Service Update
Product information: Cleaning the air filter Based on field experience, we would like to stress the importance of regular cleaning of the air filter, especially for engines with exhaust gas aftertreatment (Tier4i, Tier4f). It was found in field applications that a heavily soiled or clogged air filter causes a rapid rise in soot load in the diesel particulate filter (DPF), making the automatic burnout process impossible or insufficient. Although the au tomatic regeneration system tries to start the burnout process if the DPF soot load is high, it is not able to per form the burnout process sufficiently due to lack of air (resulting from the clogged air filter), causing the soot load to increase even more rapidly.
NOTE
Damage caused by heavily soiled or clogged air filter. Damage to components of the exhaust gas aftertreatment, in particular of the DPF, and machine downtime may be the consequences. ü Air filter cleaning intervals are specified in the maintenance table. a) Clean the air filter regularly according to the maintenance table. b) Observe the DPF warnings on the control display! Never ignore the DPF warnings on the control display!
