4.0 OPERATION OF THE BALANCER

W

A

R

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.

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 Toggle” function.

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 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

ﬁ 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 ﬁ 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
