Peculiarities of Vehicle Operation
Automobile preparation for work
Before starting the work it is recommended to do preparatory work, that is connected with the
car control and filling up by the maintenance material.
In addition it is necessary to check:
– cooling fluid availability and it’s level in the surge tank and if necessary add it;
– oil level in the engine pan, in the gearbox, in the driving axels, in the steering booster
system and if it’s necessary add oil up to needed level;
– the belts tension of the water pump drive, of the generator, of the compressor and steering
pump;
– air pressure in the tires.
Cabin Lifting Rules
The cabin is dumped forward with the help of the cabin lifting. Before lifting the cabin it is
necessary to lift the front folding board and withdraw from the left side rail of the base the pump lever
of the cabin lift.
When the pump handle 1 of the cabin lift (Fig. 17) is fixed in the position “Lifting”, hydraulic
rams 6 influence over the catch gear knuckles and open them, after this with the help of the hydraulic
ram 5 the cabin is lifted. In order to lower the cabin it is necessary to set the handle 1 in the
“Lowering” position.
In transport position the pump valve handle should be only in the “Lowering” position.
In transport position the cabin is fixed by two catch gears, which are fastened on the lever of
the cab rear suspension on the left and on the right.
Catch gears are opened mechanically with the help of hydraulic rams 6, fixed on the catch
gears webs at the expense of liquid pressure, supplied by the pump 2.
Catch gears are closed mechanically when the cabin is going down under the influence of the
axes 2 over the pinchers (Fig. 18)
It is necessary to control the right position of the knuckle 1 and the pincher 3 when the catch
gear is opened.
