The Reliant 1500 is shipped to you with a high-tension spring in the
gate assembly. This works well for most materials, allows for tall
stack height, and helps provide the best performance in preventing
doubles. However, certain types of material may demand that you
change the gate assembly from a high-tension setting to a low-ten-
sion setting (for example, irregular shaped material).
If you are feeding a material of irregular thickness, you should
change to low-tension. This provides the following benefits:
1) allows the gate assembly to adjust to the irregular thicknesses.
2) prevents marking on the material by the gate assembly.
3) prevents peeling back the top sheet of a multi-page item.
Procedure
To change the spring from a high to a low spring tension, follow
these steps:
1. Move the feeder back from the gate plate to allow working
clearance. To do so, loosen the two T-handle screws from
underside of feeder. You can save much realignment time if
you mark the current position on the back deck plate before
moving.
2. Remove the gate assembly from gate bracket assembly. To
do so, pull cylinder down with one hand, lift up on knob
with other, and tip at slight angle to remove.
3. Remove the adjustment knob by turning counter-clockwise
(Figure 18A). Then lift the cylinder off of top of spring
(Figure 18B).
4. Turn the cylinder around so that the cylinder collar faces up
(Figure 18C). Then place the cylinder on top of the spring.
5. Replace the adjustment knob (make about 8 revolutions of
the knob before reinstalling gate assembly on gate plate).
6. Return feeder to original position marked on back deck
plate and tighten T-handle screws.

IMPOR TANT
When changing from a low-tension to high-
tension setting, you may have to adjust the
stack height downward to prevent feeding
problems.
!
Excessive lowering of the gate assembly can
damage material lead and/or lead to premature
wear of the O-rings or feed belts.
NO TE
Certain types of single-sheet material may
require even more tension than the cylinder
reversible can provide. To increase tension
even further, place a high-tension washer
between the cylinder and spring.
