Spin Mode / Static - Ranger DST-2420 Installation And Operation Manual

Spin Mode / STATIC

This function is used if weights can only be mounted on
a single plane of the wheel.
1. Once the correct wheel data has been programmed,
lower the hood to begin the spin mode.
2. After the hood is lowered, or the START button is
depressed, the wheel will spin for approximately six
seconds then stop automatically.
3. After the wheel stops, a weight reading will appear in both
center display screens. The weight reading will appear
the same in both screens.
4. Turn the wheel by hand until the weight position indicator
lights on the side marked INNER are fully illuminated. The
OUTER indicator lights will not illuminate.
5. This indicates the position specified by the balancer for
the desired weight location on the chosen PLANE.
6. Attach the specified weight on the PLANE of the wheel
at top-dead-center.
Rechecking 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 CUT
button.
After pressing the CUT 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
shaft and wheel rotation. 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.
