9. Check wheel
9.1 Check tire
9.1.1 Tire status
The height of sliding block of
mud
tire must be checked regularly. The acceptable
minimum height is 2mm. If its height is lower than 2mm,
must
replace
new
tire.
9.1.2 Pressure
Tire pressure examination is aimed at cooled tires, so tires should not be used within a
few hours before examination. The recommended pressure for front and rear wheels is
225KPa.
Inappropriate pressure or tire may cause:
-
unexpected cracking
-
lose control of
bike
-
low
tire
pressure causes increased rolling resistance
-
reduce service time
-
clamping and piercing
9.2 Check wheel rim
Deformation examination for wheel rim should be conducted according to the following
steps:
• Put Light Bee
QL3000DY
on support at bracket area
• Confirm wheels rotate
properly
. Check whether wheels swing transversely (see Fig 22).
If swing transversely
occurred
, measure their transverse motion through indicator. If
transverse motion exceeds 1.5mm, check whether wheel rim is deformed or bearing is
damaged. If wheel rim is in a good condition, check whether tire is installed on wheel
rim correctly.

If wheel rim is
in
normal
condition
but the wheel rotate surface
is
not
vertical
to the
ground
(see Fig 23), bottom fork may be bended or
installed incorrectly
. Check bottom
fork.
