SAFETY INFORMATION
EAU10330
MACHINES ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND OPERATION ARE DEPENDENT UPON
THE USE OF PROPER RIDING
TECHNIQUES AS WELL AS THE EXPERTISE OF THE OPERATOR. EVERY OPERATOR SHOULD KNOW
THE FOLLOWING REQUIREMENTS
BEFORE RIDING THIS MACHINE.
HE OR SHE SHOULD:
●
OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
MACHINE OPERATION.
●
OBSERVE THE WARNINGS
AND MAINTENANCE REQUIREMENTS IN THE OWNER’S MANUAL.
●
OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.
●
OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDI-
TIONS.
Safe riding
●
Always make pre-operation
checks. Careful checks may help
prevent an accident.
●
This machine is designed for
off-road use only, therefore, it is illegal to operate it on public streets,
roads, or highways. Off-road use
on public lands may be illegal.
Please check local regulations before riding.
●
This machine is designed to carry
the operator only. No passengers.
●
Many accidents involve inexperienced operators.
●
Make sure that you are qualified
and that you only lend your machine to other qualified operators.
●
Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
●
Many accidents have been caused
by error of the machine operator. A
typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or undercornering (insufficient lean angle for
the speed). Never travel faster
than warranted by conditions.
●
Ride cautiously in unfamiliar areas. You may encounter hidden
obstacles that could cause an accident.
●
The posture of the operator is important for proper control. The operator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the machine.
●
Never ride under the influence of
alcohol or other drugs.
Protective apparel
The majority of fatalities from machine
accidents are the result of head injuries. The use of a safety helmet is the
single most critical factor in the prevention or reduction of head injuries.
●
Always wear an approved helmet.
●
Wear a face shield or goggles.
Wind in your unprotected eyes
1
1-1
SAFETY INFORMATION
could contribute to an impairment
of vision that could delay seeing a
hazard.
●
1
The use of a jacket, heavy boots,
trousers, gloves, etc., is effective in
preventing or reducing abrasions
or lacerations.
●
Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.
●
Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protective clothing that covers your legs,
ankles, and feet.
Modifications
Modifications made to this machine not
approved by Yamaha, or the removal of
original equipment, may render the machine unsafe for use and may cause
severe personal injury. Modifications
may also make your machine illegal to
use.
Loading and accessories
Adding accessories or cargo to your
machine can adversely affect stability
and handling if the weight distribution of
the machine is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accessories to your machine. Use extra care
when riding a machine that has added
cargo or accessories. Here are some
general guidelines to follow if loading
cargo or adding accessories to your
machine:
Loading
The total weight of the operator, accessories and cargo must not exceed the
maximum load limit of 90.0 kg (198 lb).
When loading within this weight limit,
keep the following in mind:
●
Cargo and accessory weight
should be kept as low and close to
the machine as possible. Make
sure to distribute the weight as
evenly as possible on both sides of
the machine to minimize imbalance or instability.
●
Shifting weights can create a sudden imbalance. Make sure that accessories and cargo are securely
attached to the machine before
riding. Check accessory mounts
and cargo restraints frequently.
●
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items, including such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this machine. Since Yamaha cannot
test all other accessories that may be
available, you must personally be responsible for the proper selection, installation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any accessories.
Keep these guidelines in mind for
mounting accessories in addition to
1-2
SAFETY INFORMATION
those provided under “Loading”.
●
Never install accessories or carry
cargo that would impair the performance of your machine. Carefully
inspect the accessory before using
it to make sure that it does not in
any way reduce ground clearance
or cornering clearance, limit suspension travel, steering travel or
control operation, or obscure lights
or reflectors.
●
Accessories fitted to the handlebar or the front fork area can
create instability due to improper
weight distribution or aerodynamic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.
●
Bulky or large accessories may
seriously affect the stability of
the machine due to aerodynamic effects. Wind may attempt to
lift the machine, or the machine
may become unstable in cross
winds.
●
Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the freedom of movement of the operator and may limit control ability,
therefore, such accessories are
not recommended.
●
Use caution when adding electrical accessories. If electrical accessories exceed the capacity of the
machine’s electrical system an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Gasoline and exhaust gas
●
GASOLINE IS HIGHLY FLAMMABLE:
●
Always turn the engine off when
refueling.
●
Take care not to spill any gasoline on the engine or exhaust
pipe(s)/muffler(s) when refueling.
●
Never refuel while smoking or in
the vicinity of an open flame.
●
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poisonous and may cause loss of
consciousness and death within a
short time. Always operate your
machine in an area that has adequate ventilation.
●
Always turn the engine off before
leaving the machine unattended
and remove the key from the main
switch. When parking the machine, note the following:
●
The engine and exhaust pipe(s)/
muffler(s) may be hot, therefore,
park the machine in a place
where pedestrians or children
are not likely to touch these hot
areas.
●
Do not park the machine on a
slope or soft ground, otherwise it
may fall over.
●
Do not park the machine near a
flammable source (e.g., a kerosene heater, or near an open
1
1-3
SAFETY INFORMATION
flame), otherwise it could catch
fire.
●
When transporting the machine in
1
another vehicle, make sure that it
is kept upright and that the fuel
cock(s) are turned to “ON” or
“RES” (for vacuum type)/“OFF”
(for manual type). If the machine
should lean over, gasoline may
leak out of the carburetor or fuel
tank.
●
If you should swallow any gasoline, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.

ECA11400
CAUTION:
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
knocking (or pinging) occurs, use a
3-4
gasoline of a different brand or premium unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
Gasohol
●
There are two types of gasohol:
gasohol containing ethanol and
that containing methanol. Gasohol
containing ethanol can be used if
the ethanol content does not ex-
ceed 10%. Gasohol containing
methanol is not recommended by
