10 Maintenance and repair
10.1 Cleaning and care
NOTICE
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.
▶
Observe the ignition temperature of the cleaning agent.
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, 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 coarse dirt and keep sensitive and important parts clean.
▶
Remove dust and dirt accumulations on the valve at regular intervals. Comply
with the max. admissible dust layer thickness according to EN 60079-14.
▶
Only clean the valve using a damp, non-linting cloth. Only use water and,
if necessary, a mild cleaning agent.
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 works.
