Actuating Tool
WARNING: 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 -
The sequential action trigger's intended use is for intermittent fastening where very careful and
accurate placement is desired.
To operate the stapler in sequential action mode:
1. Depress the contact trip firmly against the work surface.
2. Depress the trigger.
CAUTION: A fastener will fire each time the trigger is depressed as long as the contact trip
remains depressed.
BUMP ACTION TRIGGER - (BLACK)
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. Depress the contact trip against the work surface.
2. Depress the trigger.
To operate the tool using the BUMP ACTUATION method:
1. Depress the trigger.
2. Push the contact trip against the work surface. As long as the trigger is depressed, the tool
will fire a fastener every time the contact trip is depressed. This allows the user to drive
multiple fasteners in sequence.
CAUTION: Do not keep trigger depressed when tool is not in use. Keep the lock-off switch
rotated to the right (OFF) when the tool is not in use.
Adjusting Depth (Fig. 6, 7)
The depth that the fastener is driven can be adjusted using the depth adjustment next to the
trigger of the tool.
WARNING: To reduce risk of serious injury from accidental actuation when
attempting to adjust depth, ALWAYS:
• Lock off trigger.
• Disconnect air supply.
• Avoid contact with trigger during adjustments.
1. To drive the fastener shallower, rotate the depth setting wheel (Fig. 6, G or Fig. 7, H) to
the right.
2. To drive a fastener deeper, rotate the depth setting wheel (Fig. 6, H or Fig. 7, H) to the
left.
