4.0 OPERATION OF THE BALANCER

WARNING: 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 balancing 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, inﬂ 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.

5. Be sure that the right size tire has been mounted

on the wheel.

Figure 11

4.2 WHEEL MOUNTING

The motorcycle 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

important 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 speciﬁ c adaptor, call your Snap-on distributor.

Motorcycle wheel adaptor shaft

The motorcycle wheel adaptor shaft has to be ﬁ tted by

the operator as speciﬁ ed below.

Checking and suppressing the residual unbal-

ance of the clamping means

In order to ensure good balance quality the residual

unbalance of the clamping means should not ex-

ceed 5 g if no wheel is clamped.

• Carry out a check run without wheel: Fully open out

the two driver segments (Fig. 12, Item 4) until the

pins engage; make sure they reach both the end

position!

Inputs to be entered for the check run:

– vehicle type: car

– distance: 200 mm

– diameter: 15”

– width: 3.5”

If the unbalance reading is 5 g or more, we recom-

mend that the adaptor unbalance be compensated

for in a compensation run.

Clamping motorcycle wheels

Refer to Figure 12.

• Open out the two driver segments (4) until they

engage. The wheel is driven by means of these

two segments.

• Push the wheel onto the centring cone of the

adaptor arbor, then push the counter cone (1) and

the distance sleeve (2) onto the arbor and tighten

with the clamping nut (3).

• Pull the locking bolt (5a) to disengage the driver

segment (4a), then move the segment slowly

inwards and ﬁ t it on the tyre.

• Repeat the same action for driver segment in

position (4b).

Motorcycles centring sleeves

Different centring sleeves (Fig 12a, Item 1) can

be supplied for motorcycle wheels on which the

bearings are shielded by gaskets so that centring of

the wheel is impossible by the cones of the adaptor.

Delivery of all motorcycle wheel adaptors comprises

two centring sleeves having an outside diameter

of 17mm, two centring sleeves of 20 mm outside

diameter and two centring sleeves of 25 mm outside

diameter (for BMW).

For further special clamping means (e.g. for mono-

lever wheels) see the Accessory Price List.

EEWB333B

4.3 MODE SELECTION

The majority of balancing takes place in the default

2-plane dynamic mode which is displayed as “2 PL”

(location 1). Hammer-on clip weights will be placed

on both inside and outside of the rim edge. If required,

select an optional weight placement mode by pressing

the Mode button until the appropriate placement mode

is displayed.

4.3.1 WEIGHT PLACEMENT MODES

Before Spinning the wheel (although it may be done

afterwards) choose the appropriate balancing mode

for the wheel. To select the various placement modes

press the (9) Weight Placement button (Figure 14)

until placement LEDs (Figure 14a) indicate desired

placement positions.

Due to the unbalanced mass the wheel has a heavy

and light side related to the axis of rotation.

Static imbalance is compensated far by ! tting counter-

balance weights to the light side of the wheel, either in

the center or on the sides of the rim.

To select the STATIC Mode:

1. Touch the SAPE arm to the rim " ange.

2. Enter the rim width dimension.

3. Press Alu button (9) four times.

WEIGHT COMBINATION MODES USING THE

WEIGHT SELECTION BUTTON

See (Figure 14). Pressing the weight selection button

(9) will toggle the LED’s to the weight default selections

as shown. Balancing using a combination of hammer-on

and adhesive weights as shown in Figure 17.

Figure 17

Figure 14a

Figure 14

A. DYNAMIC (two planes), suggested for all steel rims.

In this case the wheel weights must be clipped onto the

rim edges. This function is selected as a default and

the LEDs corresponding to the wheel weight location

are lit on Figure 15.

Figure 15

B. STATIC (single plane - Figure 16). Suggested for

narrow rims (3” or less). Use a single corrective weight

placed in the center of rim as illustrated in Figure 16.

Figure 16

With purely static imbalance the center of gravity and

thus the principal axis of inertia of the wheel is not on

the axis of rotation.
