Latch Pawl Adjustment
Figure 8-5 shows a latch extended until it is over-center. The latch pawl (2) is normally
installed with the top surface flush with the top surface of the pawl mount (1). With the
lance clamped down, the latch should not go over-center (fully extended). The latch pins
(3) should not be up against the ends of their slots.
If the latch does go over-center, the latch pins make a clicking noise when they hit the
ends of the slots.
To reduce latch travel and increase clamping force, loosen the Philips-head screw in the
pawl recess and move the pawl down one notch. This adjustment may also be required
with higher purge air pressures to increase the clamping force.To reduce clamping force,
the pawl can be moved up one notch. However, do not do so if this allows the latch to go
over-center when the lance is clamped down.
