To comply with OSHA Occupational Noise Exposure Standard
Number 1926.52, this polisher is equipped with an internal Silencer
System. When the polisher is operated correctly at 85 PSI, the sound
level emitted should be less than 80 dBA. The internal Silencer
System is also used to maintain a constant back pressure inside the
tool, to prevent the rotor assembly from exceeding the max speed
of the bearings; this helps prevent the polisher from exceeding the
recommended 4,000 RPM. The exhaust hose for this tool also helps
to reduce the noise level by venting the exhaust air and residual
air-line, thus eliminating the risk of excess rust inhibitor oil dripping
on the work piece.
Tools sent in for repair, where the body gasket or silencer is removed
or modified, are not covered under our Limited Warranty.
ReVeRsIble sIde hANdle
Attach the handle into the threaded socket on either the left or right
