.. GBC4180 INTRODUCTION These instructions describe the use and function of two (2) laminators which, despite their varying widths, are similar in appearance and performance: MODELS FILM WIDTH GBC4120 12" (30 cm) GBC4180 18" (46 cm) GBC Laminators apply coated, transparent film to one but usually both sides of documents, photographs, or any sheet-like material. GBC laminating film consists of a polyester film coated one side with polyethylene-heat reactivatible adhesive. The film is applied by heat and pressure with the adhesive contacting the product to be laminated. In the process, the adhesive adheres to the product and the end result is a laminate whose appearance is enhanced and resistance to damage is greatly increased. Laminating Hints 1. Always run test samples before laminating valuable products or documents, to insure proper laminator performance. 2. Feed product to be laminated slowly and evenly into heat roll nip with machine running. Employ side guide. Once product is engaged by the heat rolls, it is committed. Make no attempt to alter product position while in motion except to hold it taut from trailing edge. Wrinkles in laminated product usually are caused by attempts to straighten •product which has already been engaged. 3. Do not force product between heat rolls. If product does not enter heat roll nip easily, it is probably too thick to laminate successfully. GBC laminators accept product up to 1 /16" (1.59 mm) thick without difficulty. 4. Once a product has been engaged by heat rolls, allow laminator to finish job without stopping; for a stop—even momentary—will leave a mark on the laminate. Be sure product ejects completely from rear of laminator and past tear-off blade. This ensures tear-off in the film web and not accidentally into the laminated product. 5. If laminator is turned on shortly after having been turned off and both indicator lights illuminate, wait two (2) minutes before operating the laminator. Laminator Operating Controls SEE FIG. 1 1. Connect power supply cord to a source of 110/120 VAC, 50-60 Hz, 10, 30 Amp. power. Export models require 220/240 VAC, 50 Hz, 10,15 Amp. power. 2. Depress PREHEAT button. The Red "ON" light will illuminate. The Amber "Ready” light illuminates in 3 to 5 minutes, indicating that the laminator is ready to operate. 3. Depress RUN button to laminate. 4. Depress PREHEAT button to stop laminator. 5. Depress OFF button to shut down machine completely. Red and Amber lights extinguish. If machine has not been previously loaded with film, allow machine to cool and proceed to load and thread film. 6. NOTE: Do not insert materials into laminator until Amber "Ready" light is illuminated. Caution: Laminator drive motor will operate if control switch “Run” button is depressed, even though Amber “Ready” light is not illuminated.

Use film rolls of identical width and similar diameter and center them in laminator. The shiny side of regular film must contact heat rolls. The dull side of the film contains heat-reactivatable polyethylene adhesive. Use care when installing delustered film, since both sides appear similar. GBC film rolls always contain adhesive wound on the inside. 1. Release cam locks and raise interlock safety shield. Then remove feed table. 2. Remove top and bottom film supply shafts from laminator. 3. Remove the loose, right side discs from film supply shafts. Depending upon width of film rolls, readjust left side discs with alien wrench supplied with laminator. 4. Slide film rolls onto right ends of film supply shafts. A. Position film on top shaft with film unrolling from bottom towards operator. B. Position film on bottom shaft with film unrolling from bottom and away from operator. 5. Replace side discs on supply shafts and press firmly into film cores until both left and right side discs are flush with film rolls, 6. Install loaded film supply shafts into laminator by inserting left ends into mounting socket and seating right ends into mounting bracket slots. Make sure film unrolls properly. 7. Unroll film from top roll and drape over top film guide and both heat rolls. Unroll film from bottom roll and drape against both heat rollers. Insert a thin sheet of cardboard against the overlapping films and into heat roll nip. Turn threading knob clockwise until cardboard has entered heat roll nijb. 8. Install feed table and lower interlock safety shield, and rotate cam locks into position. 9. Depress PREHEAT button. Red “ON” light will illuminate. Amber "Ready” light illuminates in 3-5 minutes, indicating laminator is ...
