IMPORTANT SAFETY INSTRUCTIONS

• Basic safety precau• ons should always be followed.

Wear safety goggles.

Read and follow all Instruc! ons and safety messages.

Wear appropriate clothing; keep hair and loose ﬁ # ng clothing, your hands

and all parts of your body away from moving parts.

Eye injury or other bodily injury can result from ﬂ ying par• cles or entanglement with

moving parts.

• Electric powered wheel balancer can cause shocks, ﬁ re or explosion.

Do not operate the wheel balancer with a damaged power cord or plug.

Do not use on wet surfaces, outdoors or expose the balancer to rain.

Unplug the power cord when the balancer is not in use.

If an extension cord is used, make sure that it is in good condi! on and that the cur-

rent ra! ng is 8 Amps or higher.

Use only in well ven! lated areas.

Do not operate the balancer in the vicinity of ﬂ ammable liquids (gasoline) or below

grade or in an explosive atmosphere.

Electric shock, ﬁ re or explosion can cause serious injury or death.

• Misuse of this wheel balancer can result in accidents.

Do not allow untrained or unauthorized personnel to operate the balancer.

Do not disable or bypass the hood safety interlock system.

Always securely ! ghten the quick nut that holds the wheel in place during the

moun! ng procedure.

Improperly balanced wheels can cause damage to the vehicle or automo• ve acci-

dents. Personal injury can result from altera• on to the balancer or improper use.

3.0 Introduction

Motorized wheel balancer that features extremely

fast

data entry, low cycle times with an improved user

interface making this a top choice for shops.

- Medium footprint motorized wheel balancer features

static and dynamic balancing modes.

- Features a touchscreen video monitor for easy to

read measurement results.

- Automatic mode selection by placing SAPE arm in

desired weight location.

- Laser guided weight placement for quick and accurate

tape weight placement.

- Sonar sensor measures rim width automatically.

- LED backlighting illuminates inside of wheel for

improved visibility.

- Split weight mode hides weight behind rim spokes

- Touchscreen facilitates faster navigation and

improved mode selection.

- Large stadium-style weight tray provides user with

easy access to storage pockets.

- Virtual Plane Imaging technology for unsurpassed

accuracy.

Always work in a clean area and with clean wheels.

First remove dirt and old weights from tires and rims.

That way proper mounting of the wheel and an optimal

balancing result can be achieved.

Application

The off-the-vehicle wheel balancer is designed for

dynamic and static balancing of passenger car and

light-truck wheels, that fall within the limits stated in

the technical speci! cations (F 1).

This is a high accuracy measuring device. Handle with care.

4.3 Main Shaft Lock

Fig. 4-17 Pedal of main shaft lock

The main shaft is locked when the pedal is depressed.

This facilitates tightening or loosening of the clamping

nut and retains the wheel in the correct position for

applying weights.

Note:

This lock is designed only to facilitate orientation

of the wheel and must not be used for braking the

main shaft.

4.5 Sonar Sensor

On the outer side of the rim the machine has a So-

nar sensor to measure wheel width (outside of rim)

(Fig. 4-19).

The sonar has a tolerance of +/- 0.5’’.

4.7 Help Information

Help information explains the current action and, in

the case of an error code, provides hints for remedy.

Display help information

— Press the HELP key (Fig. 4-10, Pos. 3).

The ! rst screen with help information appears, e. g. to

the screen RIM DATA INPUT (Fig. 4-20).

— Press the HELP key once more to display the next

screen with help information.

(if present)

The second screen with help information to the scree

n

RIM DATA INPUT (Fig. 4-21) appears.

Note:

On pressing the HELP key in the last screen with help

information the display jumps to the ! rst screen again.

Quit help information

— Press the ESC key (Fig. 4-10, Pos. 2).

4.8 Stop Button

Refer to Figure 4-22.

T

o perform an immediate stop:

• Press the Stop button:

The electric motor brake is activated to stop wheel

rotation.

In the event the balancer stops unexpectedly:

Check to be sure all inputs were completed prior

to the balancing spin.

If all parameters are inputted correctly:

• Restart the machine:

turn off the unit

turn on the unit again.

• Using the proper procedure input the parameters

and rebalance the tire.

• If the unit does not function correctly,

WARNING: PREVENT ANY FURTHER USE OF THE

UNIT.

• Call service 800-225-5786.

1 Cone for car wheels

2 Rim

3 Quick nut with pressure cup

DO NOT USE A HAMMER TO TIGHTEN THE

QUICK NUT.

Wheel mounting requiring special tooling

A clad wheel must be centered properly from the back

side of the wheel using precision collets 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

.

A centering cone can break off the tabs. See section

3.2 Optional Accessories (Pin Plate Set - Spacer).

5.1.1

Unclamping the Wheel

Note:

While the jaws unclamp, hold the wheel so that it

will not tilt when unclamped.

• Lower the brake pedal (Fig. 5-2).

• Remove the quick–clamping nut from the chuck (3,

Fig. 5-1).

• Remove the wheel.
