Enter the wheel parameter data using the auto-

matic A/D arm.

Note: If you do not get proper wheel param-
eters from the A/D Arm, check the A&D
potentiometers found in the CALIBRATION
MENU, follow the procedures for Arm cali-
bration. If the A/D arm has failed, you may
manually enter the data. If the Keypad does
not work, see TOUCH PANEL PROBLEMS.

4.

If the balancer is in round off mode, go to the SET

UP menu, select NON-ROUND OFF and press enter.

Go to the SET UP menu, select the desired weight

mode (this procedure may be performed in either

Install a 4 oz./100 gram weight on the outer rim of

the test wheel.

8.

Lower the guard hood. (if HOOD START is on, the

balancer will automatically cycle at this time, if not see
step 9).

9.

Push the START button. The machine should now

cycle. If the machine does not cycle, see BALANCER
DOES NOT SPIN.

10.

The balancer should come up to speed, coast for

several revolutions, and then brake to a stop. If the
machine fails to brake and continues to coast, see BAL-
ANCER DOES NOT STOP.

11.

The balancer should now have weight values and

position lights displayed.

12.

Rotate the wheel so the top and bottom position

LED's for the outside (right) plane are flashing.

13.

Note the position of the 4 oz. weight and the

weight readings for both planes.

14.

Now rotate the wheel so the center LED for the

outer (right) plane is flashing. The 4 oz. weight should
now be at (or near) the 6:00 position.

15.

Perform five (5) cycles and note the positions and

weight readings after each spin. The weight readings
should repeat within .2 oz. and the position 1/2
inch. If they do not, see ACCURACY PROBLEMS.

Note: If the customer has problems with a
specific wheel assembly only, make sure there
is no water or debris inside the assembly.
