2. Remove all nails from the magazine
3. Check if the contact trip
4. Reload the nails to the magazine.
5. Insert battery pack.

WARNING: Do not use the tool if the contact trip or
nail pusher cannot move freely.
NOTICE: 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.
Running in the Tool
Please note that this tool requires a run‑in period before it
operates with full power due to parts which need to mesh or
wear in together. It may be that the tool does not drive long
nails flush consistently during this period.
Actuating The Tool (Fig. A)
The tool can be operated using one of two modes:
Sequential Action Mode
The sequential action mode is used for intermittent nailing when
very careful and accurate placement is desired. It also offers the
maximum delivery of power for driving the longest nails.
1. Using the mode selector switch
action mode ( or .
2. Release the trigger safety lock‑off
3. Push the contact trip
4. Pull the trigger switch
5. Release the trigger and raise the nailer from the work surface.
6. Repeat steps 3–5 to actuate the next nail.
Contact Trip Mode
Contact trip mode (also known as bump mode) is used for
rapid nailing on flat, stationary surfaces and typically most
effective for application driving shorter nails.

2. Release the trigger safety lock‑off
3. To drive a single nail, operate the tool as described for
sequential action:
a. Push the contact trip
b. Pull the trigger switch
trigger pull with the contact trip pushed against the
work surface will drive one nail.
4. To drive several nails, depress and hold the trigger
switch 1 , and then push the contact trip
against the work surface.

WARNING: Do not keep the trigger depressed when
the tool is not in use. Keep the trigger safety lock‑off
in the locked position to prevent accidental actuation
when the tool is not in use.
5. When changing between sequential and bump modes,
it may be necessary to adjust the driving depth. Refer to
Adjusting the Driving Depth for instructions.
Using the Trigger Lock‑Off (Fig. A)
Each D WALT nailer is equipped with a trigger lock‑off
e
which when pushed to the right as shown in Fig. A,
prevents the tool from firing a nail by locking the trigger and
bypassing power to the motor.
When the trigger lock‑off
will be fully operational. The trigger lock‑off
be locked off whenever any adjustments are made or when
tool is not in immediate use.
No‑Mar Tip (Fig. A)
When using this tool on materials that you do not want to
mark, such as wood cladding, use the plastic no‑mar tip
over the contact trip .

nOTE: For maximum depth of drive, especially with long
nails, the no‑mar tip should be removed.
LED Indicator (Fig. A)
Your nailer is equipped with an LED indicator light
you of a jam/stall. Also refer to the Troubleshooting Guide
for further instruction.
Stall Release (Fig. A)
If the nailer is used in rigorous application where all available
energy in the motor is used to drive a fastener, the tool
may stall. The driver blade did not complete the drive cycle
and the jam/stall LED indicator
release lever 6 on the tool and the mechanism will release.
If the driver blade does not automatically return to the home
position, proceed to Clearing a Jammed Nail. If the unit
continues to stall please review the mode selection, material
and fastener length to be sure that it is not too rigorous
an application.
