Check of level of liquid of system of hydrostrengthening of a wheel

 PERFORMANCE ORDER

1. Periodically check liquid level in system of hydrostrengthening of a wheel in order to avoid emergence of problems with management of the car, such as damage of the steering pump. Act as follows.

Do not hold a steering wheel turned against the stop in this or that party more than five seconds. It can put the steering pump out of action.

2. The tank of system of hydrostrengthening of a wheel is located in a motive compartment and has the unscrewing cover with the measuring probe which is built in in it.
3. Park the car on the flat platform and cock the parking brake.
4. Engine 112: Remove the left hose of absorption of air.

5. Turn to the left on 1/4 turns a cover (1) and take out the index of level (2).

6. At cold oil its level has to be between the marks "MIN" and "MAX" (3/4) of the index. Oil is considered cold if its temperature makes about +20 °C.
At warm oil (+80 °C) its level has to be between the marks "MIN" and "MAX" (5/6) of the index.
7. If necessary liquid level in the tank should be added. For addition of level use only new liquid as even the most insignificant impurity can lead to violation of work of hydraulic system.

If liquid level in the tank fell below a zone, the corresponding temperature of liquid, steering with the hydraulic amplifier of the steering mechanism needs to be checked in a specialized workshop as liquid loss takes place. In this case it is not enough to be limited only to addition of level of liquid.

8. Insert a cover with the index and turn.
9. Engine 112: Fix the left hose of absorption of air.
10. At the working engine turn a steering wheel several times from an emphasis against the stop. Thus air will be removed from system.
