Change of Hydraulic Oil
Caution
Be careful with hot oil, which could cause
burns if it contacts your skin.
Important
When you change the hydraulic oil, be sure to
drain it into a bowl and discard it in
accordance with local laws and regulations.
Important
If the oil emulsifies or if it becomes even
slightly less transparent, change the oil
immediately.
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.

Follow the steps below to remove the old oil.
Start and run the engine to warm up the
oil.
On a level surface, lower the mower units,
and then stop the engine.

Remove the drain plug of the hydraulic
tank, and then drain the old oil into a
container.
Wind new sealing tape on the drain plug,
and then attach it to the hydraulic tank.

Remove the left tank cover.
Open the tank cap, and then pour new oil
from the fill port until the oil level reaches the
middle of the oil gauge on the hydraulic tank.
The hydraulic tank capacity is approximately
44.0 dm

Tighten the tank cap securely.
Start the engine, raise and lower the mower
units, and turn the steering wheel left and
right.
Move forward and reverse repeatedly
several times.
Lower 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.
