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-clockwiseto 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.

Six Months1. 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 NeededChain 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.
