which offer increased compatibility with other fluids.
Rotate reservoir dust cover through ½ turn and fill reservoir approximately ¾ full with the
appropriate fluid. Rotate dust cover back to cover reservoir.

fluid during use. If the fluid becomes discolored, cloudy or particles appear in the reservoir,
the system should be drained and flushed with clean fluid.
