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.
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:
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 magazine before making adjustments. Serious personal
injury may result.

FIG. 5
Each D
E
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.
Actuating the Tool
WARNING:
Always wear proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and
hearing protection [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.
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 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.
Dry Fire Lockout
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.

Depth Setting (Fig. 7)
WARNING: To reduce risk of serious injury from accidental actuation
when attempting to adjust depth, ALWAYS:
• Lock OFF trigger.
• Disconnect air supply.
• Avoid contact with trigger during adjustments.
Fastener driving depth can be adjusted using the depth adjustment on the
nosepiece of the tool.
OPERATION
Preparing the Tool (Fig. 3, 4)
WARNING:
Read the section titled
Important Safety Instructions for
Pneumatic Tools
at 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.
FIG. 3
FIG. 4
1. Before you use the nailer, be sure that the compressor tanks have been
properly drained.
2. Lubricate the tool following these directions:
a. Use D
E
WALT pneumatic tool oil or a non-detergent S.A.E.
20 weight oil.
DO NOT
use 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. Wear proper eye, hearing and respiratory protection.
4. Lock the pusher in the back position and remove all fasteners from the
magazine.
5. 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.
6. Check air supply. Ensure 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
2
).
7. Connect air hose.
8. Check for audible leaks around valves and gaskets. Never use a tool
that leaks or has damaged parts.
WARNING:
To reduce the risk of personal injury, disconnect tool from air
supply before performing maintenance, clearing a jammed fastener, leaving
work area, moving tool to another location or handing the tool to another
person.
