LOCK-OUT MECHANISM
This tool is equipped with a Lock-Out mechanism which engages
automatically to prevent the tool from actuating without driving a fastener.
The tool will not actuate when the Lock-Out is engaged, as shown.
TRIP OPERATION MODE
Always disconnect air supply before making adjustments as accidental actuation may occur,
possibly causing injury.
Always verify and be aware of tool operating mode by inspecting the trigger before
connecting to an air supply and / or using the tool.
This tool has two operating modes:
1. Contact Trip Operation
For better drive quality in light gauge steel framing, the use of a sequential trigger is highly recommended.
1. CONTACT TRIP:
NEVER use the utility hook with the tool in contact mode, ALWAYS switch the tools
operation mode back to sequential before using the utility hook option.
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.
