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 inch lbs. (3.95 Nm). Do not over tighten.
15.
Connect air supply. Cycle tool five times and check stroke of
.620” (15.75
mm) using instructions a thru c and diagrams below.
We recommend using calipers.
a. With the actuator lever assembly (704343) released, check dimension (A).
b. While holding actuator lever assembly (704343) 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.
