Selecting Balancing
Options
Round Off
The default weight measurement on the balancer is
0.25 ounces. The balancer can be set to a non-Round
Off mode that displays weights in 0.01 ounce incre-
ments. Press and hold the SHIFT key and press 6 to
toggle between the Round Off and non-Round Off
modes.
Ounce/Gram
In the default mode, the balancer will operate in
ounces. The balancer can be set to operate in grams by
pressing and holding the SHIFT key and pressing 9.
Toggle back to ounces by using the same key
sequence. LEDs on the control panel indicate which
weight measurement is currently selected.
Reading the Displays
Weight Displays
The 2 weight displays (one for the inner plane, and one
for the outer plane) are positioned with a wheel cross
section diagram. After spinning the wheel, the balancer
will calculate the weight needed and display it in these
displays. The display to the left of the diagram will show
the weight to be applied to the inner plane of the wheel
and the display to the right will show the weight for the
outer plane.
Error messages and system messages will also be
shown in these displays.
Weight Position LEDs
Each weight display includes weight position LEDs.
Located between the weight display and the diagram,
these LEDs indicate the proper location for weight
application. After a spin, rotate the wheel until the cen-
ter position indicator LEDs flash. This indicates that the
position specified by the balancer for weight application
is at top-dead-center.
Display Messages
Both inner and outer displays will show 0.00 when the
balancer is first turned on or after clearing the memory.
The balancer may also display the following messages:
Err - An error was detected after the start button was
pressed. The error is in one of the wheel measure-
ments entered into the balancer. Check your meas-
urements and re-enter as needed.
Err 3 - Circuit malfunction. Call the Hennessy Service
Department at (800) 688-6359.
Hub - The hub nut has come loose. The balancer will
automatically brake to a stop when the wheel is 13
inches or larger in diameter. Retighten the hub nut and
respin.
Balancing a Wheel
Procedure
The following steps walk through the balancing proce-
dure. Do not proceed with these instructions until you
have read and understand the previous sections of this
guide (mounting, balance modes, and reading the dis-
plays).
1. Turn the balancer on. The power switch is on the
rear of the unit, near the top and to the operator’s left.
NOTE: When turned on, the balancer will activate the
same options that were selected when it was last
turned off (hood start, ounce/gram, etc.).
2. Mount the wheel to be balanced. Use the proper
mounting method as described on pages 6 and 7.
Always remove any weights attached to the wheel.
3. Enter the wheel measurements and select balanc-
ing mode.
4. Set options (ounce/gram).
5. Press START. The wheel will spin and then brake to
a stop.
6. Rotate the wheel until the outer position LEDs
flash.
7. Attach the weight specified in the proper location
at top-dead-center. Refer to the diagrams on the control
panel for weight locations.
8. Rotate the wheel until the inner position LEDs
flash.
9. Attach the weight specified in the proper location
at top-dead-center. Refer to the diagrams on the control
panel for weight locations.
10. Press START to respin the wheel. The wheel will
brake to a stop. The weight displays should now read
0.00. If not, refer to page 11, Checking the Balance for
assistance.
REMEMBER: The more accurate you are in selecting
and positioning the weight, the more often you will bal-
ance wheels with a single spin.
