10 Maintenance and repair
10.1 Cleaning and care
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 oil 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 are firmly attached so that no humidity can penetrate the
valve during cleaning.
▶
Remove external dirt and keep sensitive and important parts clean.
▶
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 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 dependent 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".
