Weekly maintenance:
• Tightening of the main cylinder bolts;
• Clean the trailer regularly with sponge and soap;
• When cleaning never use hot water under high pressure, it will remove the grease from
bearings;
• Check the operation of the device;
• Check hydraulic pressure;
• Check the brake condition;
• Check wheel nut tightness;
• Check the bolts connecting the drawbar;
• Check the lights, reectors and lamps.
Monthly maintenance:
• Check the air pressure in tires;
• Check if there is enough lubricant on glide surfaces;
• Clean and lubricate hydraulic cylinders;
• Check hydraulic hoses for damages.
Yearly maintenance:
The towing eyelet needs to be changed at least once a year under normal operating conditions. It is
up to the user of the trailer to ensure that this is done.
Maintenance of the hydraulic units:
• Clean and lubricate piston rods of hydraulic cylinders;
• Check the hydraulic valves: Visually check the hydraulic valves. In case of leaking replace the
damaged valve;
• Check hydraulic hoses: Visually check the hydraulic hoses and pipe connections. Replace a hose
in case of leaking or if there are ruptures or slashes on it;
• Check the oil level, add and replace oil if trailer is equipped with pump and oil tank set. If not
then please check tractor oil level;
• Check the operation of the device;
When replacing hydraulic components such as hoses, gaskets etc, make sure they correspond with
original parts. To avoid malfunctions and ensure safe operation use original spare parts.
Changing the seals
Change all the cylinder seals at the same time. The piston cannot be split. The seals must be slipped over
the piston edge. Be careful not to break the seals when tting them in place!
