* Declared noise levels; measurements carried out in accordance with standard EN ISO 15744 and EN ISO 11203.
** Declared vibration levels in accordance with EN ISO 12096; measurements carried out in accordance with standard EN ISO 28927-3.
IMPORTANT NOTE: The noise and vibration values stated in the table are from laboratory testing in conformity with stated codes and standards and are not
sufficient risk evaluation for all exposure scenarios. Values measured in a particular work place may be higher than the declared values. The actual exposure
values and amount of risk or harm experienced to an individual is unique to each situation and depends upon the surrounding environment, the way in which the
individual works, the particular material being worked, work station design, as well as upon the exposure time and the physical condition of the user. 3M™ cannot
be held responsible for the consequences of using declared values instead of actual exposure values for any individual risk assessment.
Operating & Maintenance Instructions
PRIOR TO THE OPERATION
The tool is intended to be operated as a hand held tool. It is always recommended that while using the tool operators stand on a solid floor in a secure position
with a firm grip and footing. Be aware that the sander can develop a torque reaction. See the section "SAFETY PRECAUTIONS".
Use a clean lubricated air supply that will give a measured air pressure at the tool of 6.2 bar (90 psig) when the tool is running with the lever fully depressed. It is
recommended to use an approved 10 mm (3/8 in) x 8 m (25 ft) maximum length airline. Connect the tool to the air supply as shown in Figure 1. Do not connect
the tool to the airline system without an easily accessible air shut off valve. It is strongly recommended that an air filter regulator and lubricator (FRL) be used
as shown in Figure 1as this will supply clean lubricated air at the correct pressure to the tool. In any case appropriate air pressure regulators shall be used at
all times while operating this tool where the supply pressure exceeds the marked maximum of the tool. Details of such equipment can be obtained for your tool
distributor. If such equipment is not used the tool should be manually lubricated. To manually lubricate the tool disconnect the airline and put 2 to 3 drops of
suitable pneumatic motor lubricating oil such as 3M™ Air Tool Lubricant PN 20451Fuji Kosan FK-20 Mobil ALMO 525 or Shell TORCULA
(inlet) of the tool. Reconnect tool to the air supply and run tool slowly for a few seconds to allow air to circulate the oil. If the tool is used frequently lubricate it on
a daily basis or lubricate it if the tool starts to slow or lose power. It is recommended that the air pressure at the tool be 6.2 bar (90 psig) while the tool is running
so the maximum RPM is not exceeded. The tool can be run at lower pressures but should never be run higher than 6.2 bar (90 psig). If run at lower pressure the
performance of the tool is reduced.

Safety Precautions

1. Read all instructions before using this tool. All operators must be fully

3. Make sure the tool is disconnected from the air supply. Select a suitable
abrasive and secure it to the pad. Be careful to center the abrasive on the
0.79
pad.
0.87
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 sander before fitting, adjusting or
removing the abrasive or 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. Keep working area clean.
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 orbiting 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. Operate tool in a well lit work area.
23. Recycle or dispose of tool according to Local, State, and Federal
Regulations.
24. Whenever performing maintenance procedures, use care to avoid
exposure to any hazardous substances deposited on the tool as a result of
work processes. Also, refer to warnings related to dust exposure.

SETTING & TESTING TOOL SPEED:
1. Ensure the Activation Lever is not depressed.
2. Connect the compassed air line.
3. Press the Activation Lever and move the Speed Control to set desired
speed.
4. Use a Vibratory Tachometer to check the speed.
5. Check speed regularly.
Recommended Accessories - 3M™ Pads
3M Pads are perfectly mated for use on the 3M Sander. Constructed from
premium, industrial-quality materials and featuring a riveted fiberglass and
steel hub with molded urethane, their durability and precise construction
are the ideal complement to the performance of the 3M Sander. See Product
Configuration/Specifications table for the correct replacement pad for a
particular model.
See 3M ASD Accessories to Optimize Performance catalog
61-5002-8098-9 and Engineered Metalworking Solutions catalog
61-5002-8097-1 for additional accessories.
Setting Up Pad on Orbital Sander
1. Disconnect air line from sander.
2. Remove old pad from sander by removing the 4 screws with the wrench
supplied with the tool.
3. Position the new pad to align the screws with the threaded holes and
tighten securely.
An inadequately tightened pad could cause the threaded shaft to break
causing damage to the tool and work piece and possible injury to the operator
or bystanders.
