SH. Select the oil’s SAE viscosity grade

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils (5W-

30,10W-30, etc.) improve starting in cold
weather, these multi-viscosity oils will

result in increased oil consumption when
used above 32°F (0°C). Check your
engine oil level more frequently to avoid
possible engine damage from running low
on oil.
Change the oil after every 50 hours of
operation or at least once a year if the tiller

is not used for 50 hours in one year.

Check the crankcase oil level before

starting the engine and after each five (5)
hours of continuous use. Add SAE 30
motor oil or equivalent. Tighten oil filler
plug securely each time you check the oil
level.

TO CHANGE ENGINE OIL

Determine temperature range expected
before oil change. All oil must meet API

service classification SF, SG or SH.

• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove drain plug.

• Tip tiller forward to drain oil.

• After oil has drained completely, replace

oil drain plug and tighten securely.

• Remove oil filler plug. Be careful not to

allow dirt to enter the engine.

• Refill engine with oil. See “CHECK

ENGINE OIL LEVEL” in the Operation

section of this manual.

AIR CLEANER

twenty-five hours, more often if engine is

used in very dusty conditions.
