Arrow showing where to look
1.2 Scope of application
The off-the-vehicle wheel balancer is designed for static and/
or dynamic balancing of car and light-truck wheels weighing
up to 150 lbs and having an overall diameter of 44”.
In addition to conventional balancing operations, irregular run-
ning conditions of the wheel caused by geometric deforma-
tions of the rims and/or tires, hence unsmooth ride, can be
identied, improved or, if possible, even eliminated. By exact
adjustment of the two wheel components relative to each
other optimum wheel running conditions or at least balance
weight minimisation can be achieved.

1.3 General safety rules
Only properly trained and authorised personnel shall be al-
lowed to operate the wheel balancer.
The machine must not be used except for the scope of ap-
plication and in the way specied in this manual.
Unauthorized changes and modications to the machine
relieve the manufacturer from any liability for damages and
injuries that might result therefrom.
On no account should safety features be removed or made
inoperative.
In general any work on the electrical system such as tting of
a plug or changing of connections, if necessary, must be car-
ried out by a qualied electrician in line with relevant national
standards and the regulations of the local power station.
It should be noted that working with technical equipment may
involve an unforeseeable acceptable risk.
Therefore the operator should eliminate such dangers in
advance by proper and wise behavior.
The following special points should be observed:
Use technical equipment for its specied scope of application
only.
Always use suitable and proper equipment and tools.
Follow the instructions, notes and technical data of the
machine manufacturer or manufacturer of the wheels to be
balanced.
Wear suitable protective clothing and accessories (e. g.
goggles, safety shoes, helmet).
For further safety rules to be observed, please refer to the
individual chapters.

1.4 Description of function
Display and key pad
The display and key pad are arranged on the ergonomic front
panel.
Gauge arm for distance and rim diameter
Entry of rim diameter and distance between left correction
plane and machine is by means of an integrated gauge arm
or also via the key pad. In the latter case the relative function
key is held pressed while the wheel is rotated to choose the
desired inputs and enter them by releasing the function key.
When tting adhesive weights with the weight holder, the
machine will support the operator in relocating the correction
position.
Rim width is entered via the menu keys and rotation of the
wheel.
Balancing mode
Readings in different balancing modes (weight position on
the rim) can be given on the display, depending on the type of
wheel to be balanced (car, light-truck, motorcycle, PAX, steel
or alloy rim).
Measuring run and measured values
All measurements are taken and stored in one run during
the automatic program. On completion of measurement the
machine stops automatically and the wheel is slowed down
to standstill. Amounts and locations of unbalance are read out
separately for each correction plane. Main shaft lock
The machines have a pedal-operated main shaft lock which
is used to retain the wheel in the correction position so that
the balance weights can be tted. This lock is designed only
to facilitate orientation of the wheel and must not be used for
braking the main shaft. Store wheel proles
Wheel proles permit the storage of values for wheels that
are balanced frequently in order to save having to enter the
wheel data etc. each time. It is possible to store up to 4 wheel
proles.
Error codes
Errors in operation or failures in the electronic or mechanical
system are signalled via respective error codes (see § 11.
Error codes).
User calibration
If several measuring runs are necessary to balance a wheel
because balance weight size and position have to be adjusted
repeatedly, this is often due to insufcient measurement ac-
curacy.
In such case the operator has the possibility of readjusting the
machine (see § 13. User calibration). Wheel guard
A wheel guard with electric interlocking is mandatory for the
European Union and is part of the standard equipment. The
measuring run may only be started with closed guard. The
electronic unit can be programmed via code C13 so that mea-
surement is started by closing of the guard.

Installation of the machine
2. Installation of the machine
When choosing the site, Health and Safety at Work regula-
tions and the regulations on working environment should be
taken into account.
The wheel balancer can be installed on any rm and level
ground. For the weight and space requirement of the machines
refer to § 15., Technical data. For installation on an upper oor,
observe permissible load capacity of the oor.
It is recommended, though not absolutely necessary, that the
machine be secured to the oor. For this purpose three holes
(Fig. 2) are provided in the base of the machine by which the
latter is xed on the oor with 3/8 ” anchor bolts. Fig. 2 shows
the center-to-center distance of the holes. Make sure that the
machine has a stable position, i.e. that it is supported on three
seatings. If not, ensure three-point contact on ground by
inserting appropriate spacers between the oor and machine
base.
For ease of transport the wheel balancer is disassembled
into the following units and provided with special packing (on
pallets):
- Machine
- Wheel guard
2.1 Unpacking the machine
The machine should be unpacked by two persons.
Note
When unpacking the machine make sure that the pedal tted
on the machine base and the whole pedal assembly is not
damaged.
•Cut the strips of the packing (Fig. 3, item 1), lift off the
packing, and set aside the wheel guard and the small
parts packed in the separate small box (Fig. 3, item 2).
• Unscrew the three hexagon screws (use a 1/2 ” wrench
to) which hold the machine on the pallet (Fig. 4, ar-
row).
•Lift the machine by tube of the vibratory system and
wheel guard arbor and turn around by 180 degrees on
the pallet (Fig. 4).
•Then lower one side of the machine laterally on the
oor (Fig. 5).
•Remove the pallet from underneath the machine and
gently lower the entire machine onto the oor (Fig. 6).
2.2 Resiting the machine
If the machine is transported on site, gently tilt it, taking it by
weight box and wheel guard arbor, and push it gently on suit-
able lifting or mobile industrial handling equipment (e. g. forklift
truck, platform truck).
Note
When lifting the machine bear in mind the centre of gravity of
the machine and avoid oscillating movements.

In general any work on the electrical system such as tting of
a plug or changing of connections, if necessary, must be
carried out by a qualied electrician in line with relevant
national standards and the regulations of the local power
station.
Installation of the machine
2.2 Mounting the wheel guard (Fig. 7)
•
Slide the wheel guard (Fig. 7, item 1) on the arbor
(Fig. 7, item 2) and raise it until the fastening holes of
wheel guard and wheel guard arbor coincide.
•Insert the M10 setscrew (Fig. 7, item 3) with washer
(Fig. 7, item 4) from below, and tighten the hexagon
nut (Fig. 7, item 5) and washer.
The wheel guard inuences the following modes of op-
eration:
- The measuring run is started by closing the wheel guard
(code C13).
- The wheel is braked on lifting the wheel guard during a
measuring run (code C5).
These modes of operation can be changed either permanent-
ly, or only as long as the machine is switched on, by means of
codes (see § 10. Changing modes of operation).
3. Electrical connection
Electrical standard equipment and drive motor of the wheel
balancer are provided for operation on 50/60 Hz, 115-120 V.
The connecting cable of the machine is designed as a
separate power cord. For connection to the power mains the
cable is provided with a NEMA 5-15P (U.S.) or C22.2 No. 42
(Canada) plug.
Fusing is by the customer before the plug connector, using a
15 amp circuit breaker.
The electrical diagram is illustrated in § 16.
The machine operates internally on a line voltage of 230 V
because the voltage is regulated by an integrated transformer.

Turning on the machine
5. Turning on the machine
When switched on by the switch (Fig. 17, item 1) the
electronic unit performs a number of self-tests. On successful
completion of these tests a melodious three-tone signal is
given. OK is read out on the displays, and the code number of
the program version is briey viewed on the display; then both
displays show wheel dimensions which were entered before
and are still stored in the electronic memory.
As long as the machine is carrying out the self-tests, no inputs
and no other operations whatsoever must be made. During
this starting phase the machine must not be subjected to even
the slightest vibration.
The electronic unit is factory-adjusted to the following modes
of operation, which are available after turning on:
- car wheel with nominal dimensions in inches width 6.5“
and diameter 15.0“
- entry of rim data in inches
- display of amount of unbalance in 1/4 ounce increments
- suppression of minor unbalance readings (limit set to
1/4 ounce)
- automatic braking of wheel when guard is opened during
the measuring run
- compensation of adapter unbalance switched off
- start of measuring run by START key only
Error codes at power on
If an error code occurs it must be acknowledged by pressing
the STOP key. No audible signal is given.
The following malfunction codes may occur at power-on:

3 Fastening screw (width across ats 14 mm)
• Before tting the wheel adapter clean the cone of the
main shaft (Fig. 28, item 1) and the inner cone of the
wheel adapter.
•Slide the wheel adapter onto the cone of the main shaft
so that the head of the hexagon socket head cap screw
attached to the end of the cone engages with one of
the recesses in the basic body of the adapter (Fig. 28,
item 2).
•Tighten the wheel adapter using the fastening screw
(Fig. 28, item 3).
6.2 Performing a compensation run
All clamping and centring means are balanced in our works to
within a certain tolerance.
To compensate for any residual unbalance that might be left
in the clamping means, it is recommended that an electrical
compensation run be performed (also see § 10. Changing
modes of operation). This mode cannot be transferred into the
permanent memory.
This mode of operation is retained until deleted via code C4,
by starting an Pro-Match run or readjustment, or by switching
off the machine.
•Press and hold the CODE key (Fig. 10, item 6) and
rotate the main shaft to set C4 in the display.
•
Press the START key.
The compensation run takes longer than a regular measur-
ing run. Once the compensation run is completed, C4 is read
out in the left display, 1 is read out in the right display, and the
compensation LED (Fig. 13, item 12) appears in the middle.
When another clamping means is used:
•
Repeat the compensation run.
or
•cancel compensation by pressing and holding the FINE
key (Fig. 11b, item 11) and rotating the wheel, or by
switching the machine off for a few seconds.
In the right display, 0 is read out.

Entry of balancing mode and wheel size
7. Entry of balancing mode and wheel
size
For determination of unbalance the following inputs have to be
made:
-balancing mode (weight tting position on rim)
-wheel size (wheel width and diameter)
-distance between machine and left correction plane
The wheel dimensions to be entered are usually given on the
rim. Rim diameter is also given on the tire.
Rim width is entered by pressing and holding the relative
function key (Fig. 31, item 2) and rotating the wheel until the
desired value is read out. On releasing the function key the
input is retained until another input is made.
The distance between left correction plane/machine and the
rim diameter are usually entered using the integrated gauge
arm, but may also be entered by pressing and holding the
relative function keys (Fig. 31, items 1 and 3) and rotating the
wheel until the desired values are read out. On releasing the
function key the input is retained until another input is made.

Entry of balancing mode and wheel size
7.1 Balancing modes
The use of different types on a standard (alloy) wheel and the
resulting different tting positions of the weights on the rim
produce differences between the rim data which have been
entered and the actual correction dimensions.
Fig. 32 Possible positions of the balance weights
- nominal rim data / actual correction data
1 Nominal rim dimensions to be entered
2 Actual correction data (center of gravity of weights) which
are used for determination of unbalance
The mode chosen is read out on the display, showing the
relative rim symbol (Fig. 33), or on the digital displays when
the Alu key is pressed (reading e.g. Alu 1).
•Press and hold the Alu key (Fig. 33, item 1) and rotate
the wheel to set the desired balancing mode (weight
tting positions - Fig. 33).
•Release the Alu key as soon as the desired mode is
read out.

7.2.2 Gauge head applications
In order to be able to determine unbalance in a single measur-
ing run, the rim dimensions have to be entered correctly.
Fig. 36 shows correct application (with and without adhesive
weight) of the gauge on various rims and for various weight
positions. There are either one, or two positions where the
gauge has to be applied.
