Q There is no lift and no direction
A The problem has the following four factors: one is the hydraulic oil is not perfect; the second is the hydraulic pump intake pipe into the air; three is the quality of the hydraulic pump public pressure is not perfect; the fourth is the shunt valve blockage. The solution to the problem is that in the first case, and there are certain bubbles in the fuel tank hydraulic oil, mainly because of the air in the hydraulic pump oil hose. Tighten or replace the oil hose according to the tool. If the above problems do not appear, it can be clear that the hydraulic pump is not perfect or the shunt valve problem.

Q When you go there, the direction is too heavy
A The problem is mainly due to the shunt valve valve pin hairpin or the pressure is not perfect. Solve the problem is to adjust the shunt valve management direction of pressure, if the obvious effect is to shunt valve dismantling, according to the water sandpaper for effective grinding, after the valve core coated with certain hydraulic oil in the valve body for smooth adjustment, cannot card situation can be installation work, in order to effectively solve the problem.

Q The piston rod of the inclined cylinder extends automatically
A The problem is that the piston ring is unsealed or is worn out. The solution to the problem is to replace the inclined cylinder piston, and after the seal and dust ring on the guide cover, the inclined cylinder piston automatic, jitter, external oil leakage of the guide sleeve can be solved.
