8. Troubleshooting. 

NOTE: If the problem can not be resolved locally, please do not hesitate to contact us for help. We offer our service as quickly 

as possible. To quickly solve a problem, we will provide as much information as possible, possibly photos of problem. 

Symptom 

Cause 

Resolution 

The engine does not work 

The power cable is not plugged 

in by the power outlet. 

Connect the power cable to the power socket. 

 

The AC contactor does not work. 

If  the  engine  works  by  forcing  the  contactor  with  an  isolation  rod, 
replace the contactor. 

The limit switch is not closed. 

Check the limit switch, its cable and adjust/ or replace the device. 

 

In lifting operation, the motor 

runs, but there is no lifting 

movement. 

The motor turns reverse. 

Modify the phases of the power cables 

Lifting with light load works 

normally but not with heavy load. 

The pressure of the overflow valve can be increased by turning the 

right knob slightly. 

The solenoid coil is defective and should be replaced 

 

The amount of hydraulic oil is 

not enough. 

Add hydraulic oil. 

When the "DOWN" 

button is pressed, the lift 

does not lower 

 

The descent valve is activated 

but it does not work 

 

Check the plug and spool of the drop valve, check the correct nut seal. 

Should it be replaced 

 

The Parachute Valve is blocked 

 

Remove the parachute valve from the oil supply hole at the bottom of 

the cylinder and clean the device. 

 

The lift lowers very slowly 

when subjected to weight 

loads in the standard range. 

 

Hydraulic oil has a high 

viscosity, is deteriorated or 

frozen (in winter) 

 

Replace the oil with an oil conforming to the operating manual.

 

The “antiknock valve”, inside the 

cylinders, is blocked. 

Remove the parachute valve from the oil supply hole at the bottom of 

the oil cylinder and clean the device or replace 

 

Platforms P1 and P2 are 

misaligned 

 

The air in the hydraulic circuit 

has not been completely 

removed.

 

Refer to page 18 "Oil Pressure Adjustment".

 

 

Oil leakages along the oil pipe or 

one of its joints. 

Check the sealing of the hydraulic circuit, then adjust the pressure and 
the level of the oil. 

 

The oil drain valve does not close 

properly 

 

Replace the oil drain valve, if necessary, add oil 

Noisy lifting and lowering

 

movements 

Lubrication is not enough 

Lubricate  all  pins  and  sliding  parts  (including  piston  rod)  with 
mechanical oil. 
 

The  floor  is  not  well  leveled  or 
the  base  of  the  lift  does  not 
adhere well to the floor. 
 

 

Adjust the leveling of the floor to properly adhere the lift to the floor.
