What's wrong?
On affected 1994-1997 Altec service vehicles, the aerial device uses a boom lift cylinder with part number 350-40094. This hydraulic cylinder is the force-making part that raises and holds the boom while the aerial device is being used. Pressurized hydraulic fluid moves inside the cylinder, and the cylinder turns that pressure into controlled lift.
The recalled cylinder was not built to tolerate frequent tensile loading. In plain terms, repeated pulling force on the cylinder can overload it over time. When that happens, the cylinder can fail instead of holding the boom as designed. That failure means the aerial device no longer has the hydraulic support it needs.
There is no warning sign before failure. Owners and fleet operators should not rely on a change in sound, motion, or boom feel to catch this problem before the cylinder fails.

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?
Failure of the lower boom lift cylinder can cause death or serious injury. If your unit is included, stop boom operation and arrange the recall repair promptly. Keep operators clear of lift use until Altec confirms the repair path for your specific unit. Repair will be free at any franchised Altec dealer once available.
What should I do?
- Check your VIN to confirm your 1994-1997 Altec service vehicle is included in this recall.
- Watch for Altec owner instructions if you do not have the recall notice, then call Altec with questions about the repair path.
- Contact Altec or a franchised Altec service location to schedule the free hydraulic-cylinder replacement that fixes the failure-prone lower boom lift cylinder.
- Bring the recall notice if Altec sent one. If not, reference recall number 10V610 when you call.
- Keep the aerial device out of service until the hydraulic-cylinder repair is complete.
What happens at the repair
The listed remedy is a hydraulic cylinder replacement. Once the dealer repair is available, an Altec technician replaces the boom lift hydraulic cylinders covered by recall 10V610, including cylinder part number 350-40094 on affected aerial devices. Parts and labor are covered under the recall. The filing does not give a repair time, so ask the service desk how long the vehicle needs to stay at the shop.
