How To Fix Side Shaking - MINOURA WORKMAN PRO Manual

If the rim shakes to downward, tighten both side
nipples.
And if the rim shakes upward, tighten both far side
nipples. Do not loosen the nipples.
Because the nipples are made by soft material, brass
or light alloy, so its thread can be broken easily by
loosening.
Tighten Group-A nipples about 1/8 turns, Group-B
about 1/4 turns, and Group-C about 1/2 turns. And
then check the vertical shaking with rotating the wheel
slowly again.
If the wheel shakes yet, continue the process again.
When you hear strange sound from the nipples or see
some kind of strings while you tighten the nipples,
the thread of the nipples will be broken soon. But do
not apply any oils to the nipples to remove the sound,
and try to exchange the nipple to the new one as soon
as possible.
The side shaking within 2mm may not cause any
troubles. But if you want to be it zero, you can try
again and again with the following process.
You can see two knob bolts on both side of the U-
shaped gauge frame. Put the tips of them close to the
surface of the rim. Do not touch the rim.
Rotate the wheel slowly, and check the side shaking.
And stick vinyl tapes to two spokes; one is the begin-
ning amd one is in the ending of the side shaking.
Make three groups of these spokes between the vinyl
tales as below;
: Three or less spokes in the beginning
and in the ending of side shaking.
: Three or less spokes between Group-
A except for the center one.
: The center one between the vinyl tapes.
If the rim shakes to the right, tighten the left side
spokes. Do not loosen the right side spokes. Because
the nipples are made by soft material, brass or light
alloy, so its thread can be broken easily by loosening.
Tighten Group-A nipples about 1/8 turns, Group-B
about 1/4 turns, and Group-C about 1/2 turns.
And then check the side shaking with rotating the
wheel slowly again.
If the wheel shakes yet, continue the process again.
