in particular before fitting the quick-clamping holders.
^
Strictly comply with maintenance intervals for measuring equipment and measuring platform. If the levelling of the measuring platform or of the
measuring area is done in-house, levelling equipment is required. A hose level is inadequate!
^
Skilled handling of measuring equipment and measuring platform..
^
Sliding plates with transverse motion (rotary motion) at the rear axle are advisable.
^
Observe the Technical Literature of PAG, the manufacturer of the measuring equipment and the manufacturer of the measuring platform..
^
Do not treat measured values as a whole, but very critically in regard to driving dynamics, high-speed strength of the tyres, tyre wear and
cost/benefit effects (time required for correction of insubstantial deviations). The toe values are of decisive significance for driving dynamics and
tyre wear.
^
If the vehicle is measured front and rear, check and adjust the wheel alignment values at the rear axle first. Camber values at the front axle apply
for the straight-ahead position of the wheels. Steering wheel and steering gear in centre position when toe is being adjusted.
^
Before wheel alignment values are adjusted at front and rear axles, it is recommended that the vehicle height be checked at the empty weight.
Conclusions can then be drawn about wheel alignment values in the event of any suspension alignment that becomes necessary later.
Vehicle height (vehicle height check)
General
^
The vehicle height at front and rear axle is not adjustable.
^
The check points for the vehicle height can be found in the following description.
Preliminary work
1. To carry out height check, position ready-to-drive vehicle (fully tanked with tyre repair kit or spare wheel and tools) on a flat surface or on the
measuring station. In the case of vehicles with air suspension, the normal vehicle level must be set. The vehicle normal level must be set from the
low level. Normal level means: Start the engine so that the compressor is running. If there is sufficient air in the pressure tanks, the engine does not
need to be started. Tap the right-hand rocker switch on the centre console in the appropriate direction until vehicle has reached low level. Then set
the vehicle normal level. The middle indicator light next to the rocker switch is on permanently. If a further indicator light should come on, a
different level is adjusted.
2. To avoid controlling the level of air suspension during the alignment, switch the level control off during alignment and switch it on again after
work has been completed.
3. Compress vehicle at front and rear by approximately 25 mm 2-3 times and allow it to spring back freely.
Rear axle
The measurement is made from the wheel contact area to the bottom edge of the side member suspension subframe -A- (in front of drain bore at
connection point control arm to suspension subframe).
Front axle
The measurement is made from the wheel contact area to the bottom edge of the side member -A- of front axle suspension subframe (between camber
and caster eccentric).
