N
IN
G: For operator safety please
read and follow the precautions outlined
on pages 1 and 2 of this manual.
NOTE: Read all instructions before pro-
ceeding with operation of the balancer.
All balancer functions are input into the main computer
through
the large easy to read
touch panel. Although
each wheel tire assembly differ in some ways all bal-
ancing jobs require basically the same procedure. The
order of events to take place are:
1. Inspection of the wheel/tire assembly
2. Mounting wheel onto shaft or adapter
3. Selection of Balancing Mode and Preferences
4. Entry of wheel parameters
Note: During an Alu P SAPE arm detection the Easy Alu
function automatically sets the desired weight location
by a suitable ALU mode selection.
5. Spinning the wheel
6. Applying the recommended weight
7. Check spin if desired
8. Dismounting the wheel
The following operation instructions will follow the basic
outline above.
4.1 CHECK LIST - INSPECTION
Observe Before Balancing Wheel
1. Check for proper air pressure.
If not correct, in! ate
to correct pressure.
2. Check for any foreign material inside tire. If present,
remove before balancing tire.
WATER IS FOREIGN MATERIAL!
3. Remove old weights old weights may be improper
value or in wrong location.
4. Be sure tire and wheel are free of excessive dirt,
rust and large stones. Use wire brush on back side of
wheel if necessary.
4.2 WHEEL MOUNTING
Nearly all standard wheels and many alloy wheels have
accurately machined center holes, and they should be
mounted with center cones. Accurate balancing depends
on accurate mounting of the wheel and correct seating of
the cone in the pilot hole. Insure that the wheel is centered
on the shaft exactly as it will be mounted to the vehicle.
Before starting any balancing procedure it is very im-
portant that the wheel is mounted on the machine with
the proper adap tors. An incorrect centering of the wheel
will result in considerable imbalance.
There are many types of wheels and Snap-on supplies
adaptors of good quality and durability for the large ma-
jority. However if you meet special wheels which may
require a speci" c adaptor, call your Snap-on distributor.
Rims may be divided into these major groups:
1. Car rims with a true center hole.
2. Car rims without a center hole.
3. Car rims with an untrue center hole.
4. Light truck rims.
5. Lug centric wheels
6. Clad wheels
4.2.1
STANDARD WHEELS (back cone mount)
Mount the wheel as detailed below in Figure 11
1. Mount proper cone against spring plate.
Figure 11
A
2. Mount wheel on shaft in the same manner as you
would on the car.
3. Mount pressure cup on shaft and place against
outside of wheel, follow with the Quick-nut.
4. Tighten Quick-nut securely with both hands. T
o
operate the Quick-nut pull the lock-unlock lever
(A, Figure 11). Slide the Quick-nut on the thread-
ed shaft. When in contact with the rim, release
the unlock lever and tighten " rmly. To assist in
centering the wheel properly, rotate the wheel on
the shaft while tightening the quick nut.
13
EEWB330B
FAILURE TO TIGHTEN
WING NUT SECURELY
MAY RESULT IN SERIOUS PERSONAL INJURY.
DO NOT USE A HAMMER TO TIGHTEN THE
QUICK NUT.
TO RELEASE THE QUICK NUT, UNSCREW A
FEW TURNS TO REDUCE THE AXIAL PRES-
SURE, THEN PRESS THE UNLOCK LEVER AND
SLIDE AWAY FROM THE SHAFT.
5. Check that the wheel rotates true by turning the wheel
several revolutions while noting any excessive runout.
4.2.2 CENTERING LIGHT-TRUCK
WHEELS
An optional offset spacer may be required for some
light truck wheels and reverse-offset
wheels that must
be moved away from the balancer mounting ! ange.
The extension adaptor is often used with the 5-1/4 inch
diameter light truck cone. (p/n EEWB-5)
Install the spacer on the mounting ! ange, then mount
the wheel, using the front cone method (Figure 12)
Figure 12
4.2.3 WHEEL MOUNTING REQUIRING
SPECIAL TOOLING
Cla
d wheels (Figure 13): A Clad Wheel is a wheel casting
that is
balanced but the wheel face is not " nished. To
" nish the wheel face a plastic chromed face is bonded
to the casting.
Figure 13
A clad wheel must be centered properly from the back
side of the wheel using a
precision collet instead of a
centering cone. A precision collet is normally a dual
sided centering device with low tapers on each side
and has a length of approximately 1.5 inches.
The bene" t of a precision collet is it " ts very precisely
into the tapered machining on the back side of a cast
wheel and the collet does not protrude into the wheel
center. A cone also offers precision centering, but a
cone can have a length from the long to short end of
the taper of two inches or more. A taper cone unlike a
precision collet, will intrude into the wheel center.
On many clad wheels there are plastic tabs to hold the
cosmetic cover in place. It is also necessary to use a
pin plate in the front of the wheel. The standard pres-
sure cup may crack the plastic cladding.
A centering cone can break off the tabs. See section
1.6 Optional Accessories for tooling recommendations.

marked on the sidewall of the tire (Figure 22 and 23).
Press the Diameter Button (D) and enter the measured
rim diameter by selecting the +/- keys until the desired
value appears in the display.
Select Enter to save selection.
4.5.3.1 Manual Distance Entry - Move the distance
gauge arm to touch the
inner edge of the wheel where
weights are to be placed and observe the reading on
the scale of the distance gauge. See Figure 24. Press
manual Wheel Offset button (O) followed by selecting
the +/- keys until value is displayed in the display window.
Select Enter to save selection.
NOTE: The parameter arm must be in the Home rest
position when the balancer is powered up.

4.6 Easy Alu FUNCTION
The E
asy Alu function automatically recognizes the
desired weight location by placing the SAPE arm in
the correct locations.
Note:
Alu 4 and Alu 5 are not included in the Easy Alu
function. They require manual setting by the operator.
4.6.1 Automatic rim dimension reading
and Alu P Mode selection
Preparations:
Compensation run carried out, if necessary.
Wheel correctly clamped.
Important: The OK indication and recommendation
for optimization, as well as the optimization procedure
itself, will only be accurate if the rim width is correctly
entered (Manual Input).
Automatic rim distance and diameter reading with
an internal gauge arm
Move the SAPE arm into position on the rim to select
the initial weight application position (internal rim
side). Keep it in this position until an audible signal
is heard.
Only for Alu2P and Alu3P (Fig. 25):
Position and hold the internal gauge in the
second position on the rim to select the
application position on the right side of the rim.
Shortly afterwards the machine emits an audible
signal to indicate that the machine automatically
saves the weight application coordinates.
Move the gauge arm to the idle position.
At this point you can change the Alu mode suggested
by the machine, using the Easy Alu Togglefunction.
Do this by pressing the button
once.
Spin the assembly.

4.7 SPINNING THE WHEEL
1) Manually activate the lever (1, Fig.26) to spin the
wheel. Wheels must turn clockwise.
2)
The operator must release the lever (1
) once the
rotation speed is reached.
The measurement is completed as soon as the direc-
tion indicators light up.
The unit beeps.
The brake will be applied automatically.

5.0 CORRECTION OF THE IMBALANCE
The fo
llowing weight types and application methods
are available:
Clip-on weights: Always apply by hand
Stick-on
weights: Can be applied by hand or us-
ing the gauge head for the Alu 2P, Alu 3P or easy
weight mode.
Hand applied weights MUST be applied exactly perpen-
dicular to the shaft (12 o’clock position). After Spinning
the wheel look at the rotation indicators for the left plane
of the wheel, Figure 27-A. As the correct Wheel Angle
Position (WAP) gets closer more indicators light up.
When all the indicators are ON, the WAP indicator will
also light up, Figure 27-B. Follow same procedure for
placing weight in the right plane.
Note: When the correct angle is reached, all the rota-
tion indicators should be ON. If the wheel has been
pushed too far, only the indicators of the other half will
come ON. If this happens, the wheel must be slowly
turned in the opposite direction until the WAP position
is reached. The weight amount to be applied in that
plane is shown on the display.
Attaching a clip-on weight.
Refer to Figure 28. Clip-on weights must always be
applied in the 12 o’clock position. The lip should rest
on the rim edge. Use the weight pliers to position it. In
STATIC mode only the left hand display is used.
Attaching a stick-on weight.
ALU or STATIC weight modes only: Refer to Figure 28a.
Apply the weight on the rim in the 12 o’clock position,
always by hand.
Note: With STATIC weight modes, always apply the
weight at the rim center line. If not possible, split the
weights evenly and apply on another surface of the rim
(symmetrical to the rim center line).

Alu P WEIGHTS APPLICATION WITH
THE SAPE
ARM
When
Alu
2P
or Alu 3P is selected (See Figure 27a-C),
The gauge arm is used to determine the desired weight
location, Extend the gauge to the inner position and wait
a few seconds for the placement to register, the place-
ment LED will ! ash during this time. See " gure 27a-D.
Figure 28b

Figure 27a
Extend the gauge arm to the outer position and wait for
the
signal to return the arm to home. Spin the assembly.
Use the gauge arm to position the corrective weights
as indicated by the display. Rotate the wheel until all
position LEDs are lit (A+B, Figure 27a). If correcting the
left plane, the right amount window will display a series
of dashes while searching for the placement location.
While moving the arm, a beep indicates when the cor-
rect application position has been reached. The weight
amount will then be displayed and ! ash and the WAP
indicator will lite up (Figure 27a-B). Press the foot pedal
to hold the wheel in this position. Apply the weight to
the correct point on the rim.
NOTE: Clean the area where the weight will be placed
before attaching the adhesive weights. In compliance
with the imbalance detected, approach at the gauge
head the suitable adhesive weight.(1, Figure 28b). Re-
move the protective tape (2, Figure 28b) from the stick-
on weight and apply it to the correct point on the rim.
Split Weight Mode or sometimes called Spoke Mode
can be invoked if desired. See chapter 6.0.
NOTE: Either left or right plane can be corrected " rst.
Rotate the wheel to the next position, put the stick-on
weight on the gauge arm and apply the weight for the
remaining position. After applying the balance weights
perform a Check Spin.
It is good practice to perform a check spin after applying
the weights. Spin the wheel. Having " nished the Run,
if the wheel is balanced correctly, both the numerical
indicators should indicate 000. To check how much
imbalance is left: Select the FINE key. The operator
should decide if applying additional weight is required.
Results recalculation. After Spinning a wheel it is possi-
ble to enter new rim data or select another weight mode.
The results are recalculated automatically. Selecting
another weight mode such as between NORMAL, ALU
and STATIC no additional steps required either.

6.0 SPOKE BALANCING MODE
When
spoke wheels are balanced, the behind–the–
s
p
o
k
e
s placement mode (also called split weight
mode) allows balance weights which would have to be
tted between two spokes according to the measured
unbalance (hence would be visible from outside) to
be placed in hidden position behind two spokes adja-
cent to the unbalance location. After a measuring run
the electronic unit calculates the behind–the–spokes
placement automatically and reads the relative balance
weight locations on the screen. The operating steps for
the behind–the–spokes placement mode are described
and illustrated below fi gure 29b
6.1 SPLIT WEIGHT MODE (SWM)
1. Select desired placement mode, ALU-2 or 3 will
both function with spoke mode.
Must be behind
the wheel weight position to select.
2. Measure position one and two with the gauge arm.
3. Perform a balance run.
4. Place inner corrective weights. Hold wheel as-
sembly secure with the foot brake when placing
weights.
HINT: Press the “Plus” key to quick spin the tire to the
next weight correction position.
5. Once you have a weight amount displayed. Ro-
tate the outer plane to the weight position indicat-
ed when all LEDs are illuminated.
6. Press the Mode key. Then press Enter.
7. The Spoke icon should illuminate as well as the
Mode LED.
8. Rotate the wheel to the rst spoke or closest spoke
position with P1 on the display. Press press the
enter key for position one. Figure 29c
9. Rotate the wheel to the second or next closest
spoke position with P2 on the display and press
enter. Figure 29d
10. The weight amount for correction is now divided
by two and displayed between the two spokes se-
lect.
11. Place the outer corrective weighs using the SAPE
arm
