HST (Hydrostatic Transmission) Fluid
• To obtain correct reading, check HST uid level before starting, or wait until HST
uid cools off sufciently. Hot HST uid expands in volume and does not provide
correct reading.
• When oil is sufficiently cooled and is at the [MIN] level, its amount is sufficient.
• Do not exceed beyond [MAX] level. HST fluid may expand and overflow.
• Change HST oil once a year or every 500 hours, whichever comes rst.
• Oil to use and capacity: Page 46.
NOTE
• HST is a very delicate mechanism, and contamination of ten-micron-order
particles can damage it. When it is necessary to work on an HST, work in a
clean and dust-free environment, and make sure dust or dirt do not enter its
circuit.
