The work surface can become
damaged by excessive lubrication.
Proper lubrication is the owner's
responsibility. Failure to lubricate the
tool properly will dramatically shorten
the life of the tool and void your
warranty.

Avoid using solvents when cleaning plastic
parts. Most plastics are susceptible to damage
from various types of commercial solvents and
may be damaged by their use. Use clean cloths
to remove dirt, dust , oil, grease, etc.
CLEANING
Do not at any time let brake fluids,
gasoline, petroleum-based products,
penetration oils, ect., come in contact
with plastic parts. Chemicals can
damage, weaken or destroy plastic
which may result in serious personal
injury.
WARNING:
!
COLD WEATHER OPERATION
For cold weather operation, near and below
freezing, the moisture in the air line may freeze
and prevent tool operation. We recommend the
use of air tool lubricant or permanent antifreeze
(ethylene glycol) as a cold weather lubricant.
Do not store tools in a cold weather
environment to prevent frost or ice
formation on the tool's operating
valves and mechanisms that could
cause tool failure.
CAUTION:
The air compressor must be able to maintain
a minimum of 70 psi when the tool is being
used. An inadequate air supply can cause a
loss of power and inconsistent driving.
An oiler can be used to provide oil circulation
through the tool. A filter can be used to
remove liquid and solid impurities which can
rust or gum up internal parts of the tool.
Always use air supply hoses with a minimum
working pressure rating equal to or greater
than the pressure from the power source if a
regulator fails, or 150 psi, whichever is
greater. Use 3/8 in. air hose for runs up to 50
ft. and use a 3/8 in. quick coupler on the air
hose.
Use a pressure regulator on the compressor,
with an operating pressure of 0-125 psi. A
pressure regulator is required to control the
operating pressure of the tool between 70
psi and 110 psi.

The air compressor must be able to
maintain a minimum of 70 psi when the
tool is being used. An inadequate air
supply can cause a loss of power and
inconsistent driving.
CAUTION:
Do not connect with an air compressor
which can potentially exceed 200 psi.
As tool may burst, possibly causing
injury.
