PLEASE CONTACT GAGE BILT FOR ALL OTHER SERIAL NUMBERS.
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 a 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
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 assembly (744129)
keeping hydraulic hose (A
-
317) towards plug (704313), located on handle assembly (744129) and torque button head cap screws (A
-
928)
to 40 inch lbs. (4.52 Nm).
4.
Push piston (743407) full forward. Install gasket (704129) and o
’
ring (S832) on manifold
-
head assembly (744306). Assemble head
cylinder assembly (743116) to manifold
-
head assembly (744306) and lever assembly (724017) using socket head cap screws
(400061 & 400066). Apply Loctite 242 to all cap screws and torque to 40 inch lbs. (4.52 Nm).
5.
Remove pin and lever from lever assembly (724017).
Coil tool hoses up on bench and lay handle assembly (744129) down on side
so that the hole marked #4 on manifold handle (744303) is to the top. Set head cylinder assembly (743116) over a small bucket or can.
Completely fill up fill bottle (745263).
6.
Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from manifold
-
handle (744303) hole #4 and manifold
-
head assembly (744306)
hole #4. Connect fill bottle (745263) to manifold
-
handle (744303) hole marked #4.
7.
In one continuous squeeze force oil into manifold
-
handle (744303) until oil starts to flow from bleeder hole marked #4 on manifold
-
head assembly (744306). While still squeezing the fill bottle (745263) use other hand to replace button head cap screw (402482)
and stat
-
o
-
seal (S572) on manifold
-
head (744306) and torque to 35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not over tighten. This may
require two people.
8.
Remove fill bottle (745263) and replace stat
-
o
-
seal (S572) and button head cap screw (402482) on manifold
-
handle (744303) and
torque to 35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not over tighten.
9.
Proceed to bleeding instructions on pg. 12 to remove air from hydraulic system.
FILLING PROCEDURE
WARNING:
Do not cycle tool without air bleeder assembly (704153), or the screw and stat
-
o
-
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 (744129), air piston assembly (744121) must be all the way down.
CAUTION:
When forcing piston rod assembly (744136) downward, with head cylinder assembly (743116) removed, hydraulic oil will
eject forcibly from handle assembly (744129).
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.
Note:
•
Fill Bottle (745263) (sold separately) is required.
