and safest performance. Follow instructions for lubricating and changing
accessories. Keep handles dry, clean and free of oil or grease. Inspect
moving parts for alignment and binding as well as for breakage and improper
mounting.

adjustments, or change discs without making sure the air valve is in the off

SPECIAL FEATURE
The Alpha®Air Polisher was designed with human engineering for operator comfort.
It comes equipped with a silencer which reduces the level of noise as well as
guiding the cold exhaust air away from an operator during the polishing process.
This feature also eliminates excess lubricant dripping on the work piece. Portions
of the body design are made with synthetic materials and covered with rubber to
prevent fatigue and coldness to hands.
