With the engine off, fill the nutrient tank with liquid up to the upper level mark on the plastic pipe, which is installed on the tank cover stand. With the engine off, slowly turn the steering wheel from lock to lock several times to bleed air trapped in the hydraulic system, then add fluid to the reservoir. Repeat this operation until the liquid level in the nutrient tank begins to decrease.
Start the engine and observe the fluid level in the reservoir. It may be necessary to add fluid to the nutrient tank after starting the engine.
With the engine idling, slowly turn the steering wheel 2 to 3 times approximately 45°to the left or right of center. Then turn the steering wheel left and right from lock to lock. Do not delay the steering wheel in extreme positions, as this will maximize the pressure in the hydraulic system. Repeat this operation until no more air bubbles appear in the nutrient tank.
If a noise is heard in the power steering system when the wheel is turned, this indicates that there is still air in the system. You can check this by setting the steering wheel to drive straight ahead and turning off the engine. If at the same time the liquid level in the nutrient tank increases, then there is air in the system and it must be removed.
After bleeding the hydraulic system, shut off the engine and let it cool down. After the engine has cooled down, check the fluid level in the reservoir and add fluid if necessary.
