Fault example:	Fault example:	Method of exclusion:
1. Cannot rise	1.1 Is the hydraulic oil insufficient?	Unscrew the oil pump filling screw (Figure 2 ). Just add N46 hydraulic oil to the screw hole position.
	1.2 The oil drain valve stem does not exit	Use needle-nosed pliers to pull out the drain valve stem (Figure 2 ) to reset the drain valve arm.
	1.3 There are impurities in the main oil passage hole.	Open the main oil passage hole, use a suction iron to suck out the impurities and then assemble them in sequence.
