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/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 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.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.
