	Checking
	Risk of death  caused by vehicle slipping or toppling off of the lifting platform	Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer.	AS00.00-Z-0010-01A
	Notes on AIRmatic		AH32.22-P-1000-02RT
1	Open engine hood and raise to vertical position		AR88.40-P-1000RT
2	Spray pressure line connection on the valve unit (Y36 or Y36/8) with leak detection spray	Wait approx. 10 to 15 minutes after spraying. This allows smaller leaks to be detected (bubbles form). Larger leaks are visible immediately. In the event of a defective pressure line connection on the valve unit (Y36 or Y36/8): ↓
