FILLING AND BLEEDING TOOL
NOTE:
Air bleeder assy (704153) is required.
WARNING:
Do not cycle tool without air bleeder assy (704153), or the button head cap screw (402482) and stat-o-seal (S572),
installed in the head cylinder assy (703109). Severe personal injury may result.
CAUTION:
Before filling handle assy (704132), the air piston assy (704121) should be all the way down.
CAUTION:
When forcing piston rod assy (704138) downward with head cylinder assy (703109) removed, hydraulic oil will
eject forcibly from handle assy (704132).
CAUTION:
Use CAUTION when removing button head cap screws (402482), stat-o-seals (S572) and air bleeder assy (704153).
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 in the tool, attach the air bleeder assy (704153) and connect tool to air line. Cycle tool ten times.
Disconnect air, remove the air bleeder assy (704153), and reinstall the button head cap screw (402482) and stat-o-seal (S572) on the
head cylinder assy (703109). Torque 35-40 inch lbs. This will insure the removal of any air from the hydraulic system and its
replacement with oil.

Should it become necessary to completely refill the tool (such as would be required after tool has been dismantled and reassembled),
take the following steps after depressing actuator lever assy
AND DISCONNECTING THE AIR SUPPLY:
1. Remove four button head cap screws (A-928) and head cylinder assy (703109) from handle assy (704132). Slowly push piston (751307)
completely forward.
2. Fill handle assy (704132) and the oil passage on top of handle assy (704132) with automatic transmission oil, Dexron III or
equivalent. When looking at the top of the handle assy (704132), the oil passage is the hole that is counterbored for o'ring (S832).
3. Replace head cylinder assy (703109) with care, ensuring gasket (704129) and o'ring (S832) are properly installed. Torque button
head cap screws (A-928) uniformly to 40 inch lbs. to prevent leakage around gasket (704129).
4. Remove button head cap screw (402482) and stat-o-seal (S572) from head cylinder assy (703109). Install air bleeder assy (704153)
and connect tool to air line. Cycle ten times to fully circulate oil through hydraulic system.
5.
DISCONNECT AIR FROM TOOL
. Remove air bleeder assy (704153) and install button head cap screw (402482) and stat-o-seal
(S572) on head cylinder assy (703109). Torque 35-40 inch lbs.
6.
Connect air supply. Cycle tool ten times and check stroke of .780 (19.8 mm) (see diagram below). We recommend using a pair of
dial calipers. With the actuator lever assy (704343) released, check dimension (A). With the actuator lever assy (704343)
depressed, check dimension (B). Subtract dimension (A) from dimension (B). If stroke is not consistent within 1/64" (.0156)
repeat bleeding steps 4-6.
