Makita AF631 Instruction Manual page 4

There may be local regulations concerning noise
which must be complied with by keeping noise levels
within prescribed limits. In certain cases, shutters
should be used to contain noise.
Do not tamper with the tool or attempt to use
it
for
other than nailing. Do not play with the contact
element; it prevents accidental discharge, so it must
be kept on and not removed. Securing the trigger
in the ON position is also very dangerous. Never
attempt to fasten the trigger.
Operate the tool within the specified air pressure of
4.0
-
8.5 kgf/cm*G (60
-
120 PSIG) for safety
and longer tool life. Do not exceed the recommended
max. operating pressure of 8.5 kgf/cm'G (120
PSIG). The tool should not be connected to a source
whose pressure potentially exceeds 14.0 kgf /cm'G
(200 PSIG).
Never use the tool with other than compressed air.
If high-pressure gas (carbon dioxide, oxygen, nitro-
gen, hydrogen, propane, acetylene, etc.) is used as
a power source for this tool, the tool will explode
and cause serious injury.
