Kayoba JM20 MTB Traduction Des Instructions D'origine page 27

Follow the instructions below when
changing gear.
• Only change gear when the crank arms
and wheels are moving forward.
• Do not force the gears.
• Do not change gear while pressing down
hard on the pedals.
• Change gear in good time because you
must pedal forward when changing.
Change down to a lower gear before you
stop. This makes it easier to start cycling
again when you have a low gear. Change
gear in good time when you come to a
steep slope, so that you do not need to
change when pressing down hard on the
pedals.
• Do not pedal backwards while changing
gear.
BRAKES
The bike has rim brakes and two brake
handles, one for the front wheel and one for
the back. They are located on the two sides of
the handlebars. The right-hand brake handle
controls the front brake and the left-hand brake
handle controls the back brake.
WARNING!
Do not ride the bike if the brakes are not
working properly.
Safe braking
Brake a bit sooner with the back brake than
with the front brake and never brake with
the front brake when turning or on loose or
slippery surfaces.
MAINTENANCE
GENERAL
Clean the bike regularly for best lifespan
and functionality. Use a mild detergent and
avoid degreasing agents that can penetrate
the bearings and chain and interfere with
the lubrication. Store the bike in a dry place,
protected from direct sunlight.
CHAIN
Lubrication
The chain should be lubricated at regular
intervals. A dry chain wears more quickly, is
heavy going, and can rust.
1. Lubricate the chain with a suitable chain oil.
2. Pedal a few turns so that the oil gets into
the links.
3. Wipe the chain.
BRAKES
Adjusting
Adjust the play in the brake handle by turning
the adjusting screws (1) and (2). If the brakes
need larger adjustments, undo the screw (3)
a little so that the wire can be moved to the
required position in the fastener and then
screw tight.

Repairs
Replace worn or aged brake pads and brake
wires in good time. Go to a bike shop if in
doubt.
GEARS
All the moving parts of the gear system must
be kept clean and regularly lubricated for the
gears on the bike to function properly for a
long time. The derailleur should be lubricated
with molybdenum grease or the equivalent.
1. Smallest sprocket on the cassette
2. Upper adjusting screw
3. Roller
4. Largest sprocket on the cassette
5. Lower adjusting screw
