumatic tools operate on a wide range of air
pressures. For maximum efficiency and longer tool
life, the pressure of the air supplied to these tools
should not exceed the rated PSI at the tool when
the tool is running. Using a higher than rated
pressure will cause faster wear and drastically
shorten the tool's life. A higher air pressure can
also cause an unsafe condition.

The inside diameter of the hose should be
increased to compensate for unusually long air
hoses (over 25 feet). Minimum hose diameter
should be 3/8" I.D. and fittings should have the
same inside dimensions.

The use of air line lubricators and air line filters is
recommended to prevent water in the line that can
damage the tool. Drain the air tank daily. Clean the
air inlet filter screen on at least a weekly schedule
to remove accumulated dirt or other matter that
can restrict air flow.

The tool's air inlet used for connecting an air
supply has standard 1/4" NPT American thread.

PAD INSTALLATION

Secure the inertia wheel with the spanner handle (See Figure B). Place the hold-down nut through the center hole

of the sandpaper and backing pad. Tighten by turning nut clockwise (See Figure C) with a flat-tip screwdriver.

PAD REMOVAL

Remove pad by turning nut counter-clockwise.
