PROCEDURE:
●
When the front fork is slightly swaying or when the direction handle is swung
Check if the pressure of the front tire is the recommended air pressure at room temperature: 280 kPa. If it is
lower than the recommended air pressure, the front tire pressure should be inflated to 350 kPa first, and then
deflated to 280kPa. If it is otherwise set the front wheel and turn to inspect the tire tread, if it is worn or
deformed, the front tire needs to be replaced. If no, continue to operate.
●
Check steering device
Set up the front wheel and shake the lower part of the fork by hand to check if the steering shaft is loose or if
the left and right rotations are not flexible.
Adjust the adjustment nut:
Remove the trim nut
⑴
with a 30# ring spanner, remove the gasket
⑵
, and remove the bolt
⑶
with 6# inner
hexagon socket. The direction of the upper board assembly wrapped with a clean cloth and then placed to
prevent scratches. Remove the lock washer
⑷
; remove the upper adjustment nut
⑸
with a hook wrench and
remove the pad
⑹
.
If the steering resistance is too large, turn the lower adjustment nut
⑸
counterclockwise. If the brake is
slightly swaying or swings, rotate clockwise. The torque is about 14N.m. It is appropriate.
When reassembling, the top adjusting nut only needs to be screwed to align with the bottom nut groove, so
as not to over-tighten to avoid excessive deformation of the pad
⑹
; the torque requirement of the decorative
nut
⑴
is 100 N·m.

Steering bearing
If the above operation still can not rule out excessive steering resistance or stuck as follows:
