A. CHECKING AND CHARGING

THE BATTERY

The battery used in this vehicle is a VRLA
(Valve Regulated Lead Acid) battery, it has
been pre-filled with electrolyte at the facto-
ry so there is no need to add fluid at any
time.

1. Check:

Using a digital volt meter, the state of a
discharged VRLA (Valve Regulated
Lead Acid) battery can be checked by
measuring open-circuit voltage (the
voltage measured with the positive and
negative terminals being disconnect-
ed).

• Do not attempt boost charging under

any circumstances.

• Battery electrolyte is poisonous and

dangerous, causing severe burns,
etc. It contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
Antidote: External -Flush with water.
Internal-Drink large quantities of wa-
ter or milk. Follow with milk of magne-
sia, beaten egg, or vegetable oil. Call
physician immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes, etc.,
away. Ventilate when charging or us-
ing in enclosed space. Always shield
eyes when working near batteries.
KEEP OUT OF THE REACH OF CHIL-
DREN.

• If the voltage is lower than 12.8 V the

battery must be charged. If this is not
done, the life of the battery will be
shortened drastically. Refer to the
service manual for battery charging
instructions.

• Never remove the strip of caps, nor

add any water or electrolyte.

B. MEASURING THE TIRE

PRESSURE

1. Measure:

• tire pressure

Out of specification

→

Adjust.

• The tire pressure should only be

checked and regulated when the tire
temperature equals the ambient air
temperature.

• The tire pressure and the suspension

must be adjusted according to the to-
tal weight (including cargo, rider, pas-
senger, and accessories) and the
anticipated riding speed.

• Operation of an overloaded vehicle

could cause tire damage, an accident,
or an injury.
NEVER OVERLOAD THE VEHICLE.

C. CHECKING THE ENGINE OIL

LEVEL

1. Stand the vehicle on a level surface.

• Place the vehicle on a suitable stand.
• Make sure that the vehicle is upright.

2. Let the engine idle for a few minutes,

and then turn it off.

3. Check:

• engine oil level

The engine oil level should be between
the minimum level mark (a) and maxi-
mum level mark (b).
Below the minimum level mark

→

Add

the recommended engine oil to the
proper level.

Before checking the engine oil level, wait a
few minutes until the oil has settled.

• Engine oil also lubricates the clutch

and the wrong oil types or additives
could cause clutch slippage. There-
fore, do not add any chemical addi-
tives or use engine oils with a grade of
CD (c) or higher and do not use oils la-
beled "ENERGY CONSERVING II" (d).

• Do not allow foreign materials to enter

the crankcase.

4. Start the engine, warm it up for several

minutes, and then turn it off.

5. Check the engine oil level again.

Before checking the engine oil level, wait a
few minutes until the oil has settled.

D. CHECKING THE FINAL GEAR

OIL LEVEL

1. Stand the vehicle on a level surface.

• Place the vehicle on a suitable stand.
• Make sure that the vehicle is upright.

2. Check:

• final gear oil level
