1.CONTACT TRIP:

The common operation procedure on “Contact Trip” tools is for the operator to contact the work surface to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work surface is contacted. This will allow rapid fastener placement on many jobs. 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 the trigger pulled) an unwanted second fastener will be driven.

2.SEQUENTIAL TRIP:

The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes accurate fastener placement easier. The Sequential Trip allows exact fastener location without the possibility if driving a second fastener on recoil as described under “Contact Trip”. The Sequential Trip Tool has a positive advantage because it will not accidentally drive a fastener if the tool is contacted against the work surface - or anything else - while the operator is holding the trigger pulled.

SELECTING THE TRIP MODE:

To ensure safety, the user must lock the trigger (as described on page 8) before changing the trigger system. To change the trip mode, rotate the mode switch toward the body of the tool. The mode switch will lock automatically when the indicating arrow is pointing down to the 3 nail icon stamped into the tool frame (Contact Trip Mode) or to a single nail icon stamped in the tool frame( Sequential Trip Mode). Unlock the trigger to resume tool operation.

DIAL-A-DEPTH®FASTENER CONTROL ADJUSTMENT

The DIAL-A-DEPTH®Fastener control adjustment feature provides close control of the fastener drive depth: from flush with the work surface to shallow or deep countersink. First set the air pressure for consistent drive in the specific work as described on page 6, then use the DIAL-A-DEPTH®fastener control adjustment to give the desired depth of drive.
