* Declared noise levels; measurements carried out in accordance with standard EN ISO 15744.
** Declared vibration levels in accordance with EN ISO 20643 and 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 suffi cient risk
evaluation for all exposure scenarios. 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.
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 fl oor, in a secure position with a fi rm
grip and footing. Be aware that the tool can develop a torque reaction. See the section in "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 12.7 mm (1/2 in) x 8 m (25 ft) maximum length airline for tool 28825 or an approved 9.5 mm (3/8 in) x 8 m (25 ft) maximum length airline
for tool 88577. Connect the tool to the air supply as shown in Figure A. Do not connect the tool to the airline system without an easily accessible air shut off valve. It is strongly
recommended that an air fi lter, 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 air line 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 air line 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 Tool 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 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.

Proper gear set lubrication is critical to maximizing tool life and performance. To lubricate the gear set inside the tool angle head, remove Oiler Screw (item 11) from Angle
Head (item 16) and add fi ve to ten drops of 3M™ Gear Oil PN 28827 (or equivalent 68 centistoke oil) to Wick (item 8) every eight hours of tool operation. If excessive oil is
noted on the Spindle (item 5) during operation, reduce the number of drops provided accordingly.
