Checking the Index length
Make sure the air is not connected to the machine before changing the
indexing length. The first step is to calculate the length of the index- which
is roughly 1
½
cell lengths. For example, if you are using a standard 512 cell
tray – the length of stroke is approx. 1”, and a standard 288 cell tray is
approx. 1
¼
”. It is not necessary to determine the exact length, but you
need to insure that the push bar clears the wall of the next cell. To adjust
the stroke length, pull the handle toward you and release to lock. Slide the
stroke to required length and push handle away to lock the handle in place.
Measure the gap between the end of the cycle bar and stop bracket to the
length that you determine to be 1
½
cell lengths.
To check the indexing length, manually slide the stroke to adjust assembly
forward and backward and note that the push bars index at least one full
cell, and no more than one cell. Do not be concerned if the push bar ends in
the center of the cell.
The next step is to adjust the indexing push bars. To do this, first line the
tray up so that the first cell is directly under the drop tube bar. Next, unlock
the indexing push bar on the right hand side of the machine and slide it
right or left, until the prongs of the push bar are up against the forward wall
of any cell. Once the right hand push bar is set, then offer the tray forward
(left) to the left hand push and repeat to adjust.
