Adjusting Rewind and Take-up Clutches 
 

1.  Remove plastic plug from cover.  

 

2.  Run motor until Phillips head screw is aligned with plug opening. 
 
3.   Tighten Phillips head screw so that the clutch slips just enough to prevent your release     
       liner from tearing. 
 
4.  Replace plug. 
 

Note:

  This is only to be done when the rewind or take-up mandrel does not have enough 

force to properly remove and take up the release liner. Or if the release liner is being torn 
you can reduce the clutch friction. 

 
Cleaning Rubber Rollers:
 

 
Excessive build-up of adhesive on the rollers may cause poor lamination quality and erratic film 
movement.  Use the following procedure to remove any adhesive from the laminating rollers. 

 
1. Turn the HEATED ROLLERS off and allow the laminator to cool.   
 
2. Cut the film where it comes off the top and bottom supply rolls.  Pull any film out of the 
laminator and away from the rollers.   
 
3. Carefully remove the feed table to access the rollers.  The feed table exposes hot and 
moving parts. 
 
4. Disconnect the power supply. 
 
5. Clean the exposed section of the rollers with a soft cloth dampened with an appropriate 
cleaning solution such as denatured alcohol. 
 
6.  Reconnect  the  power  supply  and  turn  the  FORWARD/REVERSE  switch  to  the 
FORWARD position.  Turn the MOTOR switch to the ON position momentarily to expose 
a new section of the rollers. 
 
7. Repeat steps 3-5 until the rollers are thoroughly clean. 
 
8. Allow the rollers to dry completely before rethreading the laminating film. 

 
 
Removing Wrap-A-Rounds:
 

 
Build-up on the rollers may cause a film wrap-around, especially when using thin film gauges.  
Follow the procedure below to remove wrap-a-rounds. 
 

1. Turn the HEATED ROLLERS OFF.  Allow the laminator to cool. 
 
2. Cut the film where it comes off the top and bottom supply rolls.
