wheel being balanced, and any additional tools and equipment.
The Wheel Balancer is designed for indoors use only. Do not install or use the
Wheel Balancer outdoors, or in damp or wet locations.
Make sure to check the desired location for possible obstructions such as a low ceil-
ing, overhead lines, adequate working area, access ways, exits, etcetera. The Wheel
Balancer should be located in an area free of flammable materials and liquids.
To Mount The Wheel Balancer On A Floor Surface:
With assistance, and with the use of a lifting device, stand the Wheel Balancer in its
upright position in the desired work location. Use the three, 1/2” machine mounting
holes located at the base of the Body (501) as a template to mark the points where
three floor anchor holes will be drilled in the floor surface. Then, temporarily remove
the Wheel Balancer. (See Figure B, next page, and Assy. Diagram D.)
Where previously marked on the concrete floor surface, drill three 1/2” diameter,
minimum 4” deep, anchor holes. NOTE: Be sure to blow out the cement dust from
the drilled holes.
Move the Wheel Balancer back to the desired location, and align the three machine
mounting holes at the base of the Body (501) with the three previously drilled floor
anchor holes. If necessary, level the Wheel Balancer by inserting steel shims be-
tween the base of the machine and the concrete floor surface. Do not exceed more
than 1/2” thickness of shims.

Wheel rim manufacturers usually indicate the wheel rim width (reading b) by
stamping the width numeric value into the top/outer edge of the wheel rim. Locate
the manufacturer’s stamped width numeric value on the wheel rim. NOTE: If the
manufacturer does not indicate the width, use the Rim Caliper that is provided
with the Wheel Balancer. To do so, position one tip of the Rim Caliper against the
top/inner edge of the wheel rim. Place the other tip of the Rim Caliper against the
top/outer edge of the wheel rim. The gauge on the Rim Caliper will indicate the
proper width. (See Figure F, and Figure G.)
Enter the width numeric value shown on the wheel rim (or Rim Caliper) by following
the instructions in Figure D.
Tire manufacturers usually indicate the tire diameter (reading d) by stamping the
diameter numeric value into the outer edge of the tire. Locate the manufacturer’s
stamped diameter numeric value on the tire. (See Figure F.)
Enter the diameter numeric value shown on the tire by following the instructions in
Figure D.

To Perform The Measuring Cycle:
Close the Safety Guard (504). (See Figure E, and Assy. Diagram D.)
Press the “START” key. (See Figures C, and D.)
The wheel will automatically accelerate to the balancing speed, and then automati-
cally brake (stop spinning).
Display A will indicate in numeric terms the inner side UNBALANCE VALUE, or
the amount of weight in ounces or grams that will be required to balance the inner
side of the wheel. (See Figure C.)
Display B will indicate in numeric terms the outer side UNBALANCE VALUE, or
the amount of weight in ounces or grams that will be required to balance the outer
side of the wheel. (See Figure C.)
NOTE: An UNBALANCE VALUE reading below 0.4 to 0.5 ounces (10-12 grams) is
normally sufficient for proper balancing. If a more precise reading is required (for
special wheels) the Threshold key may be used to reduce the reading below 0.2
ounces (5 grams) with the machine at a standstill.
To do so, refer to Figures C, and D.
Display P will indicate the correct location at which the weight should be attached
to the inner side of the wheel rim. If all the LED’s are illuminated in Display P, the
weight must be attached at the top of the vertical axis of the wheel rim. If not all
LED’s are illuminated, manually turn the wheel slightly to the right or left until all
the LED’s illuminate. Then, attach the weight at the top of the vertical axis of the
wheel rim. (See Figure C.)
Display O will indicate the correct location at which the weight should be attached
to the outer side of the wheel rim. If all the LED’s are illuminated in Display O, the
weight must be attached at the top of the vertical axis of the wheel rim. If not all
LED’s are illuminated, manually turn the wheel slightly to the right or left until all
the LED’s illuminate. Then, attach the weight at the top of the vertical axis of the
wheel rim. (See Figure C.)
Manufacturers of wheel rim weights typically stamp on the weight itself the amount
of weight in ounces and grams. Select the weight(s) (not provided) with the same
numeric values as are shown on Displays P and Display O. Then attach the corre-
sponding weight(s) respectively to the desired locations on the inner side and outer
side of the wheel rim, using the Weight Pliers provided with the Wheel Balancer.

To Perform The Self-Calibration Process:
Note: The 100 gram wheel weight (included) must be attached to the rim when doing
the self calibration.
Mount a balanced, or unbalanced, wheel with “normal” dimensions onto the Wheel
Balancer. (See Figure E.)
Make the wheel distance, width, and diameter measurements on the wheel, and
enter the numeric values. (See Figures D, and F.)
At the same time, press and hold down the keys “C” and “START.” Make sure not
to release pressure on either key. (See Figure D.)
On the inner side UNBALANCE VALUE digital display (A on the Control Board)
will appear the flashing letters “CAL” which indicates the machine is asking for
confirmation of the request for self-calibration. NOTE: If you wish to continue the
self-calibration process you must keep the two keys mentioned in Step #3 pressed
down until the letters “CAL” stop flashing. (See Figures C, and D.)
When the letters “CAL” stop flashing, release the keys “C” and “START.” Then, de-
press the “START” key only, and immediately release pressure on the “START” key,
to begin the first cycle of self-calibration. (See Figures C, and D.)
At the end of the first cycle of self-calibration, add a 100 gram weight. At the
same time, the outer side UNBALANCE VALUE digital display LED’s will flash (B
on the Control Board). At this time, use the correct keys to enter a weight of 3.5
ounces (or 100 grams) to the outer side UNBALANCE VALUE.
(See Figures C, and D.)
Depress the “START” key only, and immediately release pressure on the “START’
key. The machine will now be fully calibrated at the end of this cycle, and on the
inner side UNBALANCE VALUE digital display (A on the Control Board) will ap-
pear the flashing letters “END CAL” which indicates the self-calibration process is
completed. (See Figures C, and D.)
Note: The information that the Wheel Balancer records from the self-calibration process is
automatically stored and maintained in its memory bank. Even so, the self-calibration
process can be repeated as often as is desired or whenever the correct functioning
of the machine is in doubt.

The Optimizing Unbalance Process:
Note: The Optimizing Unbalance process allows you to reduce the amount of weight to
add to the wheel in order to balance it.
Mount the unbalanced wheel onto the Wheel Balancer. (See Figure E.)
Make the wheel distance, width, and diameter measurements on the wheel, and
enter the numeric values. (See Figures D, and F.)
Press the “OPT” key on the Control Board. The inner side UNBALANCE VALUE
digital display (A on the Control Board) will read, “r.S.” (See Figures C, and D.)
Press “START” so that the machine will begin a measuring cycle.
(See Figures C, and D.)
When the measuring cycle ends, the inner side UNBALANCE VALUE digital dis-
play (A on the Control Board) will give an instruction to turn the tire on the wheel
rim. Before doing so, make a reference mark with chalk on the Flange (23) of the
Wheel Balancer and the wheel rim in order to later match the exact points on the
wheel rim and tire bead when refitting. Then temporarily remove wheel from the
Wheel Balancer, deflate the tire, and use a tire remover (not provided) to rotate the
tire 180 degrees on the wheel rim. (See Assy Diagram A.)
Inflate the tire, and mount the wheel back onto the Wheel Balancer, using the chalk
mark in order to mount the wheel exactly as it was before. (See Figure E.)
Press “START” so that the machine will begin running a second measuring cycle.
(See Figures C, and D.)
When the measuring cycle ends, the outer side UNBALANCE VALUE digital display
(B on the Control Board) will read a numeric percent (%) which indicates a percent
of reduction in the UNBALANCE VALUE compared to the traditional method of ob-
taining the static UNBALANCE VALUE. At the same time, the inner side UNBAL-
ANCE VALUE digital display (A on the Control Board) will read the current static
UNBALANCE VALUE. This is the VALUE that can be reduced by the percentage
indicated on the outer side UNBALANCE VALUE digital display (B on the Control
Board). (See Figures C, and D.)
Press the “STOP” key to end the Optimizing Unbalance process. Repeat Step #3
above, and repeat the traditional measuring cycle process.

TO REPLACE THE FUSES: If it becomes necessary to replace the two electrical
circuit Fuses (415), remove the two Screws (505) on the front and two Screws (505)
on the back of the Tool Tray (506). Empty the Tool Tray of all weights, tools, etc.,
and remove the Tool Tray from the rest of the machine. Remove the two Fuses
from the Power Board (401), and replace them with two new Fuses. NOTE: Even if
only one Fuse is defective, it is recommended to always replace both Fuses at the
same time. (See Assy. Diagrams C, and D.)
