hand lamp matches the receiver’s channel. No equipment that might also re-
spond to this channel may be located anywhere on the premises. The unin-
tended operation of other equipment may put people at risk.
Furthermore, no transmission equipment that could respond to the axle play
detector may be located anywhere on the premises.
•To prevent injuries caused by impact or being run over, a sufficient safe dis-
tance from the vehicle to be tested must be maintained when it is being driven
onto and off the test equipment.
•Before testing, the vehicle to be tested must be secured against rolling away.
When used on sloped surfaces (e.g. access ramps in mobile test lanes), it is
advisable to have someone man the driver’s cab during testing so they can re-
spond to unintended movements.
•Wear personal protective equipment.
•A sufficient safety distance from the surface of the test plates’ movement area
must be maintained. Risk of crushing and shearing!
•Test plates must not be walked on, even when not in use. There is a risk of fall-
ing due to unexpected test plate movements. There is a risk of slipping due to
water or ice on the test plates.
•During operation avoid lateral shifting of the vehicle on the test plates and con-
tinually monitor the position of both wheels on the test plates. Should the
wheels move close to the edge of the test plates, stop the test immediately and
reposition the vehicle.
•Periodically check the fastening screws of the test plates for tight fit.

NOTICE
Check package to ensure it is complete, in accordance with the order confirma-
tion. Report any transport damage to the carrier immediately.
During loading, unloading and transport always use suitable lifting equipment, ma-
terial handling equipment (e.g. cranes, forklifts, etc.) and the right load handling
attachments and slings. Always ensure that the parts to be transported are sus-
pended or loaded properly so that they cannot fall, taking into account size,
weight and the centre of gravity.
Store the packages in a covered area, protected from direct sunlight, at a low
humidity and with temperatures between 0...+40 °C (32…104 °F). Do not stack
packages.
When unpacking, take care to avoid any possibility of injury or damage. Keep at a
safe distance when opening the package strapping, do not allow any parts to fall
out.

Installation and Initial Operation
WARNING
Installation and initial operation of the equipment may be done only by authorized
and trained service technicians provided by the manufacturer, licensed dealers or
service partners.
WARNING
Before connecting the power supply, make sure that an external, lockable EMER-
GENCY-STOP MAIN SWITCH is used. This must be provided by the customer
and installed in the power supply line to the control.
The EMERGENCY-STOP MAIN SWITCH must meet the requirements of
EN ISO 13850.

Operation
5.1
Main Switch
DANGER
The main switch is used as emergency switch. In case of emergency immediately
turn it to position 0!
Main switch in position 0
Lift is disconnected from power supply
Main switch in position 1
Lift is ready for operation
5.2
Preparing for Operation
Examine the danger zone and ensure that warnings are legible. Damaged or illegi-
ble warnings and markings must be replaced immediately.
When operating an axle play detector in a mobile test lane, it must be ensured that
all the hydraulic components’ covers are fitted and do not show any signs of
damage that would restrict functionality or signs of poor attachment.
If light conditions vary a great deal between test objects and peripherals (e.g.
when used in mobile test lanes outdoors), sufficient lighting or glare protection
must be provided.
A sufficiently ergonomic positioning option must be provided for performing the
test (particularly for vehicle testing in mobile test lanes).
WARNING
•Test plates must not be walked on, even when not in use. There is a risk of fall-
ing due to unexpected test plate movements. There is a risk of slipping due to
water or ice on the test plates.
•During operation avoid lateral shifting of the vehicle on the test plates and con-
tinually monitor the position of both wheels on the test plates. Should the
wheels move close to the edge of the test plates, stop the test immediately and
reposition the vehicle.

13
BA010101-en
5.3
Operating the Axle Play Detector
WARNING
•The hand lamp must be carried in such a way that eliminates the risk of unin-
tentional operation of the axle play detector. For safety reasons, it is advisable
to stay within the axle play detector’s field of vision and danger zone when us-
ing the hand lamp.
NOTICE
•The hydraulic unit must never be left running for longer than absolutely neces-
sary, as the pump can become damaged otherwise.
•The hand lamp must be protected against shocks to ensure that the light bulb
has a long service life.
•Some types of axle play detector are equipped with a synchronisation switch
on the control box which enables control of the plates’ lengthwise and/or
crosswise movement.
•If the plates are moved back and forth in the direction of travel, the brake must
be applied as the turning wheels would otherwise follow the plates’ move-
ments.
•Attempts should always be made to cause the vehicle wheel to slip onto the
plates, as this is the best way to detect incorrect axle play.
1 Switch the test device on at the main switch.
2 Drive the vehicle to be tested onto the test plates at walking speed and secure
it against rolling away, e.g. apply the parking brake or use chocks.
3 The testing plates can be operated using the hand lamp’s push-button
functions.
4 Switch the light and the hydraulic unit off after testing.
5 Drive the vehicle off the test plates.
6 Place the hand lamp in the charging holder to charge.

Service Mode
To remove the sliding plates, the hydraulic cylinders must be pressure relieved. To
do this, a Service mode was integrated. When this mode is enabled, only the
valves are driven as in the normal operating mode. The hydraulic pump remains
OFF.
Enable Service Mode
•Cable hand lamp: Push and hold rocker buttons A and B together for
10 seconds. The pump switches off. (Simultaneous actuation of A1 and B1 or
A2 and B2).
Once the second button is detected, the valves are switched off. The pump
remains ON until 10 seconds have elapsed. The plates remain in their last posi-
tion.
•Radio hand lamp: Set to mode LED ON (Manual operating button). To enable
the Service mode, push and hold the operating button for 25 seconds.
During this time period, the valve is ON and the pump is also ON. After
25 seconds the pump switches OFF. The valve remains ON.
Function while Service Mode is Enabled
When in the Service mode, the valves of the corresponding moving directions can
be driven using the operating buttons, and the plates can be moved by hand.
On the MAH CAN RP circuit board the Service mode is indicated by the yellow
LED of VD20.
Quit Service Mode
•Cable hand lamp: Push and hold rocker buttons A and B together for
10 seconds. The output for the pump switches ON and the Service mode is
quit.
•Radio hand lamp: Set to mode LED ON. Push and hold the operating button
for 25 seconds to quit the Service mode. After 25 seconds the pump switches
ON.
Alternatively, the Service mode can be quit by switching off the power supply.
