	2. Leakage occurs to the check valve.	Remove the screws and spring. Knock the small steel balls lightly to force out the airtight surface.
	3. Leakage occurs to other position.	Trace the problem and correct.
Insufficient oil cylinder pressure.	The spring of safety valve breaks down.	Replace the safety valve .
The pipe escapes.	1. Improper direction and height of bracket.	Vary the direction and height of bracket.
	2. Improper direction of steel pipe.	Toggle the clock-wise / anti-clockwise switch to change the rotation direction of spindle.
