Use Of Power Steering - Honda H6522 Owner's Manual

9. Use of power steering
The power steering system operates only when the engine is running.
Steering effort will increase when the engine is not running.
When you turn the wheel fully left or right, a relief valve will open to
relieve excess pressure. You will hear a high-pitched sound when this
happens. Avoid this condition for prolonged periods to prevent damage
to the steering system. Also avoid using excessive steering force when
the front tires are caught in a furrow or trench to prevent rim and tire
damage and possible tractor upset.
Do not make large movements of the steering wheel when the engine is
not running. Steering fluid will be forced from the system back to the
reservoir and may cause the reservoir to overflow.
