Maintenance

6.1 To clean the product

● Clean the product regularly.
● Clean with a mild detergent. Do not use degreasing
products that can penetrate the bearings and chain and
interfere with the lubrication.

6.2 To lubricate the chain

The chain should be lubricated at regular intervals. If the
chain is dry, it can rust and get damaged.
1
Lubricate the chain with applicable chain oil.
2
Move the pedal a few turns, to let the oil go into the
link.
3
Wipe the chain with a cloth.

6.3 To adjust the brake handle

The brake should apply full power when the brake handle is
pushed halfway. The brake must not press against the rim
when the brake handle is not pressed. The handle must not
be pressed fully to the handlebar.
● Turn the adjusting sleeve in the brake handle to increase
or reduce the movement of the brake handle. (Figure 8)
● If larger adjustment is needed, release the wire lock on
the brake arm. Move the wire to required position and
fully tighten the wire lock. (Figure 9)
● To replace the brake wires, speak to an authorized
service center.

6.4 To adjust the spring tension

The spring tension prevents that the brake touches the rim
when the brake handle is released.
● Turn the adjusting screws on each side of the brake with
a suitable screwdriver until the arms move in parallel.

The brake pads should press against the middle of the rim.
