WARNING / AVERTISSEMENT
corporelles.
●
Pour plus d'informations sur les piles et les déchets électriques, veuillez contacter votre service d'élimination des déchets
ménagers, votre bureau local ou régional de gestion des déchets ou votre point de vente.
Charger
●
Always follow the instructions in the user manual and on the label of the battery charger.
●
The charger should be handled with care.
●
High voltage in the charger! DO NOT disassemble or replace parts of the charger.
●
DO NOT connect the charger to the power outlet for a long time. Unplug from the power outlet when not charging.
Lubrication
Lubricate the chains about every two weeks with bicycle-specific chain lube.
Chain Tension and Adjustment
The correct chain tension: with 3.5 oz (100 g) pressure, there should be 0.6–1.0 in (15–25 mm) free play between the chains.
How to adjust:
Loosen the axle nut on both sides, then adjust the bolt. When the proper free play is achieved, tighten the axle nuts. Make sure
there is no abnormal noise and the wheels can turn freely.
Tightening torque: 12–14 N·m
Brakes and Friction Components
The drum brake needs to be adjusted by professional technicians. Only replace the friction components with the original spare
parts. Please contact Segway-Ninebot after-sales service for details.
Maintenance Schedule and Items
Regularly check the brakes, steering system, rims, etc. See the details below:
Use a torque wrench to check
the tightness of motor bolts,
crank arm bolts, pedals, chain
ring bolts, saddle bolts, seat
post bolts, stem bolts, handlebar
bolts, and all accessory
mounting bolts/screws. Refer to
the tightening torque table for
the correct torque value.
Clean the bike and inspect the
frame and components for
signs of wear such as cracks.
Check all bearing system
components: hubs, headset
and pedals. Adjust and/or
overhaul as needed.
Check safety-related
accessories: horn, headlight,
rear light, brake light,
reflectors.
Accelerate and decelerate to
check for jamming or noise.
Check for rear hub jamming,
jumping and make sure the
axles are correctly connected.
Clean the drivetrain (chain,
chain rings, sprockets).
Check for chain wear and
replace worn parts.
Check for chain ring wear and
replace worn parts.

As with all mechanical components, EPAC is subjected to wear and high stresses. Different materials and components may
react to wear or stress fatigue in different ways. If the design life of a component has been exceeded, it may suddenly fail,
possibly causing injuries to the rider. Any form of crack, scratches or change of coloring in highly stressed areas indicate that
the life of the component has been reached and it should be replaced.
Comme tous les composants mécaniques, l'EPAC est soumis à l'usure et à des contraintes élevées. Différents matériaux et
composants peuvent réagir à l'usure ou à la fatigue de différentes manières. Si la durée de vie nominale d'un composant a été
dépassée, il peut soudainement tomber en panne, causant éventuellement des blessures au cycliste. Toute forme de fissure,
de rayures ou de changement de coloration dans les zones fortement sollicitées indique que la durée de vie du composant a
été atteinte et qu'il doit être remplacé.
