MAINTENANCE/LUBRICATING AND OPERATING 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 the sander can develop a torque reaction . Reference “GENERAL
POWER TOOL SAFETY PRECAUTIONS” section .
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 trigger fully depressed . It is recommended to use an approved 9 .52 mm (3/8 in) x 8 m (25ft) maximum length airline . It is
recommended that the tool be connected to the air supply as shown in Figure A .
Do not connect the tool to the airline system without incorporating 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 A 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 from your tool distributor .
Adjust airline lubricator equipment such that two drops of 3M™ Air Tool Lubricant PN 20451 (or equivalent 10 centistoke oil) per
minute are provided through the hose to the air inlet of the tool . If excessive oil is noted in the exhaust air, reduce the drip rate of the
airline lubricator equipment accordingly . If such equipment is not used, the tool should be manually lubricated .
To manually lubricate the tool, disconnect the airline and put two to three drops of 3M™ Air Lubricant PN 20451 (or equivalent
10 centistoke oil) into the air 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 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 .
