remove it prior to inserting 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 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 fol-
lowing 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. Lock the pusher in the back position and remove all fasteners from the magazine.
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 lim-
its; 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 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 fol-
lowing procedures and checks before each use of the nailer.
When operating tools at temperatures below freezing, complete preparation procedures out-
lined 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 tem-
perature.
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 contain-
E
ing 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 WALT Pneumatic Tool Oil or winter weight pneumatic oil containing
E
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: 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 actu-
ation.
To operate the tool using the PLACE ACTUATION method:
1. Depress the contact trip against the work surface.
2. Depress the trigger.

2 ).
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 multi-
ple 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 speci-
fications 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
E
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.
Clearing a Jammed Nail (Fig. 7, 8)
If a nail becomes jammed in the nosepiece, follow these instructions to clear:
1. Engage the trigger lock-off lever by pushing it to the right. Disconnect the air supply from
the tool.
2. Remove nails from the magazine.
3. Open the magazine latch (J). The narrow portion of the latch pin (K) will be exposed. Slide
the magazine back, removing the magazine if desired. This will expose the bent nail.
4. Remove the bent nail, using pliers if necessary.
5. If the driver blade is in the down position, insert screwdriver or other rod into nosepiece
and push driver blade up so that it is ready to fire.
6. To reattach the magazine, follow the directions below:
a. Be sure that the magazine latch is open.
b. Insert the latch pin (K) into the the largest opening in the magazine bracket.
c. Align front end of the magazine with nosepiece posts (L) and slide the magazine onto
the tool, guiding the latch pin to the end of the slot. Be sure the magazine is pushed for-
ward, so that the flange on the nose overlaps the magazine.
7. Press the magazine latch (J) back up to its locked position.
8. Reattach air supply.
9. Pull the pusher (H) back.
10. Reinsert nails into the magazine.
11. Release pusher.
NOTE: Should nails continue to jam frequently in nosepiece, have tool serviced by an author-
ized D WALT service center.
E
Depth Setting (Fig. 9)
WARNING: Always disconnect tool from air supply before adjusting depth.
Fastener driving depth can be adjusted using the depth adjustment on the nosepiece 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.
Rafter Hook
