4. Turn the lock collar up several turns to allow the
upper pull roll to rest on the lower pull roll when
lowered.
5. Set the shim dial to zero (0).
6. Repeat steps 3-5 for the pull roll cylinder shaft on
the laminator's drive side.
7. Set the pull roll pressure to 40 psi.
8. Turn the UP-DOWN switch on the rear control
panel to the DOWN position to lower the upper
pull roll. Allow it to settle for approximately 10

WARNING
1. Before installing an incoming air supply that is
greater than 100 psi (700 kPa) and less than 120 psi
(825 kPa), close the pressure booster by gently
pulling out on the pressure booster regulator knob
and rotating it counterclockwise as far as possible.
See the figure below for the location of the knob.
Figure 4-3: Pressure Booster Adjustment
2. Pull out the main roll air pressure control knob and
rotate it fully clockwise.
3. Install the incoming air supply to the filter outside
the electrical end cabinet.
The nip area must be clear of obstructions before
you lower the upper pull roll to ensure that the
rolls contact properly.

If the air supply pressure exceeds the typical 100
psi (700 kPa), the pressure booster must be
adjusted when the air supply is installed to avoid
damage to the machine and possible injury to
service technicians.
Do not perform this adjustment if the air supply
pressure is the typical 100 psi.
Do not use an incoming air supply that exceeds
120 psi (825 kPa).
