needed.
4. Clean the cylinder head fins for prop-
er cooling.

water has been released.

Like all power tools, there is danger
associated with operating this
equipment. Accidents are frequently
caused by lack of familiarity or fail-
ure to pay attention. Use this
machine with respect and caution to
lessen the possibility of operator
injury. If normal safety precautions
are overlooked or ignored, serious
personal injury many occur.
Water will condense in the air com-
pressor tank. Water left in the tank
can cause the tank to weaken and
corrode, increasing the risk of tank
rupture
