Maintenance
3. Position the wires across the beam.
4. Fasten mounting plates; tighten screws.
5. Carefully clamp the beam in a bench vice.
6. Pull the wires as tightly as possible with a pair of pliers.
7. Secure the mounting plates with the screws.
NOTES
• Check the strip of fiber glass for damage and replace if necessary.
• Check the springs and replace if necessary.
• Using the seal beam without the springs may cause the sealing wires to break.
APPLYING TEFLON TAPE TO SEAL BEAM
1. Position the new Teflon tape on the seal beam and cut out the corners.
2. Remove the protective backing from the Teflon tape.
3. Apply the new tape to the seal beam; the tape has an adhesive strip on both sides.
4. Slide the seal beam onto the pins in the vacuum chamber (machines with transparent cover).
5. Slide the seal beam in the holder of the cover, tighten the mounting screws, and re-connect the wires
(machines with metal cover).
NOTE
• The Teflon tape must not adhere to the tension blocks.
REPLACING SILICONE RUBBER SEAL OF COUNTER BEAM
The rubber seal is clamped in the counter beam. Replace the counter beam seal as follows:
1. Pull the old rubber seal from the groove in the counter beam.
2. Clean the groove.
3. Evenly press the new rubber seal into the groove and make sure that it does not stick out at either end of
the counter beam.
RUBBER SEAL OF VACUUM CHAMBER COVER
To assure that the vacuum chamber is properly sealed, it is important that the rubber seal is in good condition
and is not damaged. Replace the cover seal as follows:
1. Copy the length of the original rubber seal.
2. Pull the original rubber seal from the groove.
3. Clean the groove.
4. Evenly press the rubber seal into the groove; position the ends of the seal tightly against each other to
prevent leakage.
STRUTS, DAMPERS AND SPRINGS
• Machines with transparent covers are equipped with gas struts to open the cover.
• Machines with metal covers are equipped with oil dampers and springs to open the cover.
• Have the struts, dampers and springs checked by your dealer once every 5 years and have them replaced
as necessary.
• Have the gas struts replaced if the lid no longer opens properly.
