provides the maximum delivery of power for driving the
longeststaples.
To operate the stapler in sequential actuation mode:
1. Slide the selector switch
7
to expose the singlestaple
icon .
2. Fully depress nosepiece against the work surface (motor
will start).
3. Pull trigger (staple will drive into work surface).
4. Releasetrigger.
5. Lift nosepiece off worksurface.
6. Repeat steps 2 through 4 for nextapplication.
NOTICE: The contact trip needs to be depressed followed by
a trigger pull for each staple followed by a release of both the
contact trip and trigger after eachstaple.
Bump Action (Fig.E)
Bump action is intended for rapid stapling on flat, stationary
surfaces and typically most effective for applications that
require driving shorterstaples.
When the tool is set in the bump actuation mode, two
methods of tool operation are available: place actuation and
bumpactuation.
Slide the selector switch
7
to expose the triple
staple icon .
To operate the tool using the place actuation method:

WARNING: A staple will be driven each time the trigger is
depressed as long as the contact trip remainsdepressed.
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 drive a staple every
time the contact trip is depressed. This allows the user to
drive multiple staples insequence.

WARNING: Do not keep trigger depressed when tool
is not in use. Keep the trigger lock‑off in the locked position
when the tool is not inuse.

WARNING: When the tool’s motor is running, pulling the
trigger or depressing the contact trip will cause a staple to
bedriven.
Preparing the Tool

WARNING: NEVER spray or in any other way apply
lubricants or cleaning solvents inside the tool. This can
seriously affect the life and performance of thetool.
NOTE: The battery pack is not fully charged out of the carton.
1. Read all power tool and stapler safety warnings in
thismanual.
2. Wear eye and earprotection.
3. Ensure magazine is empty of allfasteners.
4. Check for smooth and proper operation of contact trip
and pusher assemblies. Do not use tool if either assembly
is not functioning properly. NEVER use a tool that has the
contact trip restrained in the actuatedposition.
5. Keep tool pointed away from yourself andothers.
6. Insert fully charged batterypack.
Using the Trigger Lock-off (Fig. F)

WARNING: To reduce the risk of serious personal injury,
do not keep trigger depressed when tool is not in use. Keep
the trigger lock‑off switch LOCKED (Fig.F) when the tool is
not inuse.

WARNING: To reduce the risk of serious personal injury,
lock off trigger, disconnect battery pack from tool and remove
staples from magazine before makingadjustments.
Each DeWALT stapler is equipped with a trigger lock-off
2
which when pushed to the right as shown in FigureF,
prevents the tool from firing a staple by locking the trigger
and bypassing power to themotor.
When the trigger lock-off is pressed to the left, the tool will
be fully operational. The trigger lock-off should always be
locked off whenever any adjustments are made or when
tool is not in immediateuse.
NOTICE: Do not store tool with battery pack installed. To
prevent damage to the pack and to ensure best battery
life, store battery packs out of the tool or charger in a cool,
drylocation.

Dryfire Lock Out Feature (Fig. A)
Tool is equipped with a dryfire lock out feature to prevent
tool from cycling when there are no fasteners loaded. When
no fasteners are visible in the fastener window
16
, the tool
is running low on fasteners. If this happens, the tool will
be locked out and will not actuate until more staples are
loaded. (Refer to Loading the Tool.)
Adjusting Depth (Fig. H)
The depth that the fastener is driven can be adjusted using
the depth adjustment wheel
3
on the side of thetool.

WARNING: To reduce risk of serious injury from
accidental actuation when attempting to adjust depth,
ALWAYS:
• Remove batterypack.
• Engage trigger lock‑off.
• Avoid contact with trigger duringadjustments.
1. To drive the staple shallower , rotate the depth
adjustment wheel
3
away from the nose of thestapler.
2. To sink a staple deeper , rotate the depth adjustment
wheel
