CHECKING/SERVICING
DANGER
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 Cleaner System
NOTE: The following inspection is only an external
inspection and should be done without “disturb-
ing” the ltration components.
On a daily basis, visually inspect the external condi
tion of the engine air cleaner system. The following
item should be inspected:
1. Check the Kohler air cleaner canister for dam
age. Make sure both endcap covers are in
place and the cover latches are secure – do not
run the engine without the air cleaner cover(s)
in place and secure.
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
damage to the machine. A hazard may be created
by damage to critical working parts and safety sys
tems.
CAUTION
Important Battery Service, Installation, and
Charging Tips for Electronic Fuel Injected
Engines:
● Do not allow the battery cables to touch
opposing terminals. When connecting
battery cables attach the positive (+) cable
to positive (+) battery terminal rst, fol-
lowed by negative (-) cable to negative (-)
battery terminal.
● Never start the engine when the cables
are loose or poorly connected to the bat-
tery terminals.
● Never disconnect battery while engine
is running.
● Never use a quick battery charger to
start the engine.
● Never “jump start” the engine using
another source. Electricity uctuations
can damage the ECU (Electronic Control
Unit).
● Always disconnect negative (-) battery
cable lead before charging battery, and
also unplug harness from ECU before per-
forming any welding on equipment.
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 ller caps.
2. Check the electrolyte level. If the level is below
the bottom of the vent well, ll 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 ller caps.
IMPORTANT: DO NOT overll the battery. Electro
lyte will overow through the vented caps onto parts
of the machine and WILL result in severe corrosion.
