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
Switch on the vacuum generator.
Place the lifting device on a workpiece with a dense, smooth surface and apply suction to load.
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.
Check airtightness
Carry out a leak test once a month.
1.
Position the suction plates on a dense and smooth surface, e.g. a metal sheet.
2.
Turn on the vacuum.
3.
Apply suction to the load but do not lift (see section 6.5).
