10 Maintenance and repair
10.1 Cleaning and care
Penetrating dirt and fluids will cause faults!
Safe function is no longer ensured due to the ingress of dirt and liquids.
Always ensure absolute cleanliness when working at the valve.
Solvents and aggressive cleaning agents!
Aggressive cleaning agents may damage the seals and the surface of the valve and
let them age faster.
Never use solvents or aggressive cleaning agents.
Damage to the hydraulic system and seals!
A high-pressure washer's water pressure could damage the hydraulic system and
the seals of the valve. The water displaces the hydraulic fluid from the hydraulic
system and seals.
Do not use high-pressure washers for cleaning.
For cleaning and care of the valve, please observe the following:
Close all openings with appropriate protective caps/devices.
Ensure that all seals and caps of the plug-in connections are firmly attached so
that no humidity can penetrate the valve during cleaning.
Remove external coarse dirt and keep sensitive and important parts such as valve
Remove dust and dirt accumulations on the valve at regular intervals.
10.2 Inspection and maintenance
Uncontrolled machine movements!
Risk of injury due to maintenance work at an activated machine.
Unless expressly otherwise specified, switch off the machine using the main
switch, lock the switch and remove the key prior to performing any work.
The following inspection, testing and maintenance work is to be carried out
regularly. The intervals for the same have to be selected in a way - also dependent
on the operating conditions - that ensures that any deficiencies which have to
be anticipated are identified timely. The check must, however, at least be carried
out every three years from the date of manufacture of the valve. The date
of manufacture of the valve can be seen on the name plate, see chapter 5.1.1
"Information on the name plate and the valve solenoid housing".
