Maintenance Instructions

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 Cummins/Fleetguard OptiAir™ air
cleaner canister for damage. Make sure the
cover is in place and the cover latch is secure
–do not run the engine without the air cleaner
cover in place and secure.
2. Inspect the air intake hose for cracks, nicks,
cuts, etc., and check the hose clamps for tight-
ness.

Battery

NOTE: For initial battery service during setup, refer
to Battery Service in Assembly Instructions.
IMPORTANT: Make sure battery is securely mount-
ed in the frame. A loose battery may cause damage
to the case resulting in acid leakage and severe
dam age to the machine. A hazard may be created
by damage to critical working parts and safety sys­
tems.
NOTE: Checking electrolyte level is not required if
equipped with a sealed, maintenance-free battery.

DANGER
CHECKING/SERVICING

Electrolyte Level

The battery electrolyte level should be checked af-
ter every 25 hours of operation. To check electro-
lyte level:
1. Remove battery cell filler caps.
2. Check the electrolyte level. If the level is below
the bottom of the vent well, fill with distilled wa-
ter to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
3. Replace filler caps.
IMPORTANT: DO NOT overfill the battery. Electro-
lyte will overflow through the vented caps onto parts
of the machine and WILL result in severe corrosion.

Cleaning the Terminals

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