Maintenance
4.1 Hydraulics
After connection, the pressure of the hydraulic system is high. A fault under high pressure may cause the
hydraulic oil discharging from the system to penetrate the skin and cause severe injuries. The risk of injury
is also present when inspecting the system for leaks. In the event of injury, contact a doctor immediately
(risk of infection).
Use the necessary protective equipment and tools during maintenance. Exercise caution when performing
maintenance tasks. Check the hydraulic hoses at regular intervals and replace them if they are worn or
damaged. Only use spare parts that are supplied by the manufacturer or your retailer.
Take the following into account when replacing hoses:
•
Depressurise the hose before opening the connector.
•
The hoses must not be twisted or become twisted during the machine's operation.
•
Do not tighten the connector nut excessively.
•
Check the position of the connector.
•
Use correctly-sized hose ties.
•
Tighten the threaded (=male) connectors before tightening the connector nuts.
•
Use locking and sealing agents.
•
Use correctly-sized spanners.
Remove a hose and connector from use in the following cases:
•
The hose has come off the connector. (In this case, the connector must also be discarded.)
•
The hose has a tear or leak (also when the hose is moist due to internal seepage)
•
The surface layer has worn all the way down to the support weave
•
The hose has a permanently flattened or otherwise deformed section
•
The hose displays signs of burning or the surface is cracked
•
The hose manufacturer does not guarantee a life span exceeding five years
•
The connector has corroded or features a permanent deformity
•
The connector leaks
Note! The compression connector can only be used once
Protecting yourself from oil and grease
Oil and grease may contain additives that may, in some cases, be harmful upon repeated skin contact.
Adhere to the appropriate safety instructions when handling these substances.
•
When handling oil or grease, always use the appropriate protective clothing and oil-proof gloves, along
with protective hand creams.
•
Prevent oil from spreading into the working area or the environment. The spreading of oil mist in the
working area or the spilling of oil on pathways will cause a slipping hazard.
•
Prevent skin contact with oil or grease.
•
Never use oil or lubrication grease to clean your hands.
•
Oily clothes must be immediately replaced with clean ones.
•
Do not place oily cotton or similar items in your pockets.
•
Collect waste oil and dispose of it according to the appropriate regulations.
