for maintenance. Clean muffler area of all grass, dirt, end debris.
Do not touch hot muffler or cylinder fins as contact may cause bums.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with API servica
classification SF, SG or SH. Select the oil's SAE viscosity
grade according to your expected temperature.

NOTE: Althoughmulti-viscosity oils (5W-30,10W-30, etc.)
improve starting in coldweather, these multi-viscosityoils
will result in increased oil consumption when used above
32°F (0°C). Check your engine oillevel more frequentlyto
avoid possible engine damage from runninglow on oil.
Change the oilafter every 25 hours ofoperation or at least
once a year ifthetractorisnot usedfor25 hoursinone year.
Check the crankcase oil level before starting the engine
and after each five (5) hours ofcontinuous use. Add SAE
30 motor oil or equivalent. Tighten oilfiller plug securely
each time you check the oil level.
TO CHANGE ENGINE OIL (See Figs. 16 and 17)
Determine temperature range expected before oilchange.
All oilmust meet API service classificationSF, SG or SH.
• Be sure tiller ison level surface.
• Oil will drain more freely when warm.
• Use a funnel to prevent spillon tiller,and catch oilina
suitable container.
