The air filter used in the intake system adopts tangential intake mode, and can handle very dirty air.
Operators should often remove dust particles accumulated in the dust exhaust valve of the rear cover of the air filter.
When the pressure difference indicator on the filter shows red, it indicates that the flow resistance of the air filter is too large, and the main filter element should be maintained or replaced in time.
In addition, the air filter is also equipped with a safety filter element, whose role is to play a temporary protection role in a short time in the case of damage to the main filter element.
The safety filter element does not need maintenance at ordinary times, only when the replacement of the main filter element and the main filter element replacement at the same time.
