direct sunlight to avoid damage to the bumpers,
o-rings and other rubber parts.
Rafter Hook (fi g. 1)
The D WALT framing nailers include an integrated
E
rafter hook and can be rotated to either side of the
tool and can be folded out of the way when not in
use.
If the hook is not desired at all, it can be removed
from the tool.
Using the Lock-off (fi g. 3)
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.
Serious personal injury may result.
WARNING: Lock-off trigger, disconnect
air line from tool and remove
fasteners from canister before making
adjustments. Serious personal injury
may result.
Each D WALT nailer is equipped with a trigger
E
lock-off switch (a) which when rotated to the right,
prevents the tool from actuating. When the switch
is centered, the tool will be fully operational. The
trigger should always be locked off whenever any
adjustments are made or when tool is not in use.
Actuating the Tool
WARNING: To reduce the risk of
seriouse personal injury, ALWAYS wear
proper eye and hearing protection 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 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 - (BLACK)
The bump action trigger's intended use is for rapid
nailing on flat, stationary surfaces.
