Replace the Engine Air Filters
There are two engine air filters. The outer/primary and inner/secondary filters.
Open the compartment on the left-hand side of the excavator.
Pop open the clamps, remove the lid, and both filters.
Before installing the new filters, wipe out the inside of the filters’ housing with a clean cloth.
Install the New Air Filters
First, insert the inner filter by pressing it firmly.
Do the same with the outer filter. Press it until it bottoms.
We recommend removing the dust injector and cleaning the inside of the filter’s lid thoroughly.
Check the seal for damage before putting the lid back.
The cap has a top mark that should face upward — the dust ejector should be down.
Lastly, put the clamps back over.
