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 fastener placement on many jobs, such as sheathing, 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 fastener will be driven.
CONTACT FIRE OPERATION
For contact fire operation, hold the Trigger and depress the Contact Arm against the work surface.
