Each component ischecked, cleaned and maintained on a differentschedule based on the filtering action required.Each component is serviced as follows:Turbine PrecleanerThe turbine precleaner is mounted on a remote airintake tube connected to the Donaldson air cleaner.A spinning fan driven by the intake airflow separatesdust from the air, giving the initial stage of air clean-ing. Dust particles are exhausted through a singlesmall vent in the side of the housing. Since no dustis trapped, the precleaner operates without clean-ing. The only maintenance required is to check theoperation of the internal fan every 100 hours. Ver-ify operation:1. Look into the exhaust vent while shining a lightinto the intake.2. Start the engine and watch the fan begin to spinas the throttle is advanced.If the fan is not spinning, service or replace the pre-cleaner as required.Engine Air Cleaner System ComponentsAir IntakeHoseDonaldsonAir CleanerSafetyFilterAir CleanerCartridgeBrassElbowAirRestrictionGaugeVacuator™ValveHoseClampDonaldson AirCleaner CoverEngineTurbine PrecleanerPrecleaner Tube
