General Instructions for Use
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.
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. See
Maintenance Instructions. 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.

Limitations on Tool Use by Environmental
• Do not operate the tool in excessively hot or cold atmospheres.
• Refer to MSDS of material being worked as to potential for creating fire or
explosion hazard.
• Use appropriate respiratory and skin protection, or local exhaust as stated
in the MSDS of the material being worked on.
Instructions for Setting and Testing
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.
REMOVING AND MOUNTING DISC PADS:
1. Disconnect air line from sander.
2. Remove old disc pad from sander. Hold 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. Secure the sander spindle by hand and tighten the new disc pad securely
to the tool.

Maintenance Instructions

• 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.
• 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 flare 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.
• Refer to MSDS of material being worked as such material could be
deposited on the tool and could come in contact with skin causing
dermatitis, or can be inhaled.
• Be sure to check speed after any maintenance/service operations and at
regular intervals.
• Dispose of tool so it does not impose hazards to personnel and the
environment.
