5.9 ABSORBER SPRING SYSTEM MAINTENANCE
Maintenance of the absorber spring system involves periodical lubrication of the suspension
in locations indicated in table (5.4) and described in the Lubrication section and periodical
monitoring of the technical condition of absorber plates.
The surfaces between the absorber plates should be protected using silicone spray with
anticorrosion and lubrication properties. Do not allow a thick layer of dry mud to accumulate
on absorber plates.
5.10 STORAGE
After finishing work with trailer cleaned thoroughly and wash with water jet. In the event of
damage to the paint coat, clean rust and dust from damaged area, degrease and then paint
with undercoat and after it is dry paint with surface coat paint retaining colour uniformity and
even thickness of protective coating. Until the time of repainting the damaged place may be
covered with a thin layer of grease or anticorrosion preparation. Trailer should be kept in
closed or roofed building.
5.11 TRAILER PREPARATION FOR END OF SEASON
If the trailer will not be used for a long time, it is essential to protect it from adverse weather,
especially rust and accelerated tyre deterioration. During this time trailer must be unloaded.
Trailer and canvas cover should be very carefully washed and dried. While washing do not
direct a strong water or steam jet at information and warning stickers, hydraulic or pneumatic
cylinders, electrical equipment, and hydraulic and pneumatic systems. If possible, clean and
dry canvas cover should be stored unfolded and suspended, otherwise it should be carefully
rolled up without any creases.
Corroded areas should be protected as described above in previous subsection.
Tyres should undergo conservation maintenance at least twice a year using the appropriate
preparations designed for this purpose. Wheels and tyres should be previously carefully
washed and dried. During longer storage of unused trailer it is recommended that every 2 to
3 weeks the trailer may be moved a bit so that the place of contact of tyres with ground is
changed. So that tyres are not deformed and maintain proper geometry. Also tyre pressure
should be inspected from time to time, and if necessary pressure should be increased to
appropriate value.
