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 (744129), air piston assembly (744121) should be all the way down.
CAUTION:
When forcing piston rod assembly (745344) downward, with head cylinder (745366) removed, hydraulic oil will eject forcibly
from handle assembly (744129).

then disconnect air supply.
9.
For
“
RETURN
”
pressure only:
Attach air bleeder assembly to side hole of manifold
-

in an upright position.
10. Connect the tool to air supply and cycle tool ten times holding the actuator assembly
-
air (704130) down for 2
-

.
11. Disconnect air supply. Remove air bleeder assembly from side hole of manifold

o
-
seal (S572) from head cylinder (745366) side hole (marked #2) and attach air

”).
14. Disconnect air supply. Remove air bleeder assembly from side hole (marked #2) on head cylinder (745366) and replace button
head cap screw (402482) and stat
-
o
-
seal (S572). Torque to 35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not over tighten.
15. Connect air supply. Cycle tool five times and check stroke of
.620” (15.75
mm) using a thru c and diagrams below. We recommend using calipers.
a. With the actuator assembly
-
air (704130) released, check dimension (A).
b. While holding actuator assembly
-
air (704130) in, check dimension (B).
c. Subtract dimension (A) from dimension (B). If stroke is not consistent within 1/64" (.396 mm) repeat bleeding steps 2
-
15 until stroke met.
For your consideration, Gage Bilt offers a depth gage (Pt.# A
-
1935) to help simplify and more accurately check your tool stroke.
Please contact Gage Bilt for more information.
