Hydraulic Oil Supply
Important
Do not mix different types of oil.
Important
Use Shell Tellus S2M46 (or equivalent) as
hydraulic oil.
In case of an equivalent, consult
Characteristics of Hydraulic Oil and use
hydraulic oil whose characteristics are
superior to those of the specific hydraulic oil.
Especially regarding kinematic viscosity and
viscosity index, use of hydraulic oil whose
figures are less than those of the specified
hydraulic oil will cause a malfunction in the
hydraulic circuit.

Start the engine, raise and lower the mower
units, and turn the steering wheel left and
right.
Move forward and reverse repeatedly
several times.
Raise the mower units and maintain that
position on a level surface, and then check
to see if the oil level is at the middle of the
oil gauge. If necessary, supply oil.
