Park the mower on level ground before filling fuel tank.
Clean the area around the fuel cap before removing the
cap. Remove the fuel cap slowly.
When threading the fuel cap onto the filler neck, tighten the
cap until it begins to click, then, continue to turn it until at
least three clicks are heard.
IMPORTANT: Do not overfill the fuel tank. The fuel tank
should be filled no higher than the bottom of the fill neck. The
fuel system is designed to leave room for the fuel to expand
with fuel temperature changes. Figure 4-3
Use regular unleaded gasoline with an octane rating of 87
or higher. Maximum of 10% ethanol (E10) in fuel. Fuels with
greater than 10% ethanol (such as E15, E20 and E85) voids
warranty. Fuels with greater than 10% ethanol are not
approved for use and such illegal use could cause equipment
failure and pose a fire hazard.
Refer to the Engine Owner’s Manual for additional fuel
specification requirements.
Fuel Evaporation System Filter
These mowers have a fuel evaporation system filter. This
filter must be checked and replaced every 100 hours or
annually whichever comes first. Figure

Engine Oil and Filter
Check engine oil daily and after every 4 hours of operation.
Mower must be on a level surface when checking oil. Refer to
engine manual and maintenance schedule for oil capacities.

Motor Oil is recommended.
Initial oil and filter service should be performed between 5
and 10 hours. Thereafter every 40 – 60 hours or annually,
whichever comes first. Condition of oil should be checked
often and more frequent service for units used in adverse
conditions may be required. Always use the engine
manufacturer recommended viscosity and API classification
of oil. Oils specially formulated for air cooled engines that
include zinc are recommended. Retain service records to
validate warranty.

If the engine has been running and is up to operating
temperature, allow the engine to cool before
changing the oil. Engine and engine oil will be very
hot, so be very careful when changing oil and wear
the appropriate protective gear to avoid being
burned or exposed to engine oil.
