 Danger !

Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities.

No parts of the body or limbs should be within the operating area of mechanical components when moving components.

AS00.00-Z-0009-01A

Preparation

1

Drive vehicle onto measuring station

 The wheel alignment check must be carried out on a horizontal, level and clean base. An alignment check bay with a workshop pit is a substantial advantage.

2

Move vehicle to driving level

 See operator's manual. Ensure there is a sufficient supply of compressed-air throughout the entire measuring procedure.

3

Check air pressure of tires when axle is under no load, and correct if necessary

 See vehicle manufacturer's technical specifications.

4

Check and adjust wheel bearing play
