* Declared noise levels; measurements carried out in accordance with standard EN ISO 15744.
** 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 1 as 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 20451, Fuji Kosan FK-20 or Mobil ALMO 525 into the hose end (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.

Lubricate the angle head every 6-8 working hours with premium grease with the following properties:
- High and low temperature performance
- Shear stable
- Anti-wear protection
- Low viscosity base fluid for high speed application
- Very low coefficient of friction
Fuchs Renolit AX S2 or equal is recommended. Grease gun and grease available from your grease supplier.
