F-36 PRO Laminator Operation Manual Maintenance and Troubleshooting

 "  

 #$

Performing regular maintenance on the F-36 PRO Laminator is critical to the proper operation of the machine. A maintenance schedule and a section of pro- cedures for disassembling and reassembling the ser- viceable areas of the laminator are included in this section.

Table 4-1: Maintenance Schedule

Daily	•	Clean/adjust the thermocouples
	•	Clean the rolls
	• Inspect the electrical cord for dam-
		age
	• Inspect the footswitch cord for dam-
		age
Monthly	•	Adjust the nip
	• Check the chain tension
	• Inspect the area around the laminator
		for possible hazards (dust buildup,
		combustible items stored too close,
		etc.)
Every Six	•	Lubricate the grease fittings and
Months		chain
	• Check wire termination tightness

One of the most crucial adjustments to the F-36 PRO Laminator is positioning the thermocouples and mak- ing sure they are clean. There are two thermocouples that control the temperature of the main rolls. If a ther- mocouples loses contact with its roll, the roll can over- heat and be seriously damaged or can even start a fire. Therefore, it is absolutely critical that both thermocou- ples be clean and positioned properly before operating the laminator and it should become second nature to check their condition prior to applying power to the laminator.

Tools required:

•1/8" hex wrench

•80% isopropyl alcohol

•100% lint free paper or cotton terry cloth

CAUTION

ALWAYS CHECK THE POSITION AND CONDITION OF THE THERMOCOUPLES PRIOR TO OPERATION! The thermal junction of the thermocouples MUST make contact with the laminating rolls to maintain proper roll operating temperatures. The thermocouples must also be free of adhesive and dirt. The rolls can overheat and cause a fire or seriously damage the laminator.

WARNING

Do not attempt to adjust the position of the thermocouples if the rolls are hot. You can be seriously burned.

To adjust a thermocouple:

1.Locate the thermocouple to be adjusted using the illustration in Figure 4-3.

2.Remove the two screws securing the thermocouple to the laminator using the 1/8" hex wrench and take the thermocouple out.

3.Inspect the thermocouple. If there is any adhesive or dirt on the thermocouple gently clean it off with 80% isopropyl alcohol and a cotton terry cloth.

4.Grasp the aluminum base of the thermocouple on either side of the rivets to provide support as shown in Figure 4-1. Using your fingers, gently bend the thermocouple where the “guitar pick” sensor meets the aluminum base.
