FILLING & BLEEDING PROCEDURE:
NOTE:
Fill bottle assy (745263) and air bleeder assy (704153) are required.
NOTE:
To replace a small amount of oil follow bleeding steps 5-6.
WARNING:
Do not cycle tool without fill bottle assy (745263), air bleeder assy (704153) or the button head cap screw (402482)
and stat-o-seal (S572), installed in the head cylinder assy (704182). Severe personal injury may result.
CAUTION:
Before filling handle assy (744129), the air piston assy (744121) should be all the way down.
CAUTION:
When forcing piston rod assy (744136) downward, hydraulic oil will eject forcibly from handle assy (744129).
CAUTION:
Use CAUTION when removing button head cap screws (402482), stat-o-seals (S572), air bleeder assy (704153) and fill bottle assy
(745263). Hydraulic oil may be under pressure.
WARNING:
Failure to follow these instructions carefully may result in severe personal injury.
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 30534 or similar Teflon® infused pipe dope is
recommended.
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. Use 1 1/2 wraps of tape on each
thread. Cut off all loose tape ends. Tighten until fitting feels snug and then go 1/2 to a full turn past that point.
CAUTION:
Over tightening can easily distort the threads.

To replace a small amount of oil in the tool, attach the air bleeder assy (704153) and connect tool to air line. Cycle ten times. Discon-
nect air, remove the air bleeder assy (704153), and reinstall the button head cap screw (402482) and stat-o-seal (S572). This will en-
sure the removal of any air from the hydraulic system and its replacement with oil.
FILLING:
1. Put the piston rod wrench (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 counter bore
for o’ ring (S832). Do not overfill causing oil to go in air passage hole.
3. Install o’ ring (S832), gasket (704129), button head cap screws
(
A-928) and manifold-handle (744303) to handle assy (744129)
keeping hydraulic hose (A-1282) towards plug (704313). Torque button head cap screw to 40 inch lbs.
4. Push piston (704507) full forward. Install gasket (704129), o’ ring (S832) and socket head cap screws (400061) on handle-split (700323).
Assemble head cylinder assy (704182) to handle-split (700323). Apply Loctite 242 to all cap screws and torque to 40 inch lbs.
5. Coil tool up on bench and lay manifold-handle (744303) down on side so that the hole marked #4 is to the top. Rest head cylinder assy
(704182) over a small bucket or can. Completely fill up fill bottle assy (745263).
6. Remove button head cap screw (402482) and stat-o-seal (S572) from manifold-handle (744303) hole marked #4. Connect fill bottle
assy (745263) to manifold-handle (744303) hole marked #4. Remove button head cap screw (402482) and stat-o-seal (S572) from
head cylinder assy (704182).
7. In one continuous squeeze force oil into manifold-handle (744303) until oil starts to flow from bleeder hole on head cylinder assy
(704182). While still squeezing the fill bottle assy (745263), use other hand to replace button head cap screw (402482) and stat-o-
seal (S572) on the head cylinder assy (704182) and torque to 35-40 inch lbs. This may require two people.
8. Remove fill bottle assy (745263) from manifold-handle (744303) hole marked #4 and replace stat-o-seal (S572) and button head
cap screw (402482) and torque to 35-40 inch lbs.
BLEEDING:
1. Stand handle assy (744129) on floor, stretch hose and head assy upward and lay flat on a table or bench. When bleeding tool
always keep the head assy higher than the handle assy (744129).
2. Remove button head cap screw (402482) and stat-o-seal (S572) from manifold-handle (744303) hole marked #3. Attach air bleeder
assy (704153) to manifold-handle (744303) hole marked #3 in an upright position.
3. Connect the tool to air supply and cycle tool ten times holding the actuator lever assy (704343) down for 2-3 seconds between
cycles to remove any air from the tool.
4. Disconnect air supply. Remove air bleeder assy (704153) from manifold-handle (744303) and replace with button head cap screw
(402482) and stat-o-seal (S572) and torque 35-40 inch lbs.
5. Remove button head cap screw (402482) and stat-o-seal (S572) from head cylinder assy (704182) and attach air bleeder assy
(704153) in an upright position.
6. Connect air supply. Cycle tool ten times removing any air bubbles.
7. Disconnect air supply. Remove air bleeder assy (704153) and replace button head cap screw (402482) and stat-o-seal (S572) on
the head cylinder assy (704182) and torque 35-40 inch lbs.
8.
Connect air supply. Cycle tool ten times and check stroke of .600” (19.3 mm) (see diagram below). We recommend using dial calipers.
With the actuator lever assy (704343) released, check dimension (A). Holding actuator lever assy (704343) check dimension (B). Subtract
dimension (A) from dimension (B). If stroke is not consistent within 1/64" (.0156) repeat bleeding steps 5-6.
