No action when the 1. manually presses the control panel button
Reason:
1 Power cord fault
2 The fuse is blown
3 Motor failure
Methods:
1 Check whether the AC220V power supply is normal
2 Replace the fuse of the same model
3 Replace the starting capacitor or repair the motor
2. column cannot rise or rise slowly
Reason:
1 Oil supply system is not smooth
2 safety valve closed lax
3 safety valve is too loose
Methods:
1 Check the oil pipe to ensure that there is no water leakage
2 Close the safety valve
3 Fine adjustment safety valve
Slow drop of 3. cylinder
Reason:
1 Oil supply system is not smooth
2 safety valve is too tight or too loose
Methods:
1 Check the oil pipe to ensure that there is no water leakage
2 Fine adjustment safety valve
4. column has the phenomenon of falling
Reason:
1 Manual safety valve is too loose
2 Hydraulic oil leakage
3 Hydraulic lock failure
Methods:
1 Close the safety valve
2 Clean up the oil leakage and add hydraulic oil
3 Replace the hydraulic lock
Daily maintenance:
1 During operation, prevent continuous rise and fall. The lifting cannot be continuously switched at high speed, which is easy to shorten the service life of the motor and hydraulic pump.
2 Check the oil level of the oil tank regularly. If the oil level is lower than the bottom line, you should refuel; if the color of the oil page becomes dark and cloudy, you should consider replacing the oil page.
3 When there are vehicles or pedestrians on the road, they should be lifted strictly to avoid injury.
4 Adhere to the smooth drainage at the bottom of the lifting road pile and clean the surrounding area to ensure the service life, performance and waterproof sealing of the lifting road pile.
5 In the case of heavy ice and snow, if the pile is severely frozen, the lifting should be stopped and heated after freezing.
