ASSEMBLING THE TOOL
This section describes how to re-assemble the tool after
maintenance. The following procedure assumes that the
gate/foot assembly along with the resting block are
already installed.
[1] Insert the seal bushing in the lower section of main
body and engage it onto the upper portion of the
gate/foot assembly. A flat screwdriver can help locate
it correctly. Use the wooden handle of the hammer to
tap the seal bushing completely in place.
Note: select the appropriate seal bushing:
- use P-525B for the "L" or "T" nailers
- use P-525C for staplers
[2] Check & lubricate the valve assembly. Insert into the
head and ensure that it is sliding easily.
[3] Snap the cylinder onto the head. Check that the band-
valve on the cylinder is properly installed.
[4] Insert the piston assembly about 1" into the bottom
end of the cylinder.
[5] Push the bumper into the bottom end of the cylinder.
[6] With the head lock loosened, engage the whole
assembly into the tool, with the driving blade engaged
thru the opening of the seal bushing. Depress the
safety contact and engage down completely into
gate/foot assembly guiding channel.
Insert the Alen key into one of the side holes and
screw the head assembly completely. Take care not
do damage the threads. Tighten by hand.
NEVER apply threadlocker or adhesive onto
head threads.
[7] Rotate the head lock clockwise and tighten with
moderate force with the Allen key.
After reassembly, always actuate the tool
repeatedly WITHOUT FASTENERS against a
piece of wood to insure proper operation.
