Recall 26V310 covers 213 2020-2026 Altec aerial device vehicles for E-stop control wiring defects. Repair will be free at any franchised Altec dealer once available.
Altec is recalling 213 2020-2026 aerial devices, including the Ta Series Aerial Device, because the ground level emergency stop can fail to stop hydraulic functions when the machine is in ePTO mode. That delay increases the risk of injury, and the Altec dealer repair will be free once the remedy is available.

What's wrong?
The ground level emergency stop on affected 2020-2026 Altec aerial devices is the lower-control safety switch that is supposed to stop machine movement in an emergency. On these units, that switch has to work with the hydraulic controls, the system that raises, lowers, and moves the aerial device. It also has to work when the machine is in ePTO mode, which powers hydraulic operation without normal truck power flow.
The problem is in the control wiring. Altec found incorrect wiring and an incorrect wiring-harness design in the electrical schematic. Because of that wiring path, pressing the ground level emergency stop does not stop hydraulic functions while the unit is in ePTO mode. Updated wiring changes the circuit so the emergency stop shuts those functions down.
There is no warning sign before failure. An operator will not see a light, hear a sound, or feel a change that shows the ground emergency stop will fail to stop hydraulic movement in ePTO mode.

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 ground-level E-stop is pressed and hydraulics keep moving, a worker near the equipment faces an increased risk of injury. There is no warning before this failure, so operators should schedule the recall work and keep people clear of moving components during use. Repair will be free at any franchised Altec dealer once available.
What should I do?
- Check your VIN to confirm your 2020-2026 Altec Ta Series Aerial Device, An Series Aerial Device, L Series Aerial Device, Am Series Aerial Device, At Series, Lr Series Aerial Device, or Aa Series Aerial Device is included in this recall.
- Wait for Altec's owner letter scheduled for July 10, 2026, before scheduling the free inspection and E-stop wiring test.
- Call Altec customer service at 1-877-462-5832 with questions and reference recall number 26V310 (Altec recall CSN-3322).
- Limit use in ePTO mode until the inspection is complete; the ground level E-stop can fail to stop hydraulic functions if the wiring is incorrect.
- Schedule the free inspection, E-stop function test, and wiring update once Altec opens the remedy.
What happens at the repair
Once the repair opens, an Altec technician will inspect the unit and test the ground level E-stop function while the machine is in ePTO mode. If the wiring is incorrect, the technician will update it. The final dealer repair will be free once available, with parts and labor covered under the recall. Altec uses its general reimbursement plan on file for eligible owners who already paid for a related repair. Keep repair invoices and payment records, then ask Altec customer service how to submit documentation under that plan.
