Terex is recalling 42 2016-2017 Tlm aerial-device vehicles because an incorrect holding valve was installed on the upper boom cylinder base end.

What's wrong?
The Terex Tlm aerial device is mounted on 2016-2017 vehicles and lifts workers and tools while the vehicle is parked. The upper boom cylinder raises and supports the upper boom, and the holding valve is the hydraulic safety valve that helps keep that boom from drifting when hydraulic pressure changes.
On the included units, Terex installed the wrong holding valve on the base end of the upper boom cylinder. That valve has the wrong pressure setting for the upper boom raise function. If the upper boom raise hose bursts while the boom is carrying maximum load at maximum side reach, the valve does not hold the boom as intended, and the boom can drift down.
What you would notice is damage or failure at the upper boom raise hose before the drift condition develops. The holding valve itself is marked with its pressure setting, which helps service personnel identify whether the correct valve is installed.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
If the upper boom raise hose is damaged and fails, the boom can move without control and increase the risk of injury. Stop using the equipment if boom movement is abnormal or the hose shows damage, then contact the dealer. Repair is free at any franchised Terex dealer.
What should I do?
- Check your VIN to confirm your 2016-2017 Terex Tlm is included in this recall.
- Contact a franchised Terex dealer to schedule the free base end holding valve replacement that addresses boom drift after an upper boom raise hose burst.
- Bring the recall notice if Terex mailed one. If not, reference recall number 19V659 when you call.
- Avoid operating at maximum load and maximum side reach until the repair is complete.
- Call Terex customer service at 1-844-837-3948 with questions about scheduling or dealer instructions.
What happens at the repair
At the dealer, a Terex technician replaces the base end holding valve on the upper boom lift cylinder. The work addresses the incorrect holding valve installed on vehicles with external holding valve blocks. Parts and labor are covered under recall 19V659, so the repair is free. Use Terex recall number SN675 when you call the service desk, and confirm that the upper boom lift cylinder valve replacement is the repair being scheduled.
