PREOPERATING CHECKLIST
Before operating the mower for the rst 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 Specications.
FILL FUEL TANKS
Fill the fuel tanks using clean, fresh automotive
grade unleaded gasoline (87 octane minimum, 10%
ethanol maximum).
DANGER
Handle gasoline with care. Gasoline is high-
ly ammable and its vapors are explosive.
Use safe refueling procedures:
● DO NOT ll fuel tank(s) 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 overll the fuel tank(s); ll 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 tanks. Wipe dirt from around
the ller cap(s) before removing. Use a clean fuel
storage container and funnel.
IMPORTANT: DO NOT mix oil with gasoline.
Always use fresh, automotive grade unleaded gas
oline. DO NOT use gasoline containing greater than
10% ethanol. DO NOT use additives, such as
carburetor cleaners, deicers, or moisture removing
agents. DO NOT use gasoline blended with methyl
alcohol.
CHECK ENGINE CRANKCASE OIL LEVEL
Check the engine crankcase oil level before use and
after each 8 hours of continuous operation. Refer
to LUBRICATION for Checking Engine Crankcase
Oil Level in Maintenance Instructions.
CHECK AND SERVICE ENGINE AIR CLEAN
ER SYSTEM
Check condition, cleanliness, and security of the
complete air cleaner system (inspect air lter every
100 hours). For detailed procedures, refer to
CLEANING the Engine Air Cleaner System in
Maintenance Instructions.
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 ns
should be inspected and cleaned if any buildup of
debris is noted [remove two (2) cylinder head ac
cess panels to inspect and clean]. Refer to CLEAN-
ING the Cylinder Head Cooling Fins in Maintenance
Instructions.
Check performance of the cooling system by start
ing the engine, holding a hand adjacent to the cylin
der heads, and feeling the cooling airow.
DANGER
Make sure to keep hands clear of exhaust
pipe, mufer, and moving parts when
checking airow.
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).
INSPECT FIVE (5) DRIVE BELTS
Engine/PTO (3), Ground Drive (1) and Deck Drive (1).
