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 (713121). 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 with head cylinder assy (713121) removed, hydraulic oil
will eject forcibly from handle assy (744129).
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 ten times.
Disconnect air, remove the air bleeder assy (704153), and reinstall the button head cap screw (402482) and stat-o-seal (S572). This
will ensure 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 the air actuator assy (704130)
AND DISCONNECTING THE AIR SUPPLY:
1. Remove head cylinder assy (713121) from handle assy (744129). Slowly push piston (713211) completely forward.
2. Fill handle assy (744129) and the oil passage on top of handle assy (744129) with automatic transmission oil, Dexron III or
equivalent. When looking at the top of the handle assy (744129), the oil passage is the hole that is counterbored for o'ring
(S832).
3. Replace head cylinder assy (713121) with care, ensuring gasket (704129) and o'ring (S832) are properly installed. Torque four
button head cap screws (402479) to 40 inch lbs. uniformly to prevent leakage around gasket (704129).
4. Remove button head cap screw (402482) and stat-o-seal (S572) from head cylinder assy (713121). 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). Install button head cap screw (402482) and stat-o-seal (S572)
on the head cylinder assy (713121).
6. Reconnect air and cycle tool ten more times.
7. Check stroke of .760” (19.3 mm) (See figures below). We recommend using calipers. With the air actuator assy (704130)
released, check dimension (A). While holding air actuator assy (704130) in, check dimension (B). Subtract dimension (A)
from dimension (B). If stroke is not consistent within 1/64" (.0156” or .392 mm) repeat steps 4-7.
.180 (4.6mm)
.940 (23.9mm)
