Air fi tting (fi g. A)
These tools have a standard 3/8" pipe thread for
the air fi tting (2). The tool is assembled with a 3/8" to
1/4" adapter installed in the end cap.
• Wrap the male end of the fi tting with Tefl on tape
to prevent air leaks.
• To install a 1/4" fi tting, screw the fi tting into the
3/8" to 1/4" adapter in the end cap and tighten
fi rmly.
• To install a 3/8" fi tting, remove the 3/8" to 1/4"
adapter, if present. Screw the fi tting into the end
cap and tighten fi rmly.
Instructions for use
Always observe the safety instructions
and applicable regulations.
Preparing the tool (fi g. 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 fi tting on the tool.
• Check for audible leaks around valves and gaskets.
• Set the air pressure to the minimum
recommended operating pressure.
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 10 to 15 drops of D WALT pneumatic tool
E
oil (or winter-weight pneumatic oil containing
ethylene glycol) into the air inlet.
• Set the air pressure to a maximum of 5.5 bar.
24
• Connect the air hose to the fi tting 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 (fi g. C)
Always disconnect the tool from the air
supply before loading fasteners.
• Lock the nail pusher (11) in the back position.
• Select an appropriate collated nail stick.
See "Technical data".
• Insert collated nail stick (s) into the loading slot on
top of the magazine.
• Unlatch the nail pusher by pulling rearward and
carefully slide the nail pusher forward to press
against the nails.
Actuating the tool (fi g. 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.
