DDifficulty 3/5

A bus has hydraulic power steering with a reservoir and level marks. Should the driver check its fluid?

Correct answer

Yes, and check that the level is between the maximum and minimum marks.

Yes. Check the level using the manufacturer’s procedure and intervals, observing the marks applicable to the checking conditions. Do not fill the reservoir to overflowing or wait until the steering becomes heavy. Fluid loss or abnormal operation requires the system to be inspected.
