4. Turn the pressure booster regulator knob clockwise
until the main roll air pressure gauge reaches 150
psi (1030 kPa).
5. Use the main roll air pressure control to set the air
pressure to the required level.
WARNING
The pressure booster cycles several times
during this process. Make sure that the main
roll pressure gauge does not exceed 150 psi
(1030 kPa) at any point. Pressures over
150 psi can damage the electric air valves.

Smaller chain tensioning adjustments on the ORCA-I
SP laminator are handled by the automatic and second-
ary chain tensioners; however, when installing a new
chain or when the chain tension is more seriously out
of adjustment, use the following procedure to adjust the
chain tension.
Tools required:
•
1
/
8
" hex wrench
•
3
/
16
" hex wrench
•
Screwdriver
To adjust the primary chain tension:
WARNING
1. Remove the drive side cabinet cover by removing
the screws with the
1
/
8
" hex wrench.
2. Move the automatic chain tensioner off the chain.
3. Loosen but do not remove all four motor mount
bolts using the
3
/
16
" hex wrench as shown in the
figure below. The motor should just move freely
within the slots.

4. Using a screwdriver, apply a small amount of
downward pressure on the motor by prying against
the inside of the side frame until there is ¼" to ½"
play in the chain.
5. Tighten the mounting bolts while maintaining the
downward pressure on the motor.
6. Move the automatic chain tensioner back onto the
chain.
7. Replace the cabinet cover and reapply power to the
laminator.
Remove power from the laminator and make
sure it cannot be reapplied while you are
performing this procedure. You could be severely
shocked, be electrocuted, or get your fingers
caught in the drive mechanisms.
