FILLING AND BLEEDING INSTRUCTIONS
NOTE:
Fill bottle Assy (745163) is required.
WARNING:
Do not cycle tool without fill bottle assy (745163), or the button head cap screw (402482) and stat-o-seal (S572),
installed in the head cylinder (731298). Severe personal injury may result.
CAUTION:
Before filling handle assy (722132), the air piston assy (704121) should be all the way down.
CAUTION:
When forcing piston rod assy (731333) downward with head cylinder (731298) removed, hydraulic oil will eject
forcibly from handle assy (722132).
CAUTION:
Use CAUTION when removing button head cap screws (402482), stat-o-seals (S572) and 4oz fill bottle assy (745163). 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, cycle tool to rear position disconnect air and follow steps 6-16 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. Remove four button head cap screws (A-928). Remove head cylinder (731298) from handle assy (722132). Ensure air piston assy
(704121) is at the full bottom of stroke by pushing power piston rod assy (731333) down.
2. Fill power cylinder (731237) and oil passage (hole for o’ring S832 ) to the top, being careful not to get oil into the air passage.
3. Place gasket (704129) and o'ring (S832) on top of the handle assy (722132).
4. Push piston (731211) to rear of head cylinder (731298) until it stops. (DIM “B”)
5. Press head cylinder (731298) down on top of handle assy (722132), being careful not to tear o'ring (403773) on top of power cylinder
(731237), install button head cap screws (A-928) and tighten evenly to 40 inch lbs.
6. Lay tool down on its side with bleeder screws facing up. Carefully remove the front button head cap screw (402482) and stat-o-seal
(S572) from hole stamped #1 on side of head cylinder (731298). Attach fill bottle assy (745163) making sure button head cap screw
(402482) and stat-o-seal (S572) are in place on hole stamped #2.
(NOTE: Front hole stamped #1 could be under pressure.)
7. Connect tool to air supply. Piston (731211) will then move to forward position. See (DIM “A”). Cycle tool ten times.
8. Disconnect air supply. Check “A” dimension.
If “A” dimension checks
within specifications, proceed to step 9.
If “A” dimension checks
long, remove (211102) nut and (240102) retaining nut stop from (752301) nose fitting, thread bleed nut
(731010) (Sold Separately) onto piston (731211) until snug, bringing piston (731211) full forward to “A” dimension. Remove bleed nut (731010).
9. Remove fill bottle assy (745163) and replace button head cap screw (402482) and stat-o-seal (S572) on front hole (stamped #1) of head cylinder
(731298) and torque 35-40 inch lbs.
10. Connect air supply and cycle tool to rear position. While depressing actuator lever assy, disconnect air supply, with piston in “B” position.
11. Carefully remove the back button head cap screw (402482) and stat-o-seal (S572) from hole stamped #2 on side of head cylinder
(731298). Attach fill bottle assy (745163) making sure button head cap screw (402482) and stat-o-seal (S572) are in place on hole
stamped #1.
NOTE: Back hole stamped #2 could be under pressure. )
12. Connect tool to air supply. Cycle tool ten times until no air rises in the bottle.
13. Disconnect air supply. Remove (211102) nut and (240102) retaining nut stop from (752301) nose fitting. Thread bleed nut (731010)
(Sold Separately) onto piston (731211) until snug, bringing piston full forward to “A” dimension.
14. Remove fill bottle assy (745163) and replace button head cap screw (402482) and stat-o-seal (S572) on back hole (stamped #2) of
head cylinder (731298) and torque 35-40 inch lbs. Remove bleed nut (731010).
15. Connect tool to air supply and cycle tool ten times.
16. Check stroke of .600” (15.2 mm) (see below). We recommend using dial calipers. With the actuator lever assy (704343) released
check dimension (A). Holding actuator lever assy (704343) in, check dimension (B). Subtract dimension (A) from dimension (B). If
stroke is not consistent within 1/64" (.0156) repeat steps 6-16.
