Where the leveling cylinder attaches to the arm, it can crack near the counter sunk grease fitting and over time fatigue and fail.
Consequence
If the arm fails, the platform movement is not controlled and may dump the platform occupants.

DEFECT #2 - EQUIPMENT
Posted on: 2007-01-04
Description
Certain terex telelect digger derricks and aerial devices equipped with check valves with p/nos engraved on the valve of; 1904f, 1908f, 1910f, and 1910r. These valves can fail which can cause the parts to move through the hydraulic system or will allow a vacuum to form in hydraulic lines if the pump flow should stop. These devices are installed on trucks to transport the aerial device or digger derrick to the work site to facilitate working on electrical power lines and communication lines or to trim trees.
Consequence
Failure of the check valve can result in unexpected boom platform movement after the control lever is returned to the neutral position, or allow vacuum to form in hydraulic lines to the boom tip and could cause potential dielectric failure, possibly resulting in death or serious injury.
Corrective Action
Terex utilities will notify owners and replace the check valves free of charge. The recall began on march 22, 2007. Owners may contact terex utilities service department at 1-605-882-4000.

DEFECT #3 - EQUIPMENT
Posted on: 2008-01-25
Description
Terex is recalling 1,167 tc series aerial devices equipped with check valve, p/n 443847, installed from september 2001 until march 2007. The valve is located on the lower boom lift cylinder. Failure can occur only when the vehicle is parked and the aerial device is in operation. The check valve is used in retiming of the boom when the platform is out of level. The flow through the check valve can cause the snap ring to fail if the retiming flow is abnormally high. The check valve components will flow into the lift cylinder if the snap ring fails.
Consequence
Debris may scratch the cylinder wall or get into holding valves and cause the platform to drift down slowly, which could possibly result in serious injury or death to the platform user.
Corrective Action
Terex will notify owners and replace the defective check valves free of charge. The recall began on february 7, 2008. Owners may contact terex utilities warranty department by calling 1-605-882-4000.
