CAUTION:
Do not mix more than one type
of ethylene glycol antifreeze
containing corrosion inhibitors
for aluminum engine.
Do not use water containing
impurities or oil.
9. Install:
Radiator cap
Start the engine and warm it
up for a several minutes.
10. Check:
Coolant level
Coolant level low
→ Add cool-
ant.
Recommended coolant:
High quality ethylene
glycol anti-freeze con-
taining anti-corrosion
for aluminum engine

Au niveau spécifié.
ATTENTION:
Ne pas mélanger différents types
d’antigel à l’éthylène glycol conte-
nant un agent anticorrosion pour
moteurs en aluminium.
Ne pas utiliser de l’eau contenant
des impuretés ou de l’huile.
9. Monter:
Bouchon du radiateur
Mettre le moteur en marche et le
laisser chauffer pendant quelques
minutes.

CHECKING THE TAILLIGHT
(LEDs)
1. Disconnect the taillight coupler.
2. Connect two jumper leads
1
from the battery terminals to the
respective coupler terminal as
shown.
3. Check:
•LED (for proper operation)
Does not light
→ Replace the
taillight assembly.
WARNING
A wire that is used as a jumper
lead must have at least the same
capacity of the battery lead, oth-
erwise the jumper lead may
burn.
This check is likely to produce
sparks, therefore, make sure no
flammable gas or fluid is in the
vicinity. Battery (+) terminal →

CONTROLE DU FEU ARRIERE
(DEL)
1. Débrancher la fiche rapide du feu
arrière.
2. Brancher deux cavaliers 1 des bor-
nes de la batterie aux bornes corres-
pondantes de la fiche rapide,
comme illustré.
3. Contrôler:
LED (pour un bon fonctionne-
ment)
Ne s’allume pas → Remplacer le
feu arrière complet.
AVERTISSEMENT
Un cavalier doit avoir au moins la
même capacité qu’un câble de bat-
terie sinon il risque de brûler.
Ce contrôle est susceptible de pro-
duire des étincelles. Il convient donc
d’éloigner tout gaz ou liquide
inflammable. Borne (+) de la batterie →
