Replacing the engine air cleaner
Important safety notes
! Only replace the engine air cleaner in a
low dust environment so that no dust can
enter the engine and cause damage.
! Do not clean the filter elements of the
engine air cleaner. Knocking, blowing out or
washing the filter medium could cause
structural changes and damage. The neces-
sary filtration grade of the filter element is
then no longer guaranteed. This results in
increased wear and tear and a reduced ser-
vice life for the engine. Replace the air filter
elements. Otherwise, you will lose your war-
ranty entitlements and you can damage
then engine.
