WARNING
Always use a coupling that discharges all the

hose coupling is disconnected. Using a coupling that
does not discharge the compressed air could cause
unintended operation and serious personal injury.
WARNING
Do not climb rigging or scaffolding while carrying a tool
that is connected to an air hose. Doing so could result
in serious personal injury.
Connect the tool to the air supply with a 1/4 in. female
quick connector. For maximum tool performance, a 3/8 in.

WARNING
The tool’s driving mechanism may cycle when the tool

tool to a pressurized air supply before loading fasteners
to prevent injury from unintended cycling. Always make
sure the tool’s magazine is empty at the beginning of
each work session, before connecting to an air supply.
1. Connect the tool to the air supply.
2. With the safety yoke of the tool pointed away from you,
feed a strip of fasteners into the magazine. Be sure
the fasteners are pointed downward and at the angle
shown.
3. Slide the pusher all the way to the rear of the magazine.
WARNING
Keep the tool pointed away from yourself and others
when loading fasteners. Failure to do so could result in
possible serious personal injury.
4. Release the pusher and allow it to push the fasteners
to the driving mechanism. The pusher will stop when it
rests against the end of the fastener strip.
NOTE:
Do not allow the pusher to snap back into place.
WARNING
Use only the fasteners recommended for use with this
tool. The use of any other fasteners can result in tool
malfunction, leading to serious injuries.
WARNING
Never load fasteners with the safety yoke or trigger
activated. Doing so could result in possible serious
personal injury.
WARNING
Do not use fasteners with shank diameter smaller than
2.87 mm. Doing so may cause fasteners to exit the
tool prematurely through the guide track. Do not use
hardened fasteners with pneumatic tools. This could
lead to excessive wear of the guide body and allow
fasteners to exit the back of the guide body, leading to
serious personal injury.
DRIVING A FASTENER
6HH¿JXUH
WARNING
Check the safety yoke before use. If it is deformed or
cannot telescope, do not use the tool until it is replaced.
Operate with a deformed safety yoke could result in
serious personal injury.
WARNING
Never wedge or hold back the safety yoke mechanism
during operation of the tool. Doing so could result in
possible serious injury.
Avoid triggering the fastener driving tool if the magazine
is empty.
Any defective or improperly functioning fastener driving tool
must immediately be disconnected from the compressed
air supply and passed to a specialist for inspection.
In the event of longer breaks in work or at the end of the
working shift, disconnect the tool from the compressed air
supply and it is recommended to empty the magazine.
The compressed air connectors of the fastener driving tool
and the hoses should be protected against contamination,
the ingress of coarse dust chips, sand, etc, will result in
leaks and damage to the fastener driving tool and the
couplings.
Single sequential actuation mode
The tool employs single sequential actuation mode.
1. Connect the tool to the air supply.
