is below [MIN] limit, add fluid.

Inspecting
•
To obtain correct reading, check HST fluid level before starting, or wait until HST
fluid cools off sufficiently. Hot HST fluid expands in volume and does not provide
correct reading.
•
It is enough if oil level is on [MIN] when oil is sufficiently cool.
• Do not fill fluid more than [MAX] level. Fuluid may expand and overflow from the
tank.
• Oil to Use: Page 34.
• Oil Capacity: Page 34.
