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).
Open-circuit voltage
12.8 V or higher
Charging time
Charging is not necessary
• 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 PRES-
SURE
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.
Basic weight:
With oil and full fuel tank
206 kg (454 lb)
Maximum load*
189 kg (417 lb)
Cold tire pressure
Up to 90 kg (198 lb) load*
Front

250 kPa (2.50 kgf/cm
, 36 psi)
Rear
2
290 kPa (2.90 kgf/cm
, 42 psi)
90 kg (198 lb)–Maximum load*
Front
2
250 kPa (2.50 kgf/cm
, 36 psi)
Rear
2
290 kPa (2.90 kgf/cm
, 42 psi)
High speed riding
Front
2
250 kPa (2.50 kgf/cm
, 36 psi)
Rear
2
290 kPa (2.90 kgf/cm
, 42 psi)
* Load is the total weight of cargo, rider,
passenger and accessories.
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.
-9-
Recommended engine oil type
YAMALUBE 4 (10W-40) or SAE 10W-
40, YAMALUBE 4 (20W-50) or SAE
20W-50
Recommended engine oil grade
API service SG type or higher, JASO
standard MA
Quantity
Without oil filter cartridge replacement
3.73 L (3.94 US qt, 3.28 Imp. qt)
• 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 COOLANT
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:
• coolant level
The coolant level should be between
the minimum level mark (a) and maxi-
mum level mark (b).
Below the minimum level mark → Add
b
the recommended coolant to the prop-
a
er level.
