Replacing the filter mats
The filter mats must be checked at regular intervals. If the mats are too dirty to allow the air
supply to flow normally, they must be replaced.
Note
Filter mat replacement is only relevant for options M23, M43 and M54.
Not replacing contaminated filter mats can cause premature drive shutdown.
