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.

of a T-20 Torx driver.
Adding Optional Side-Handle
. Disconnect air line from sander.
2. Remove the existing M8 threaded plug and spacer ring assem-
bly (items 25 and 32) from the desired side of the sander with a

Select a suit¬able abrasive and secure it to the disc pad.
Be careful to center the abrasive on the disc pad.
. 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.
0. 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.
. Dust can be highly combustible.
2. 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.
3. Do not exceed maximum recommended air pressure.
Use safety equip¬ment as recommended.
. 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.
5. The tool is not electrically insulated. Do not use where
there is a pos¬sibility of contact with live electricity, gas
pipes, and/or water pipes.
6. This tool is not protected against hazards inherent in
grinding and cut¬ting operations, and no such acces-
sories should ever be attached.

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.
8. Keep hands clear of the spinning pad during use.
9. If the tool appears to malfunction, remove from use im-
mediately and arrange for service and repair.
20. Do not allow the tool to free spin without taking precau-
tions to protect any persons or objects from the loss of
the abrasive or pad ruptures.
2. Immediately release the start handle in the event of any disrup-
tion of pressure; do not attempt to re-start until the disruption
has been corrected.
