FILLING & BLEEDING PROCEDURE:
NOTE:
Air bleeder assy (704153) and fill bottle (745263) are required.
WARNING:
Do not cycle tool without air bleeder assy, or button head cap screw and stat-o-seal, installed in tool head.
Severe personal injury may result.
CAUTION:
Before filling handle, air piston assy should be all the way down.
CAUTION:
When forcing piston rod assy downward with head cylinder removed, hydraulic oil will eject forcibly from handle.
CAUTION:
Use CAUTION when removing button head cap screw (402482), hydraulic oil may be under pressure.
WARNING:
Failure to follow these instructions carefully may result in severe personal injury.
To replace a small amount of oil start at step 18-23.
1. Ensure air piston ass'y (744121) is at the bottom of stroke by pushing piston rod ass'y (745344) all the way down.
2. Fill power cylinder (745331) and
3. Place gasket (745124) and o'ring (S832) on top of handle assy (744129).
4. Press manifold-handle (745303) down on power cylinder (745331) and install (4) button head cap screws (A-928) evenly.
Apply Loctite 242 and torque to 40 inch pounds.
5. Attach hydraulic hoses (A-1282) to manifold-handle (745303). (See hydraulic thread preparations Page 6)
6. Install barbed fitting (S1181) to manifold-handle (745303) and attach air line (704311) and hose clamp (A-144) and tighten.
7. Slide hose guard (703561) over all three hoses.
8. Push piston (745310) in head cylinder (745366) until you achieve .767" (19.5 mm) from full forward position. Stretch entire
tool out in a horizontal position across table or floor.
9. Attach handle-split (700326) to air line (704311) and secure handle-split (700326) to hydraulic hoses (A-1282). (See
hydraulic thread preparations Page 6)
10. Remove button head cap screw (402482) and stat-o-seal (S572) from manifold-handle (745303) and right hole (stamped #1) on
head cylinder (745366). Attach fill bottle (745263) to hole side stamped "P" on manifold-handle (745303).
11. Pump oil into head cylinder (745366) by squeezing fill bottle (745263) located at manifold-handle (745303) until oil comes out from right
hole stamped #1 on head cylinder (745366). Replace button head cap screw (402482) and stat-o-seal (S572) on head cylinder (745366)
hole stamped #1. Remove fill bottle (745263) and replace button head cap screw (402482) and stat-o-seal (S572) on manifold-handle
(745303) and torque both 35-40 inch lbs.
12. Remove button head cap screw (402482) and stat-o-seal (S572) from manifold-handle (745303) on rear hole side, stamped
"R" and head cylinder (745366) left hole stamped #2. Attach fill bottle (745263) to rear hole side, stamped "R", on manifold-
handle (745303). Pump oil into head cylinder (745366) until oil comes out of left hole stamped #2. Remove fill bottle
(745263) and replace button head cap screw (402482) and stat-o-seal (S572) on both and torque 35-40 inch lbs.
13. Stand handle assy (744129) on floor, extend hoses upward (onto a table) with head assembly sitting on an elevated surface.
14. Remove button head cap screw (402482) and stat-o-seal (S572) from manifold-handle (745303) hole stamped "P". Attach air bleeder assy
(704153) to manifold-handle (745303) hole stamped "P". Connect tool to air supply and cycle 10 times (removing any air bubbles).
15. Disconnect air supply and remove air bleeder assy (704153), and replace with button head cap screw (402482) and stat-
o-seal (S572) on manifold-handle (745303) hole marked "P" and torque 35-40 inch lbs.
16. Remove button head cap screw (402482) and stat-o-seal (S572) from manifold-handle (745303) of rear hole stamped "R".
Attach air bleeder assy (704153) to manifold-handle (745303) rear hole stamped "R".
17. Connect air supply, cycle tool 10 times until no air rises in bottle. Disconnect air supply. Remove air bleeder assy (704153)
and replace button head cap screw (402482) and stat-o-seal (S572) on hole stamped "R" and torque 35-40 inch lbs.
18. With piston (745310) at dimension .147" (3.7 mm) and air disconnected, remove button head cap screw (402482) and stat-o-
seal (S572) from hole #1 of head-cylinder (745366) and attach air bleeder assy (704153).
19. Connect air supply and cycle 10 times with piston at dimension (.147"). Disconnect air supply, remove air bleeder assy
(704153) and replace button head cap screw (402482) and stat-o-seal (S572) and torque 35-40 inch lbs.
20. Remove button head cap screw (402482) and stat-o-seal (S572) from hole #2 on head-cylinder (745366). Attach air bleeder
assy (704153), connect air and cycle tool 10 times.
21. With piston (745310) at dimension .147", disconnect air supply removed air bleeder assy (704153) and replace button head
cap screw (402482) and stat-o-seal (S572) on hole #2 of head cylinder (745366) and torque 35-40 inch lbs.
22. Connect air supply, cycle tool 10 times.
23. Check stroke of .620" (15.75 mm) (see below). We recommend using dial calipers. With the actuator released, check
dimension (A). Holding actuator in, check dimension (B). Subtract dimension (A) from dimension (B). If stroke is not within
1/64" (.0156) repeat steps 18-23.
