6.0 SPOKE BALANCING MODE
When spoke wheels are balanced, the behind–the–
spokes placement mode (also called split weight
mode) allows balance weights which would have to be
fi tted between two spokes according to the measured
unbalance (hence would be visible from outside) to be
placed in hidden position behind two spokes adjacent
to the unbalance location. After a measuring run the
electronic unit calculates the behind–the–spokes
placement automatically and reads the relative balance
weight locations on the screen. The operating steps for
the behind–the–spokes placement mode are described
and illustrated below fi gure 29b
6.1 SPLIT WEIGHT MODE (SWM)
1. Select desired placement mode, ALU-2 or 3 will
both function with spoke mode. Must be behind
the wheel weight position to select.
2. Measure position one and two with the gauge arm.
3. Lower the hood to perform a balance run.
4. Place inner corrective weights. Hold wheel assem-
bly secure with the foot brake when placing weights.
HINT: With the hood guard open press the “Plus”
key to quick spin the tire to the next weight correc-
tion position.
5. Once you have a weight amount displayed. Rota-
te the outer plane to the weight position indicated
when all LEDs are illuminated.
6. Press the Mode key. Then press Enter.
7. The Spoke icon should illuminate as well as the
Mode LED.
8. Rotate the wheel to the fi rst spoke or closest spo-
ke position with P1 on the display. Press press
the enter key for position one. Figure 29c
9. Rotate the wheel to the second or next closest
spoke position with P2 on the display and press
enter. Figure 29d
10. The weight amount for correction is now divided by
two and displayed between the two spokes select.
11. Place the outer corrective weighs using the SAPE
arm
