CUSTOMER RESPONSIBILITIES
A
Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent
accidental starting of engine.
Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Remove fuel from tank before tipping unit
for maintenance. Clean muffler area of all grass, dirt, and debris.
Do not touch hot muffler or cylinder fins as contact may cause burns.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SF, SG or SH. Select the oil’s SAE viscosity
grade according to your expected temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
FIG. 18
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 25 hours of operation or at least
once a year if the tiller is not used for 25 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 (See Figs. 18 and 19)
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.
Use a funnel to prevent oil spill on tiller, and 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 oilfillerpiug. Becarefulnottoallowdirtto enter

Refill engine with oil. See “CHECK ENGINE OIL
LEVEL” in the Operation section of this manual.
