Orca 80-99 Operation and Maintenance Manual
3. Loosen both pull roll air cylinder caps and spin them
to their fully up position.
4. Lower the upper pull roll and spin down the pull roll
air cylinder caps until they are finger tight and secure
them. The pull roll nip is now set.
Cylinder Up/Down Rate Adjustment:
If the upper laminating roll or upper pull roll moves up
or down unevenly, the cylinder flow controls need to be
adjusted.
Turn them clockwise to slow the up/down rate and
counter-clockwise to increase the up/down rate. To
correct for uneven motion, when the roll is going up,
adjust the flow controls at the top of the air cylinders.
To adjust for uneven lowering, set the air pressure on
the laminating roll regulator at 100 pounds per square
inch (PSI), 690 kPa, and make the necessary
adjustments to the flow controls on the bottom of the air
cylinders.

1. Lubrication:
Disconnect the power and air supply to the machine.
Then, remove the end panels.
Lubricate the bearings on the ends of each laminating
roll (two per roll) with a high temperature grade of
bearing grease, such as Lubriplate 930-2 or equivalent
from a standard grease gun. Also lubricate the flange
bearing on the bottom secondary drive roll (pull roller).
Lubricate by hand the slots that both the upper main
and pull rolls slide up and down in.
Complete the lubrication by wiping the entire length of
the chain with an oily rag. It is also important to note
that over-lubrication of bearings is a leading cause of
bearing failure. Close the side panels, and reconnect the
electrical power and air supply.
As Needed
Chain Tensioning:
1. Make sure that the machine has air only, no power,
and that the right (drive side) cabinet is open (see the
diagram on page 8-3).
2. Using a large adjustable wrench turn the appropriate
chain tensioner until the desired chain tension is
achieved. Make sure that the chain tension of each of
the three chains is fairly close. If not it might cause
stuttering in the feed of the laminator.
