AVOID PROLONGED EXPOSURE TO VIBRATION
Pneumatic tools can vibrate during use. Prolonged exposure
to vibration or very repetitive hand and arm movements, can
cause injury. Stop using any tool if discomfort, tingling feeling
or pain occurs. You should consult your physician before
resuming use of the tool.
90 PSIG MAXIMUM
Designed to operate at an air pressure of 90 pounds per square
inch gauge pressure (90 PSIG) maximum, at the tool. Use of
higher air pressure can, and may cause injury. Also use of
higher air pressure places the internal components under loads
and stresses they were not designed for, causing premature
tool failure.
NOTE: The air supply should be clean and dry, preferably
lubricated. For best results drain the moisture from your
compressor daily.
