10.1 Cleaning and care
Solvents and aggressive cleaning agents!
Aggressive cleaning agents may damage the seals of the safety valve and accelerate
aging.
Never use solvents or aggressive cleaning agents.
f
Damage to the hydraulic system and seals!
The water pressure of a high-pressure washer may damage the hydraulic system
and the seals of the safety valve.
Do not use a high-pressure washer for cleaning.
f
For cleaning and care of the safety valve, observe the following:
Remove external coarse dirt and keep sensitive and important parts clean.
f
Only clean the safety valve using a damp, non-linting cloth. Only use water and a
f
mild cleaning agent, if necessary, to do so.
10.2 Inspection and maintenance
Dirt and foreign particles in the safety valve!
Penetrating dirt and foreign particles in the safety valve lead to wear and
malfunctions. Safe function of the safety valve is therefore no longer ensured.
During all works at the safety valve, provide for absolute cleanliness in order to
f
prevent foreign particles like e. g. welding beads or metal chips from getting into
the hydraulic lines.
Do not use linting fabric for cleaning.
f
Ensure that no cleaning agents are able to penetrate the hydraulic system.
f
Flush the hydraulic system if necessary. Replace the fluid filter or the hydraulic
f
fluid.
