11. Detach teeth (#21) by driving (2) roll pins (#20) from
carriage and teeth (#32 and #21).
12. Apply heat as needed to break down thread lock
adhesive on threaded end of piston rod.
13. Detach stop spacer (#9) by removing set screw (#33)
and then use a spanner wrench to remove stop spacer
(#9) from carriage (#32).
Throttle
1. Remove air valve assembly (#27) from housing (#1).
2. Remove o-ring, ball, valve ball retainer and o-ring (#28,
#29, #30 and #31).
TO RE-ASSEMBLE
1. Assemble o-ring, valve ball retainer, ball and o-ring
(#31, #30, #29 and #28) and insert into throttle bore of
housing (#1).
2. Install air valve assembly (#27) into throttle bore of
housing (#1). (Do Not Over-Tighten).
3. Install stop spacer (#9) onto the carriage (#32). Use
Loctite #242 or equivalent.
4. Install set screw (#33) into carriage, locking stop spacer
onto carriage.
5. Install teeth (#21) by driving in (2) roll pins (#20) until
flush with carriage.
6. Connect outer jaw to left arm link (#15 and #13) by
driving roll pin (#14) in aligned holes.
7. Connect inner jaw to right arm link (#18 and #19) by
driving roll pin (#14) in aligned holes. (Make sure you
match the correct jaw with the correct arm link for the
tool to operate correctly.)
8. Connect jaws and arm link assemblies to clevis (#10) by
driving roll pin (#12) into aligned holes.
9. Place piston rod (#6) into a vise with long threaded end
sticking out.
10. Install piston (#4) onto long threaded end of the piston
rod with piston rod nut (#3) and remove from vise. (Use
Loctite #242 or equivalent on both piston and flexlock
nut.)
11. Install bumper and return spring (#7 and #8) onto piston
rod.
12. Place jaws, arm linkage and clevis assembly onto
carriage.
13. Insert piston rod, return spring, bumper and piston
assembly through the carriage and connect to the clevis.
(Use Loctite #242 or equivalent.)
14. Install set screw (#11) into clevis locking piston rod to
clevis.
15. Pivot jaws and arm linkage apart so that the slide (#16)
can be installed onto carriage.
16. Install magazine assembly (#22) with (4) socket head
cap screws (#24).
17. Install o-ring (#5) onto the piston.
18. Apply lubrication to piston, o-ring, threaded stop spacer,
housing bore and thread in housing.
19. Install front end assembly into housing. (Be careful not
to damage the o-ring during installation.) Do not over-
tighten front end assembly onto the housing.
20. Install (2) socket head cap screws (#2), locking front end
assembly into place. Do not over tighten as damage
could occur to front end assembly.
21. Cycle tool to ensure everything operates freely.
22. Cycle tool with rings in magazine. If tool is picking up
next ring or breaking next ring away from the strip,
disconnect air from tool.
23. Push slide back toward the housing and remove slide.
24. Install wavy washer onto the post of the slide.
25. Re-install slide in tool.
26. Test tool again for picking up next ring. If picking up
next ring, repeat steps 24 through 27.
27. Make sure tool is disconnected from air supply. Push
slide toward teeth area. Install socket head cap screw
(#25) into carriage. This keeps the slide from coming
out during use. If the slide is not pushed forward during
socket head cap screw installation, you will break the
carriage.
FILTER AND REGULATOR
1. The air line should always contain a filter and regulator
unit to provide the tool with a constant flow of clean, dry
air. If moisture and contaminates are allowed to enter
the tool, the tool’s serviceable life will be decreased.
2. The regulator should be set between 70 and 90 psi. (4.8
to 6.2 bar). Never operate this tool beyond 100 psi. (6.9
bar).
