Emergency reverse switch
To protect the operator from becoming pinned against an obstacle by the control handle,
an emergency reverse switch is provided at the end of the control handle. If this switch is
pressed during operation, the truck will move off in reverse. The mechanical brake will then
engage to stop the truck. The travel control must then be returned to neutral before the truck
can again be operated.
