MODEL

668.3, 670.3/4

 Danger !	Risk of death caused by limbs being caught or crushed by rotating parts when performing tests on the brake test stand	Never leave the vehicle unattended on the rollers except in an emergency. Ensure that no one is under the vehicle or near rotating parts during testing. In case of emergency, use the EMERGENCY OFF switch to shut down test stand.	AS42.00-Z-0001-01A
 Danger !	Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.	Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
	Check
1	Connect pressure gauge to compressed air connections of master brake cylinder for 1st and 2nd axle	 Test kit	*360589002100
2	Start engine and completely fill compressed air system at idle speed
3	Switch roller brake test stand on
4	Drive the vehicle on the roller brake test stand	 Run engine.
5	Using the brake pedal, apply the specified test pressures to the brake cylinder and compare brake forces achieved for each axle against the reference values.	Minimum brake force on 1st axle at test pressure	*BE42.10-N-1001-17I
		Minimum force on 2nd axle at test pressure	*BE42.10-N-1002-17I
		If the brake forces are not achieved:
		
		Determine causes and repair brake system.
6	Drive the vehicle off the roller brake test stand.
7	Apply parking brake
8	Turn off engine
9	Switch roller brake test stand off
10	Remove all pressure gauges
