After every 100 hrs. of tractor operation, check the hydraulic
suspension system filter (1) and clean the filter element.
The maintenance method is to turn the cover at the back end of
the oil filter, take out the filter element, clean it with solvent
and blow it dry with compressed air.
Replace it with a new filter element when it is difficult to clean
or it is broken.

The interval for air filter maintenance should be based on
the dust conditions in which the tractor operates. When the
dust is heavy, service is recommended every 8 hrs.
When the air filter is blocked, a visual alarm on the filter
housing turns red, and the air filter must be serviced.
Every day, or when refueling, check the air filter to ensure
that all of the joints between the air filter and engine are well
sealed, including all of the hose joints and the air filter housing.
When replacing the filter element, remove the wing nut and washer and carefully remove the element from
the housing. Take care to prevent dust from falling into the filter housing. Use a clean, moist cloth to wipe the
inside of the filter housing and the used safety filter element surface prior to reinstalling the filter element.
Do not use compressed air to clean up the filter housing.
Repair any holes immediately and log the repair into the machine service and maintenance record.
Dispose of any damaged filters and replace with a new filter. Use the cover, washer and wing nut to tighten it
down. Ensure that the filter rubber washer is mounted between the wing nut and filter element, and that the
intake resistor is installed. Ensure that the end cover position and seat are aligned prior to putting on the end
cover and fastening the clamp ring or wing nut.
