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 opera-
tion, some of these items will not need to be checked
every day, but the operator should be aware of the
condition of each.)
For proper fuel and lubricants refer to
Specifications.
FILL FUEL TANK
Fill the fuel tank using clean, fresh automotive grade
unleaded
gasoline (87 octane minimum, 10% etha-
nol maximum).
DANGER
Handle gasoline with care. Gasoline is
highly flammable and its vapors are explo
-
sive. Use safe refueling procedures:
•
DO NOT fill fuel tank with the engine run
-
ning.
•
If the engine is hot, allow to cool before
refueling.
•
Use an approved fuel container.
•
Fuel the mower outdoors.
•
DO NOT smoke while refueling.
•
Avoid spilling fuel; use a funnel or spout.
•
DO NOT overfill the fuel tank; fill up to
about 1 in. (25 mm) below the top of tank.
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 unleaded gaso-
line.
DO NOT
use gasoline containing greater than
10% ethanol.
DO NOT
use additives, such as car-
buretor cleaners, deicers, or moisture removing
agents.
DO NOT
use gasoline blended with methyl
alcohol.
