CHAPTER 1 – INTRODUCTION
1.1 INTRODUCTION
Th nk you for purch sing product from the line of wheel b l ncer. The m chine h s been
m nuf ctured in ccord nce with the very best qu lity principles. Follow the simple instructions
provided in this m nu l to ensure the correct oper tion nd long life of the m chine. Re d the entire
m nu l thoroughly nd m ke sure you underst nd it.
1.2 MACHINE IDENTIFICATION DATA
A complete description of the “Wheel b l ncer model” nd the “Seri l number” will m ke it e sier for
our technic l ssist nce to provide service nd will f cilit te delivery of ny required sp re p rts. For
cl rity nd convenience, we h ve inserted the d t of your m chine in the box below. If there is ny
discrep ncy between the d t provided in this m nu l nd th t shown on the n me pl te fixed to the
wheel b l ncer, the l tter should be t ken s correct.
1.3 MANUAL KEEPING
For proper use of this m nu l, the following is recommended:
• Keep the m nu l ne r the lift, in n e sily ccessible pl ce.
• Keep the m nu l in n re protected from the d mp.
• Use this m nu l properly without d m ging it.
• Any use of the m chine m de by oper tors who re not f mili r with the instructions nd
procedures cont ined herein sh ll be forbidden.
This m nu l is n integr l p rt of the m nu l: it sh ll be given to the new owner if nd when the
m chine is resold.
The illustrations have been made out of prototypes pictures. It is therefore
possible that some parts or components of standard production differ from those
represented in the pictures.

CHAPTER 2 – GENERAL INFORMATION
2.1 GENERAL SAFETY
• The wheel b l ncing m chine should only be used by duly uthorized nd tr ined personnel.
• The wheel b l ncing m chine should not be used for purposes other th n those described in the
instruction m nu l.
• Under no w y should the wheel b l ncing m chine be modified except for those modific tions
m de explicitly by THE MANUFACTURER.
• Never remove the s fety devices. Any work on the m chine should only be c rried out by
speci list personnel.
• Avoid using strong jets of compressed ir for cle ning.
• Use lcohol to cle n pl stic p nels or shelves (AVOID LIQUIDS CONTAINING SOLVENTS).
• Before st rting the wheel b l ncing cycle, m ke sure th t the wheel is securely locked on the
d pter.
• The m chine oper tor should void we ring clothes with fl pping edges. M ke sure th t
un uthorized personnel do not ppro ch the m chine during the work cycle.
• Avoid pl cing objects inside the b se s they could imp ir the correct oper tion of the m chine.
2.2 STANDARD SAFETY DVICES
• Stop key for stopping the wheel under emergency conditions.
• A wheel gu rd of high imp ct pl stic th t is designed to prevent the counterweights from flying
out in ny directing except tow rd the floor.
• A switch interlock system prevents the m chine from st rting if the gu rd is not lowered nd
stops the wheel whenever the gu rd is r ised.
2.3 INTENDED USE
• This wheel b l ncer h s been designed nd m nuf ctured exclusively for b l ncing wheel
with m ximum di meter of 1000mm nd m ximum weight of 75kg. The c libr tion system
is sufficient to cover different wheels from motorcycles to c rs.
• In p rticul r THE MANUFACTURER c nnot be held responsible for ny d m ge c used
through the use of wheel b l ncer for purposes other th n those specified in this m nu l, nd
therefore in ppropri te, incorrect nd unre son ble.
2.4 GENERAL CHARATERISTICS

4.3 WHEEL GUARD MOUNTING
• Mount the wheel gu rd onto the gu rd rm by the supplied screws ccording to Fig. 6.
• Check the micro switch is held down when the wheel gu rd is closed. Adjust it if necess ry.
Do not clean on the guard during the wheel balancing cycle.
4.4 ELECTRIC CONNECTION
Any electric connection job must be carried out by professionally qualified
personnel.
Make sure that the power supply is right.
Make sure the connection of the phases is right. Improper electrical hook-up can
damage motor and will not be covered under warranty.
• The m chine is supplied with single ph se m ins c ble plus e rth (ground)
• Check to m ke sure the ch r cteristics of your systems correspond to those required by the
m chine. The supply volt ge ( nd m ins frequency) is given on the m chine n mepl te. It
c nnot be ch nged.
• Connect the m chine to the m in electric power supply. If the m chine does not include the
electric plug, the user must set one, which must conforms to the volt ge of the m chine, in
compli nce with the regul tions in force.
• The m chine should not be st rted up without proper e rthing.

CHAPTER 6 – OPERATION OF THE WHEEL BALANCER
Do not use the machine until you have read and understood the entire manual
and the warning provided.
The wheel guard must not be opened before the wheel stops. The STOP button
serves to stop the machine immediately in emergencies.
Do not permit the control panel to get wet!
Chains, bracelets, loose clothing or foreign objects in the vicinity of the moving
parts can represent a danger for the operator.
6.1 BASIC OPERATION INFORMATION
The initial screen when switching on is in DYNAMIC mode.
• Mount the wheel on the sh ft of m chine. Use the most ppropri te mounting method. Alw ys
remove ny weight tt ched to the wheel.
• Switch on the m chine.
• Me sure nd entry the wheel d t .
• Select the most ppropri te b l ncing mode. The initi l screen when switching on is in
DYNAMIC mode.
• St rt the m chine. Performing spin c n be st rted by pressing START button or closing the
wheel gu rd if START FROM GUARD CLOSING is en bled.
• When the figures h ve been est blished, the spin is utom tic lly br ked to stop in the
correction zone. After the m chine stops, the unb l nced mounts re shown on the digit l
re douts.
• Rot te the wheel slowly by h nd until LED indic tors light up to indic te the correct ngul r
wheel position to pply the counterweights.
• Apply weights on the position for correction.
• With the counterweights correctly in position, rest rt the m chine to check the correct
b l ncing of the wheel.
• Reset the b l ncing mode referring to Fig. 8.
6.2 MOUNTING WHEEL ON SHAFT
A v oid bac k injury , seek assistance when lif t ing a hea vy wheel onto the bal ancer
shaf t.
Make sure to tighten the quick locking nut. Failure to do so may result in serious
personal injury.
• Select the most ppropri te mounting method for the wheel you re b l ncing. Using the
proper method ensures secure mounting nd s fe b l ncer oper tion, nd prevents d m ge to
the wheel.

REV. 01 2020 14 / 28
• On most wheels, the inner side of the wheel hub usu lly h s the most uniform surf ce for wheel
b l ncing. Alw ys center the wheel by the most uniform sh ped side of the hub to chieve the
most ccur te b l nce.
• Reg rdless of mounting type, lw ys m ke sure th t the wheel is forced firmly g inst the sh ft
f cepl te nd th t the quick locking nut is tightened. To ssist in centering the wheel properly,
rot te the wheel nd the sh ft while tightening the nut.
6.2.1 STANDARD BACK CONE MOUNTING (ref. Fig. 10)
Carefully clean the component surface before performing any operation.
Most steel wheels c n be mounted properly using this method. The wheel is centered on cone from
the inner side of the hub.
• Select the cone th t best fits the centre
hole in the wheels. Slide the cone onto
the sh ft with the l rge end tow rds the
f cepl te.
• Lift the wheel onto the sh ft nd centre it
on the cone.
• Att ch the pressure cup to the quick
locking nut nd inst ll the ssembly onto
the sh ft. Tighten securely.
6.2.2 STANDARD FRONT CONE MOUTING (ref. Fig. 11)
A wheel should be centered by the outer side of the hub only when the inner surf ce will not provide
n ccur te surf ce to center on.
• Select the cone th t best fits the center
hole in the wheel.
• Lift the wheel onto the sh ft nd slide it
b ck g inst the sh ft f cepl te.
• Slide the cone onto the sh ft nd into the
center of the wheel. You will need to lift
the wheel to se t the cone in the centre
hole.
• Inst ll the quick locking nut (without the
pressure cup) onto the sh ft. Tighten
securely g inst the cone
