Slip the air socket of the air hose onto the air fitting on
the nailer. Be sure that the air socket locks firmly into
position when installed onto the air fitting.
A hose coupling must be installed on or near the tool in
such a way that the pressure reservoir will discharge at
the time the air supply coupling is disconnected.
Changing the trigger for contact
actuation mode
CAUTION:
Always disconnect the air hose
and unload the tool with nails before replacing
the trigger.
CAUTION:
After the trigger replacement,
always check that the tool operates properly
before actual work. Do not load the tool with any
nails before checking the function to avoid unex-
pected nailing.
The trigger for single sequential actuation mode is
factory-installed. To change the nailing mode to contact
actuation, replace the trigger part with the one for con-
tact actuation.
