PLEASE CONTACT GAGE BILT FOR ALL OTHER SERIAL NUMBERS.
BLEEDING PROCEDURE:
Images may not reflect actual tool
WARNING:
Do not cycle tool without air bleeder assembly (704153), or the screw and stat
-
o
-
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.
WARNING:
When replacing a small amount of oil, cycle tool to rear position. While still holding actuator lever assembly (704343),
disconnect air supply.
CAUTION:
Before filling handle assembly (722132), air piston assembly (704121) must be all the way down.
CAUTION:
When forcing piston rod assembly (731333) downward, with head cylinder assembly (731199) removed, hydraulic oil will
eject forcibly from handle assembly (722132).
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.

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

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
-

-
seal (S572) on hole stamped
“
R
”
and torque 35
-
40 inch lbs. (3.95
-

Do not over tighten
6. With piston (731211) at dimension
.185” (4.7
mm) and air disconnected, remove button head cap screw (402482) and stat
-
o
-
seal (S572)
from front hole of head cylinder assembly (731199) and attach air bleeder assembly (704153).
7. Connect air supply and cycle tool ten times (removing any air bubbles) with piston at dimension
.185” (4.7
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
-

8.
Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from rear hole on head cylinder assembly (731199).
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
(731199) 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 (731199) 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 d and diagrams below. We recommend using dial calipers.
a. With the actuator released, check dimension (A).
b. Holding actuator in, check dimension (B).
c. Subtract dimension (A) from 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).
d. 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)
(.185”).
Remove both B.H.C.S.
’
s (402482) & stat

o
-
seals (S572) from top of head
cylinder assembly (731199) and push the piston (731211) forward to dim (A)
(.185”).
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 (731199) and pump oil into the head cylinder (731199) until no air rises into
the fill bottle (745263). Remove the fill bottle (745263) and replace both of the B.H.C.S.
