Unpacking
Unpack the device using the correct tools. Pay particular attention to sensitive parts of
the machine, such as the keyboard, display, cover and clamping shaft.
Lifting the machine at the clamping shaft can cause damage to the sensors. The
supplier/manufacturer accepts no liability whatsoever for any resulting defects.
Setup
When setting up the machine, make sure that the applicable safety regulations are
observed.
A clearance of 50 cm must be maintained between the machine and the adjacent
walls/surfaces.
Usage & maintenance
- 7 -
The space required must be adapted to local conditions after fitting the wheel guard and
tightening the clamping shaft.
Avoid moving the machine by the wheel guard. This may result in damage to the guard’s
bearing or to the switch mechanism.
This machine must not be used in potentially explosive atmospheres.
Use anchoring bolts that fit into the machine's provided holes to ensure good anchoring
to the floor.
If the unevenness of the floor exceeds 0,25 %, sufficiently large shims may be used as
levelling material.
For a good operation it is absolutely necessary to anchor the wheel balancer to
the floor.
Electrical connection
The wheel balancer is designed to be connected to a standard 230 V/50 Hz socket.
The machine is equipped with a CE-approved plug as standard. The circuit for the
required socket must be separately fused.
Further electrical connection and reconnection work may only be carried out by a
qualified electrician in accordance with the regulations of VDE and/or the responsible
energy company. All applicable CE or DIN regulations must be observed.

Clamping a wheel
There are two different methods for wheel clamping.
Clamping method 1 - clamping cone on the rear of the rim
Most steel wheels can be mounted correctly using this method. The wheel is centered on a cone on the inside of
the hub.
•
Clean the surface of the rim before using this method.
•
Select the most suitable cone for the rim hub hole.
•
Slide the cone with the large ends in the direction of the flange on the shaft so that it rests against the flange.
•
Take a suitable plastic cap (optional) and place it on the quick-release nut.
•
Lift the wheel onto the axle and center the hub hole of the rim with the cone on top.
•
Attach the wheel to the axle using the quick-release nut. Make sure that it is correctly centered.
Clamping method 2 - clamping cone on the front of the rim
A wheel should only be centered like this when the inner surface of the cone does not allow the cone to be
correctly positioned. The wheel is centered on a cone from the outside of the hub.
•
Select the most suitable cone for the rim hub hole.
•
Lift the wheel in the direction of the flange so that it rests against the flange on the axle.
•
Slide the cone with the large ends outwards on the shaft.
•
Centre the hub hole of the rim by sliding on the cone.
•
Attach the wheel to the axle using the quick-release nut (without plastic cap).
-12 -
Correct handling of the quick-release nut and balance shaft
Note: Incorrect use of the quick-release nut or incorrect clamping and removal of
the wheel can damage the quick-release nut and the clamping shaft. The
manufacturer/importer/seller is not liable for damage caused by improper use.
This damage is not covered by the warranty.
Fastening and release of the wheel
•
When installing and removing the wheel, guide the rim evenly to the centering cone without touching the
clamping shaft as shown in Fig. 1.
•
Slide the quick-release nut by operating the mechanism to the edge of the rim. Do not use the mechanism for
tightening the quick-release nut but its handles.
Fig. 1 Fastening the wheel
•
Unscrew the quick-release nut until the rim is completely unscrewed, as shown in Fig. 2. Failure to do so may
result in damage to the quick-release nut and the clamping shaft.
•
When removing the wheel, take care not to damage the thread of the clamping shaft. Continue as shown in
Fig. 1.

Working with the wheel balancer
The main switch is located on the left side of
the machine chassis. A self-test is carried out
during operation. A sequence of numbers
appears on the display and after a few
seconds the display shows "a" and "8.0.
Clamp the clean wheel onto the clamping
shaft using the correct centering cone.
CAUTION: Even slight dirt on the contact
surfaces of the rim or on the flange of the
wheel balancer can lead to considerable
inaccuracies during the measuring
process.
The quick-release nut is used for even
clamping of the wheel.
The counterposition method is a commonly
used clamping method. Suitable for steel and
alloy rims.
-
Press the selected cone onto the balancing
flange.
-
Place the hub edge on the cone.
CAUTION: The clamping shaft must not
be damaged!
-
Tighten the wheel firmly with the plastic
pressure ring and quick-release nut.
Guide the tip of the distance meter to the rim
flange and read the value directly from the
ruler extension. Press the keys and enter the
read value using the distance key "a+" or "a-
". The left-hand display shows "a", the right-
hand display shows the value entered.
The rim width is determined with the rim width
gauge. Press the keys and enter the desired
value using the eel width keys.
Enter the value for "b+" or "b-". The left display
shows "b", the right display shows the value
entered.
-14 -
Press the diameter determination buttons
"d+" or "d-" to enter the diameter indicated on
the rim and tyre. The left-hand display shows
"d", the right-hand display shows the value
entered.
Close the wheel guard and balancing begins.
If button "1" is pressed while the wheel guard
is open, "ERR-5" appears immediately. On
low-turn (low-turn) wheel balancers, press
the START key to start.
The displays show the internal and external
imbalance value. Turn the wheel in the
desired direction until all LEDs on the left
side constantly light up the positioning
indicator. Attach the counterweight to the
inside of the rims in the 12 o'clock position.
Continue turning the wheel until all LEDs on
the right side of the positioning indicator light
up constantly and place the counterweight
on the outside of the rim in the 12 o'clock
position.
It may be necessary to repeat the procedures
described until the imbalance value "00" is
displayed.
After opening the wheel guard, the quick-
release nut can be released, and balancing is
complete.
When installing and removing the wheel,
the clamping shaft must not be damaged
by the edge of the hub hole.
This may result in measurement
inaccuracies and deformation of the
clamping shaft. Never load the clamping
shaft in any other way than intended!
-15 -
Self-calibration of the machine
Before commissioning and at regular intervals, depending on the frequency of use, a self-
calibration must be carried out. A monthly self-calibration cycle is recommended for normal
workshop use. This ensures that the measurement results are correct.
1.
To calibrate, use a 15-inch steel wheel (with rim + tyre, fully assembled) without
balancing weights and clamp it to the machine with the correct cone.
2.
Press the "F" and "C" keys simultaneously until the following screen appears.
3.
Close the wheel guard or press the green start button. The following figure appears after
the wheel has been braked.
4.
Turn the wheel until all indicators on the right light up and a beep sounds. Now clip on
the supplied 100g calibration weight at the 12 o'clock position on the outside of the rim.
Close the wheel guard or press the green starter button. The following figure appears
after the wheel has been braked.
5.
Turn the wheel until all indicators on the left side light up and a beep sounds. Now store
the supplied 100g calibration weight at the 12 o'clock position on the inside of the rim.
Close the wheel guard or press the green starter button. The following screen appears
after the wheel is braked and the calibration process is complete.

Balancing programs
The balancing programs must be selected by pressing the button next to the programs.
Standard program
Active without display in switch-on mode

The STATIC correction is used for motorcycle wheels and for wheels on
which a weight does not have to be applied on both sides of the rim.
ALU1
Balancing of alloy wheels with self-adhesive weights on the shoulder of
the rim.
ALU2
Balancing of alloy wheels with 2 adhesive weights on the inside.
ALU3
