SCOOTERS 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 SCOOTER.
HE OR SHE SHOULD:
●OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT SOURCE ON ALL ASPECTS OF SCOOTER 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 NECES-
SARY BY MECHANICAL CONDITIONS.
Safe riding
●Always make pre-operation checks. Careful checks may help prevent an accident.
●This scooter is designed to carry the operator only. No passengers.
●The failure of motorists to detect and recognize scooters in traffic is the predominating cause of automobile/scooter accidents. Many accidents have been caused by an automobile driver who did not see the scooter. Making yourself conspicuous appears to be very effective in reducing the chance of this type of accident.
●Therefore:
●Wear a brightly colored jacket.
●Use extra caution when approaching and passing through intersections, since intersections are the most likely places for scooter accidents to occur.
●Ride where other motorists can
1-1
see you. Avoid riding in another motorist’s blind spot.
●Many accidents involve inexperienced operators. In fact, many op-
erators who have been involved in |
1 |
|
|
accidents do not even have a cur- |
|
rent driver’s license. |
|
●Make sure that you are qualified and that you only lend your scooter to other qualified operators.
●Know your skills and limits. Staying within your limits may help you to avoid an accident.
●We recommend that you practice riding your scooter where there is no traffic until you have become thoroughly familiar with the scooter and all of its controls.
●Many accidents have been caused by error of the scooter operator. A typical error made by the operator is veering wide on a turn due to EXCESSIVE SPEED or undercornering (insufficient lean angle for
SAFETY INFORMATION
the speed).
● Always obey the speed limit and never travel faster than warranted by road and traffic conditions.
1 ● Always signal before turning or changing lanes. Make sure that other motorists can see you.
●The posture of the operator is important for proper control. The operator should keep both hands on the handlebar and both feet on the footboard during operation to maintain control of the scooter.
●Never ride under the influence of alcohol or other drugs.
●This scooter is designed for on-road use only. It is not suitable for off-road use.
Protective apparel
The majority of fatalities from scooter 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 could contribute to an impairment of vision that could delay seeing a hazard.
●The use of a jacket, substantial shoes, 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 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 scooter not approved by Yamaha, or the removal of original equipment, may render the scooter unsafe for use and may cause severe personal injury. Modifications may also make your scooter illegal to use.
Loading and accessories
Adding accessories or cargo to your scooter can adversely affect stability and handling if the weight distribution of the scooter is changed. To avoid the possibility of an accident, use extreme caution when adding cargo or accessories to your scooter. Use extra care when riding a scooter that has added cargo or accessories. Here are some general guidelines to follow if loading cargo or adding accessories to your scooter:
Loading
The total weight of the operator, accessories and cargo must not exceed the maximum load limit of 75 kg (165 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 scooter as possible. Make sure to distribute the weight as evenly as possible on both sides of the scooter to minimize imbalance or instability.
1-2
SAFETY INFORMATION
●Shifting weights can create a sudden imbalance. Make sure that accessories and cargo are securely attached to the scooter before riding. Check accessory mounts and cargo restraints frequently.
●Never attach any large or heavy items to the handlebar, front fork, or front fender. Such items can create unstable handling or a slow steering response.
Accessories
Genuine Yamaha accessories have been specifically designed for use on this scooter. 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 the following guidelines in mind, as well as those provided under “Loading” when mounting accessories.
●Never install accessories or carry cargo that would impair the perfor-
mance of your scooter. 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 scooter due to aerodynamic effects. Wind may attempt to lift the scooter, or the scooter may become unstable in cross winds. These accessories may also cause instability when passing or being passed by
large vehicles.
●Certain accessories can displace the operator from his or her normal riding position. This
improper position limits the free- |
1 |
|
|
dom of movement of the opera- |
|
tor 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 scooter’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 system when refueling.
●Never refuel while smoking or in the vicinity of an open flame.
1-3
SAFETY INFORMATION
●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
1consciousness and death within a short time. Always operate your scooter in an area that has adequate ventilation.
●Always turn the engine off before leaving the scooter unattended and remove the key from the main switch. When parking the scooter, note the following:
●The engine and exhaust system may be hot, therefore, park the scooter in a place where pedestrians or children are not likely to touch these hot areas.
●Do not park the scooter on a slope or soft ground, otherwise it may fall over.
●Do not park the scooter near a flammable source (e.g., a kerosene heater, or near an open flame), otherwise it could catch fire.
●If you should swallow any gasoline, inhale a lot of gasoline vapor, or allow gasoline to get in 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.
EAU10350
Further safe-riding points
●Make sure to signal clearly when making turns.
●Braking can be extremely difficult on a wet road. Avoid hard braking, because the scooter could slide. Apply the brakes slowly when stopping on a wet surface.
1-4
SAFETY INFORMATION
●Slow down as you approach a corner or turn. Once you have completed a turn, accelerate slowly.
●Be careful when passing parked cars. A driver might not see you and open a door in your path.
●Railroad crossings, streetcar rails, iron plates on road construction sites, and manhole covers become extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright, otherwise it could slide out from under you.
●The brake lining could get wet when you wash the scooter. After washing the scooter, check the brakes before riding.
●Always wear a helmet, gloves, trousers (tapered around the cuff and ankle so they do not flap), and a bright colored jacket.
●Do not carry too much luggage on the scooter. An overloaded scooter is unstable. Use a strong cord to secure any luggage to the carriers.
A loose load will affect the stability of the scooter and could divert your attention from the road. (See
page 1-1.)
