AIR Valve Lever

The valve lever controls the ﬂow 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 ﬂow 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 speciﬁcations 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 ﬂow 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!
