trained persons. A tool is dangerous
in the hands of untrained users.
Maintain the tool with care. m. Keep
tool clean. A properly maintained tool,
reduces the risk of binding and is
easier to control.
Check for misalignment or bind-n.
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.
Use only accessories that are o.
identied by the manufacturer for

more efcient, but are not required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool perfor-
mance, can be hindered by under-
sized air supply components.

to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
Adjust the air compressor’s output 6.
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,
while checking the air output gauge
to set the right pressure range.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.
To Attach An Air Connector:
1. Attach a 1/4” Connector (not
included) to the Air Plug (83) on the
Nailer.
2. Wrap about 3” of pipe thread seal
tape (not included) onto threads of
the Connector before attaching it to
the Air Plug.
3. Connect the 3/8” air source hose to
the Nailer.
4. Set the air pressure on compressor to
70 to 120 PSI operating pressure. Do
not exceed 120 maximum PSI.
5. Check air connection for leaks. If any
are present, disconnect the Nailer
from air source hose.
Inspect the air connections for leaks. 7.
Repair any leaks found.
If the tool will not be used at this time, 8.
turn off and detach the air supply
and safely discharge any residual air
pressure.
