Hydraulics 

•

 

Before repair work on the hydraulics system, lower the machine to the 

ground, remove the pressure from the system, stop the engine, and 

remove the ignition key. 

•

 

Hydraulic connections must be cleaned thoroughly before connecting. 

When connecting the hydraulic hoses to the tractor’s hydraulics, ensure 

that the pressure has been removed from the hydraulic system. 

•

 

For hydraulic systems with built-in pilot-controlled check valves, it can be 

difficult to release the pressure completely. You should hold a cloth 

around the fitting/part that is being removed to catch any oil that may 

leak. 

•

 

After repairs on the hydraulic system, all air must be bled from the 

system. 

•

 

Check the hydraulic hoses regularly for defects such as tears, cracks, 

wear, or damage. Defective hoses must be replaced immediately. 

•

 

Avoid spilling oil on the ground. If this should happen, it should be 

collected and safely disposed of immediately. 

•

 

Clean hands thoroughly after skin contact with oil and grease. Change out 

of oil-soaked clothing immediately, as this can be harmful to the skin. 

•

 

Hydraulic oil that flows out under high pressure can penetrate the skin 

and cause serious injuries. Seek professional medical assistance 

immediately in the event of any injury. 

•

 

Do not use discs or flexible hoses as handles, as these are movable parts 

that do not provide secure support. 

Mounting 

•

 

When mounting, there is a risk of crushing. There must be no persons 

between the implement and the tractor or between parts being 

connected. 

•

 

Do not use rings or flexible hoses as handles, these are moving parts that 

do not provide a secure support. 

Maintenance and repair 

•

 

During all repair and maintenance work, the machine must be properly 

supported or unfolded, the tractor and machine must have brakes 

properly activated, the engine stopped and the keys removed. 

•

 

Oil, grease and filters must be disposed of in accordance with current 

environmental regulations.
