The JLG TOUCAN DUO lift may not descend due to several possible reasons:
1. Shelf Sensor Activation – The shelf elevation movement is interrupted by the shelf sensor, which may be preventing descent. 2. Lifting Chain Tension – If the lifting chains do not have identical tension, the mechanism may not function properly. 3. Back-Up Cables – Cables on the side of the mast prevent chains from slacking, which could cause movement issues if not properly adjusted. 4. Mechanical Obstruction – Misalignment or an obstruction in the shelf or platform components could prevent movement. 5. Alarms or Warnings – The system may have detected a fault, requiring inspection of the alarms and warnings section for troubleshooting.
A qualified technician should inspect these components to determine the exact cause.

CHARACTERISTICS The JLG elevating work platform consists of a self- propelled all-welded steel frame, a telescopic mast and a platform. The platform is fitted with a motorised shelf enabling picking operations. The drive function is accomplished through two electrical motors propelling the rear axle. Steering (front axle) is accomplished by an electrical cylinder located on the chassis between the steering wheels.
Speeds are indicated for a machine with a fully charged battery operating at a 20°C ambient temperature. Constant product improvement make it necessary that JLG France SAS reserve the right to make specification and equipment changes without notice.
The safety of persons working on and around the work platform must be your prime concern. After repairs, the work platform can only return to service after a thorough functional check. All covers and protections must be installed. models TOUCAN Duo Updated 06-2015...
