DRIVING FASTENERS

CONTACT TRIP MODEL w/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.

e

Nail loading:
Place a coil of nails over the post in the magazine. Uncoil enough nails to reach the 
feed pawl, and place the second nail between the teeth on the feed pawl. The nail 
heads fit in slot on nose.

r

Swing cover closed.

t

Close the door.
Check that latch engages. (If it does not engage, check that the nail heads are in the 
slot on the nose).

TEST OPERATION

q

Adjust the air pressure at 85 p.s.i. (6 bar) and connect the air supply.

w

Without touching the trigger, depress the contact arm against the work-piece.
Pull the trigger. (The tool must fire the fastener.)

e

With the tool off the work-piece, pull the trigger.
The depress the contact arm against the work-piece.
(The tool must fire the fastener.)

r

Adjust the air pressure as much as the lowest possible according to the diameters and length of 
fastener and the hardness of work-piece.
