The hydraulic power unit (HPU) will shut down when fluid drops
below the sight glass. Normally, it should be close to the top of the
sight glass.

Do not mix different brands of hydraulic fluid.
Mixing different brands of hydraulic fluid can contaminate your system.
Call MTS if you are not sure what brand of hydraulic fluid your system uses.

NOTE
Be sure the fluid you add is prefiltered since it may not be clean.
