Suction Plates and Sealing Lips

Clean the sealing lips with compressed air and/or water jet once per week to remove any objects and dirt such as
sand, stone particles, dust etc. Clean slot in the sealing lip with a cloth and / or blow out with compressed air.
Damaged or worn sealing lips (cracks, holes, deformation) must be replaced immediately.
Use only cold solvent for cleaning the device. Do not use benzene or caustic liquids, since these will damage the
hoses.
