CLEANING
If a pressure washer is used on the ex-
posed working parts, avoid water on the
electrical parts and the engine cooling sys-
tem.

Engine Air Cleaner System

There are two main components in the engine air
cleaner system: a turbine precleaner and a
Donald son Radialseal™ air cleaner. Each compo-
nent is checked, cleaned and maintained on a
different schedule based on the filtering action
required. Each component is serviced as follows:

Turbine Precleaner

The turbine precleaner is mounted on a remote air
intake tube connected to the Donaldson air clean-
er. A spinning fan driven by the intake airflow
separates dust from the air, giving the initial stage
of air clean ing. Dust particles are exhausted
through a single small vent in the side of the hous-
ing. Since no dust is trapped, the precleaner oper-
ates without clean ing. The only maintenance
required is to check the operation of the internal
fan every 100 hours. Verify operation:
1. Loosen the hose clamp and remove the tur-
bine precleaner.
2. Reach into the intake and check that the fan is
spinning freely. Reinstall the precleaner.
If the fan is not spinning, service or replace the
precleaner as required.
