Troubleshooting Tips for When Your JLG Boom Lift Won’t Move

The cause of the JLG boom lift not moving needs to be diagnosed and addressed.

Jlg Boom Lift Won’T Move

If a JLG boom lift won’t move, it is likely due to a fault in the hydraulic or electrical system. The most common causes of immobility are identified through troubleshooting techniques that are easy to follow. Start by checking the hydraulic fluid level, examining hydraulic and electrical lines, and tightening all hydraulic connections. If the more basic fixes don’t resolve the issue, it may require more advanced repair techniques such as removal and inspection of the cylinder eyes or replacing broken electrical connections. For severe cases where total replacement of components is necessary, contacting a certified JLG technician may be the best option.

What Causes a JLG Boom Lift to Not Move?

A JLG boom lift may not move for a variety of reasons. The most common causes are an issue with the electrical system, worn or damaged parts, lack of lubrication, or incorrect operator settings.

Electrical Systems

The electrical system of a JLG boom lift can be complex and may require troubleshooting to identify the exact cause of any issues. Faulty wiring and connections, bad switches or components, and low battery power can all be potential causes of an electrical issue that would prevent the lift from moving. If you are having trouble with the electrical system, it is important to consult your owners manual and/or contact a qualified technician for assistance.

Worn or Damaged Parts

The movement of a JLG boom lift is powered by hydraulic motors and pumps that can become worn or damaged over time. Worn hydraulic cylinders, hoses, pumps, motors, filters, seals and other components can lead to problems with the operation of the lift. It is important to regularly inspect all parts for signs of wear and tear and replace them as needed in order to keep your lift running properly.

Lack of Lubrication

Regular lubrication is essential for keeping your JLG boom lift functioning properly. Without proper lubrication, components may become stuck or seize up due to friction and heat build-up caused by metal-on-metal contact. It is important to check your owners manual for specific instructions on how often you should lubricate each component on your lift. If in doubt, it is best to consult a qualified technician.

Incorrect Operator Settings

The operator settings on a JLG boom lift can also have an impact on its ability to move. Improperly set controls can lead to problems with acceleration or deceleration that could cause the lift to stall out or not move at all. It is important that you understand how each control works and make sure they are set correctly before attempting to operate your lift.

What is a JLG Boom Lift?

A JLG Boom Lift is an aerial work platform that is used to provide temporary access to areas that are otherwise inaccessible. The lift operates on a four-wheel drive base and has multiple articulating arms or booms that can be extended up to eight feet in height. It can be used to reach heights of up to 40 feet, making it ideal for construction, industrial, maintenance and repair applications.

Common Causes of JLG Boom Lift Won’t Move

There are a number of reasons why a JLG Boom Lift may not move. Some common causes of this include:

  • Low Battery Power: The lift may not have enough power to move if the battery charge is low or the connections are loose.
  • Damaged Motors: The motors that power the wheels may be damaged or malfunctioning, preventing them from turning.
  • Blocked Wheels: Objects in the way can block the wheels from turning, preventing the lift from moving.
  • Faulty Electrical Connections: Issues with electrical connections can prevent the motor from receiving power or cause it to malfunction.

Troubleshooting Steps

If your JLG Boom Lift won’t move, there are several troubleshooting steps you can take to try and fix the problem. These include:

  • Check the Battery Charge:

    Check the battery charge level and make sure it’s fully charged. If it isn’t, charge it until it is. If there are loose connections, make sure they’re properly connected.


  • Inspect for Damage:

    Inspect all of the motors for signs of damage or wear and tear. If any damage is found, replace them with new parts.


  • Clear Objects Away From Wheels:

    Check around all four wheels for objects that could be blocking them from turning. Clear any objects away if necessary.




  • Test all of the electrical connections between components to make sure they’re functioning properly.
