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 Cleaner System

NOTE: The following inspection is only an external
inspection and should be done without "dis-
turb ing" the filtration components.
On a daily basis, visually inspect the external condi­
tion of the engine air cleaner system. The follow­
ing items should be inspected:
1. Check the Briggs & Stratton 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 the air intake hose (into the engine) for
cracks, nicks, cuts, ect., and check the hose
clamps for tightness.

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.
NOTE: Checking electrolyte level is not required if
equipped with a sealed, maintenance­free battery.

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
another source.
tions can damage the ECU (Electronic
Control Unit).
● Always disconnect negative (-) battery
cable lead before charging battery, and
also unplug harness from ECU before
performing 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 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.
