The T350 and T500J boom lifts are designed to provide safe and efficient access to work areas. They feature a variety of safety features, including an emergency stop button, a load limit indicator, and a platform safety gate. These boom lifts are also equipped with a powerful hydraulic system that allows them to lift heavy loads and maneuver easily in tight spaces.

Emergency stop button
Load limit indicator
Platform safety gate
Powerful hydraulic system
Easy to maneuver
The emergency stop button is used to immediately stop the boom lift in case of an emergency.
The load limit indicator will light up if the boom lift is overloaded.
The boom lift has a variety of safety features, including an emergency stop button, a load limit indicator, and a platform safety gate.
What could be the cause if the device does not level?
Potential causes related to leveling functions include: Ground Leveling Not Functioning Properly; Platform Leveling Up/Down Function Inoperative; Level Down Solenoid Open Circuit; Level Down Solenoid Short To Battery; Level Down Solenoid Short To Ground; Level Up Solenoid Open Circuit; Level Up Solenoid Short To Battery; Level Up Solenoid Short To Ground. Check Level Up/Down Switch and Leveling related messages.
What should be checked if experiencing issues with ground level functionality?
When experiencing issues with ground level functionality, consider: Ground Controls Inoperative; Ground Leveling Not Functioning Properly; Ground Reference for voltage measurements; Ground Module Power.
What are the common diagnostic codes for a Power Module Failure?
Flash code OFF or 3 indicates a short circuit or controller damage. Code 1 indicates a personality range error. Codes 2 or 11 indicate internal errors. Code 10 indicates a CANBUS communication failure, and code 8 indicates the module is overheating.
Which fault codes indicate a need to check power circuits or the MOSFET?
Troubleshooting the power circuits or checking for a MOSFET short circuit is required when User Fault Code 9, Service Fault Code 9-9, Power Module Flash Code 'Off', or Flash Code 3 is observed.
