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
Specifica
-
tions on page 3.
F
FILL FUEL TANKS
Fill the fuel tanks with clean, fresh fuel. Clean
diesel fuel is particularly important since con-
taminated fuel will damage the fuel injectors
and injection pump.
NOTE:
It may be necessary to use the fuel
pump primer to bleed (purge out air bubbles)
the diesel fuel injector system when initially
filling an empty tank. Refer to
Fuel Pump
Priming on page 30
for instructions
.
DANGER
Handle diesel fuel with care. Use safe refu-
eling procedures:
●
DO NOT fill fuel tanks 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 tanks; 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 tanks. Wipe
dirt from around the filler cap(s) before remov-
ing. Use a clean fuel storage container and
funnel.
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 50.
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 56.
F
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 fins
should be inspected and cleaned if there is
any buildup of dirt or debris. (Remove the
intake screen assembly to inspect and
clean.)
● Check the coolant levels in the radiator
and overflow tank. If additional coolant is
needed, refer to
Engine Cooling System
on page 62.
WARNING
DO NOT remove the radiator pressure cap
when engine is hot.
● Check operation of electric radiator fan by
turning ignition key to the
ON (RUN)
position.
