Instructions for use
Always observe the safety instructions
and applicable regulations.
Preparing the tool (fig. C)
• Drain all condensation from the air compressor
tanks and hoses.
• Lubricate the tool. See "Maintenance".
• Remove all nails from the magazine.
• Lock the nail pusher (11) in the back position.
• Check if the contact trip (3) and nail pusher (11)
can move freely.
Do not use the tool if the contact trip or
nail pusher cannot move freely.
• Check that the pressure of the air supply is below
the maximum recommended operating pressure.
• Connect the air hose to the fitting on the tool.
• Check for audible leaks around valves and gaskets.
Never use a tool that leaks or has
damaged parts.
Cold weather operation
When operating tools at temperatures below freezing:
• Keep the tool as warm as possible before use.
• Disconnect the airline from the tool.
• Put 5-10 drops of D WALT pneumatic tool oil (or
E
winter-weight pneumatic oil containing ethylene
glycol) into the air inlet.
• Set the air pressure to a maximum of 5.5 bar.
• Connect the air hose to the fitting on the tool.
• Load nails into the magazine as described below.
• Actuate the tool 5 or 6 times into scrap lumber to
lubricate the o-rings.
• Increase the air pressure to the normal operating
level.
• Use the tool in the normal manner.
Hot weather operation
The tool should operate normally. Avoid the heat of
direct sunlight to avoid damage to the bumpers,
o-rings, and other rubber parts.
Loading the tool (fig. C)
These tools are equipped with a dual-load
magazine.
D51256.P65
• Select an appropriate collated nail stick. See
"Technical data".
• Load the magazine using one of the following
methods:
Loading and locking
• Insert collated nail stick (s) into the loading slot in
the rear of the magazine.
• Pull the nail pusher (11) rearward to fall behind
the nails.
Locking and loading
• Lock the nail pusher (11) in the back position.
• Insert collated nail stick (s) into the loading slot in
the rear of the magazine.
• Unlatch the nail pusher by pushing forward and
carefully slide the nail pusher forward to press
against the nails.
Actuating the tool (fig. D)
These tools are equipped with a trigger/lock-off
switch (1). When rotated to the right, this switch
prevents the tool from actuating.
When the switch is centred, the tool will be fully
operational. The tool can be operated using one of
two modes: sequential action mode or bump action
mode. The trigger installed on the tool determines
the mode of actuation.
Sequential action mode
The sequential action mode is used for intermittent
nailing when very careful and accurate placement is
desired.
• Fit the grey trigger as described above.
• Push the contact trip against the work surface.
• Pull the trigger to actuate the tool. Each trigger
pull with the contact trip pushed against the work
surface will drive one nail.
Bump action
The bump action mode is used for rapid nailing on
flat, stationary surfaces.
• Fit the black trigger as described above.
• To drive a single nail: Operate the tool as
described for sequential action.
