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 nailing 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. Depress the trigger.
WARNING: A nail will fire each time the trigger is depressed as long as the contact trip
remains depressed.
BUMP ACTION TRIGGER -
The bump action trigger's intended use is for rapid nailing 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 nail every time the contact trip is depressed. This allows the user to drive
multiple nails in sequence.
WARNING: 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. 3, 4)
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.
The depth that the fastener is driven can be adjusted using the depth adjustment next to the
trigger of the tool.
1. To drive the nail shallower, rotate the depth setting wheel (K) to the right (Fig. 3).
2. To drive a nail deeper, rotate the depth setting wheel (K) to the left (Fig. 4).
