Once the test lane has been properly switched on, (paragraph 3.2.1) and ready for testing, the
test procedure can start.

Slowly and straight ahead drive front axle over side-slip test plate onto test plates of shock
absorber tester. Avoid any steering motions.
→
Left pointer indicates side-slip in m/km.
→
Measurement value is automatically stored.
→
Side-slip value measured later for rear axle will be also automatically stored. If test plates
are driven over several times values will be overwritten in this order.
Prepare shock absorber test
Vehicle axle to be tested is on test plates of shock absorber tester.
a) Release brake.
b) Place gear shift to neutral.
1 Wheel must be straight and in centre on test plate to avoid measuring errors (especially
important when test lane is equipped with FWT suspension tester). Wheel to be tested must
not be blocked by brakes or gear shift.
Weight will not be displayed as described in point 4 if an additional weighing device is
integrated in the brake tester.
3 Weight display
Axle weight is displayed once vehicle is on test
plates.
Example: left display indicates 32 % or Mm and
right display 33 % or Mm.
→
Axle weight left is 320 kg, right 330 kg.
Weight can be displayed on shock absorber
scale or brake tester scale. Setting by MAHA-
service.
4 Shock absorber test
Once vehicle is on shock absorber test plates first left-hand and then right-hand plate will
start vibrating.
→
Once right-hand plate reaches standstill both measurement results will be displayed.
Never exit shock absorber plates when they are still vibrating. This can result in
equipment damage.
