Air filter - check/clean/change
Open the side cover (page 155).
Open the clips (3) and remove the cover (4).
Pull the outer filter element (2) out of the air filter case (6) and
check it for dirt.
Clean the air filter case and cover without removing the inner
filter element (1). Remove the inner filter element only when re-
placing it.
Clean the dust valve (5).
Replace the outer filter element if it is damaged or too much
dust has accumulated on it.
The internal filter element must only be replaced by skilled personnel in the framework of the corresponding ser-
vice period.
For the replacement, pull the internal filter element out and immediately insert a new filter element.
Clean the outer filter element with compressed air (max. 5 bar)
from the inside out without damaging the filter element. Wear
eye protection for this service.
Insert the outer air filter element and the cover with the TOP
mark facing up. Then lock the braces.
Close the side cover.
Risk of engine damage!
The interior filter element (1) must remain installed while cleaning the air filter case (6). Otherwise,
particles of dirt could enter the air intake duct while cleaning and damage parts of the injection sys-
tem and engine.
Do not clean the filter element with fluids. Never operate the engine without the air filter elements.
Always wear eye protection when working with compressed air.
