OPERATION

Safety

Safety is always the primary concern. If you have not read the safety information at the front of this manual, do so now. Do not attempt operation of the machine until you fully understand this safety information.

General Precautions

1.Keep razor blades, knives, and all other sharp objects away from the chrome and silicone rollers. They are easily damaged and very expensive to replace.

CAUTION:

Insert shims to keep the laminating and pull rolls apart when the machine is not in use. Do not rely on the air supply. Prolonged contact can damage the rolls.

2.Harsh chemicals such as Toluene or MEK will destroy the silicone covering on the laminating rolls. The rolls should be cleaned daily following the procedure outlined in the Maintenance section of this manual.

CAUTION:

If silicone adhesives contact the top or bottom roll, remove it IMMEDIATELY using isopropyl alcohol. It will harden within an hour.

3.Do not allow liquid silicone adhesives to contact the top or bottom silicone roll. These materials will bond to the roll in much less than one hour. If some adhesive does get on the roll, wipe it off IMMEDIATELY using isopropyl alcohol.

4.The laminating rolls will develop flat spots if left in

contact with each other when not in use. Always insert the shims when shutting off the laminator. Do not rely on the air supply to keep the top roller in the raised position, as the air supply can fail at any time.

5.Use a 100-percent cotton terry cloth to remove

heat-activated laminating residue, while the rolls are hot. Follow this procedure every time heat-activated laminates are used.

WARNING:

1.Never place fingers or arms between the rollers, both main and pull, or in roller slots no matter what the operational status the machine is in.

2.It is vital that everyone working around the laminator rolls avoid wearing loose-fitting clothing, ties or dangling jewelry, which could be caught in the nip.

WARNING:

Extra caution must be used when operating the laminator with the provided foot switch. The foot switch acts as an “over-ride” to the photoelectric eye; i.e., it allows the rolls to continue operation even if the photoelectric eye detects an obstruction near the nip.

This function is necessary a) to allow initial hand- feeding of process materials to the rolls and b) to prevent damage to the process at the end of a sheet due to “curl-up” of the sheet end.

Operators are cautioned to use the foot switch for as short a time as practicable, and to exercise caution when doing so.
