Six step easy replacement of excavator air filter:

 Step 1:

When the engine is not started, open the side door behind the cab and the end cover of the filter element, disassemble and clean the rubber vacuum valve at the lower cover of the air filter housing, check for wear on the sealing edge, and replace the valve if necessary.

Step 2:

Disassemble the outer air filter element, check if there is any damage to the filter element, and replace it promptly if there is any damage; Clean the outer filter element with high-pressure air from the inside out, taking care that the air pressure should not exceed 205 kPa (30 psi).

Step 3:

When disassembling and replacing the air inner filter element, please note that the inner filter is a disposable component and should not be cleaned or reused.

Step 4:

Clean the dust inside the shell with a damp cloth, and note that high-pressure air blowing is prohibited here.

Step 5:

Properly install the inner and outer air filter elements and the filter element end caps, ensuring that the arrow marks on the covers are facing upwards.

Step 6:

After cleaning the external filter 6 times or working for 2000 hours, the internal/external filter needs to be replaced once.

When working in harsh environments, it is necessary to adjust or shorten the maintenance cycle of the air filter according to the on-site situation. If necessary, an oil bath pre filter can be selected or installed to ensure the intake quality of the engine, and the oil inside the oil bath pre filter should be replaced every 250 hours.
