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 lubrication, refer to
Specifica -
tions on page 3
.
F
FILL FUEL TANK
Fill the fuel tank using clean, fresh automotive
grade unleaded gasoline (87 octane mini-
mum, 10% ethanol 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
running.
● 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 storage container and funnel.
IMPORTANT: DO NOT mix oil with gaso-
line. Always use fresh, automotive grade
unleaded gasoline.
DO NOT
use gasoline
containing greater than 10% ethanol. DO
NOT use additives, such as carburetor clean-
ers, deicers, or moisture removing agents.
DO
NOT use gasoline blended with methyl alco-
hol.
F
CHECK ENGINE CRANKCASE OIL LEVEL
Check the engine crankcase oil level before
use and
after each 8 hours
of continuous
operation. Refer to
Checking Engine Crank-
case Oil Level on page 42
.
F
CHECK AND SERVICE ENGINE AIR CLEAN-
ER SYSTEM
● Check air filter restriction gauge to make
sure the yellow indicator disk is in the safe
operating (green) range.
● Check condition, cleanliness, and security
of the complete air cleaner system (inspect
air filter paper element every 100 hours ).
For detailed procedures, refer to Engine
Air Cleaner System on page 51 .
F
CHECK ENGINE COOLING SYSTEM
Check that the engine cooling air intake
screen is free of obstruction by grass clippings
or debris and clean if required. Also, cylinder
head cooling fins should be inspected and
cleaned if any build-up of debris is noted
[remove two (2) cylinder head access panels
to inspect and clean]. Refer to
Cylinder Head
Cooling Fins on page 50
for this procedure.
Check performance of the cooling system by
starting the engine, holding a hand adjacent to
the cylinder heads, and feeling the cooling
airflow.
DANGER
Make sure to keep hands clear of exhaust
pipe, muffler, and moving parts when
checking airflow.
F
CHECK SECURITY OF DRIVE TIRE MOUNT-
ING NUTS
The eight (8) Drive Tire mounting nuts should
each be torqued to 75 to 85 lb·ft (102 to 115
N·m).
F
INSPECT TWO (2) DRIVE BELTS
Engine/PTO and Ground Drive.
