Quick answer

The DB41B is a tracked, off road back yard derrick product. The upper boom extend function is intended to be disabled when the Hydraulic Overload Protection (HOP) system is activated. HOP activates correctly when the affected units are operated from the lower controls. However, Altec has discovered that upper boom extend is not disabled when HOP is activated while operating these units from the radio controls. This is caused by an issue with the derrick control system firmware. Altec requires the derrick control system firmware version to be inspected using the AXIS Service Interface and following the Inspection and Update Procedure beginning on page 2. If the inspection indicates that the derrick firmware version is incorrect, the firmware must be updated as described.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
