To Determine The Proper Location For The Wheel Balancer:
WARNING: Make sure this machine is used on a dry, oil/grease free, flat, level CONCRETE
surface, capable of supporting the weight of the Wheel Balancer, the wheel being balanced, and
any additional tools and equipment.
2. The Wheel Balancer is designed for indoor use only. Do not install or use the Wheel
Balancer outdoors, or in damp or wet locations.
3. Make sure to check the desired location for possible obstructions such as a low ceiling,
adequate working area, access ways, and exits. The Wheel Balancer should be located in an area
free of flammable materials and liquids.

Mounting The Wheel Balancer to the Floor (if needed):

WHEEL BALANCERS DO NOT NEED TO BE MOUNTED TO THE FLOOR.
MOUNTING TO THE FLOOR IS RECOMMENDED IF THE BALANCER
“WALKS” DURING OPERATION; OR IF THE FLOOR IS NOT LEVEL.
IF THE FLOOR IS NOT LEVEL, THEN SHIMS MAY BE USED
UNDER THE ANCHOR POINTS TO “LEVEL” THE MACHINE.
STEP 1: With assistance, move the Wheel Balancer (in its upright position) to the desired work
location. Use the three, 1/2” machine mounting holes located at the base of the Body
as a template to mark the points where three floor anchor holes will be drilled in the
floor surface. Then remove the Wheel Balancer. (See Figure B)
STEP 2: 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.
Install the anchors, and bolt the balancer down.

Balancing Procedure for most passenger car and light truck
wheels:
STEP 1: Turn on the power switch and properly mount the wheel.
Enter the wheel data (“a”, “b”, and “c” dimensions).
STEP 2: Lower the protective cover, and press the “START” key. The wheel will spin.
After the spin has ended, the amount of weight needed on the wheel will be displayed
on the INNER and OUTER display windows.
(Select the weights to be used according to the values on the display.)
STEP 3: Slowly rotate the wheel counterclockwise, you will see the Weight Position LEDs for
the OUTER side change- All of the LEDs will light up when the position where the
weight will be added to is at top-dead-center (12 O’clock) (as shown in the following
figure). Attach the balance weight at the outside 12 O’ clock position of the rim.

STEP 4: Slowly rotate the wheel counterclockwise again, you will see the Weight Position
LEDs for the INNER side change- All of the LEDs will light up when the position
that the weight will be added to is at top-dead-center (12 O’clock) (as shown in the
following figure). Attach the balance weight at the inside 12 O’clock position of the
rim.

STEP 5: Put down the protective cover; press the “START” key. The wheel will spin again.
After the spin has ended, the display window should read: “00” “00”.If it does, the
wheel is completely balanced. If the display shows another value, add the weight
amount indicated according to the instructions above, and spin the wheel again. Most
wheels will require 3 or fewer cycles to successfully balance. Many will be balanced
on the first cycle. Practice makes perfect!

Weight Recalculation
This function can be used to correct a mistake made when entering the wheel data, after the
wheel has been spun. Re-enter the wheel data, without spinning the wheel again. Press the “C”
Key. The recalculated balancing weights are displayed on the windows.

To display imbalance weights less than 5 grams
For normal wheel balancing, the weight values are displayed in 5 gram increments (while in
grams mode). This accuracy level is sufficient to balance virtually all wheels correctly. If desired,
weight differences less than 5 grams can be displayed by pressing the “FINE” key.

Balancing modes
Press the “ALU” or “F” key to select the desired balance mode. The corresponding LED for the
selected mode will be lighted on the control panel. The following (cutaway) pictures explain the
weight locations (as placed on the wheel) for each mode:
Normal mode: the weights will be attached (clipped on) at
the edge of the wheel on both sides.
(shown in photo to right)

Refer to the above figure, take a measurement of each distance,
then enter the wheel data according to the following procedure:
Press the

keys to change the aI value.

Press the

keys to change the aE value.

Press the

keys to change the dI value.

Press and hold the

key, then press the

key to change the dE value.

Use the following instructions
to make the measurement more accurate:
STEP 1: Press the “START” key to begin the wheel spin, follow the procedure described in the
wheel balancing section to find out the weight’s radial position. Then, find out the
axial positions where the weight will be attached as follows:
STEP 2: Pull out the distance pointer to the distance of aI, hold the pointer position, and locate
the balance weight with the pointer. Then attach the weight at the position where the
Left LED fully flashes.
STEP 3: Pull out the distance pointer to the distance of aE, hold the pointer position, and
locate the balance weight with the pointer. Then attach the weight at the position
where the Right LED fully flashes.
STEP 4: Press [START] key, to spin the wheel again. When the remaining weight values are
less than 5 grams, the wheel is balanced.

OPTIMIZE BALANCING FUNCTION
This function is recommended only when the static balancing values are over 30 grams.
Use this function to optimize the balancing accuracy and reduce amount of weight to be added.
To get the best results, follow the following procedure carefully:
STEP 1: Press key [OPT], the display will read:[OPT] [
].
STEP 2: 2) Press [START] to activate a spin cycle. When the spin is finished, the will display
read: [ I ] [180 ]. The “180” displayed in the middle means the tire needs to be
remounted with the tire rotated 180 degrees from its current position on the wheel.
Mark the wheel and the balancer cone so that the same mounting position on the
balancer can be used in later steps.
STEP 3: Use a tire changer to re-mount the tire on the wheel, with the tire rotated 180 degrees
on the rim. Inflate the tire fully. Use the marks made earlier on the cone and wheel to
align the wheel and re-mount the wheel on the balancer.
STEP 4: Press [START]. After one spin cycle is completed, the display will read:[ #] [80┍┙].
The right window will indicate the static balance weight reduction rate after
re-mounting tire. This number is a percentage (“┍┙”= %).
The left window will indicate the weight to be added. See the example below:

In this example, 45 grams will be added. Add the weight indicated,
and perform a spin cycle to verify the wheel is balanced.
