Suction plates/sealing lips

•
Remove stuck objects and debris such as sand, stone particles, dust, etc. from sealing lips at least once a week.
•
Clean foam rubber with compressed air and/or water jet or soap water.
•
Replace damaged or worn suction plates immediately (cracks, holes, corrugation).
•
Always replace suction plates completely.
Tip:
Heating the screw union of the suction plate makes it easier to loosen.
Seal the suction plate connection again when screwing in.

Inspecting safety features

Inspect the safety features (see section 2.6) at the start of every shift (if the device is not operated continuously) or once
a week (if operated continuously).

Inspect flashing light

WARNING
Lift the sealing lip of the suction plate slightly when the vacuum is building to simulate a leak.
The vacuum shown on the gauge will decrease. The light flashes when the vacuum falls below -0.43 bar.
WARNING

Inspecting suction hoses and clamps

Check that all suction hoses and hose clamps are securely fastened, tighten if necessary.
