Service bulletin SIL 618

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Digger derricks using radio controls with load indicators (refer to Figure 1) have been found to sometimes allow the digger and the winch to operate at the same time possibly causing damage to one or both functions. A change has been made to the radio control module which eliminates the possibility of the two functions working together.
