Manual Extract: Safety precautions during work on hydraulic circuits

– Check that hydraulic circuits have been depressurized before removing them. Hydraulic oil that leaks under pressure could cause serious skin injury.
– Mark parts, hoses and pipes before removing them.
– Do NOT operate hydroelectric generators or hydro motors with no oil.
– There is a scalding hazard when handling hot oil.
– Do NOT heat oil over 160°C (320°F) – oil or its vapors could flame up.
– Use lint-free cloth when wiping and cleaning hydraulic parts.
– Use hydraulic oil – not lube grease – as lubricating agent during parts installation work.
– Thoroughly clean the bolting before installation work; flush and blow out the hoses and pipes with air.
– It is important to ALWAYS use new gaskets.
– After hydraulic set replacement, flush the hydraulic circuit and clean the hydraulic tank.
– Replace the oil filter element.
– Fill the hydraulic circuit with clean oil of the specified viscosity – only with the engine switched off!
– Wipe up any spilled oil.
– Confirm that connections are tight with no oil leaks before pressurizing the system.
– Upon completion of all of the work, check all connections.
– Do NOT adjust the relief valves.
– Reinstall all protective elements after the work is completed
