Adjustment Procedures

February 20005-6

5-3. Temperature Adjustment

Note:

• To perform the following adjustments, it is necessary to remove the right-hand plastic side

cover first; see Section 4-3: Disassembly / Reassembly Plastic Side Covers.

• To measure the temperature of the top roller, it is necessary to have the interlocking bolts

of the top cover in the unlocked position; see Section 4-1: Opening / Closing the

Aluminium Top Cover.

Necessary tools: Infrared Temperature meter, small flat head screwdriver.

Approximate time: 30-60 minutes.

The top roller temperature should be set to 160°C, ± 4°C (320°F, ± 7.5°F).

Changing the temperature to a higher value (in case it is too low) goes faster than the other way

around, as the roller is heating up faster than it will cool down. Therefore it is necessary to open the

top cover if the roller has to cool down, and wait approx. 15 - 20 minutes to assure that the

temperature is well under the correct value.

1. Before taking a temperature measurement,

the top cover has to be closed for at least 5

minutes. To do the measurement: open the

top cover, and quickly measure the

temperature of the top side of the top roller;

close to the middle of the machine.

See figure 40.

2. Close the cover again.

3. To change the temperature setting, insert

the screwdriver in the trimpot as shown in

figure 41. Rotating clockwise increases the

temperature, counter clockwise rotation will

decrease the temperature.

4. A five-degree turn of the trimpot will

increase/decrease the temperature by

approximately 10°C (18°F).

5. Repeat the previous steps if the

temperature is not correct.

After this adjustment procedure, assemble the

right-hand cover again.

Note:

Please do not forget to lock the top cover, as the user of the machine is not

allowed to open it.
