Operation - DeWalt D51276-XE Instruction Manual

TO INSTALL AN AIR FITTING
1. Wrap the male end of the fitting with sealing 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.

OPERATION

Preparing the Tool
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.
NOTE: These nailers are designed to be used without oil. If preferred,
5–7 drops of oil may be used on o-rings, rubber parts and can be applied
to the air fittings.
CAUTION: To reduce the risk of damage to the tool, only use D
Pneumatic Tool Oil or a non-detergent S.A.E. 20 weight oil. Oil with
additives or detergent will damage tool parts.
1. Before you use the nailer, be sure that the compressor tanks have been
properly drained.
2. Wear proper eye, hearing and respiratory protection.
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. 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 ).

6. Connect air hose.
7. 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.
FIG. 4
Using the Lock-off (Fig. 4)
WARNING: To reduce the risk of injury, ALWAYS wear proper eye [ANSI
Z87.1 (CAN/CSA Z94.3)] and hearing protection [ANSI S12.6 (S3.19)]
when operating this tool.
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 or personal injury
may result.
Each D WALT nailer is equipped with a trigger lock-off switch (F) which
E
when rotated to the right, prevents the tool from actuating. When the switch
is centered, the tool will be fully
operational. The trigger should always be locked off whenever any
adjustments are made or when tool is not in use.
Loading the Tool
WARNING: Keep the tool pointed away from yourself and others. Serious
personal injury may result.
WARNING: Never load nails with the contact trip or trigger activated.
Personal injury may result.
WALT
E
The D WALT finish nailers are equipped with dual load magazines. The
E
fasteners can be loaded using one of two methods:
LOAD AND LOCK METHOD (FIG. 5)
1. Lock off trigger.
2. Insert fasteners into the rear of the magazine (G).
3. Pull pusher (H) back until the nail follower falls behind the nails.
LOCK AND LOAD METHOD
1. Lock off trigger.
2. Pull pusher back until it locks in the the pusher latch.
3. Insert fasteners into the rear of the magazine.
4. Press the pusher button (N) to release and allow the nail follower (H) to
fall behind the nails.
Actuating Tool
WARNING: To reduce the risk of injury, 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.
F
SEQUENTIAL ACTION TRIGGER -
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 -
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.
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.

Adjusting Depth (Fig. 6)
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.
The depth that the fastener is driven can be adjusted using the depth
adjustment next to the trigger of the tool.
1. To drive the nail shallower, rotate the depth setting wheel (I) to the
right (Fig. 6A).
2. To drive a nail deeper, rotate the depth setting wheel (I) to the left
(Fig. 6B).

Clearing a Jammed Nail (Fig. 7)
WARNING: Lock off trigger, disconnect air line from tool and remove
fasteners from magazine before making adjustments or personal injury
may result.
If a nail becomes jammed in the nosepiece, keep the tool pointed away
from you and follow these instructions to clear:
1. Lock off trigger.
2. Disconnect air supply from tool and lock trigger.
