1.
Use a Philips Screwdriver to loosen
the brake housing anchor (do not
remove)
2.
Use a 12mm and a 17mm
wrench to loosen the rear
wheel axle on the left and right
sides at the same time, and
then slightly move the rear axle
back or forward along the slots
in the rear forks to get the right
chain tightness. Get the two 6
type washers to hold point A
(left and right) as shown. Then
re-tighten the rear wheel axle
with the cap nut.
Note:
Before re-tightening, the rear axle needs to be positioned evenly on each side
of the slots on the rear forks; try to align the rear chain sprocket and the front small
sprocket of the motor at same level.
WARNING
Failure to hold point A with 6 type washers could lead to the
rear wheel axle moving slightly, allowing the chaing to fall off.
3.
Re-tighten the cable housing
anchor, and adjust the rear brake if
needed.
