ASSEMBLING THE VALVE
All pneumatic components required are packed in a cartridge
assembly which is simply inserted into the tool. This section
describes how to assemble all the components together. However,
it is usually not necessary to completely disassemble the valve.
Refer to next section, "C
LEANING THE VALVE
on how to open the tool for regular maintenance. The following
procedure assumes that the gate/foot assembly (P-429) along with
the resting block P-534 are already installed. Refer to the
"Replacement Parts" document for a complete list and schematic
of the tool.
1.
It is usually not required to separate the head disk P-601A
from the head cap P-601. If necessary, insert the head disk
firmly in place into the head cap.
2.
Align the head cap P-601 with the two pins on the head P-606
and snap the cap in place. It is usually not required to remove
the head cap from the head.
3.
Check the condition of all rings and seals on the actuator
P-642, actuator cap P-644 and main valve P-643.
4.
Lightly lubricate actuator P-642 as shown and insert it into
valve P-643.
5.
Lightly lubricate the permanent seal of actuator cap P-644 as
shown. Do not lubricate the small o-ring (see part P-644C on
schematic). Insert the actuator cap as shown and forcibly
snap it into the actuator P-642
6.
Insert the valve sub-assembly completely into the head P-606.
7.
Screw the cylinder completely onto the head body P-606 and
tighten firmly by hand. Take care not do damage the threads.
Pull down the valve P-643 to sit it onto the cylinder.
8.
Check that the band-valve P-618A is properly installed onto
the main cylinder P-618.

9.
Check that the piston sub-assembly, including rings and
driving blade, is sliding easily into the cylinder P-618. It should
offer some resistance, but if it moves too easily, it may be
required to replace the piston wear-ring P-622A.
10. Insert the seal bushing P-525B in the lower section of main
body P-606 and engage it onto the upper portion of the
gate/foot assembly (P-429). A flat screwdriver can help
location the seal bushing correctly. Use the wooden handle of
the hammer to tap the seal bushing completely in place. It is
usually not necessary to pull-out the seal bushing P-525B for
maintenance.
11. With the tool in the upright position, push the bumper P-525A
in place, indexed onto the seal bushing P-525B and use the
wooden handle to seat the bumper in position.
12. Insert the piston sub-assembly into the main body P-616 and
engage the driving blade P-423 in the seal bushing opening.
Depress the safety contact P-562 to ensure that the driving
blade has engaged the gate/foot assembly guiding channel.
13. Loosen the lock P-616D and insert the whole head assembly
into the main body P-616; the main cylinder P-618 engaging

This tool features a head lock to
maintain firmly in place the head
assembly during operation. Before
inserting the head assembly, ensure
that the P-616D lock is free to swivel
and rotate it away from the head
opening. After inserting the head
assembly in place, rotate the P-616D
lock and tighten with the Allen key
using moderate force.
To remove the head assembly, simply unscrew the P-616D screw
¼ turn and rotate it counter-clockwise.
CLEANING THE VALVE
If the tool becomes sluggish or does not set the fastener, it may
indicate excessive dirt, dust, other particles, or even water, in the
head assembly, thereby impeding the cycling of the valve. The first
step in troubleshooting is to clean up the head assembly.
1.
Loosen (¼ turn) the head lock P-616D.
