Tighten the screws for folding mechanism. The suggested torque is 15±1 N·m.If the stem
gets shaky when riding, tighen the screws on the folding mechanism when the scooter is
in folded state.
Tighten the screws on the brake disc assembly. The suggested torque is 8.5±0.5 N·m.
If the suspensions are not smooth or much harder when riding, add lubricant to
suspension internal structure parts.
1) Squeeze the brake levers, repeat 5 to 8 times, to enable the caliper fitted with the brake
pads grabs the rotor.
2) Tighten the bolts on the caliper. The suggested torque is 8.5±0.5 N·m.
3) Release the brake levers, spin the wheels. If the brake pads make contact with the rotor,
loosen the bolts on the caliper and repeat step 1.
4) The pushrod can be adjusted by a 2 mm wrench if necessary. Rotate the pushrod
clockwise to increase the length between the brake lever and the handlebar. Rotate the
pushrod counterclockwise to decrease the length.
The disc brake has the function of self-repairing. But when the brake pads are significantly
worn, they need to be replaced.
If the brake levers feel spongy when you squeeze them and the rotor makes abnormal
sounds, please stop riding immediately and replace them with the new brake pads.
