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

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.
Ai! oil must meet AP! service classification SF-SJ.
•
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 oil filler plug. Be careful not to allow dirt to
enter the engine.
• Refillengine with oil.See“CHECKENGINEOILLEVEL’
in the Operation section of this manual.
AIR FILTER (See Fig. 20)
Yourengine will not run properly using adirtyairfilter. Clean
the foam pre-cleaner after every 25 hours of operation or
every season. Service paper cartridge every 100 hours of
operation or every season, whichever occurs first.
Service air cleaner more often under dusty conditions.
• Remove cover screw and cover.
TO SERVICE PRE-CLEANER
•
Remove foam pre-deaner from air cleaner cover.
• Wash it in liquid detergent and water.
