MAINTENANCE

Introduction

WARNING:

Some maintenance procedures require opening the cabinets while the power and air are still connected to the machine.

Because of the potential for electrical shock from wiring and crushing of fingers or arms in rotating apparatus, only properly trained personnel should perform these tasks.

CAUTION:

Never attempt maintenance on an operating machine unless the instructions specifically call for it.

GBC Pro-Tech laminators require minimal maintenance. However, regular maintenance is essential to keep any piece of precision machinery at peak performance. The following procedures are segmented into daily, monthly, biannual, and as-required procedures.

Daily1. Clean the Laminating Rolls:

The silicone laminating rolls can be cleaned of dust and dirt by passing an adhesive-coated board through the nip. (Of course, the nip should be set for the thickness of the board used). A mild dishwashing detergent can also be used to clean the rolls. However a better procedure is to use isopropyl alcohol and a 100- percent cotton terry rag.

Samples of these two items were supplied in the accessory kit shipped with the machine.

MonthlySetting the Nip:

The gap between the two laminator rolls and the secondary drive rollers is called the nip or roll nip. It should be checked once a month. They should be adjusted according to the following procedures.

Main Roll Nip Setting Procedure:

1.Make sure that the machine has both power and air. It is also necessary to make sure that the up/down rates of the upper main roll are even prior to setting the nip; if not follow the rate adjusting procedure on page 4-2.

Please note that the main rolls have to be cold (room temperature) when performing this procedure.

2.Remove the shims and set the main roll pressure to

40psi. Note that this must be done with the upper main roll in its fully up position.

3.Loosen main roll air cylinder caps and spin them to their fully up position.

4.Lower the upper main roll and spin down the main roll air cylinder caps until they are finger tight and secure.

5.Raise the upper main roll. The main roll nip is now set.Pull Roll Nip Setting Procedure:

1.Make sure that the machine has both power and air and that both cabinets are open. It is also necessary to make sure that the up/down rates of the upper pull roll are even prior to setting the nip; if not follow the rate adjusting procedure on the adjacent column.

2.Remove the shims and set the pull roll pressure to

40psi. The upper pull roll should be in the fully up position when making these adjustments.
