Maintenance, cleaning and servicing
7.1
Periodic maintenance
Repairs must only be carried out by the manufacturer.
Cleaning the units and checking the liquid levels is the only periodic maintenance required. With
normal use, no further maintenance should be necessary. If required, the system can be returned to
the manufacturer for re-conditioning.
Fluids, which attack ABS, should be used with caution. Continual immersion of the
cover in such fluids will cause deterioration. Spillage’s should be wiped off
immediately.
