BLEEDING PROCEDURE:
Note:
•
Air Bleeder Assembly (704153) and Fill Bottle (745263) (sold separately) are required.
•
To replace a few drops of oil use bleeder bottle (731163) (sold separately).
1.
Stand handle assembly (722132) on floor, extend hoses upward (onto a table) with head assembly sitting on an elevated surface.
Turn air supply down to 50
-
60 psi. (3.4 bar
-
4.1 bar).
2. Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from manifold
-
handle (730303) hole stamped
“
P
”.
Attach air bleeder
assembly (704153) to manifold
-
handle (730303) hole stamped
“
P
”.
Connect tool to air supply and cycle ten times (removing any air bubbles).
3.
Disconnect air supply and remove air bleeder assembly (704153), replace with button head cap screw (402482) and stat
-
o
-
seal (S572)
on the manifold
-
handle (730303) hole stamped
“
P
”
and torque 35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not over tighten.
4. Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from rear hole stamped
“
R
”
on manifold
-
handle (730303) and
relieve the pressure.
Caution:
Oil may squirt out from bleeder hole, cover with a rag.
5. Replace button head cap screw (402482) and stat
-
o
-
seal (S572) on hole stamped
“
R
”
and torque 35
-
40 inch lbs. (3.95
-
4.52 Nm).
Do not over tighten
6. With piston (731904) at dimension
.250” (6.4
mm) and air disconnected, remove button head cap screw (402482) and stat
-
o
-
seal (S572)
from front hole of head cylinder assembly (731912) and attach air bleeder assembly (704153).
7. Connect air supply and cycle tool ten times (removing any air bubbles) with piston at dimension
.250” (6.4
mm). Disconnect air
supply, remove air bleeder assembly (704153) and replace button head cap screw (402482) and stat
-
o
-
seal (S572) and torque
35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not over tighten.
8.
Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from rear hole on head cylinder assembly (731912).
Caution:
Oil
may squirt out from bleeder hole, cover with a rag. Attach fill bottle (745263) and hand pump oil into the head cylinder assembly (731912)
until no air rises into fill bottle (745263). Remove fill bottle (745263) and replace B.H.C.S. (402482) and stat
-
o
-
seal (S572) on rear
hole of head cylinder assembly (731912) and torque 35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not over tighten.
9.
Connect air supply, cycle tool ten times.
10.
Check stroke of
.600” (15.24
mm) using instructions a thru c and diagrams below. We recommend using dial calipers.
a. With the actuator lever assembly (704343) released, check dimension (A).
b. Holding actuator lever assembly (704343) down, check dimension (B).
c. Add dimension (A) to dimension (B). If stroke is not within
1/64” (.396
mm) follow steps 11 & 12 below then re
-
check
stroke with calipers or depth gage (A
-
1935). If stroke still fails to achieve
.600” (15.24
mm) and is not within
1/64” (.396
mm),
then repeat bleeding procedure until stroke met.
For your consideration, Gage Bilt offers a depth gage (A
-
1935) to help simplify and more accurately check your tool stroke.
Please contact Gage Bilt for more information.
11.
Disconnect the air supply. Check dimension (A)
(.250”).
Remove both B.H.C.S.
’
s (402482) & stat
-
o
-
seals (S572) from top of head
cylinder assembly (731912) and push the piston (731904) forward to dim (A)
(.250”).
Caution:
Oil may squirt out from bleeder
holes, cover with a rag.
12.
Attach fill bottle (745263) to the rear hole on head cylinder assembly (731912) and pump oil into the head cylinder (731912) until
no air rises into the fill bottle (745263). Remove the fill bottle (745263) and replace both of the B.H.C.S.
’
s (402482) and stat

-
seals (S572).
Torque 35
-
40 inch lbs. (3.95
-
4.52 Nm). Repeat step #10 (stroke check) above.

WARNING:
Do not cycle tool without air bleeder assembly (704153), or the screw and stat

seal, installed in tool head. Severe
personal injury could result.
WARNING:
Use CAUTION when removing screws, air bleeder assembly (704153) and fill bottle (745263). Hydraulic oil may be under pressure.
CAUTION:
Before filling handle assembly (722132), air piston assembly (704121) should be all the way down.
CAUTION:
When forcing piston rod assembly (731333) downward, with head cylinder assembly (731912) removed, hydraulic oil will
eject forcibly from handle assembly (722132).
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.
