Recall 25V909 affects 18 2022-2023 Altec AA55, AM55, AN46, and AN55 vehicles for a missing boom-hose check valve. Repair is free through Altec service.
Altec is recalling 18 2022-2023 AA55, AM55, AN46, and AN55 vehicles because a missing boom-hose check valve can let a vacuum form and reduce upper-boom insulation. Reduced insulation can conduct electricity to the operator or others touching the vehicle, increasing the risk of injury and death, and Altec dealers will complete the repair free of charge.

What's wrong?
The hydraulic in-line check valve on the 2022-2023 Altec AN55, AA55, AM55, and AN46 is a small valve in the boom's hydraulic system. Its job is to hold oil in the boom hoses at the rotary joint, where hydraulic lines route fluid as the aerial equipment moves. Keeping oil in those hoses helps the upper boom keep its intended insulation.
On affected vehicles, that check valve was not installed. Without the valve, oil drains out of the boom hoses and a vacuum forms in the hydraulic line. That vacuum reduces the upper boom's insulation, so the boom no longer has the same protective separation the system was designed to provide.
There is no warning sign before failure. The owner or operator should not expect a normal-use symptom that confirms the valve is missing. The issue requires inspection of the hydraulic system and installation of the missing check valve.
Who's affected?
Covers four Altec aerial-device models across the 2022 and 2023 model years, all tied to the hydraulic in-line check valve in the motor/hydraulic pump system.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
There is no warning before reduced insulation allows electricity to reach the operator or someone touching the vehicle. That exposure increases the risk of injury and death, so keep people clear of energized equipment and arrange inspection and repair promptly. Repair is free at any franchised Altec dealer.
What should I do?
- Check your VIN to confirm your 2022-2023 Altec AA55 or 2023 Altec AN55, AM55, or AN46 vehicle is included in this recall.
- Contact Altec customer service at 1-877-462-5832 to arrange the free inspection and repair.
- Schedule Altec service to inspect for the missing boom-hose check valve and install it free of charge if it is missing.
- Reference recall number 25V909 and Altec recall CSN 3272 when you call.
- Avoid boom operation near energized equipment until the inspection and any check-valve installation are complete.
What happens at the repair
At Altec service, an Altec technician inspects the vehicle to confirm whether the check valve is installed in the boom hose system. If the valve is missing, Altec service installs the check valve free of charge under the recall. The check valve helps retain oil in the boom hoses so a vacuum does not reduce the upper boom's insulation. Altec uses its general reimbursement plan on file for eligible prior repairs, so bring documentation for any related out-of-pocket work to the service desk.
