Tips for proper maintenance

These lists refer to an average operation of the trailer with a maximum of 10,000 km driven per year:

After the first 50 km. Measure the tire air pressure and adjust it to the recommended level. Check that the wheel nuts are tight and tighten them if necessary.

Every 500 km or min. 1 time per month. Check that the wheel nuts are tight and tighten them if necessary.

Every 2000 km or every three months. Measure the tire air pressure and adjust it to the recommended level. Check the functionality of the entire braking system and the handbrake. Check the lighting system, reflectors and signs for damage, presence and functionality. The individual components are the plug, cable, taillights, the front, side and rear reflectors, the license plate and the license plate light. Replace defective lamps and illegible signs (e.g. warning stickers).

Every 5000 km or every 6 months.

tire wear, wheels
Check the aging condition of the tires (e.g. cracks, porous areas) and measure the tread depth of the tires in the center of the tyre. Check the rims for visible damage (concentricity, lateral run-out) and, if necessary, have the wheels replaced or repaired as an axle or as a pair.

Ball coupling, overrun device
Visually inspect for damage and check components for proper functioning and wear. Oil or lubricate the overrun device. Replace any defective bellows or fix them if they are loose. Clean the pull rod of the braking device and lightly grease it if necessary. Check the breakaway cable for presence and damage.

Jockey wheel/support feet
Check the jockey wheel and the support feet for function and stability and lubricate the components at moving points.

lubrication work
Lubricate the overrun device, if necessary the brake linkage, the jockey wheel, if necessary the hinges of the side walls and the superstructure. You should lubricate the ball coupling and oil it in the appropriate places.

mounting screws
Check that all fastening screws are tight (see tightening torque table in the operating instructions ). Pay particular attention to screw connections in the area of the chassis. Tighten loose connections immediately. If the screw connections are worn or corroded, have them replaced. If necessary, have loose riveted connections replaced with screw connections.

Lashing points, lashing equipment
Check lashing points (eyelets, rings, brackets) and lashing straps, chains, ropes for damage and presence and replace them if necessary.

winch
Oil the bearing bush and the drum hub and grease the ring gear, the thread on the crank and the idler pulley.

Hydraulic system (pump, hoses, cylinders, connections)
Check the functionality of the hydraulic system, check whether hydraulic oil is leaking and have the system repaired if necessary. Inspect hydraulic hoses for cracking, aging and wear. Clean and lubricate the hydraulic cylinder connection points.

battery
Carry out a visual inspection for external damage or leakage of battery acid. Charge weak batteries and have defective or old batteries replaced.

loading area/loader bridge
Carry out a visual inspection of the surface for damage / rust / oxidation. Thorough cleaning and care of the loading area (if required). Treat wooden floor with linseed oil / turpentine oil / wood stain (if required).

Superstructures (e.g. side walls, railing, side wall attachments, H-frame, tarpaulin / frame, cover, etc.)
Check for damage, cracks, deformation of the superstructure. Have defective / damaged components replaced / repaired. Check locks / hinges and grease if necessary. Check attached superstructures for tight fit and function.

After 10000 km or 6 months. workshop service. Take your trailer to your trailer dealership or another specialist workshop at least every six months or every 10,000 km.
