Crank axle
Regularly check the crank axle
for play.
1. Regularly check the crank
axle for play.
2. You must not feel any play.
If there is some play on
the crank axle, it can
result in damage to the
frame.
Tightening the crank
axle requires special
tools. Leave this job up
to your Koga dealer.
Gears
The gears are used to shift the
gear ratio as desired.
Hub gears
The right lever operates the hub
gears.
Stop pedalling when
you change gears.
Setting the hub gear
requires experience
and special tools.
Leave this job up to
your Koga dealer.
Derailleur gears
The left lever operates the front
chain rings.
The right lever operates the back
chain rings.
Continue pedalling
lightly while you switch
gears, but do not apply
force to the pedals.
When switching gears,
never pedal backwards.
Never operate both
gear levers at the same
time.
Use gears in such a way that the
chain runs diagonally as little as
possible (1). A chain that runs at
too great an angle (2) will wear
excessively.
Maintenance
If gear shifting does not go
smoothly, have your Koga dealer
adjust your gears.
