MEASURING THE STROKE
Feeder stroke can be easily measured with a stroke gauge. BF-4-ALF / ASLF Feeders leave the factory
with a correctly positioned metal stroke gauge attached to the side of the trough rib. Refer to Figure 6.
While the feeder is operating, the inner lines of the gauge appear as an X, and the stroke should be read
at the intersection of the X. Refer to Figure 7.
The position and quality of the individual stroke gauge may cause a variance of up to .010 inches (0.25
mm), which is acceptable.
