Review
The feeder is shipped to you with a high-tension spring in the gate
assembly. Certain types of product may demand that you change the
gate assembly from a high-tension setting to a low-tension setting (for
example, irregular shaped product). This works well for most products,
allows for tall stack height, and helps provide the best performance in
preventing doubles.
If you are feeding a product of irregular thickness, you should change
to low-tension. This provides the following benefits:
• Allows the gate assembly to adjust to the irregular thickness
among product pieces.
• Prevents marking on the product by the gate assembly.
• Prevents peeling back the top sheet of a multi-page product.
Procedure
To change the spring from a high to a low spring tension, follow these
steps:
1. Remove the gate assembly from gate plate (lift up on knob
and tip at slight angle to remove).
2. Remove the adjustment knob by turning counterclockwise
(Fig. A).
3. Lift the cylinder off of top of spring (Fig. B).
4. Turn the cylinder around so that the cylinder collar faces up
(Fig. C).
5. Place the cylinder on top of the spring.
6. Replace the adjustment knob (make about 8 revolutions of the
knob before reinstalling gate assembly on gate plate).

Excessive lowering of the gate assembly can
damage product or lead to premature wear of
the O-rings or feed belts.
When changing from a low-tension to high-
tension setting, you may have to adjust the
stack height downward to prevent feeding
problems.
Certain types of single-sheet product may
require even more tension than the high-
tension setting can provide. To increase
tension even further, place a washer between
the cylinder and spring.
