maintenance and usage Tip:

• Do not leave the stone cutter submersed in water. This could expose the inner moving parts to moisture, which will shorten the life of the stone cutter.

• Excessive force or impact to the spindle may result in premature failure of gears and/or bearings, which may not be immediately evident.

To comply with OSHA Occupational Noise Exposure Standard Number

1926.52, this tool is equipped with an internal Silencer System. When the tool is operated correctly at 90 PSI, the sound level emitted should be less than 91.3 dBA. The internal Silencer System is also used to maintain a constant back pressure inside the tool; this helps prevent it from exceeding the recommended 8,500 RPM. The exhaust deflector for this stone cutter also helps to reduce the noise level by venting the exhaust air.
