Recall 23V525 covers 535 2022-2023 Altec Aerial Device and Digger Derrick vehicles for a missing AC circuit breaker. Repair is free through Altec.
Altec is recalling 535 2022-2023 Digger Derrick and Aerial Device units because affected power inverters lack a circuit breaker protecting the AC output circuit. Without that protection, the AC circuit can overheat and raise the risk of a fire; Altec dealers will complete the repair free of charge.

What's wrong?
The 2022-2023 Altec Aerial Device and Digger Derrick use a power inverter to change battery DC power into AC power for the 120-volt outlet. That outlet lets crews run AC tools or equipment from the vehicle's electrical system. A circuit breaker is supposed to protect the outlet circuit by opening when current rises above its set rating.
On the affected units, a specific inverter was installed without that circuit breaker on the AC output side. If the outlet circuit is overloaded, the protective breaker is not there to interrupt the current. The circuit can stay energized when it should shut off, leaving the outlet wiring without the intended overload protection.
There is no warning sign before failure. An operator should not expect a light, message, sound, or outlet change that confirms the circuit is unprotected.

What should I do?
- Check your VIN to confirm your 2022-2023 Altec Digger Derrick or Aerial Device is included in this recall.
- Contact Altec customer service at 1-877-462-5832 to schedule the free circuit-breaker installation that protects the AC output circuit from overheating.

- Avoid using the AC output circuit until the circuit breaker repair is complete.
What happens at the repair
At the dealer, an Altec technician installs a 20-amp circuit breaker in the AC circuit for the power inverter, so the AC output circuit has the required protection. The recall repair is free, and parts and labor are covered. Altec's Warranty Policy also covers the recall remedy when an owner already paid for a repair tied to this same problem before the recall notice. Keep invoices and repair paperwork, then contact Altec customer service or the service desk to submit the reimbursement claim.

Frequently asked questions
What is recall 23V525?
Recall 23V525 covers 535 2022-2023 Altec Digger Derrick and Aerial Device units with a power inverter AC output circuit that was installed without a protective circuit breaker. Without that breaker, the AC circuit can overheat and create a fire risk. Altec will install a 20-amp circuit breaker for free.
What should I do if my 2022-2023 Altec Digger Derrick or Aerial Device is on this recall?
Check your VIN to confirm whether your specific Altec unit is included in recall 23V525. If it is, contact Altec or an authorized Altec service location to schedule the 20-amp circuit breaker installation. Reference recall 23V525 and Altec CSN 3103 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Altec says it will install the 20-amp circuit breaker in the AC circuit free of charge.
What is the safety risk?
The safety risk is fire. The affected power inverter converts DC power to AC power, but the AC output circuit lacks the circuit breaker that protects it from overheating. Altec's repair adds that 20-amp circuit breaker.
When were owners notified about recall 23V525?
Altec mailed owner notification letters on December 21, 2023. If you own a 2022-2023 Altec Digger Derrick or Aerial Device and never received a letter, check your VIN and call Altec customer service at 1-877-462-5832 with recall 23V525 or CSN 3103.
