Actuating Tool


WARNING: To reduce the risk of injury, Always wear
proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and hearing
protection [ANSI S12.6 (S3.19)] when operating
this tool.
The tool can be actuated using one of two modes:
single sequential action trigger mode and bump action
trigger mode. The trigger installed on the tool as described
in the Trigger section of this manual determines the mode
of operation.
Sequential Action Trigger -
Trigger (Fig. A)
The sequential action trigger's intended use is for
intermittent fastening where very careful and accurate
placement is desired.
To Operate the nailer in sequential Action Mode
1. Depress the contact trip firmly against the work surface.
2. Pull the trigger.

WARNING: A fastener will be driven each time the
trigger is pulled as long as the contact trip remains
depressed which could result in accidental driving.
Bump Action Trigger -
(Fig. A)
The bump action trigger's intended use is for rapid fastening
on flat, stationary surfaces.
Using the bump action trigger, two methods are available:
place actuation and bump actuation.
To Operate the Tool Using the Place Actuation Method
1. Push the contact trip against the work surface.
2. Pull the trigger.
3. Release the trigger and allow the tool to recoil off
the workpiece.
To Operate the Tool Using the Bump Actuation Method
1. Pull the trigger.
2. Push the contact trip against the work surface. As long
as the trigger is pulled, the tool will drive a fastener every
time the contact trip is depressed. This allows the user to
drive multiple fasteners in sequence.
