ASSEMBLY
CAUTION: Disconnect air line from tool and remove fasteners from magazine before making adjustments.
Trigger
In accordance with the ANSI Standard SNT-101-2002, the D
ger. A bump action trigger kit is available for purchase from D
contact your authorized service center or call 1-800-4-D
The gray trigger with
imprinted on the side, (Cat.# D510023 kit) is the single sequential action trigger and causes
the tool to operate in this mode.
The black trigger with
imprinted on the side, (Cat.# D510020 kit) is the bump action trigger and permits the tool
to be actuated in this manner.
For defining the use of the sequential action trigger and bump action trigger, see the Actuating Tool section of this
manual.

TRIGGER REMOVAL (FIG. 1)
1. Remove rubber grommet (A) from the end of the dowel pin (B).
2. Remove dowel pin.
3. Remove trigger assembly from trigger cavity under the handle of the tool housing.
TRIGGER INSTALLATION (FIG. 2)
1. Select either the sequential or bump action trigger to be installed on the tool.
2. Insert the trigger assembly into trigger cavity making sure that the trigger spring (C) is placed around trigger valve
stem (D).
3. Ensure that the contact trip guide (E) is pushed fully upward so that it is flush with the tool housing and aligned
with the housing holes.
4. Insert the dowel pin (B) through the tool frame and trigger assembly as shown.
5. Push the rubber grommet (A) onto the end of the dowel rod.
Air Fitting
The D
WALT framing nailers have a standard 3/8" pipe thread for the air fitting. The tool is assembled with a 3/8" to 1/4"
E
adapter installed in the end cap.
TO INSTALL AN AIR FITTING
1. Wrap the male end of the fitting with teflon tape prior to assembly to eliminate air leaks.
2. To install a 1/4" fitting: screw the fitting into the 3/8" to 1/4" adapter in the end cap of the tool and tighten firmly.
3. To install a 3/8" fitting: screw it directly into the end cap. If an adapter is in the end cap, remove it prior to insert-
ing the fitting.
OPERATION
Preparing the Tool (Fig. 3, 4)
WARNING: Read the section titled "Important Safety Instructions for Pneumatic Tools" at the beginning of this manu-
al. Always wear eye and ear protection when operating this tool. Keep the nailer pointed away from yourself and others.
For safe operation, complete the following procedures and checks before each use of the nailer.
1. Before you use the framing nailer, be sure that the compressor tanks have been properly drained.
2. Lubricate the tool following these directions:
a. Use D
WALT Pneumatic Tool Oil or a non-detergent S.A.E. 20 weight oil. DO NOT use
E
detergent oil or additives as they will damage O-rings and rubber parts.
b. Use a Filter-Regulator-Lubricator in the air line between the compressor and the tool
when possible.
c. If a lubricator is not available, add 5 to 10 drops of oil in the air fitting a least twice a
day or every 4 hours of use.
3. Be sure that there are no fasteners in the magazine. Lock the pusher in the back position.
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 up position.
5. Check air supply. Be sure that air pressure does not exceed recommended operating
limits; 70 to 120 psi, (4.9 to 8.3 bar, 5 to 8.5 kg/cm
6. Connect air hose.
7. Check for audible leaks around valves and gaskets. Never use a tool that leaks or has
damaged parts.
Cold Weather Operation
WARNING: Read the section titled "Important Safety Instructions for Pneumatic Tools" at the beginning of this manu-
al. Always wear eye and ear protection when operating this tool. Keep the nailer pointed away from yourself and others.
For safe operation, complete the following procedures and checks before each use of the nailer.
When operating tools at temperatures below freezing, complete preparation procedures outlined above and follow the
directions below.
1. Make sure compressor tanks have been properly drained prior to use. Always drain the compressor tanks at least
once daily while using the nailer. This is especially important in cold weather because any moisture in the air in the
tanks will condense in the cold temperature.
2. Keep the tool as warm as possible prior to use.
3. Put 5 to 10 drops of D
WALT Pneumatic Tool Oil or winter weight pneumatic oil containing ethylene glycol in the
E
end cap.
4. Lower air pressure to 80 psi or less.
5. Actuate the tool 5 or 6 times into scrap lumber to lubricate O-rings.
6. Turn pressure up to operating level (not to exceed 120 psi) and use tool as normal.
7. Re-lubricate with D
WALT Pneumatic Tool Oil or winter weight pneumatic oil containing ethylene glycol in the end cap
E
at least twice a day or after 4 hours of use.
Hot Weather Operation
Tool should operate normally. However, keep tool out of direct sunlight as excessive heat can damage bumpers, O-rings
and other rubber parts.
Using the Lock-off (Fig. 5)
WARNING: Always wear eye and ear protection when making adjustments to
the tool.
Each D
WALT nailer is equipped with a trigger lock-off switch (F). To engage the lock-off
E
switch, rotate it to the right. To disengage the lock-off switch, center it. The trigger should
always be locked off whenever any adjustments are made or when tool is not in use.
Actuating the Tool
WARNING: Always wear eye and ear protection when operating 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 -
(GRAY)
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.
CAUTION: 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.
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.
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.
Loading the Tool (Fig. 6)
CAUTION: Keep tool pointed in a safe direction when loading nails.
CAUTION: Never load nails with the contact trip or trigger activated.
1. Pull the nail pusher (H) back until it latches.
2. Drop appropriate collated nail sticks into loading slot on top of magazine. See tool
specifications to determine appropriate nail sizes and angles.
3. Pull the nail pusher a second time to release latch, and carefully allow the pusher to
slide forward until it makes contact with the nails.
Dry Fire Lockout
To protect from internal damage, the D
WALT Framing Nailers are equipped with a dry fire lockout, which prevents the
E
tools from actuating when the magazine is nearly empty. When approximately 4 or 5 nails remain in the magazine and
the tool ceases to operate, follow the loading instructions to reload sticks of collated nails.
Depth Setting (Fig. 7)
WARNING: Always disconnect tool from air supply before adjusting depth.
Fastener driving depth can be adjusted using the depth adjustment on the nose piece of
the tool.
1. To drive the nail less deeply, press the adjustment button (M) and slide the contact
trip (E) down. Release the adjustment button.
2. To sink a nail farther, press the adjustment button (M) and slide the contact trip (E)
upward to the extent desired. Release the adjustment button.
