When Radio Signal is Lost, Don't Approach Remote Control Continuous Miners



If the remote control continuous miner is not following the commands of the radio remote control, DO NOT get within the machine's turning radius to get closer to the machine's antenna.

It is a common tendency to believe the radio control signal is not making it to the machine's antenna when the machine is not following the radio remote control commands.

First, check that the Remote Control Unit is powered up by the cap lamp battery, and then try the control command again.

If the machine does not respond, assume the machine or remote control unit has malfunctioned and proceed according to established company policies for maintenance and trouble shooting of the radio remote control equipment.
