Regular daily cleaning of the suction air
¿
lters is the
most important maintenance measure. The
¿
lter is of
two-stage type. At the front there is a course mesh
¿
lter
in a frame. Behind it there is a
¿
ne
¿
lter, a replaceable
paper element. To remove the side
¿
lter, unscrew screw
A and slacken screw B,
¿
g. P65. To remove the back
¿
lter, turn the holder plate.
The best way to clean the
¿
lters is with compressed air.
The course mesh
¿
lter may be washed in washing-up
liquid, if necessary. The paper
¿
lter must be replaced
minimum once a year.
The condenser in the air conditioning equipment on the
back wall of the engine compartment must be cleaned
daily, if necessary, by blowing air into the cell from the
engine side. Any debris may be removed from the sieve
chamber by opening the chamber cover and bottom.
Take care not to damage the heating cell.
The evaporator and the heating cell as well as the air
channels and the fan shall be cleaned minimum once
a year, and in dusty conditions more often. This can be
best done using compressed air and
or a vacuum clean-
er through the cab sunroof.
Checking of the Liquid Level in the COOL-
ING SYSTEM
The check shall be conducted at the beginning of every
harvesting season. Coolant may seep gradually through
the shaft gaskets out of the system. This may occur par-
ticularly if the cooling system is unused for long periods.
Slight seeping is always normal.
The check is made by running the cooling system at full
capacity. Look through the small inspection window on
top of the drying cartridge,
¿
g. P66, to make sure there
are no gas bubbles, but liquid behind the window. The
incidence of gas bubbles is allowed only for a short
period after the compressor switches on. The dryer is
located in the engine compartment in the coolant hose
between the condenser and the cab.
Be very careful when making the check, as the engine
compartment guard must be opened and the engine
started. Beware of the running belt drives and fan blade
in particular.
If necessary, the re
¿
ll shall be done by
an authorised service outlet.
