What to do if LINCOS STD-5335A Scissor Lifts lift with light load but not with heavy load?
If your LINCOS Scissor Lift experiences normal lifting with a light load but fails with a heavy load, the safe pressure setting of the over-flow valve may need adjustment. Slightly turn the set knob rightward to increase the pressure. Additionally, the spool of the lowering solenoid valve may be stuck due to dirt, requiring cleaning.
Why are the safety pawl not released form the safety teeth on my LINCOS STD-5335A?
If the safety pawls on your LINCOS Scissor Lift are not releasing from the safety teeth, it could be due to a blocked “antiknock valve”. Remove the “antiknock valve” from the oil supply hole at the bottom of the oil cylinder and clean it.
How to correct the motor direction on LINCOS STD-5335A?
If the motor on your LINCOS Scissor Lift turns in reverse, change the phases of the power supply wires.
What to do if the “antiknock valve” is blocked on LINCOS STD-5335A Scissor Lifts?
If the “antiknock valve” for preventing oil pipe burst is blocked on your LINCOS Scissor Lift, remove or close the air supply pipe, which will lock the safety pawl of the machine without lifting it. Then, remove the “antiknock valve” from the oil supply hole at the bottom of the oil cylinder, and clean the “antiknock valve.”
What to do if the solenoid air valve does not work on LINCOS STD-5335A?
If the solenoid air valve on your LINCOS Scissor Lift is energized but not opening the air loop, you should check or replace the solenoid air valve.
What to do if the lowering solenoid valve is energized but does not work on LINCOS STD-5335A Scissor Lifts?
If the lowering solenoid valve on your LINCOS Scissor Lift is energized but not working, check the plug and coil of the valve, and ensure the end copper nut is tightened correctly.
Why is the safety pawl not lifted on my LINCOS STD-5335A?
If the safety pawl on your LINCOS Scissor Lift is not lifting, the air pressure may be insufficient, the safety pawl may be stuck, or the air pipe may be broken. Adjust the pressure, check the air pipe, and replace it if necessary.
What to do if the AC contactor does not pick up in LINCOS STD-5335A Scissor Lifts?
If the AC contactor in the motor circuit of your LINCOS Scissor Lift does not pick up, try forcing the contactor down with an isolation rod. If the motor then operates, inspect the control circuit. If the voltage at both ends of the contactor coil is normal, replace the contactor.
What to do if the amount of hydraulic oil is not enough in LINCOS STD-5335A?
If your LINCOS Scissor Lift has insufficient hydraulic oil, add more hydraulic oil.
What to do if the hydraulic oil has too high viscosity in LINCOS STD-5335A Scissor Lifts?
If the hydraulic oil in your LINCOS Scissor Lift has too high viscosity, is frozen, or has deteriorated (especially in winter), replace it with hydraulic oil according to the instruction book.
