When is it time to change the exhaust filter?

First, measure the filter pressure.

 If it exceeds 0.6 bar and the needle is in the red zone, filters must be changed.

 Also, if smoke is coming out of the exhaust, it is time for a filter change. 

With normal one-shift operation, filters should be changed at least annually.

It is best to use the manufacturer’s genuine exhaust filters, filter fleece and O-ring to complete the maintenance work.
