	Removing
1.1	Extract oil from supply reservoir of power steering pump	Models 129, 140, 202, 208 with and without level control, model 210 without level control or ADS	Figure
2.1	Clamp off feed line from reservoir	Model 210 with level control or ADS	Figure
3	Unscrew high-pressure expansion hose (30i) from power steering pump	On vehicles with tandem pump, the tester must not  be connected to the radial piston pump
4	Connect tester (039) between power steering pump and high-pressure expansion hose (30i)	Tester	Fig 3
		Connection	Fig 4
		Connection	Fig 5
		Connection for power steering pumps with O-ring seal on pressure hose	Fig 8
5.1	Remove clamp from feed line from reservoir	Model 210 with level control or ADS	Figure
6	Top up reservoir	Models 129, 140, 208, models 202 up to 31.8.95	AP46.00-P-4611BA
		Models 170, 210, model 202 as of 1.9.95	AP46.00-P-4611BB
	Risk of accident  from vehicle starting off by itself when engine is running. Risk of injury  with bruises and burns if you hold your hand in the engine when it is being started or while it is running.	Secure vehicle to prevent it moving off by itself. Wear closed and close-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
7	Engine ON
8	Increase engine speed to approx. 1000 rpm
	Inspecting
9	Close throttle cock (70b) and check maximum service pressure	Perform the test quickly to prevent the oil temperature from rising too high
