Terex South Dakota Inc. is recalling 28 2015-2016 model-year C5000, C6000, General 80, RMX, TM100, and TM125 aerial devices and digger derrick lifts installed on trucks manufactured from Aug. 4, 2015, to Feb. 16 of this year.
In the affected trucks, the suspension circuit can inflate the suspension air bags if the master/PTO switch or ignition is turned off in the cab while the boom is in the raised position, the National Highway Traffic Safety Administration reported. This can cause the frame to rise, lifting the outrigger from the ground and leading to truck instability.
Terex dealers will install a second outrigger-enable relay, free of charge, to resolve the problem. Owners can reach Terex customer service at (800) 982-8975. Terex's number for this recall is SN636.
