Oil change
Change engine oil after the first 5 hours of actual use or after the
first month of ownership. After that, replace after every 50 hours of
use or every 6 months of ownership.
Refill
Remove the oil filler cap and insert
1.16qt (1.1 liters)
of the
recommended
SAE10w-30 oil.
1.
Remove the oil filler cap and then use a tool to remove the drain
plug located under the engine to allow the oil to drain out.
Note:
If you remove the drain plug, then please tighten with a tool to keep the hexagonal shaft from
becoming loose.
2.
After draining the oil, use a tool to replace the drain plug to its original position before pouring new
oil in from the oil filler cap.
Note:
Drain plug torque (closed): 435lbf

3.
After lubricating with engine oil, tighten the oil filler cap securely by hand to keep it from becoming
loose.
Note:
If the oil filler cap and drain plug are loose, oil could leak out. Be sure to fasten them securely.

HST oil inspection, change, and refill
Note:
HST oil, also known as hydraulic fluid, plays an important role in converting engine power to
the drive. It works as a lubricant--preventing rust-- and as a coolant. However, insufficient or
improper maintence may cause driving problems.
Always use proper HST oil to replenish or replace the HST oil.
HST oil gets extremaly hot after the mowing. Please service the oil when the machine is coo
Inspection and replenish
Check the oil level in the HST oil tank visualy.
If the oil level is not in between the upper and lower gauge,
open the tank cap and replenish with HST oil.
Oil change
Change HST oil after the first 30 hours of actual use.
After that, change oil after every 200 hours of use or every 1 year
of ownership, whichever occurs first.
1.
Place the oil drain pan under the HST unit.
2.
Loosen the oil drain bolt at the bottom of the HST unit with
a 22mm wrench. Then drain the oil.
3.
Tighten the drain bolt. Open the oil tank cap and refill slowly
with 0.52qts. (0.5litter) of HST oil (ISO 46 hydraulic oil).
Do not spill
4.
Leave the machine off to release air until the oil level reaches the
middle of the oil tank. Then idle the engine for one minute to
remove air bubbles
5.
Drive the machine back and forth, so that the HST unit is operating and removing air bubbles.
If the air bubbles remain in the HST unit, the machine will vibrate and will not move smoothly.
Repeat this step until the machine moves smoothly.
6.
The HST oil level may change after the air bubbles are gone. Always keep the oil level
between the lower and upper levels when the oil is cold.
