AIR VALVE LEVER
The valve lever controls the fl ow of air through the tool.
It has two positions- ON or OFF. Run the tool at the
recommended range of 85-90 PSI, with the lever pointing
to the ON position. This will produce 3,500 RPM. Do not
try to vary the speed. The tool works best at full throttle
only. Do not attempt to exceed the recommended speed
by excess pressure.
WATER CONTROL VALVE
This valve lets you adjust the fl ow of water through the spindle. It may be used to
shut off the water entirely when changing discs. When storing the tool overnight,
open the valve and drain all water from the supply hose and tool.
SILENCER / MUFFLER
To comply with OSHA Occupational Noise Exposure Standard Number 1926.52,
this polisher is equipped with a Silencer. When the polisher is operated correctly
at 87 PSI, the sound level emitted should be 80 dBA. The Silencer is also used
to maintain a constant back pressure inside the tool; this helps to prevent it from
exceeding the recommended 3,500 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 lubricant drip-
ping on the work piece.
Silencers should be replaced when dirty or clogged to provide optimum performance.
A spare silencer is included with the purchase of a new polisher.
Maintenance and Usage Tip:
Operating the tool at a pressure that exceeds the recommended operating
specifi cations or without the silencer may result in premature failure of the
tool.
The silencer, Part # 658-52, should be replaced when it no longer allows air
to fl ow freely. This is indicated by a dark, shiny appearance.
WARNING!
Tools sent in for repair, where the silencer is removed or blown out,
are not covered under our Limited Warranty!
