Procedure 15a. Clean the Filter of the
Cab Ventilation and Heating System
ATTENTION:
Under the conditions of
high moisture of the environment, do not
switch off the fan before cleaning the fil-
ters, because it is difficult to remove dust
from the moist paper filtering element.
The filters of the ventilation system are
fitted on the both sides of the tractor cab.
To clean the filter of the cab ventila-
tion and heating system, proceed as fol-
lows:
- to gain access to the filter, use a
stand or small ladder;
- turn out two screws with plastic
heads (1) under the projecting edge of
the cab;
- remove the panel (2) and remove the
filter (3);
- shake dust out of the filter by slight
tapping so that not to damage the paper
filtering element;
- clean the filter using compressed air
under the pressure of not more than 0.1
MPa. The hose nozzle shall be held at
the distance of not less than 300 mm
from the filter to prevent the damage of
the paper filtering element. It is neces-
sary to direct the air flow through the fil-
ter in the direction opposite to the normal
air flowing shown by the arrows marked
on the filter.
ATTENTION: If the tractor is operated
under the heavy dustiness conditions,
clean the filter after every 8-10 hours of
operation, i.e. after every shift.
Procedure 15b. Checking the Tighten-
ing of the Bolts of the CAC Air Ducts
(BELARUS-1523.3/1523 В .3)
Check and tighten the bolts of the
clamps of the air CAC ducts as neces-
sary. The torque of tightening the said
bolts shall be 10 to 15 N∙m
ATTENTION:
After checking the tighten-
ing of the bolts of the clamps, it is neces-
sary to check all the intake duct connec-
tions for leak-tightness. To do this, it is
necessary to perform the inspection for
damages and loss of tightness of the
connections of all the air ducts and sili-
con branch pipes of the air cooling sys-
tem. Should any faults or damages be
revealed when performing the check, it
would be necessary to ascertain their
causes and take measures for eliminat-
ing them!
NEVER
operate the tractor with faulty
charge air cooling system!
