According to the report, when the remote station was removed from the magnet this function then ceased.

Joy is re-investigating the effects of magnets on the Lightweight Station, and also what can be done to eliminate negative effects of a magnet of sufficient strength placed in proximity to the remote station.

In the meantime, Joy has strongly recommended extreme caution be exercised when using magnets around the Lightweight Remote Control Station and reiterates that normal

safe practices be used when operating with remote control. This includes observing the safe operating zones around the machine and not placing a powered remote station on a piece of energized equipment.

Joy has advised operators and management to refer to Joy’s Service Bulletin #00FG-0176 for additional information regarding remote control operation of Joy Equipment. To view this bulletin go to http://www.msha.gov/equiphaz.htm
