NOTICE
Mixing hydraulic fluids!
Product can be damaged!
▶ Before installation, remove all fluids from the control block to prevent mixing
with the hydraulic fluid that is used in the machine.
▶ Observe the viscosity and cleanliness level specified in the
data sheet for hydraulic fluids.
▶ Mixture of different hydraulic fluids may damage the control block due
to chemical reactions and changes in properties.
▶ Ensure that the different hydraulic fluids are compatible according
to manufacturer's specifications.
Contamination of hydraulic fluid!
The cleanliness of the hydraulic fluid has a considerable impact on the service
life of the product. Contaminations of the hydraulic fluid may lead to premature
wear and malfunctions!
▶ Always ensure a work environment in the assembly location that is free from
dust and foreign substances to prevent foreign particles, e.g. welding beads
or metal cuttings, from entering the hydraulic lines and lead to wear and
malfunctions in the product. The control block must be installed in a clean
condition.
▶ Only use clean ports, hydraulic lines and assembled parts
(e.g. measuring devices).
▶ When plugging the ports, no contamination may ingress.
▶ Before commissioning, ensure that all hydraulic connections are tight and
that all seals and plugs of the plug-in connection are correctly installed and
undamaged to prevent fluids and foreign particles from ingressing the product.
▶ Filter the hydraulic fluids when filling the system with a suitable filter system
to minimize the solid particle contamination and water in the hydraulic
system.
Improper cleaning
Product can be damaged!
▶ Plug all openings with appropriate protective equipment to prevent cleaning
agents from entering the control block.
▶ Never use solvents or aggressive cleaning agents. Clean the control block
using only water and a mild cleaning agent if necessary.
▶ Do not direct the high-pressure cleaner to sensitive components, e.g. rubber
parts (bellows), electric connections (solenoids, sensors) and actuation
elements.
▶ Use fibre-free cleaning cloths for cleaning.
