Terex South Dakota, Inc. (Terex) is recalling certain TLM aerial-device vehicles equipped with external holding valve blocks. The incorrect holding valve was installed on the upper boom cylinder base end. As a result, if the hose for the upper boom raise function should burst while at maximum load and maximum side reach, the boom may drift down.
Uncontrolled movement of the boom can increase the risk of an injury.
Terex will notify owners, and dealers will replace the base end holding valve on the upper boom lift cylinder, free of charge. The recall began October 25, 2019. Owners may contact Terex customer service at 1-844-837-3948. Terex's number for this recall is SN675.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
