9. HYDRAULIC LIFTING GEAR
			0
9.1 GENERAL
Cut-out pressure, pressure switch	160 bar
Pre-set value, pressure relief valve	180 bar
Maximum admissible system pressure	200 bar
Test pressure, lifting cylinder	220 bar
Delivery line while lifting	Line connection B
Delivery line while lowering	Line connection A
	(The characters are printed on the pump unit)
Safety device	Once the trailing axle has been lowered, it can
	only be lifted again after approx. 2.5 minutes. If
	the control switch is put into the "lifting" position
	before approx. 2.5 minutes has elapsed, the
	lifting gear will not be activated and the time relay
	will be reset. In that case you will have to wait
	about another 2.5 minutes before the trailing axle
	can be lifted.

0
		The tightening torques stated in this section are
		different from the standard tightening torques
		stated in the overview of the standard tightening
		torques. The other threaded connections not
		specified must therefore be tightened to the
		torque stated in the overview of standard
		tightening torques.
		When attachment bolts and nuts are replaced, it
		is important that - unless stated otherwise - these
		bolts and nuts are of exactly the same length and
		property class as those removed.
