10 Maintenance and repair
10.1 Cleaning and care
NOTICE
Penetrating dirt and fluids will cause faults!
When dirt and fluids penetrate, safe function is no longer ensured.
▶
Always ensure absolute cleanliness when working at the valve.
Solvents and aggressive, highly inflammable 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 or highly inflammable 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 a high-pressure washer for cleaning.
For the cleaning and care of the valve, observe the following:
▶
Close all openings with appropriate protective caps/devices.
▶
Check that all seals and caps of the plug-in connections are firmly fitted so that
no humidity can penetrate the valve during cleaning.
▶
Remove external dirt and keep sensitive and important parts like valve solenoids
clean.
▶
Remove dust and dirt accumulations on the valve at regular intervals.
10.2 Inspection and maintenance
WARNING
Uncontrolled machine movements!
Risk of injury due to maintenance work at an activated machine.
▶
Unless expressly prescribed otherwise, deactivate the machine via the main
switch, lock it and remove the key before carrying out 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 that - also
depending on the operating conditions - expected deficiencies are identified in good
time. 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 found
on the name plate, see chapter 5.1.1 “Information on the name plate of the main
valve”.
