Squaring

In order for your machine to fold stock squarely, it must
be fed into the rollers square. Your Medalist has been
adjusted at the factory and should only require peri-
odic checks. The Medalist has a unique feed table ad-
justment feature to quickly and easily adjust it if needed.
WARNING: DISCONNECT THE POWER.
See power lockout procedure on page 6.

2. Loosely position the feed table side guides to the
scales on the feed table, (fig. 17 & 18). Read the front
scale at the inside edge of the side guide clamp block.
The rear scale will line up with the inside edge of the
side guide. The scales are set up to center the paper
on the sucker wheel. Initially set each side guide 1/4"
(6mm) wide. Do not tighten the lock knobs.

OPERATION

3. Raise the sheet separator (ccw) so it is away from
the sucker wheel (fig. 19). Place a sheet of the paper
to be folded on the feed table. Slide the sheet forward
into the rollers. The sheet must contact the rollers
evenly and not touch the side guides. Turn the hand
wheel so about 1/2" (3mm) is pulled into the rollers.
4. Position the operator side guide so it is just touching
the sheet but not pushing it. The side guide must be
even to the sheet from end to end. Tighten the front
lock knobs then the rear knobs, (fig. 17 & 18).
5. Repeat step 4 on the nonoperator side guide.
6. The paper will now feed square into the rollers. Now
that the side guides are square, the feed table squar-
Scale
ing screw, (fig. 17), can be adjusted for fine tuning the

Vacuum Feed Sheet Separator

The sheet separator will have to be adjusted for the
weight of stock you are folding. Ideal adjustment will
feed only one sheet without marking the paper or feed-
(fig. 17)
ing doubles. Use the following procedure to get started.
Fine tune these adjustments according to the condi-
tion of the paper and the environmental conditions of
your particular work area.
Adjustment procedure:
1. Raise the separator (ccw) to avoid marking the
sucker wheel.
NOTE: DO NOT MAKE SEPARATOR
