FILLING AND BLEEDING INSTRUCTIONS
WARNING:
DO NOT CYCLE TOOL WITHOUT AIR BLEEDER, OR THE SCREW AND STAT-O-SEAL, INSTALLED IN HEAD
CYLINDER SEVERE PERSONAL INJURY MAY RESULT.
CAUTION:
BEFORE FILLING HANDLE, AIR PISTON SHOULD BE ALL THE WAY DOWN.
CAUTION:
WHEN FORCING PISTON ROD ASSEMBLY DOWNWARD WITH HEAD CYLINDER ASSEMBLY REMOVED,
HYDRAULIC FLUID WILL EJECT FORCIBLY FROM HANDLE.
To replace a small amount of oil in the tool cycle tool to rear position disconnect air and follow steps 6-15 below.
Should it become necessary to completely refill the tool (as would be required after tool has been dismantled and
reassembled), take the following steps.
1. Ensure air piston ass’y (744121) is at the full bottom of stroke by pushing power piston rod ass’y (745334) down.
2. Fill power cylinder (745331) and oil passage (hole for o’ring S832 ) to the top, being careful not to get oil into the air
passage.
3. Place gasket (745124) and o'ring (S832) on top of the handle (744129).
4. Push piston (745310) to rear of head cylinder (745366) until it stops. (DIM “B”)
5. Press head cylinder (745366) down on top of handle (744129), being careful not to tear o'ring (403805) on top of
power cylinder (745331), install button head cap screws (402479) and tighten evenly, to 40 inch lbs.
6. When holding tool remove the right (hole stamped #1) button head cap screw (402482) and stat-o-seal (S572) from
side of head cylinder (745366). Attach air bleeder ass’y (704153) making sure left (hole stamped #2) button head
cap screw (402482) and stat-o-seal (S572) are in place.
7. Connect tool to air supply. The piston (745310) will then move to forward position. (DIM “A”). Cycle tool
10 times.
9. Disconnect air supply then remove air bleeder ass’y (704153) and replace button head cap screw (402482) and
stat-o-seal (S572).
10. Carefully remove button head cap screw (402482) and stat-o-seal (S572) from left hole (stamped #2). (NOTE: Left
hole (stamped #2) could be under pressure.)
11. Attach air bleeder ass’y (704153) to left hole (stamped #2).
12. Connect tool to air supply. Cycle tool 10 times until no air rises in the bottle.
13. Cycle tool to rear position. While holding in air actuator ass’y, disconnect air supply then remove air bleeder ass’y
(704153) and replace button head cap screw (402482) and stat-o-seal (S572).
14. Connect tool to air supply and cycle tool 5 times.
15. Check stroke of .620 (15.75 mm) (see below). We recommend using dial calipers. With the air actuator ass’y
released check dimension (A). Holding air actuator ass’y in, check dimension (B). Subtract dimension (A) from
dimension (B). If stroke is not consistent within 1/64" (.0156) repeat steps 6-15.
CAUTION:
Use CAUTION when removing button head cap screw (402482), hydraulic fluid may be under pressure.
WARNING:
Failure to follow these instructions carefully may result in severe personal injury.
