Their scissor lifts are prized for their versatility, height capabilities, and ease of use, making them a common choice for workers needing to access elevated work areas safely. This article will dive into the details of JLG scissor lifts, including key features, common troubleshooting issues, and essential maintenance tips. Whether you are a first-time user or an experienced operator, understanding how these machines work and how to keep them in top shape can make a huge difference in their performance and longevity.
1. Key Features of JLG Scissor Lifts
JLG scissor lifts come in various models designed for specific tasks. However, all scissor lifts from JLG share certain key features that make them effective in a wide range of industries.
1.1 Lift Capacity
JLG scissor lifts are designed to carry heavy loads to significant heights. Depending on the model, these lifts can carry anywhere from 500 to 2,000 pounds of equipment and personnel. This makes them ideal for tasks that require both vertical reach and the ability to carry tools, materials, or equipment to the work area.
1.2 Height Reach
One of the most important features of any scissor lift is its height capability. JLG scissor lifts can reach impressive heights ranging from 20 feet to over 40 feet. The extended platform allows workers to perform overhead tasks safely without the need for ladders or scaffolding.
1.3 Electric vs. Diesel Models
JLG offers both electric and diesel-powered scissor lifts. Electric models are preferred for indoor use due to their quiet operation and lack of emissions. They are often used in warehouses, retail environments, and facilities with low ceilings. On the other hand, diesel models are used for outdoor applications or rough terrain, providing more power and endurance in challenging environments.
1.4 Platform Size and Extension
JLG scissor lifts come with varying platform sizes, offering flexibility depending on the nature of the task. Some models feature extendable platforms, allowing for more working space while still maintaining stability and safety. This feature is particularly helpful when working on larger construction sites or in situations where additional space is required for materials or tools.
2. Troubleshooting Common JLG Scissor Lift Issues
While JLG scissor lifts are built for durability and efficiency, like any piece of machinery, they can experience problems over time. Understanding common issues and knowing how to troubleshoot them can save valuable time and reduce the risk of major breakdowns. Here are some common problems operators may face:
2.1 Lift Not Operating or Moving
If your JLG scissor lift isn’t moving or operating as expected, it could be due to several reasons:
When the platform of a JLG scissor lift jerks or sticks during ascent or descent, it is often a sign of:
When operating in tight spaces, poor steering performance can be a real challenge. If a scissor lift is not steering correctly, it could be due to:
To ensure long-lasting performance and safety, regular maintenance is essential for JLG scissor lifts. Proper upkeep not only enhances the lifespan of the lift but also reduces the likelihood of breakdowns during operation.
3.1 Routine Inspections
Regular inspections should be performed to check for signs of wear, leaks, or damage. Key areas to inspect include:
A clean scissor lift performs better and lasts longer. Dust, dirt, and debris can clog hydraulic systems and sensors. Regularly clean the machine, especially around moving parts, to maintain optimal performance.
3.3 Lubrication
Lubricating the moving parts, including the scissor arms and pivot points, will reduce friction and wear. Using high-quality lubricant will also protect against rust and corrosion.
3.4 Seasonal Preparation
Before using the lift in extreme weather conditions, ensure that it is prepared for the challenges ahead. For example:
JLG scissor lifts are powerful, versatile, and durable machines that can be adapted for many industries, from construction to warehouse management. By understanding their key features, troubleshooting common issues, and maintaining the machine properly, operators can maximize the efficiency and lifespan of these lifts.
Regular maintenance, inspections, and addressing minor issues before they become major problems can help avoid downtime and costly repairs. The ability to work at heights safely and efficiently is crucial for many tasks, and with the right care, a JLG scissor lift can continue to provide excellent performance for years to come.
In short, whether used indoors or outdoors, JLG scissor lifts are a valuable asset to any operation, and understanding their workings is essential for anyone who uses or maintains one.

While JLG scissor lifts are built for durability and efficiency, like any piece of machinery, they can experience problems over time. Understanding common issues and knowing how to troubleshoot them can save valuable time and reduce the risk of major breakdowns. Here are some common problems operators may face:
2.1 Lift Not Operating or Moving
If your JLG scissor lift isn’t moving or operating as expected, it could be due to several reasons:
- Battery Issues: A common cause for failure in electric models is low or dead batteries. If the lift isn’t moving, check the battery charge and connections. Replacing the batteries or ensuring they are fully charged can often resolve this issue.
- Faulty Hydraulic System: If the lift works intermittently or fails to raise, a hydraulic issue could be at play. Check the hydraulic fluid levels and look for any leaks in the system. Low hydraulic fluid can prevent the lift from functioning correctly.
- Fuses and Electrical Connections: Blown fuses or loose wiring can cause the lift to stop functioning. Ensure all fuses are intact and that wiring connections are secure.
When the platform of a JLG scissor lift jerks or sticks during ascent or descent, it is often a sign of:
- Hydraulic Problems: A dirty or clogged filter can restrict the flow of hydraulic fluid, causing the platform to move unevenly. Regularly replacing filters and checking for leaks can prevent this issue.
- Dirty or Faulty Sensors: Many models have sensors that monitor the position of the platform. These sensors can become dirty, leading to erratic movements. Cleaning or replacing sensors can resolve the issue.
- Overloading: Exceeding the maximum weight capacity can also cause jerking movements. Always ensure the lift is not overloaded.
When operating in tight spaces, poor steering performance can be a real challenge. If a scissor lift is not steering correctly, it could be due to:
- Faulty Steering Controls: The steering mechanism may become worn or damaged. Inspect the controls to ensure they are working properly.
- Low Hydraulic Pressure: Steering in some models relies on hydraulic power. If the pressure is too low, the lift may become difficult to maneuver.
To ensure long-lasting performance and safety, regular maintenance is essential for JLG scissor lifts. Proper upkeep not only enhances the lifespan of the lift but also reduces the likelihood of breakdowns during operation.
3.1 Routine Inspections
Regular inspections should be performed to check for signs of wear, leaks, or damage. Key areas to inspect include:
- Battery: Check battery charge levels, and clean the terminals regularly to prevent corrosion.
- Tires: Inspect tires for wear and tear, ensuring that they are properly inflated.
- Hydraulic System: Check for leaks, and ensure fluid levels are correct. Regularly clean filters and inspect hoses for damage.
- Brakes and Steering: Ensure the braking system and steering controls are functioning properly. Test the brakes for responsiveness and check for any signs of fluid leakage in the system.
A clean scissor lift performs better and lasts longer. Dust, dirt, and debris can clog hydraulic systems and sensors. Regularly clean the machine, especially around moving parts, to maintain optimal performance.
3.3 Lubrication
Lubricating the moving parts, including the scissor arms and pivot points, will reduce friction and wear. Using high-quality lubricant will also protect against rust and corrosion.
3.4 Seasonal Preparation
Before using the lift in extreme weather conditions, ensure that it is prepared for the challenges ahead. For example:
- In cold weather, make sure the hydraulic fluid is suitable for low temperatures to prevent the system from freezing.
- In hot weather, check the engine and hydraulic systems for overheating.
