1. General
While selecting the location for the balancer always consider the regulations and instructions of
the Accident Prevention & Insurance Assocation as well as the requirements of the national
working regulations.
The wheel balancer can be located on each flat ground. A fastening of the machine is not
compulsory. For balancing wheels with a weight of more than 40kg, everything is prepared to fix
the machine with dowels on the ground.
Because of logistical reasons the wheel balancing machines are fragmented in their main
components and packed in special cartons.
The main components are:
- Machine including mid centring device mounted
- Touch PC (for BM x5 – types only)
- Wheel cover/hood
- Weight tray (for BM x5 – types including monitor boom)
- Carton with documentation, Weight pliers, wheel weight removal tool, cones, quick nut (clamping
sleeve for QuickSpan

models), pressure cup for steel wheels, distance ring
2. Assembling the machine
The unpacking, built up and the mounting should be done practically by 2 persons.
After put up and fixing the machine, it has to be positioned on the 3 marked points. If this is not
the case, this has to be compensated with special parts which have to be lay underneath the
marked points (the machine has to be positioned on this points).
Lift up the machine on the pallet and turn it 180° around a corner. Then dump it on the ground.
Pull out the pallet underneath the machine and position the machine smoothly.
Make sure that the mid centring device is mounted correctly and the 2 red dots (1 on the shaft and
1 on the mid centring device) are in line to each other as shown in the picture below

3. Mounting the wheel hood
The wheel hood is shipped completely assembled including the shaft and wheel hood switch. It is
mounted with 4 screws to the cabinet of the wheel balancer.
The screws are packed in the bag together with the instruction manual.
View from top View from inside of cabinet
The connecting cable of the wheel hood switch has to be routed through the bore holes in the
cabinet and the connection plug has to be connected to J 5 on the display board (see chapter. 4.)
For wheel balancer versions with an outside arm the connecting cable has to be connected to
J 12 as described in the drawing on the display board.

4. Mounting the weight tray and the LE Display
The weight tray is fixed to the cabinet with 4 pieces of duck tape that is already present on the
lower side of the weight tray as well as on the cabinet.
Guide the cables for the LE Display through the hole in the weight tray and mount the weight tray
to the cabinet
The plugs on the cables and the connectors on the display board are marked with numbers which
are also printed on the circuit board. Because of the special form/ design of the connector, it is
guaranteed that they cannot put on in a wrong way.

5. Mounting the Touch PC
The basic balancing board where the connectors for the wheel hood switch and for the outside
arm (if present) have to be connected is located inside the cabinet
Guide the serial cable and the power supply cable through the monitor boom and mount the
weight tray to the cabinet
Connect the 2 cables as shown in the picture below
Fix the Touch PC with the screw to the top of the monitor boom

6. Putting the machine into operation
In order to set the machine into operation several general steps are required. The information on
the service functions can also be found in the instruction manual
DIGITAL WHEEL BALANCERS
Via the function key you get into the menu for service functions to select the basic
settings or change them according to the user’s requirements. The various menu functions from
F1 to F14 can be selected by pressing the +- keys
When you are in the function menu, an „Fn“ is shown on the left side of the digital display. The
chosen function is shown on the right side of the digital display.
Once a particular function is desired, it can be chosen by pressing the function key again
Perform the following steps in the order stated below
F 5 Calibration
The calibration weight supplied with the machine must be used
together with the clamping adapter. Make sure that the threaded hole
on the adapter is in line with the red indicator marking on the main
shaft.
For calibration the calibration weight (1987009WG3) is required
MACHINES with manual clamping of the wheel
Remove cone and clamp from the main shaft.
MACHINES with QuickSpan

:
Attach the pressure cup for steel rims to the clamping
sleeve and activate the QuickSpan

Press the function key to select the function menu.
Use +/- keys to select the Function 5.
Press function key again to activate the function.

F2 Zero run
The Zero run is provided to electrically compensate the unbalance of the adaptor or clamping
means.
Whenever the clamping means has been dismounted and replaced a compensation of the
residual unbalance in the adapter and clamping means should be carried out.
Routine:
MACHINES with manual clamping of the wheel
Remove the cones and clamp from the adaptor.
Press the function key to select the function menu.
Use +/- keys to select the Function 2.
Press function key again to activate the function.
Press START to start the run.
The residual unbalance of the adaptor is calculated and saved in the
memory. (This value stays in the memory even after switching off the
power). After the run has finished, the program automatically changes
to normal mode.

F 6 Autorun
If Autorun is active (ON) the balancing run is started when the wheel guard is closed. If Autorun is
not active (OFF) the balancing run needs to be started by pushing the START button when the
wheel guard is closed.
