FILLING PROCEDURE
WARNING:
Do not cycle tool without air bleeder assy (704153), or the screw and stat
-
o
-
seal, installed in tool head. Severe personal injury could result.
CAUTION:
Before filling handle assy (744129), air piston assy (744121) should be all the way down.
CAUTION:
When forcing piston rod assy (744136 )downward, with head cylinder assy (703119) removed, hydraulic oil will eject forcibly
from handle assy .
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.
CAUTION:
Use CAUTION when removing screws, air bleeder assy (704153) and fill bottle (745263). Hydraulic oil may be under pressure.
Note:
Air Bleeder Assy (704153) and Fill Bottle (745263), are required.
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 545 or equivalent.
CAUTION:
Teflon tape is an
excellent thread sealer, however, if it is not properly applied, pieces of Teflon may enter the hydraulic system and cause malfunction
or damage. Wrap threads 1 ½ times keeping tape one full thread up from corner and face. Cut off all loose tape ends. Tighten until
fitting feels snug and then continue to tighten 1/2 to 1 full turn.
CAUTION:
Over tightening can easily distort the threads.
1.
Put the piston rod wrench assy (704149) into the top of handle assy (744129), pushing down firmly until piston rod assy (744136)
is completely in the down position.
2.
Fill oil passage and reservoir with Automatic Transmission Oil, Dexron III or equivalent. The reservoir is the area surrounding the
power cylinder (743131). When looking at the top of the handle assy (744129), the oil passage is the hole that has a counterbore
for o’ring (S832). Do not overfill causing oil to go in air passage hole.
3.
Install gasket (704129), o’ring (S832), button head cap screws (A
-
928) and manifold
-
handle (744303) to handle assy (744129)
keeping hose assy (A
-
122) towards plug (704313).
4.
Push piston (751307) full forward. Install gasket (704129) and o’ring (S832) on handle
-
split (700323). Assemble head cylinder assy
(703119) to handle
-
split (700323) using socket head cap screws (400061). Apply Loctite 242 to all cap screws and
torque to 40
inch lbs.
5.
Remove pin and lever from actuator lever assy (704343).
Coil tool hoses up on bench and lay handle assy (744129) down on side
so that the hole marked #4 on manifold handle (744303) is to the top. Set head cylinder assy (703119) over a small bucket or can.

cylinder assy (703119).
7.
In one continuous squeeze force oil into manifold
-
handle (744303) until oil starts to flow from bleeder hole on head cylinder assy
(703119). While still squeezing the fill bottle (745263), use other hand to replace button head cap screw (402482) and stat
-
o
-
seal (S572) on
head cylinder assy (703119) and torque to 35
