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 abrasive and secure it to the disc pad. Be careful to center
the abrasive on the disc pad.
4. Always wear required safety equipment when using this tool.
5. When sanding always start the tool on the workpiece. This will
prevent gouging due to excess speed of the abrasive. Stop air flow
to the tool as it is removed from the workpiece.
6. Always remove the air supply to the sander before fitting, adjusting
or removing the abrasive or disc pad.
7. Always adopt a firm footing and grip and be aware of torque
reaction developed by the sander.
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. Do not allow the tool to free spin without taking precautions to
protect any persons or objects from the loss of the abrasive or pad
ruptures.
21. 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.
22. When tool is not in use, store in a clean, dry environment free of
debris.
23. Recycle or dispose of tool according to Local, State, and Federal
regulations.

Removing and Mounting Disc
Pad to Random Orbital Sander
1. Disconnect air line from sander.
2. Remove old disc pad from sander by inserting the wrench, supplied with the
tool, between the rubber shroud and the disc pad. Use the wrench to secure
the sander spindle while turning the disc pad counter clockwise.
3. After the old disc pad has been removed from the sander, inspect the
threaded hole in the spindle to ensure that the threads are free of debris
and undamaged.
4. Ensure that the phenolic washer is in place around the threaded shaft of the
new disc pad.
5. Secure the sander spindle with the wrench and tighten the new disc pad
securely to the tool.
An inadequately tightened disc pad could cause the threaded shaft to break
causing damage to the tool and work piece and possible injury to the operator
or bystanders.
