Press STOP key to unlock the wheel (user can also turn the wheel backward
ndt
o unlock the
wheel), search 2 weight position (i.e. OUTER (right) side) with the same way described on step
STEP 4
Apply a balancing weight with displayed amount to the OUTER (right) plane in the position on
the rim at top dead center 12 o'clock.
Automatic Position Search (
SPL
)
STEP 1:
Press the SPL key, the wheel rotates slowly, the INNER (left) weight
positioning bars are fully illuminated as the wheel stop at the s correction weight position I
NNER (left) (Top Dead Center of the rim).
STEP 2:
Apply a balancing weight with displayed amount to the INNER plane in the position
onto the rim at TDC (12 o'clock)
STEP 3
:
Press the
SPL
key, the wheel rotates slowly, the OUTER (right) weight positioning
bars are fully illuminated OUTER as the wheel stop at the (right) correction weight
position OUTER (TDC of the rim).
STEP 4:
Apply a balancing weight with displayed amount to the OUTER (right) plane in the
position onto the rim at TDC (12 o'clock).
（
SPL might locate at a position very close to TDC due to wheel weight deviation. Slightly rotate
the wheel forwards or rearwards until you get the buzzer sound.

windows if correct weights are applied to the correct positions.
Press
<T
Key to read the precise unbalance value.
**************************************************************************************
➢
During applying weights to verify the wheel balance, positioning error might happen, and
a few degrees error might cause a residual unbalance as large as 5-10 grams, especially in
case of large unbalance.
➢
In practical wheel balancing operations, available counter weights are 5 grams
increments, i.e. 5, 10, 15...60 grams etc. However, an actual unbalance results might be
any grams in between, for example, when there is a 23 grams unbalance in actual, and the
program will suggest 25 grams to balance it.
