Re-checking the Balance
After installing the weights in the proper positions, lower the
hood or press
START to begin the spin mode. The weight
display windows should display
0 -- 0 to indicate a perfect
balance.
If the balancer indicates that an additional weight is
required in the same position as the first weight, then the
first weight installed was not heavy enough. Install a new
weight or add additional weight to the same area. Re-spin
the wheel and check again.
If the balancer indicates that an additional weight is
required opposite the position as the first weight, then the
first weight installed was too heavy. Correct the first weight
and re-spin the wheel.
If the balancer indicates that an additional weight is
required in a different position as the first weight, then the
first weight was installed in the wrong position. Correct the
first weight and re-spin the wheel and check again.
IDENTIFYING REMAINING WEIGHT
Your balancer is set to read
0 -- 0 if the wheel is
balanced within 5 grams on either side. If you wish to see
what remainder is left on each side ( less than 5 grams )
press the
FINE button.
After pressing the
FINE button, residual weight readings
will appear in the display windows.
STOP BUTTON
The
STOP button IS an emergency stop
button. It will immediately shut down the
wheel balancing operation. For emergency
situations that require immediate shutdown
of rotation, it is recommended that you
use the
STOP button and the TIRE STOP
PEDAL located on the right-front side of the unit.
After Balance Vibration Problems
If vibration is still present after balancing the wheels and
driving the vehicle on smooth pavement remove the
wheels and recheck the balance. If a wheel is out of
balance the cause may be:
1. A weight has come off the wheel. Remove the other
weights from the wheel and rebalance.
2. Tire slippage on the wheel. Remove and remount the
tire using proper tire lubricant and inflate to 40 PSI.
Do not over-inflate. Rebalance the wheel and reduce
air pressure to recommended PSI.
3. Stones or other foreign objects caught in the tire tread.
Remove the objects and repair tire as necessary. Check
and rebalance if needed. If the balancer still indicates the
wheels are balanced to within 5 grams on both inner and
outer displays, the problem is not in the balance of the
wheels. Check the following possible sources of vibration:
1. Tire pressure. Bring all tires up to the recommended
PSI.
2. Radial or lateral runout in the tire or wheel. Replace
the damaged part.
3. Foreign material inside the tire. Remove the tire from
the wheel, remove the material, and remount. Remove
wheel weights and rebalance the wheel.
4. Imbalanced wheel covers or trim rings. Remove the
wheel covers or trim rings and test drive, balance the
wheel with the wheel cover or trim ring attached to the
wheel.
5. Incorrectly mounted wheel. Remount correctly.
6. Damaged wheel bolt holes. Replace wheel.
7. Worn universal joints. Replace as required.
8. Drive shaft imbalanced or damaged. Balance, repair or
replace.
9. Imbalanced brake rotor(s) or drum(s).
10. Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.
