Equipment 2017-05-15 · campaign 17V320000 · 58 vehicles
Defect: Terex South Dakota (TSD) is recalling certain 2007-2016 vehicles equipped with Terex C4000, FC, HR, HRX, SCM, TC, TCX, TL, TPL, and XT aerial devices and digger derricks used for utility line work. In the event of a short circuit of a tool plugged into the onboard electrical socket, the GFPE breaker may not trip at the proper current before the user receives a shock.
Risk: Without proper protection against electrical shock, the user has a greater risk of injury.
Fix: TSD will notify owners, and dealers will replace the breakers with GFCI breakers that will trip at a lower current, free of charge. The recall began on June 27, 2017. Owners may contact TSD Customer Service Department at 1-800-982-8975. TSD's number for this recall is SN658.
Electrical System 2017-05-15 · campaign 17V321000 · 444 vehicles
Defect: Terex South Dakota (TSD) is recalling certain 2012-2017 Digger Derricks and Aerial Devices, models C4000, C5000, C6000, C7000, General, HR, OM, RM,RMX, SC, SCM, TC, TCX, TL, TM, and XT, built on Freightliner chassis with SmartPlex engine controls. The vehicles have a switch to monitor whether the hood is open or not. If the switch thinks that the hood is open, the vehicle software may disable the Aerial or Digger Derrick remote engine control functions.
Risk: If the hood switch prevents the remote engine controls from shutting the vehicle engine down in the event of a hydraulic issue on the Aerial or Digger Derrick, it may increase the risk of an injury.
Fix: TSD will notify owners, and dealers will reprogram the vehicles to only disable the engine start function if the switch indicates that the hood is open, free of charge. The recall began on June 28, 2017. Owners may contact TSD Customer Service Department at 1-800-982-8975. TSD's number for this recall is SN659.
