CHECKING/SERVICING
DANGER
To prevent accidental starting of the engine
when servicing or adjusting the machine,
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 exter-
nal inspection
and should be done without
“dis-
turbing”
the filtration components.
On a daily basis, visually inspect the external
condition of the engine air cleaner system. The
following items should be inspected:
1. Check the Briggs & Stratton air cleaner canis-
ter 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
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.
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.
