Operation 16. Clean filters of cab air conditioning and heating system
To clean the filter of the cab air conditioning and heating system, proceed as follows:
- lift the cab roof (1) (Fig. 8.4.10).
- unscrew the two mounting bolts and remove the filter cover (2) together with two filter
elements (3).
- gently shake the elements to remove loose dust particles from the filter, be careful not to
damage the filter.
- clean the filters using compressed air under a pressure of 0.2 MPa max. Hold the hose
nozzle no closer than 300 mm from the filter in order not to damage the paper filter element. Direct
air flow through the filter in the direction opposite to normal air flow as shown by arrows on the
filter.
- assemble the filter in reverse order, close the cab roof.
Attention: in wet conditions, such as in early morning hours, before serving the filter do not
operate the fan, as trapped moisture particles in the filter are difficult to remove!
Attention:
when operating the tractor in conditions of high dust, clean the filter more
frequently!
