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
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:
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
instructions in the
Op-
erating Instructions.
DANGER
Handle diesel fuel with care. Use safe
refueling 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 removing. Use a clean fuel
storage container and funnel.
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 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
ev-
ery 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 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
CHECKING/SERVICING
the
Engine
Cooling System
in
Maintenance Instructions.
WARNING
DO NOT remove the radiator pressure cap
when engine is hot.
CHECK HYDROSTATIC TRANSAXLE OIL
LEVEL
Refer to
LUBRICATION
for
Transaxle Lubrication
in
Maintenance Instructions
.
CHECK SECURITY OF DRIVE TIRE MOUNT-
ING NUTS
The eight (8) Drive Tire mounting nuts should each
be torqued to 75 to 85 ft-lbs. (102 to 115 N
·
m).
INSPECT FIVE (5) DRIVE BELTS
Engine Alternator, PTO (3) and Ground Drive.
CHECK TIRE PRESSURE
Deck Caster Wheel = 20 PSI (137 kPa)
Drive =
15 PSI (103 kPa)
Rear =
20 PSI (137 kPa)
