seal, installed in tool head. Severe
personal injury could result.
WARNING:
Use CAUTION when removing screws, air bleeder assembly (704153) and fill bottle (745263). Hydraulic oil may be
under pressure.
CAUTION:
Before filling handle assembly (704132), air piston assembly (704121) must be all the way down.
CAUTION:
When forcing piston rod assembly (704138) downward, with head cylinder assembly (703124) removed, hydraulic oil
will eject forcibly from handle assembly.
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.

IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 545 or equivalent or a non
-
hardening Teflon® thread
compound such as Slic
-
tite®. Tighten until fitting feels snug and then continue to tighten 1/2 to 1 full turn.
CAUTION:
Over tightening
can easily distort the threads. DO NOT USE TEFLON® TAPE.
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.
1.
Put the piston rod wrench assembly (704149) into the top of handle assembly (744129), pushing down firmly until piston rod
assembly (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 assembly (744129) the oil passage is the hole that has a
counter bore for o
’
ring (S832). Do not overfill causing oil to go in air passage hole.

-
head assembly (744306). Apply Loctite® 242 to
all socket head cap screws and torque socket head cap screws (400061 & 400066) to 40 inch lbs. (4.52 Nm).
5.
Remove lever assembly (724017) from manifold
-
head assembly (744306).
