the converter increasing sharply the temperature inside it and in its turn it
will cause appearing of cracks in its ceramic block.
During the operation the converter becomes very hot. Therefore when park
ing the vehicle be sure that there is no combustible material (dry grass, wiping
waste, chip etc.) under the converter.
Never start the engine by towing the vehicle to prevent damaging of the
converter.
When starting cold engine (ZMZ4063) it is necessary to step on the ac
celerator pedal, close the choke and release the accelerator pedal. On violating
of the above stated sequence the carburetor choke rod possibly be broken.
To prevent damaging of the gearbox when towing the vehicle by its par
tial loading, disconnect the propeller shaft flange from the axle drive. Then fix
reliably the disconnected end of the propeller shaft via a wooden block to the
bracket crossbar of parking brake system linkage cable equalizer arm.
On the vehicles with ZMZ40522 engine fuel tank contacts with atmos
phere by means of gasoline vapour recovery system (mounted on some of the
vehicles). It consists of steam pipes and valves such as safety valve and pres
surevacuum control valve, as well as adsorber (adsorbs gasoline vapour) with
electromagnetic valve of blowing.
To avoid fire dangerous situation and damaging of the adsorber when fuel
gets into it, fuel tank design insures fuel cutoff during fuelling. Forced filling
of extra fuel is not allowed.
