5. GASOLINE IS HIGHLY FLAMMABLE.
Always turn off the engine while refu-
eling. Take care to not spill any gaso-
line on the engine or exhaust system.
Never refuel in the vicinity of an open
flame, or while smoking.
6. GASOLINE CAN CAUSE INJURY.
If you should swallow some gasoline,
inhale excess gasoline vapors, or
allow any gasoline to get into your
eyes, contact a doctor immediately. If
any gasoline spills onto your skin or
clothing, immediately wash skin
areas with soap and water, and
change your clothes.
7. ONLY OPERATE THE MACHINE IN AN
AREA WITH ADEQUATE VENTILA-
TION.
Never start the engine or let it run for
any length of time in an enclosed
area. Exhaust fumes are poisonous.
These fumes contain carbon monox-
ide, which by itself is odorless and
colorless. Carbon monoxide is a dan-
gerous gas which can cause uncon-
sciousness or can be lethal.
8. PARK THE MACHINE CAREFULLY;
TURN OFF THE ENGINE.
Always turn off the engine if you are
going to leave the machine. Do not
park the machine on a slope or soft
ground as it may fall over.
9. THE ENGINE, EXHAUST PIPE, MUF-
FLER, AND OIL TANK WILL BE VERY
HOT AFTER THE ENGINE HAS BEEN
RUN.
Be careful not to touch them or to
allow any clothing item to contact
them during inspection or repair.
10. PROPERLY SECURE THE MACHINE
BEFORE TRANSPORTING IT.
When transporting the machine in
another vehicle, always be sure it is
properly secured and in an upright
position and that the fuel cock is in
the “OFF” position. Otherwise, fuel
may leak out of the carburetor or fuel
tank.

BATTERY INSPECTION AND CHARGING
Charging method using a variable voltage charger
Connect a charger and
ammeter to the battery
and start charging.
Is the amperage higher
than the standard charg-
ing amperage written on
the battery?NO YES Charger
Ammeter
Adjust the voltage to obtain
the standard charging amper-
age.
Set the timer to the charging
time determined by the open-
circuit voltage.
Refer to “BATTERY
INSPECTION AND CHARG-
ING” section.Adjust the charging voltage to
20 ~ 25 V.
Monitor the amperage for 3 ~
5 minutes. Is the standard
charging amperage exceeded?
NO YES
If the amperage does not
exceed the standard charg-
ing amperage after 5 minutes,
replace the battery.
If the required charging time exceeds 5 hours, it is advisable to check
the charging amperage after 5 hours. If there is any change in the
amperage, readjust the voltage to obtain the standard charging amper-
age.
Leave the battery unused for more than 30 minutes before measuring
its open-circuit voltage.
12.8 V
→ Charging is complete.
12.0 ~ 12.7 V
→ Recharging is required.
Under 12.0 V
→ Replace the battery.
Leave the battery unused for
more than 30 minutes before
measuring its open-circuit voltage.
Set the charging voltage to 16-
17 V. (If the charging voltage is
lower, charging will be insuffi-
cient, if it is higher, the battery will
be over-charged.) NOTE:
NOTE:
Measure the open-circuit
voltage prior to charging.
