Altec is recalling 477 2016-2022 Digger Derrick units because relay connectors reattached to the wrong plug can leave the hydraulic overload protection system unable to work.

What's wrong?
The hydraulic overload protection system on 2016-2022 Altec Digger Derrick units is the safeguard that limits hydraulic operation when the boom or derrick is overloaded. It uses pressure signals and a time delay relay, a small electrical control that tells the system when to respond instead of reacting to every brief pressure change.
During stability testing, connectors for that relay were removed so the hydraulic overload protection system was bypassed for the test. On included units, those connectors were reattached to the wrong plug. With the relay plugged into the wrong connection, the overload protection system does not activate as designed, even though the system parts remain installed.
The operator still has a warning sign to watch. The load indicator gauge or pressure gauge at the operator's station continues to work and rises into the overload region when the unit lifts more than its capacity allows. That gauge behavior is the sign to stop lifting and have the connections checked.
Who's affected?
Spans the 2016-2022 Digger Derrick line, with the same time delay relay tied to the boom control wiring.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
When the overload protection system does not work, the operator can overload the unit without realizing it, increasing the risk of injury. Watch the load indicator gauge and pressure gauge, which still rise into the overload region when capacity is exceeded. Schedule the inspection soon. Repair is free at any franchised Altec dealer.
What should I do?
- Check your VIN to confirm your 2016-2022 Altec Digger Derrick is included in this recall.
- Contact a franchised Altec dealer to schedule the free relay-connector inspection and reattachment that restores the hydraulic overload protection system.
- Reference recall number 22V349 and Altec recall CSN 858 when you call.
- Bring the recall notice if you have it, and ask Altec customer service at 1-877-462-5832 any scheduling questions.
- Avoid operating the digger derrick under load until Altec confirms the overload protection connectors are attached to the correct plugs.
What happens at the repair
At the dealer, an Altec technician inspects the relay connectors for the hydraulic overload protection system and reattaches any connectors that are on the wrong plug. The inspection and any needed repair are free under the recall. If you already paid to fix this problem before the recall notice, Altec's Warranty Policy covers reimbursement for the related repair cost. Contact Altec customer service and ask what paperwork is needed for that claim.
