with a sequential action trigger. However, a bump action trigger kit is included and attached 
to the tool. For a replacement trigger contact your authorized service center or call

WALT.

The gray trigger with 

 imprinted on the side, (Cat.# D510002 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.# D510004 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.

The D

E

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" 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 inserting the fitting.

the beginning of this manual. 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

E

WALT Pneumatic Tool Oil or winter weight pneumatic oil containing 

ethylene glycol in the 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

E

WALT Pneumatic Tool Oil or winter weight pneumatic oil containing 

ethylene glycol in the end cap at least twice a day or after 4 hours of use.

Tool should operate normally. However, keep tool out of direct sunlight as excessive heat can 
damage bumpers, o-rings and other rubber parts.

magazine before making adjustments. Serious personal injury may result.
Each D

WALT nailer is equipped with a trigger lock-off switch (F). To engage the lock-off 

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.

[ANSI S12.6 (S3.19)] 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. 

 (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.

 (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.

  1. Pull the nail pusher (H) back until it latches.
 2. Drop appropriate collated nail sticks into loading slot on top of mag 

azine. 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.

To protect from internal damage, the D

E

WALT Framing Nailers are equipped with a dry fire 

lockout, which prevents the 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.

Fastener driving depth can be adjusted using the depth adjustment on the nosepiece of 
the tool.
  1. To adjust depth setting, push button (M), slide contact trip (E) down then push button (N) 

in to set contact trip.    

  2. To sink a nail deeper, push button (M), slide contact trip (E) upward to the extent desired, 

then push button (N) in to set contact trip.

WHY 

 Prevents failure of o-rings

HOW 

Insert drops into air fitting on end cap of tool

ACTION  Drain compressor tanks and hoses daily
WHY 

 Prevents accumulation of moisture in compressor and nailer

HOW 

 Open petcocks or other drain valves on compressor tanks. Allow any accumulated 
water to drain from hoses

Clean magazine, pusher, and contact trip mechanism

WHY 

 Permits smooth operation, reduces wear, and prevents jams

HOW 

 Blow clean with compressed air. The use of oils or solvents is not recommended as 
they tend to attract debris

Before each use, check to ensure all screws, nuts and fasteners are tight and 
undamaged

WHY 

 Prevents jams, leaks and premature failure of tool parts

HOW 

 Tighten loose screws or other fasteners using the appropriate hex wrench or 
screwdriver
