Safety Precautions
1. Read all instructions before using this tool. All operators
must be fully trained in its use and aware of these safety
rules.
2. The tool RPM should be checked on a regular basis to
ensure proper operating speed.
3. Make sure the tool is disconnected from the air supply.
Select a suitable buff pad and secure it to the disc pad. Be
careful to center the buff pad on the disc pad.
4. Always wear required safety equipment when using this
tool.
5. When sanding/buffing always start the tool on the
workpiece. This will prevent gouging due to excess speed
of the buff pad. Stop air flow to the tool as it is removed
from the workpiece.
6. Always remove the air supply to the polisher before fitting,
adjusting or removing the buff pad or disc pad.
7. Always adopt a firm footing and grip and be aware of
torque reaction developed by the polisher.
8. Use only 3M approved spare parts.
9. Always ensure the material being sanded is firmly fixed to
avoid movement.
10. Check hose and fittings regularly for wear. Do not carry
the tool by its hose; always be careful to prevent the tool
from being started when carrying the tool with the air
supply connected.
11. Dust can be highly combustible.
12. If tool is serviced or rebuilt check to ensure that the
maximum tool RPM is not exceeded and that there is no
excessive tool vibration.
13. Do not exceed maximum recommended air pressure.
Use safety equipment as recommended.
14. Prior to installing any sanding or polishing accessory,
always check that its marked maximum operating speed
is equal or higher than the rated speed of this tool.
15. The tool is not electrically insulated. Do not use where
there is a possibility of contact with live electricity, gas
pipes, and/or water pipes.
16. This tool is not protected against hazards inherent in
grinding and cutting operations, and no such accessories
should ever be attached.
17. Take care to avoid entanglement with the moving parts
of the tool with clothing, ties, hair, cleaning rags or loose
hanging objects. If entangled, stop air supply immediately
to avoid contact with moving tool parts.
18. Keep hands clear of the spinning pad during use.
19. If the tool appears to malfunction, remove from use
immediately and arrange for service and repair.
20. Immediately release the start handle in the event of any
disruption of pressure; do not attempt to re-start until the
disruption has been corrected.
21. When tool is not in use, store in a clean, dry environment
free of debris.
22. Recycle or dispose of tool according to Local, State, and
Federal regulations.

Removing and Mounting
Disc and Buffing Pad to
Random Orbital Polisher
Buff pad
1. Disconnect air line from polisher.
2. Peel the old buff pad from the disc pad, by lifting an edge and
puling firmly upward.
3. Inspect the Hook material on the disc pad for damage or debris
clogging the hooks. Clean any debris or buffing compound from
the disc pad surface.
4. Attach a new buff pad to the disc pad, being careful to center it
as well as possible.
5. Apply hand pressure to engage the hooks and loops to firmly
seat the buff pad.
Disc pad
1. Disconnect air line from polisher.
2. Remove the hex wrench from the handle and use it to loosen
the disc pad bolt.
3. After the old disc pad has been removed from the polisher,
inspect the threaded hold in the spindle to ensure that the
threads are free of debris and undamaged.
4. Secure the new disc pad by tightening the disc pad bolt using
the hex wrench.
5. Replace the hex wrench into the handle seat.
An inadequately tightened disc pad bolt could cause the
threaded spindle to break causing damage to the tool and work
piece and possible injury to the operator or bystanders.
