WORKSHOP MANUAL
Safety measures for work on hydraulic circuits
• Before disassembly, make sure the hydraulic circuits are depressurized. Hydraulic oil leaking under pressure may damage your skin
and cause serious injury.
• Before disassembly, mark the parts, hoses and pipes.
• Do not put hydraulic pumps and motors into operation without oil.
• Work with hot oil may result in scalding.
• Do not heat the oil to temperatures above 160°C – the oil or its vapours may ignite.
• When removing hydraulic components, always blank o the hose ends and outlets of the components.
• Use lint-free cloth when wiping and cleaning hydraulic parts.
• When assembling parts, use hydraulic oil as aslip agent – not lubricating grease.
• Before installation, carefully clean the ttings and ush and blow compressed air through hoses and pipes.
• Only use new seals.
• Fill new aggregates with hydraulic oil before installation.
• After ahydraulic aggregate replacement, ush the hydraulic circuit and clean the hydraulic tank.
• Replace the oil lter cartridge.
• Fill the hydraulic circuit with clean oil of prescribed viscosity, only when the engine is o!
• Wipe any overowed oil.
• Check the connections for any leaks before the system pressurizes.
• Check all connections after nishing all work.
• Do not adjust safety valves.
• After nishing work, reinstall all protective elements.
Check after putting into operation
• Oil level in the hydraulic tank.
• Check the charge pressure of replaced hydraulic pumps and the pressure of safety valves.
• Perform the measurement at 40 °C (104 °F).
Safety measures for work on the fuel system
Petrol and diesel mixtures (winter fuel) are as ammable as petrol.
- Do not refuel in enclosed spaces.
- Wipe any overowed fuel.
- Do not smoke and do not use an open ame while working on the fuel system! There is arisk of re!
