SENSITIVITY:
1.6 ounce inches, equal to 1/5 OZ. weight at 8 inch radius.
Sensitivity is defined as the smallest amount of weight which will cause visible
movement of the balance indicator.
ACCURACY:
2.0 ounce inches, equal to 1/4 OZ. weight at 8 inch radius.
Accuracy is defined as the maximum average weight variation from perfect
balance.
The wheel balancer and ABC wheel weights make up the wheel balancing system.
b.
"ON-OFF" POSITIONS: The balancer head pivots on a hardened ball point
resting on a flat ground seat.
In the "OFF" position the balancer head rests on
the outer rim of the oil basin, not on the pivot point. This permits wheels to
be put on or taken off the balancer and weights to be pounded onto the wheel
while it is still on the balancer without damaging the super-sensitive and
accurate pivot point and seat.
In the "ON" position the head has been raised and is supported on the pivot
point.
With a wheel in position on the head, the balancer now becomes a very
sensitive and accurate weighing device.
To turn the balancer "ON" gently depress the pedal all tile way down with your
foot.
The head and wheel are raised and the balancer is active.
The pedal
stays down and is held in the "ON" position by the weight of the wheel.
c. AUTOMATIC "OFF": When the weight of the wheel is removed from the
balancer, the head and pedal automatically return to "OFF". This protects the
pivot point from damage should anyone drop a wheel onto the balancer.
d. MANUAL "OFF": While the wheel is on the balancer the machine may be
turned "OFF" by raising the pedal to the "OFF" position with your toe. `To
protect the accuracy of your balancer, the machine should be turned "OFF" when
attaching weights to the outside rim of the wheel while the wheel is still on
the balancer.
NOTE
ABC Wheel Weights are required for successful use of the wheel
balancer.
Thinline ABC weights fit all vehicles with 13-, 14- 15-, or 16-inch
rims , except for those vehicles that have a straight-lipped rim on the
outside.
Special ABC weights are designed with a long clip that fits only the
outside straight lip of the rim.
Corresponding thinline and special ABC weights have the same weight
and must be used together on wheels that require special weights: two
special weights on the outside rim and two corresponding thinline
weights on the standard inside rim.
