NOTE: Although multi-viscosity oils (6W-30, 10W-20, etc.
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
92°F (0°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the tiller
is not used for 25 hours in one year.
CAUTION: Petroleum solvents, such
as kerosene, are not to be usedtoclean
cartridge. They may cause deteriora-
tion of the cartridge. Do not off car-
tridge. Do not use pressurized air to
clean or dry cartridge.
