CONTACT TRIP MODEL with ANTI-DOUBLE
FIRE MECHANISM
The anti-double fire mechanism (US patent
5597106, UK patent 2286790) is installed on this
tool.
The common operating procedure on "Contact
Trip" tools is for the operator to contact the work
to actuate the trip mechanism while keeping the
trigger pulled, thus driving a fastener each time
the work is contacted. This will allow rapid fas-
tener placement on many jobs, such as sheath-
ing, decking and pallet assembly. All pneumatic
tools are subject to recoil when driving fasteners.
The tool may bounce, releasing the trip, and if
unintentionally allowed to re-contact the work
surface with the trigger still actuated (finger still
holding trigger pulled) an unwanted second fas-
tener will be driven.
CONTACT FIRE OPERATION
For contact fire operation, hold the Trigger and
depress the Contact Arm against the work sur-
face.
PROCEDURE
1
Hold the Trigger.
2
Depress the Contact Arm.
SINGLE FIRE OPERATION (ANTI-DOUBLE
FIRE MECHANISM)
For single fire operation, depress the Contact
Arm against the work surface and pull the Trig-
ger. Tool cannot fire a second nail until the Trig-
ger is released and tool can cycle.
PROCEDURE
1
Depress the Contact Arm.
2
Pull the Trigger.
