BLEEDING PROCEDURE
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.
CAUTION:
Before filling handle assembly (744129), air piston assembly (744121) should be all the way down.
CAUTION:
When forcing piston rod assembly (745347) downward, with cylinder (204300) removed, hydraulic oil will eject forcibly
from handle assembly (744129).
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.
CAUTION:
Use CAUTION when removing screws, air bleeder assembly (704153) and fill bottle (745263). Hydraulic oil may be under pressure.
Note:
•
Air Bleeder Assembly (704153) (sold separately) & Fill Bottle (745263) (sold separately) are required.

To replace a small amount of oil in the tool follow all steps for bleeding procedure.
1. Stand handle assembly (744129) on floor and stretch hose assembly (A1668) upward on a table or bench, laying head cylinder (204300)
flat on its side.
2. Ensure air piston assembly (744121) is up by connecting tool to air and piston assembly (206129) is full forward, dimension
“
A
”.
Disconnect air from tool.
3. If dimension
“
A
”
does not check full forward, remove button head cap screws (402482) and stat
-
o
-
seals (S572) from holes marked
“
P
”
and
“
R
”
on head cylinder (204300).
4. Using a
7/16” (10
mm) hex key, push piston (206129) forward until dimension
“
A
”
checks correct. Attach button head cap screws
(402482) and stat
-
o
-
seal (S572) to holes marked
“
P
”
and
“
R
”
on head cylinder (204300).
5. Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from hole marked
“
P
”
on manifold handle (745303) and attach air
bleeder assembly (704153). Cycle tool ten times.
6. Disconnect air from tool and remove air bleeder assembly (704153). Attach button head cap screw (402482) and stat
-
o
-
seal (S572)
to hole marked
“
P
”
on manifold handle (745303).
7. Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from hole marked
“
P
”
on head cylinder (204300).
8. Attach air bleeder assembly (704153) to hole marked
“
P
”
on head cylinder (204300). Cycle tool 10 times.
9. Disconnect tool from air. Remove air bleeder assembly (704153) and attach button head cap screw (402482) and stat
-
o
-
seal (S572)
to hole marked
“
P
”
on head cylinder (204300).
10. Connect tool to air and cycle tool to rear position (dimension
“
B
”).
While hold down actuator (704130) disconnect air from tool.
11. Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from hole marked
“
R
”
on head cylinder.
Caution tool is under pressure.
12. Attach air bleeder assembly (704153) to hole marked
“
R
”
on head cylinder (204300). Cycle tool 10 times.
13. Cycle tool to rear position (dimension
“
B
”).
While holding down actuator (704130) disconnect air from tool.
14. Remove air bleeder assembly (704153) and attach button head cap screw (402482) and stat
-
o
-
seal (S572) to hole marked
“
R
”
on
head cylinder (204300).
15. Connect tool to air. Slowly loosen button head cap screw (402482) from hole marked
“
R
”
on head cylinder (204300) allowing
excess oil to seep out. Tighten button head cap screw.
16. Disconnect air from tool. If piston (206129) moves from
“
A
”
dimension towards dimension
“
B
”:
Repeat steps 10
-
15.
If piston (206129) does not move from dimension
“
A
”
towards dimension
“
B
”:
Use a pair of calipers to check tool for full stroke
(.500”) (12.7
mm) using instructions
“
a
”
thru
“
c
”
below and diagrams on next page.
a. With the actuator assembly
-
air (704130) released, check dimension
“
A
”.
b. While holding actuator assembly
-
air (704130) in, check dimension
“
B
”.
c. Add dimension
“
A
”
to dimension
“
B
”.
If stroke is not consistent within
1/64” (.396
mm) follow bleeding procedure instructions again.
For your consideration, Gage Bilt offers a depth gage (Pt.# A
-
1935) to help simplify and more accurately check your tool stroke.
