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 every
day, but the operator should be aware of the condition
of each.)
For proper fuel and lubricants refer to Specifications.
FILL FUEL TANK(S)
Fill the fuel tank(s) using clean, fresh, automotive
grade unleaded gasoline (87 octane rating mini-
mum) or gasohol (up to 10% ethyl alcohol, 90%
unleaded gasoline by volume). See engine manual
for complete fuel recommendations.
IMPORTANT: DO NOT permit dirt or other foreign
matter to enter the fuel tanks. Wipe dirt from around
the filler 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 or gasohol. DO NOT use premium, white, or
high-test gasoline. 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 air restriction gauge to make sure there is
no red indication showing.
•
Check condition, cleanliness, and security of the
complete air cleaner system (inspect air filter
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 fins
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].
CHECK SECURITY OF DRIVE TIRE MOUNT-
ING NUTS
The eight (8) Drive Tire mounting nuts should each
be torqued to 75-85 ft-lbs. (101.7-115.2 N
· m).
INSPECT FOUR (4) DRIVE BELTS
Engine/PTO and Ground Drive.
CHECK HYDROSTATIC TRANSAXLE OIL
LEVEL
Refer to LUBRICATION for Transaxle Lubrication
in Maintenance Instructions.
CHECK TIRE PRESSURE
Deck Caster Wheel = 20 PSI (137 kPa)
Drive
= 15 PSI (103 kPa)
Rear = 20 PSI (137 kPa)
DANGER
Handle gasoline with care. Gasoline is high-
ly flammable and its vapors are explosive.
Use safe refueling procedures:
•
DO NOT fill 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 overfill the fuel tank(s); fill up to
about 1 in. (25 mm) below the top of tank.
