IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS
1. Eye and face protection recommendations:
“Protective eye and face equipment is required
to be used where there is a reasonable probability of injury that can be prevented by the use of
such equipment.” O.S.H.A. 1910.133(a) Protective
goggles, safety glasses, or a face shield must be
provided by the owner and worn by the operator
of the equipment. Care should be taken to see
that all eye and face safety precautions are followed by the operator. ALWAYS WEAR SAFETY
GLASSES. Everyday glasses only have impact
resistant lenses, they are not safety glasses.
2. Do not disable hood safety interlock system, or in
any way shortcut safety controls and operations.
3. Be sure that wheels are mounted properly, the
hub nut engages the arbor for not less than four
(4) turns, and the hub nut is firmly tightened
before spinning the wheel.
4. Read and understand this manual before operating. Abuse and misuse will shorten the functional
life.
5. Be sure the balancer is properly connected to the
power supply and electrically grounded.
6. Do not operate equipment with a damaged cord
or if the equipment has been dropped or damaged – until it has been examined and repaired by
a qualified serviceman.
7. Do not let cord hang over edge of table, bench, or
counter or come in contact with hot manifolds or
moving fan blades.
8. If an extension cord is necessary, a cord with a
current rating equal to or more than that of the
equipment should be used. Cords rated for less
current than the equipment may overheat. Care
should be taken to arrange the cord so that it will
not be tripped over or pulled.
10. Wear proper clothing. Safety toe, non-slip footwear and protective hair covering to contain hair
is recommended. Do not wear jewelry, loose
clothing, neckties, or gloves when operating the
balancer.
11. Keep work area clean and well lighted. Cluttered
and/or dark areas invite accidents.
12. Avoid dangerous environments. Do not use power
tools or electrical equipment in damp or wet locations, or expose them to rain.
13. Avoid unintentional starting. Be sure the balancer
is turned off and power disconnected before servicing.
14. Disconnect the balancer before servicing.
15. Use only manufacturer’s recommended accessories. Improper accessories may result in personal
injury or property damage.

perform all maintenance as required.
• Service and maintain the unit only with authorized
or approved replacement parts.
• Keep all instructions permanently with the unit and
all decals/labels/notices on the unit clean and visible.
• Do not override safety features.
Operator Protective Equipment
Personal protective equipment helps make tire servicing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting
clothing should be avoided. Tight fitting leather gloves
are recommended to protect operator’s hands when
handling worn tires and wheels. Sturdy leather work
shoes with steel toes and oil resistant soles should be
used by tire service personnel to help prevent injury in
typical shop activities. Eye protection is essential during
tire service activity. Safety glasses with side shields,
goggles, or face shields are acceptable. Back belts provide support during lifting activities and are also helpful
in providing operator protection. Consideration should
also be given to the use of hearing protection if tire
service activity is performed in an enclosed area, or if
noise levels are high.

Wheel Guard
CAUTION
Never raise up the wheel guard before the
wheel has come to a stop. Keep hair, loose
clothing, fingers and all parts of body away
from moving parts.
If, due to a fault in the machine, the wheel keeps spinning permanently, switch off the machine at the master
switch or by unplugging the plug from the power supply.
Wait until the wheel stops, or actuate the positioning
pedal before opening the wheel guard.
Positioning Pedal
CAUTION
Do not actuate the positioning pedal during
the measurement cycle. Do not use the positioning pedal as a brake.
After the machine has completed its spin cycle, use
the positioning pedal to hold the wheel position during
weight application. When you press the pedal with your
foot, the spindle shaft is locked.
If you have to brake the wheel in an emergency situation, while it is being spun by the motor, first disconnect
the power to disengage the motor and then use the
positioning pedal.
Auto Stop Feature
When the wheel is spun and out of balance measurements are displayed, the balancer’s auto stop feature
stops the wheel automatically at the corrective weight
location (12 o’clock).
Important: Always read and follow instructions. • 7
Mounting Wheel On Spindle Shaft
Select the most appropriate mounting method for
the wheel you are balancing. Using the proper method
ensures secure mounting and safe balancer operation,
and prevents damage to the wheel.
On most wheels, the inner side of the wheel hub usually has the most uniform surface for wheel balancing.
Always center the wheel by the most uniform shaped
side of the hub to achieve the most accurate balance.
Regardless of mounting type, always make sure that
the wheel is forced firmly against the shaft faceplate
and that the hub nut engages the threaded shaft for
at least four complete turns. To assist in centering the
wheel properly, rotate the wheel and the shaft while
tightening the hub nut.
CAUTION
Standard Back Cone Mounting
Most original equipment and steel wheels can be
mounted properly using this method. The wheel is centered on a cone from the inner side of the hub.
Failure to tighten the hub nut properly may
result in the wheel dismounting, causing
personal injury and property damage.
Figure 8 - Back Cone Mounting
1. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end
towards the faceplate.
2. Lift wheel onto the shaft and center it on the cone.
3. Attach the pressure cup to the hub nut and install
the assembly onto the shaft. Tighten securely.
Note: Use a nylon spacer (no mar ring) to protect custom wheel finishes.
4. Thread the hub nut onto the shaft, and tighten it
against the wheel. The wheel must be forced firmly
against the faceplate. The hub nut must engage the
threads for at least three full turns.
Note: If the hub nut will not tighten completely, use
the front cone mounting method.
8 • Important: Always read and follow instructions.
Standard Front Cone Mounting
A wheel should be centered by the outer side of the
hub only when the inner surface will not provide an
accurate surface to center on.
Figure 9 - Front Cone Mounting
1. Select the cone that best fits the center hole in
the wheel.
2. Lift the wheel onto the shaft and slide it back
against the shaft faceplate.
3. Slide the cone onto the shaft and into the center of
the wheel. You will need to lift the tire to seat the cone
in the center hole.
4. Install the hub nut (without pressure cup) onto the
shaft. Tighten it securely against the cone. The hub nut
must engage the threads for at least three full turns.
Note: If the hub nut will not tighten completely
because of a lack of threads, use an additional cone as
a spacer between the mounting cone and the hub nut.
The wheel must be forced firmly against the faceplate.
Important: Always read and follow instructions. • 9

Balancing Programs
A variety of wheel configurations can be balanced
using this wheel balancer. Read through this section, it
will help you determine which program and options are
best suited for certain wheel assemblies.
To perform a balancing cycle:
• Mount the wheel on the shaft using the most appropriate method. Refer to Mounting Wheel on Shaft,
pages 8 & 9.
• Remove any balancing weights, stones, dirt or other
foreign bodies from the wheel.
• If necessary, select a balancing program.
• Input wheel data correctly. Refer to Setting Wheel
Dimensions (DIM), pages 10 & 11.
Dynamic Balancing
Choose a dynamic balance to balance a wheel using
two planes for correction. Select the weight option that
best fits the available weight locations.
Clip-on Weights - The standard default; used for most

Note: When in static mode, you only need to input the
DIAMETER wheel measurement.
Important: If you decide to use the rim channel for
corrective weight placement, remember you may need
to adjust the DIAMETER measurement input. Typically
you would make it 2 or 3 inches less than the actual tire/
wheel diameter.
12 • Important: Always read and follow instructions.
Aluminium Wheel
Choose from 5 ALU programs that represent typical
corrective weight positions for aluminum wheels using
a dynamic balance. The balancer’s ALU programs calculate out of balance values based on the wheel dimension measurements (DIM) entered for the tire/wheel
assembly.

Important: Always read and follow instructions. • 13
Attaching Corrective Weights
• Rotate the wheel until the center indicator light
flashes and you hear a confirming beep.
• Attach the corrective clip-on weight amount at top-
dead-center (12 o’clock) on the tire/wheel assembly.
If the program ALU 1P is running, place the corrective Tape-A-Weight™ amount at the exact position
and plane chosen when entering the wheel measurement data.
• Lower hood and press to spin wheel and
check balance. Your weight readings should now be
0.00.
Match Balance (Optimization)
WARNING
The Match Balance involves the loosening of
tire beads and the inflation of a tire. Training
is necessary in tire changer operation and
understanding the dangers involved during bead seating and tire inflation before
attempting this stage of the Match Balance
procedure. Read the operators manual supplied with the tire changer and consult a
supervisor.
Use the Match Balance (Tire/Rim Weight Optimization) program to determine the best mating of tire and
rim that will result in the least amount of total out of
balance of the assembly. It requires two spins and two
rotations of the tire on the rim. Match Balance may be
needed when:
• The customer complains of ride problems.
• The balancer calculates a high out of balance.
Important: A high out of balance may indicate the
improper mounting of the assembly on the balancer, or
a rim that is out of round or misformed, or a tire with a
bubble or other problem. If the out of balance is excessive, it may be prudent to replace the rim, the tire, or
both. If either is replaced, do not continue with Match
Balance. Balance the new tire and rim and evaluate the
readings.
Match Balance Program
Choose the match balance program only after the
wheel has spun and the corrective weight amount is
displayed.
• Press or until the MATCH
balancing program LED lights up.
• Press to confirm your choice.
When you select this program, the balancer calculates
whether it is worthwhile. The balancer will flash the
message:
• Yes OPT if it is worth the effort.
• No OPT if it is not.
This calculation is made based on the out of balance
found with the last spin made (therefore, the last spin
must refer to the wheel on the machine).
You are now ready to move into the first stage of the
program as signaled on the display. If you do not want
to continue with this program, press

the end of the spin, the program goes into its second stage.
OPT 2
• Remove the rim from the balancer.
• Put the tire on the rim. Put the tire on the balancer.
• Turn it until the valve is at 12 o’clock.
• Press .
• Make the second spin. At the end of the spin, the
program goes into the third stage of the OPT program.
OPT 3
• Turn the wheel until the segment in the middle of the
screen lights up to indicate the position.
• Make a chalk mark on the outside wall of the tire at
12 o’clock.
.
• Press
• Make the forth spin. At the end of the spin, the OPT
program is complete, and the machine displays the
corrective weight amounts to balance the wheel.
If you make an error, which will negatively affect the
end result, the machine will tell you this by, displaying a
message: OPT Err. This means you need to repeat the
entire procedure from the beginning.
Note: If you do not want to make the first spin with
just the empty rim, you can skip the first phase by
pressing
for the OPT program. This will mean that you start by
mounting the rim plus tire on the balancer and carrying
out phases 2, 3, 4 as previously described.
Note: At the end of the second and third spin you may
get the message OUT 1 or OUT 2 on the screen. This
means that you are better off abandoning the program
by pressing the . The display will then give the
weights needed to balance the wheel. This allows you
to short cut (exit) the program by accepting the current
status. If you want to carry on to the end, press the

immediately after pressing the
• Remove the wheel from the balancer.
• Turn the tire on the rim until the chalk mark is opposite the valve (i.e. 180°).
• Remount the wheel on the balancer until the valve
is at 12 o’clock.
• Press .
• Make the third spin. At the end of the spin, the pro-
gram goes into its fourth and last stage.
OPT 4
• Turn the wheel until the segment in the centre lights
to indicate the correct position.
• Make two chalk marks on the outside wall of the tire
at 12 o’clock. If the screen gave you the message to
switch around the tire as it is mounted on the rim,
make these two chalk marks on the inside wall of
the tire.
• Turn the tire on the rim (and switch it around if this is
called for) so that the two chalk marks are opposite
to the valve.
and you will continue in the OPT program.
Note: At the end of the third spin the screen may sug-
gest that you switch the tire around on the rim. If you do
not want to or cannot do this, press . The screen
will display instructions on how to complete the OPT
program without making this switch.
Quick OPT Program
In the vast majority of cases this program gives results
almost as good as the full OPT program described
above, although it requires fewer spins.
Proceed as outlined above in the previous heading
with the difference that the first stage of the quick optimization program corresponds to the second stage of
the standard program.
You therefore start work with the tire already on the
rim and then proceed with the successive stages.
• Mount the wheel on the balancer.
• Turn the wheel until the valve is at 12 o’clock.

Calibration Program
First Sensitivity Calibration
This program needs to be run whenever the settings
appear to be out of tolerance or when the machine
requests self-calibration spontaneously by displaying
the message “Er1 CAL”.

can be pressed at any given moment
Second Sensitivity Calibration
This program is used to self-calibrate the machine to
make it extremely accurate even with very high out of
balance values (over 200 g of static unbalance with average size wheels). It should be done when the machine
itself calls for it by displaying the message “Er2 CAL”.
• Press to confirm your choice.
• The machine is now ready to carry out first sensitivity
calibration and displays the message “CA.1”.
• Rotate the wheel until the center indicator light
flashes and when the value ”100” (or 3.5 if ounce
mode is selected) is on the display.
• Attach a 100 g (or 3.5 oz) sample weight to the OUT-
SIDE of the wheel rim. Position it at top-dead-center
(12 o’clock) exactly.
• Lower hood and press to spin wheel.
• With the wheel stopped, remove the sample weight
from the outside plane and rotate the wheel until
the center indicator light flashes and when the value
“100”(or 3.5) is on the display.
• Attach the 100 g (or 3.5 oz) sample weight once
again to the OUTSIDE of the wheel rim. Position it at
top-dead-center at 12 o’clock exactly.
• Select a wheel of average size and weight, preferably
with a limited unbalance, and mount it on the shaft.
• Enter the correct wheel dimensions for the wheel.
• Press or until the CAL pro-
gram LED lights up.
• Press twice to confirm your choice. The
machine is now ready to carry out second sensitivity calibration and will signal this with the message
“CA.2”.
• Follow all the steps outlined above for first sensitivity
calibration.
• Lower hood and press
When the calibration program is completed successfully, it is confirmed by a beep following the spin. If not,
the message “Er3 CAL” is displayed.
The self-calibration program ends with the display

Diagnostic Procedures
After Balance Vibration Problems
If vibration is still present after balancing the wheels
and driving the vehicle on smooth pavement, remove
the wheels and recheck the balance. If a wheel is out
of balance the cause may be:
• Wheel was not mounted/centered correctly on the
balancer.
• A weight has come off the wheel (possibly the
wrong clip style). Remove the other weights from
the wheel and rebalance.
• Foreign material inside the tire. Remove the tire
from the wheel, remove the foreign material, and
remount. Remove wheel weights and rebalance the
wheel.
• Stones or other foreign objects caught in the tire
tread or rim. Remove the objects. Check and rebalance if needed.
If the balancer still indicates the wheels are balanced
to within 0.10 ounces on both inner and outer displays,
the problem is not in the balance of the wheels. Check
the following possible sources of vibration:
Balancing Accessory Availability Status
This check permits you to make sure that wear has not
altered the mechanical specifications of flanges, cones
and so on beyond the specified limits.
The test is carried out with a perfectly balanced wheel
(to zero without the threshold and showing the first
gram). When this wheel is mounted on the balancer,
removed and remounted in a different position the
unbalance weight shown should not be more than 10
grams.
If the unbalance is higher, check all the accessories
with care and replace any that show dents, abnormal
wear, bent flanges and so on.
Always remember that if you are using a cone to
center the wheel on the shaft, you will never get good
results if the centre hole in the rim is not perfect, i.e. off
center or out-of-round. Results are always better when
the wheel is centered with the rim holes.
A last important point: any difference between the
way the wheel is mounted on the car and on the balancing machine will generate some unbalance.
• Tire pressure. Bring all tires up to the recommended
PSI.
• Radial or lateral runout in the tire or wheel. Replace
the damaged part.
• Unbalance in wheel covers or trim rings. Remove
the wheel covers or trim rings and test drive. If
the vibration is gone, remove the shaft and use
an appropriate adapter to mount the wheel to the
balancer. Balance the wheel with the wheel cover
or trim ring attached to the wheel.
• Incorrectly mounted tire and wheel. Remount correctly.
• Damaged wheel bolt holes. Replace wheel.
• Worn universal joints. Replace as required.
• Drive shaft unbalance or damaged. Balance, repair,
or replace.
• Unbalance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.
Important: Always read and follow instructions. • 17

Maintenance Instructions
The balancer requires only minor maintenance to keep
the unit operating properly.
1. Keep the display clean and clear. Use a damp cloth.
Do not use cleaners or solvents which leave oily or filmy
residues behind.
2. Keep the adapters, cones, faceplate, threaded
shaft, pressure cup, and hub nut clean. Grease and dirt
buildup will cause inaccurate balancing and premature
wear. Clean these items at least once a day with a
vaporizing solvent.
3. Clean weight tray and any accessory posts, pegs,
or storage shelves with a vaporizing solvent. Weights
stored in a dirty tray may pick up grease and dirt which
may keep them from securely attaching to the wheel.
WARNING
Use common sense, this is an electrical
device. Exposing the balancer to water,
either by hose or bucket, or by exposure
to rain or snow, may cause risk of shock
or electrocution to operator or bystanders.
Place, store, and operate the balancer only
in a dry, sheltered location.
CAUTION
Do not hose down with water or bucket
wash the balancer. Extensive damage to
the balancer will result. Sensitive electronic
components, wiring harnesses, and other
devices housed in the balancer are not
intended to be exposed to water.
4. Keep the area around and under the balancer
clear. Remove any tools or other items that are leaning
against the balancer. Remove any items that may cause
the balancer to not sit level. Be particularly cautious of
new or used wheel weights on the floor, as they may
cause personal injury due to falls.
5. Use only BaseLine™ accessories. Accessories
from other manufacturers may not fit or function properly, and may damage the balancer.

Glossary Of Terms
Balancer Flange – Disk that mates with the disk of
the wheel mounted to the balancer. The flange also
serves to keep the wheel perfectly perpendicular to its
axis of rotation.
Balancing Cycle – Sequence of operations performed
by the user and the machine, beginning from the start
of the wheel spin to the time that the wheel is stopped;
at a standstill, after the out of balance signals are
acquired and the relative values calculated.
Centering – Procedure for positioning the wheel on
the spindle shaft with the aim of ensuring that the
rotational axis of the wheel is aligned with the center
of the shaft.
Centering Flange (accessory) – Device serving to
support and center the wheel. Also keeps the wheel
perfectly perpendicular to its axis of rotation. The centering flange is mounted to the balancer shaft by means
of its center hole.
Cone – Conical components with center hole. When
inserted on the spin shaft, serves to center wheels with
centre holes whose diameter is between maximum and
minimum values.
Dynamic Balancing – Operation in which out of bal-
ance is corrected by the application of two weights, one
on each side of the wheel.
Self-calibration – A procedure whereby suitable cor-
rection coefficients are calculated by starting from
known operating conditions. Self-calibration improves
the measurement precision of the machine by correcting, within limits, calculation errors that may arise due
to alteration of the machine’s characteristic over the
course of time.
Spin – Procedure starting from the action that causes
the wheel to rotate and the successive free rotation of
the wheel.
Hubnut – Device for clamping the wheel to the bal-
ancer. The hubnut features elements for engaging to the
threaded hub and lateral pins that are used to tighten it.
Static Balancing – In static balancing only the static
component of unbalance is corrected. This is achieved
by fitting a single weight, usually at the center of the rim
channel. The accuracy of this system increases as the
width of the wheel decreases.
Threaded Hub – Threaded part of the shaft that is
engaged with the hubnut to clamp the wheel. This
component is supplied disassembled from the machine.
Unbalance – Non-uniform distribution of the wheel
mass that results in the generation of centrifugal force
during rotation.
