Operation 34. Clean generator
Clean the generator from dust and dirt.
Check and, if necessary, tighten the bolts
fastening the generator.
Check the tightening torque of the
generator terminals and other electrical
equipment (starter, battery switch, etc.)
Operation 35. Clean the cab heating and
ventilation system filter
Note: In wet conditions, such as in the
early morning hours before servicing the
filter do not switch on the fan, because
any water particles trapped in the filter
are difficult to remove.
• Raise the cab roof (1).
• Remove the two mounting bolts and
filter cover (2) together with the two filtering
elements (3).
Lightly shake the elements to remove
free dust particles from the filter.
ATTENTION! Be careful not to damage
the filter!
• Clean the filters with compressed air
under a pressure not exceeding 2 bar.
Hold the hose nozzle not closer than
300 mm from the filter in order not to
damage the PFE.
Direct the air jet through the filter in the
direction opposite to the normal flow as
indicated by the arrows marked on the filter
housing.
• Install the filter performing the
operations in the reverse order.
Note: When operating the tractor in
conditions of high dust exposure, clean
the filter more frequently.
