The JLG 60G is a high-reach lift platform used in construction, maintenance, and various other industries where elevated work is necessary. Built for durability and reliability, the 60G model from JLG is equipped with multiple platform controls to manage the lift's movements, including the ability to extend and retract the boom, rotate the platform, and adjust the height. However, as with any heavy machinery, malfunctions can occur, leading to frustration and downtime.
A common problem experienced by owners and operators of the 1984 JLG 60G is when certain platform controls stop working, leading to limited functionality. Understanding the causes behind this issue and how to fix it is essential for restoring full use of the equipment and minimizing downtime.
Overview of the JLG 60G Lift
The JLG 60G is a 60-foot (18.3-meter) aerial work platform designed for heavy-duty lifting tasks. It features a telescoping boom, offering significant reach and flexibility for tasks such as building maintenance, tree trimming, or any other elevated work. The platform is powered by a hydraulic system that controls both the boom and platform movements, ensuring smooth operation across a wide variety of conditions.
This model was introduced during the 1980s, a period when many of the aerial lift platforms were evolving from basic designs into more sophisticated hydraulic systems. While JLG (John L. Grove) was already a key player in the lift industry, the 60G exemplified their focus on reliability and versatility.
Common Issues with Platform Controls on the 1984 JLG 60G
When certain platform controls fail to work, it can be related to a few common issues within the machine's electrical or hydraulic systems. These issues may range from simple wiring problems to more complex hydraulic malfunctions, and pinpointing the exact cause is vital.
1. Faulty Electrical Connections
A malfunction in the electrical system is one of the most common reasons for non-functioning platform controls. Wiring issues, faulty relays, and loose connections can all interfere with the proper operation of the platform controls. Electrical problems might manifest as unresponsive controls, intermittent control operation, or even complete failure of specific functions.
The JLG 60G utilizes hydraulic systems to power its boom, platform, and other key functions. If certain platform controls stop working, it could be a sign of a hydraulic issue. This can include low hydraulic fluid levels, a clogged filter, or problems with the hydraulic pump or valves.
The control panel itself could be the culprit. Given the complexity of the electronics in modern lifts, a problem within the control panel could prevent specific functions from responding. This might include damaged switches, worn-out buttons, or an issue with the control board.
The solenoids and valves play a significant role in controlling the movement of the platform and boom. If these components malfunction, it can lead to certain controls not working, such as the inability to extend the boom or adjust platform tilt.
Sometimes, the failure of platform controls can be linked to environmental factors, such as extreme temperatures or exposure to moisture. These elements can affect both the electrical and hydraulic systems, particularly if the lift has been exposed to harsh weather conditions.
To avoid issues with the platform controls in the future, regular maintenance and inspections are critical. Here are some preventive steps to ensure the lift’s platform controls remain functional:
Dealing with non-functional platform controls on the 1984 JLG 60G lift can be a hassle, but understanding the potential causes and solutions can help get the machine back up and running efficiently. From electrical problems to hydraulic malfunctions, a systematic approach to troubleshooting and regular maintenance will ensure that the 60G performs reliably on job sites. Always ensure the machine is regularly checked, serviced, and properly stored to avoid unnecessary downtime and maximize its lifespan.

Wiring issues, faulty relays, and loose connections can all interfere with the proper operation of the platform controls. Electrical problems might manifest as unresponsive controls, intermittent control operation, or even complete failure of specific functions.
- Possible Causes:
- Loose or corroded connections.
- Blown fuses or faulty relays.
- Wiring damage, such as frayed or broken wires.
- Loose or corroded connections.
- Solution:
- Inspect all electrical connections, especially around the control panel and platform.
- Check the fuses and relays for any signs of damage or wear and replace them if necessary.
- Ensure that all wires are securely connected and free from any visible damage.
- Inspect all electrical connections, especially around the control panel and platform.
The JLG 60G utilizes hydraulic systems to power its boom, platform, and other key functions. If certain platform controls stop working, it could be a sign of a hydraulic issue. This can include low hydraulic fluid levels, a clogged filter, or problems with the hydraulic pump or valves.
- Possible Causes:
- Low or contaminated hydraulic fluid.
- Clogged or dirty hydraulic filters.
- Malfunctioning hydraulic pump or valves.
- Leaks in the hydraulic lines or connections.
- Low or contaminated hydraulic fluid.
- Solution:
- Check the hydraulic fluid levels and ensure they meet the manufacturer’s recommended specifications. If the fluid appears dirty or contaminated, perform a fluid change and replace the filter.
- Inspect the hydraulic lines and seals for any leaks and repair them as needed.
- Test the hydraulic pump and valves for proper operation, and replace any faulty components.
