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 Specications.
FILL FUEL TANK
Fill the fuel tank with clean, fresh fuel. Clean diesel
fuel is particularly important since contaminated fuel
will damage the fuel injectors and injection pump.
NOTE: An electric fuel pump makes it unnecessary
to bleed (purge out air bubbles) the diesel fuel injec-
tion system when initially fueling an empty fuel tank.
DANGER
Handle diesel fuel with care. Use safe refu-
eling procedures:
● DO NOT ll 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 overll the fuel tank; 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 tank. Wipe dirt from around
the ller cap before removing. Use a clean fuel stor-
age container and funnel.
CHECK ENGINE CRANKCASE OIL LEVEL
Check the engine crankcase oil level before use and
after each 5 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 lter 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 lter
paper element every 100 hours). For detailed
procedures, refer to CLEANING the Engine Air
Cleaner System in Maintenance Instructions.
CHECK ENGINE COOLING SYSTEM
● Check the radiator air intake screen to make
sure the screen is clean and free of obstruction.
Also, the radiator cooling ns should be in-
spected and cleaned if there is any buildup of
dirt or debris. (Remove the intake screen as-
sembly to inspect and clean.)
● Check the coolant levels in the radiator and
overow tank. If additional coolant is needed,
refer to CHECKING/SERVICING the Engine
Cooling System in Maintenance Instructions.
WARNING
DO NOT remove the radiator pressure cap
when engine is hot.
● Check operation of electric radiator fan by turn-
ing ignition key to the ON (RUN) position.
CHECK GEAR AXLE OIL LEVEL
Refer to LUBRICATION for Gear Axle Lubrication
in Maintenance Instructions.
INSPECT FIVE (5) BELTS
Engine PTO Drive, Jackshaft Drive, Hydrostatic
Ground Drive, Engine Alternator Belt, and GHS
Blower Drive (if equipped).
