CHANGEOVER LEVER
This tool has a changeover lever mechanism, which allows opti-
mum (drivability, speed) screwing work depending on the condi-
tion of the driven-side base material.
NOTICE:
•
It is recommended to set the changeover lever to an appropri-
ate position suitable for the condition of the driven-side base
material.
CHANGEOVER LEVER POSITION
∗
1 : ptimum
∗
2 : rivable
∗
3 : Cannot drive
NOTICE:
•
For the condition of the metal base material and 2 pcs. of dry-
wall boards, you cannot drive at the changeover lever position
of “W”.
•
The changeover lever should be properly operated and set to
the position of “W" or “M" until it clicks.
MODEL IDENTIFICATION
CONTACT TRIP
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 al-
lowed to recontact the work surface with the trigger still actuated
(finger still holding trigger pulled) an unwanted second fastener
will be driven.

RED TRIGGER.
CONTACT FIRE OPERATION (CONTACT TRIP)
For contact fire operation, hold the Trigger and depress the Con-
tact Arm against the work surface.
PROCEDURE
1
Hold the Trigger.
2
Depress the Contact Arm.
SINGLE FIRE OPERATION (ANTI-DOUBLE FIRE MECHA-
NISM)
For single fire operation, depress the Contact Arm against the
work surface and pull the Trigger.
Tool cannot fire a second nail until the Trigger is released and
tool can cycle.
PROCEDURE
1
Depress the Contact Arm.
2
Pull the Trigger.
SEQUENTIAL TRIP (Optional kit)
The Sequential Trip requires the operator to hold the tool against
the work before pulling the Trigger. This makes accurate fastener
placement easier, for instance on framing, toe nailing and crating
applications. The Sequential Trip allows exact fastener location
without the possibility of driving a second fastener on recoil, as
described under "Contact Trip".
The Sequential Trip Tool has a positive safety advantage be-
cause it will not accidentally drive a fastener if the tool is contact-
ed against the work-or anything else-while the operator is holding
the Trigger pulled.
