6. Maintenance
6.1
Periodic maintenance and inspection
NOTE
As road conditions may vary from one country to another, and specific use of the trailer landing leg
may differ per haulier, the maintenance intervals given below are only indicative. The maintenance
tables differentiate between normal use (X) and frequent- or off road use (0).
On-road use is when a vehicle drives on roads with sealed and metalled surfaces (like concrete or
asphalt). Off-road use is when a vehicle is leaving the road with sealed and metalled surfaces (like a
gravel road), even if it is for a short period of time.
Frequent use is when the the landing legs are turned up and down more than once a day.
The specified maintenance intervals are reference values. They must be adhered to as minimum
values. External influences as a result of use or climatic conditions may make it necessary to shorten
these intervals.

Cleaning
The landing gear is cleaned along with the vehicle, no special cleaning is required. Do not aim high-pressure cleaner
directly at the area around the gear. After cleaning the vehicle with high-pressure, all lubrication points must be re-
lubricated.
Any loose stones and course dirt must be removed from the landing gear immediately.
After cleaning the vehicle with high-pressure, all lubrication points must be re-lubricated.
