Safety instructions for work on hydraulic circuits
make sure that no hydraulic circuit is under pressure before dismantling it. Hydraulic oil leaks under pressure may injure your skin •
and cause a serious injury.
Mark all parts, hoses and pipes before removing them. •
Do not operate hydraulic generators and hydraulic motors without oil.
•
There is danger of being scalded when handling hot oil.
•
Do not warm oil to temperatures above 160 °C - oil or its fumes may ignite.
•
For cleaning and wiping hydraulic parts use such textiles that do not leave lint.
•
When reassembling parts use hydraulic oil - not grease - as lubricants.
•
Clean screws and bolts carefully before installation, wash hoses and pipes and blow them o using compressed air.

Fill new aggregates with hydraulic oil before installation.
•
Rinse hydraulic circuit after replacing the hydraulic device, clean the hydraulic tank as well.
•
Replace the oil lter cartridge.
•
Fill the hydraulic circuit with pure oil of the prescribed viscosity, but only when the engine has been stopped!
•
Wipe o overow oil.
•
Check connections for tightness, whether they leak oil, before applying pressure to the system.
•
Do not adjust safety valves.
•
After all work has been nished, recheck all connections and replace all safety elements
•
After nishing the work install again all protective elements.
•
After putting the machine into operation, check
Oil level in the hydraulic tank. •
Check up lling pressure in hydraulic generators in case they are replaced as well as pressure in safety valves.
•
Carry out the measurement at temperature of 40 °C (104 °F).
