Air Cleaner
IMPORTANT:
The air filter ensures the air entering the engine is clean. Dirty air will reduce engine
performance and life.
Operating conditions will determine how often the air filter will need to be changed. Changing the air
filter is recommended over cleaning it.
The service schedule recommendation for 50-hour intervals between air filter changes is based on
average operating conditions. If dusty conditions prevail, filter should be cleaned before each shift or
every 8 operating hours. Replacement intervals should be reduced as-well.
