If you encounter issues with your Genie scissor lift not lifting, it’s crucial to follow a systematic troubleshooting process to identify the cause and resolve the problem. Below are the key areas to check, along with potential solutions.
1. Check the Power Supply
Before diving into more complex troubleshooting steps, ensure that the scissor lift has power. The lift might not operate if there is an issue with the battery, wiring, or power connections.
Many scissor lifts, including Genie models, are equipped with an emergency stop button. If this button has been accidentally engaged, it will prevent the lift from operating.
A common reason for a scissor lift not lifting is an issue within the hydraulic system.
The lift may not raise if it detects an overload condition. Many scissor lifts are equipped with a system that prevents lifting if the platform is overloaded.
If the lift still fails to operate after checking the basic components, it might be an issue with the control system or wiring.
The motor may not be functioning properly, which can prevent the lift from moving. This could be due to electrical or mechanical failure.
By methodically checking the power supply, emergency stop button, hydraulic system, overload protection, and control systems, you can identify and resolve most issues causing a Genie scissor lift not to lift. If these troubleshooting steps do not resolve the issue, consulting a professional for further inspection may be necessary.
1. Check the Power Supply
Before diving into more complex troubleshooting steps, ensure that the scissor lift has power. The lift might not operate if there is an issue with the battery, wiring, or power connections.
- Battery Check: If the battery is dead or discharged, the lift will not operate. Check the battery voltage using a multimeter. A fully charged battery should read around 12 volts. If the voltage is low, recharge the battery or replace it if necessary.
- Wiring: Inspect the wiring for any visible damage or loose connections. A broken or disconnected wire can prevent the lift from receiving the necessary power.
Many scissor lifts, including Genie models, are equipped with an emergency stop button. If this button has been accidentally engaged, it will prevent the lift from operating.
- Reset the Emergency Stop: Check if the emergency stop button has been pressed. If so, release it and attempt to operate the lift again.
A common reason for a scissor lift not lifting is an issue within the hydraulic system.
- Low Hydraulic Fluid: Ensure that the hydraulic fluid level is adequate. Low fluid levels can cause the lift to malfunction. Check the reservoir and refill with the manufacturer-recommended hydraulic fluid if needed.
- Hydraulic Leaks: Inspect the hydraulic hoses, fittings, and seals for leaks. A loss of hydraulic fluid due to a leak will affect the lift’s ability to function properly.
The lift may not raise if it detects an overload condition. Many scissor lifts are equipped with a system that prevents lifting if the platform is overloaded.
- Weight Limit: Ensure that the lift is not carrying more weight than its rated capacity. Remove any excess load and try again.
- Overload Indicator: Some models will display an overload warning light or sound an alarm when an overload is detected. Ensure this indicator is not activated.
If the lift still fails to operate after checking the basic components, it might be an issue with the control system or wiring.
- Control Circuit: Examine the control circuit and the control panel for faults. Look for any blown fuses or damaged components that may prevent the lift from responding.
- Solenoid Valve: A malfunctioning solenoid valve can prevent the hydraulic fluid from flowing properly. Test the solenoid valve and replace it if necessary.
The motor may not be functioning properly, which can prevent the lift from moving. This could be due to electrical or mechanical failure.
- Electrical Connections: Check the motor’s electrical connections. Loose or corroded connections can interrupt the power supply to the motor.
- Motor Inspection: If the motor is receiving power but not working, the motor itself may be faulty. It may require repair or replacement.
By methodically checking the power supply, emergency stop button, hydraulic system, overload protection, and control systems, you can identify and resolve most issues causing a Genie scissor lift not to lift. If these troubleshooting steps do not resolve the issue, consulting a professional for further inspection may be necessary.
