Only clean, filtered oil specified in the lubrication chart should be poured into the power steering reservoir.
A paper filter is installed in the pump reservoir
The filter must be replaced every 40 thousand km.
The oil level is considered normal if it is between the marks stamped on the wall of the reservoir.
The oil is added to the upper mark on the reservoir.

When changing the oil, it is necessary to:
- - disconnect the longitudinal steering rod;
- - turn the steering wheel to the left until it stops;
- - remove the reservoir cap by unscrewing the wing nut;
- - open the drain hole by unscrewing the plug with magnet from the steering gear housing;
- - drain the oil into a pre-prepared container;
- - remove the remaining oil and paper filter from the pump reservoir;
- - pour 1 liter of fresh oil into the reservoir through a funnel with a mesh and drain it through the drain hole, turning the steering wheel until it stops;
- - install a new element and secure it with a clamping bar as shown in Figure 2;
- - with the steering wheel turned all the way to the left, pour fresh oil into the pump reservoir up to the upper mark and, turning the steering wheel all the way, add oil until at least 2.5 liters are poured into the system;
- - start the engine and, with the steering wheel idling, turn the steering wheel from lock to lock, holding it briefly in the extreme positions for 2-3 seconds, with a force of approximately 100 N, and add oil as needed up to the upper mark. Filling the oil and removing air from the system is considered complete when air stops escaping in the form of bubbles through the oil in the pump tank;
- - stop the engine and remove the pressure bar from the paper filter
- - install the tank cover with the spring and sealing gasket, rubber ring, washer and tighten with a wing nut. The wing nut should be tightened by hand.
