The stroke setting is important for the proper operation of the machine. If this setting has changed,
the machine may over-travel and cause the cylinder to "bottom out". This continued condition will
eventually cause the starter overload to open. It can also cause the hydraulic oil to overheat and damage
hydraulic system components. A slight change in the stroke setting can result in inadequate stroke to
operate the tooling.
A check of the machine’s stroke setting is made at the punch station; SEE FIGURE 5 ON THE
FOLLOWING PAGE. Set the stroke control handles (A) out to their farthest position. Turn the
selector switch (G) to the START position and power the machine. Then place this switch in the
SHEAR position. Measure the distance from the top of the punch bolster to the bottom of the punch
ram. The distance should be 9-1/32 inches (229mm). Turn the selector switch to the PUNCH position
and measure the distance. The distance should be 6-25/32 inches (172mm).
These dimensions are are + or - 1/16 of
an inch (3mm).
IF THE STROKE IS OUT OF THESE LIMITS, THEN USE THE FOLLOWING PROCEDURE:
1.
Loosen the two mounting plate screws (D) that hold the mounting plate to the machine.
SEE FIGURE 5 ON THE FOLLOWING PAGE.
2.
Move the plate vertically, up or down. Moving the plate up will bring the distance down and a
movement down will bring the distance up.
3.
Tighten the screws and re-check the dimensions. Repeat, if needed.
