1, the hydraulic oil tank is not enough, the oil pump suction air or oil filter is blocked by dirt will cause the oil pump oil shortage, resulting in the oil bubbles discharged from the impact of the blade.
The solution is to check the amount of oil, to prevent inhalation of air and cleaning filters.
2, hydraulic oil viscosity, increase flow resistance, need to replace the appropriate hydraulic oil.
3, due to oil pump or motor bearing or blade damage, coupling concentricity deviation caused by noise, to adjust concentricity or replacement parts.
4, the direction of the valve failed to respond but the function is still in, such as the valve core wear, leakage, burr blockage, mobility is not flexible, solenoid valve due to current failure and will produce
Born noise. The solution is to clean the valve core or replace the new parts, the current should be stable and sufficient.
5, hydraulic components damaged or oil pipeline obstruction, so that the flow of hydraulic oil to produce noise.
6, mechanical parts failure, lack of lubrication, loose parts, should find out the reasons for the fastening or replacement.
B, pressure plate does not fall, or not reset after descending
1, cutting switch problem, check or replace.
2, the oil tank or oil pipe leakage, fill or tighten the oil pipe joint.
3, solenoid valve can not be reset, repair or replacement.
4, poor contact relay, the main oil circuit can not switch, check the line.
C, don’t press down cutting pressure
1, oil pump damage or into the oil route plug, oil cylinder leak, check according to the situation.
2, micro switch touch too slow or fault, and regulate the cutting point in about 10mm before the touch or replacement.
3, solenoid valve failure, chaxiu solenoid valve spindle.
4, the fuel tank of the circulating oil is insufficient, to add circulating oil to the oil surface beyond the oil filter.
