10.1 Cleaning and care
NOTE
Bearing failure
Applying grease-dissolving substances to the bearing points, e.g., during cleaning,
leads to bearing failure. There is a risk of damage to property, and service life may
be reduced.
Keep degreasers or aggressive cleaning agents away from the bearings!
Only clean the product with a damp cloth.
Conveyor chain failure
Applying grease-dissolving substances to the chain, e.g., when cleaning, leads to
chain failure. There is a risk of damage to property.
Keep degreasers or corrosive cleaning agents away from the toothed belt!
