Set-up & Loading nails into the magazine
Warning! Disconnect the air hose from the nailer air inlet.
1) Pull the feed shoe all the way to the rear, until it latches. See Fig.1.
2) Orient the strip of nails with points down and drop the nails into the magazine.
3) Slide the nails forward in the magazine. The magazine will hold 100 nails.
4) To unlock the feeder shoe, pull it backwards, press the lock release (A) Fig.2 to
disengage the feeder shoe lock to slide forward towards the nails.
5) Adjust the 360 degree air deflector to blow air away from the operator by simply
turning it by hand.
Depth of Drive Adjustment
The depth a nail is driven is adjusted by the depth adjustment plate (A) Fig.3. The
factory setting is set to the maximum depth. To adjust,
1) Loosen cap screw (B) with hex. key.
2) Slide depth adjustment plate to the desired position and retighten cap screw. Sliding
the plate upwards increases the depth of drive and moving the plate downwards
decreases the depth of drive.
3) Test fire a nail and check depth, repeat as necessary.
The amount of air pressure required will vary, determine the lowest setting that will
consistantly perform the job at hand. Air pressure exceeding that which is required can
cause premature wear and/or damage the nailer. A plastic protective tip (C) is provided
to reduce marring of the work surface. It can be removed to increase depth of drive.
Warning! Disconnect the air hose from the nailer air inlet before removing plastic
protective tip.
Sequential and bump fire modes
Operational modes
This framing nailer may be operated in either "sequential" or "bump fire" mode. This
framing nailer is shipped with a black trigger installed, this black trigger allows
"sequential" firing. A separate red trigger for "bump fire" mode is included.
Sequential Mode
When the black trigger is installed, this framing nailer is in "sequential" mode. This
method is recommended when precise nail placement is required. In sequential mode,
the trigger needs to be pulled and released each time a nail is driven. The framing
nailer is actuated by depressing the framing nailer nose against the work surface.
Bump Fire Mode
When the red trigger is installed, this framing nailer is in "bump fire" mode. This method
is recommended when less precise nail placement is required. In bump fire mode, the
trigger must be depressed with the framing nailer nose off the work surface. Then, the
nose of the framing nailer is tapped against the work surface causing a nail to be
driven. Each time the framing nailer nose is depressed, a nail is driven.
Changing Modes
To change the firing mode of your framing nailer, remove the o-ring (Part#232) which
secures the trigger pin (#233). Remove the trigger pin, trigger, and the trigger spring
(#230). Interchange the trigger only and reassemble the trigger assembly.
Clearing jams
Warning! Disconnect the air hose from the nailer air inlet.
1) Remove the remaining nails from the nailer.
2) Pull the feeder shoe all the way to the rear until it latches.
3) Slide nails to the rear and remove them from the magazine.
4) Using a pair of needle nose pliers or a flat screwdriver, remove the bent nail from the
back of the nose piece. If you cannot remove the nail this way, follow these instructions;
a) Remove both cap screws (A-one on each side) Fig.4, remove nuts (B-only one is
shown) and slide magazine back, off the nose piece.
b) Remove bent nail and reassemble in the reverse order.
