Checking and Servicing

CHECKING/SERVICING

To prevent accidental starting of the en gine
when servicing or adjusting the ma chine,
remove the key from the ignition switch
and disconnect the spark plug wires.

Security of Air Filtration Components

NOTE: The following inspection is only an exter-
nal inspection and should be done without "dis-
turbing" the filtration components.
On a daily basis, visually inspect the external
condi tion of the complete air cleaner system. The
follow ing items should be inspected:
1. Check the Donaldson Radialseal™ air cleaner
canister for damage. Make sure the cover is
in place and the cover latches are secure—do
not run the engine without the air cleaner
cover in place and secure.
2. Inspect both air intake hoses for cracks, nicks,
cuts, etc., and check the hose clamps for
tight ness.
3. Check to make sure the air filter restriction
gauge is in place and hose connections are
secure.

Battery

The battery comes sealed and is maintenance-
free, so the electrolyte level will not need to be
checked or filled.
IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
severe damage to the machine. A hazard may be
created by damage to critical working parts and
safety systems.

DANGER
CAUTION
Important Battery Service, Installation, and
Charging Tips for Electronic Fuel Injection
Engines:
Do not allow the battery cables to touch
●
opposing terminals. When connecting
battery cables attach the positive (+)
cable to positive (+) battery terminal
first, followed by negative (-) cable to
negative (-) battery terminal.
Never start the engine when the cables
●
are loose or poorly connected to the
battery terminals.
● Never disconnect battery while engine
is running.
Never use a quick battery charger to
●
start the engine.
Never "jump start" the engine using an-
●
other source. Electricity fluctuations
can damage the ECU (Electronic Con-
trol Unit).
● Always disconnect negative (-) battery
cable lead before charging battery, and
also unplug harness from ECU before
performing any welding on equipment.

Cleaning the Terminals

If battery terminals are corroded, remove the
battery from the mower. Using a wire brush,
remove corro sion with a solution of one part bak-
ing soda and four parts water. Rinse with clean
water. Coat the terminals with petroleum jelly or
terminal protector spray to retard further corrosion.
