ACQUAINTANCE WITH TRACTOR
E123
COOLING THE CAB INTERIOR
QUICKLY
1. Move the heating valve control (A) to
the left-hand position.
2. Set the air circulation control in the
cab (D) to the position of inner re-
circulation.
3. Choose the desired fan speed (posi-
tions 1, 2, 3) by the fan switch (B).
4. Use the switch (C) to turn on the air-
conditioning.
5. Set outlets to desired angle to avoid
direct blowing to persons in the cab
(possible illness because of intensive
cooling of parts of persons bodies).

HEATING OR AIR-CONDITIONING
OPERATION DURING TRACTOR
OPERATION
With the inner air recirculation switched-
on, the inlet of fresh air is closed and it
comes to breathing-up of the cab space
by operators. This state can cause feel-
ings of tiredness.
Note: When working, set the control (D)
according to your individual requirements
to temperature in a position between (a)
and (b) so that the fan could suck the air
from outside of the cab through filters.
E125
IMMEDIATELY AFTER THE CAB
COOLING
Immediately after cooling the cab and
reduction of the inner temperature to de-
sired level we recommend:
− Switch over the air circulation control
(D) from position (b - air recirculation)
to position (a - outer air suction).
− Perform fluent regulation of air tem-
perature with switched-on air-
conditioning by means of half-opening
of the heating valve (A). During this
setting, air flowing into the cab from
vents is not dried so intensively.
− You can perform fluent regulation of air
temperature with switched-on air-
conditioning by decreasing the fan
output so that you switch over the con-
trol (B) to position 1 or 2.
