MAINTENANCE
In general, to insure the smooth operation of the leveling
system, it is a good idea to occasionally check the individual
leveling units to prevent problems. This is especially true
under the unusual conditions stated in the following:
If driving conditions are unusually muddy, the units may
become caked or clogged with mud. This condition may
hamper the proper operation of the leveling system. This
problem may be prevented or remedied by cleaning off each
leveling unit if they become excessively muddy.
In wet or icy weather leveling units may become encrusted
with ice. This may cause the leveling system to function
improperly. To eliminate this problem, periodically check the
leveling units and break loose any ice which may be causing
