PREOPERATING CHECKLIST
Before operating the mower for the first time, and as
a routine before daily operations, it is important to
make sure the mower is properly prepared and
ready for operation. The following is a list of items to
be checked. (For a mower with frequent operation,
some of these items will not need to be checked ev-
ery day, but the operator should be aware of the con-
dition of each.)
For proper fuels and lubricants refer to Specifica-
tions.
FILL FUEL TANK
Fill the fuel tank using clean, fresh automotive grade
unleaded gasoline (87 octane rating minimum).
IMPORTANT: DO NOT permit dirt or other foreign
matter to enter the fuel tank. Wipe dirt from around
the filler cap before removing. Use a clean fuel stor-
age container and funnel.
IMPORTANT: DO NOT mix oil with gasoline. Al-
ways use fresh, automotive grade gasoline. DO
NOT use premium, white, or high-test gasoline. DO
NOT use additives, such as carburetor cleaners, de-
icers, or moisture removing agents. DO NOT use
gasoline blended with methyl alcohol.
