JT40/JT40 All Terrain Operator’s Manual
Sensor Override
Sensor Override
Automated functions of the JT40/JT40 All Terrain are made possible by communication between five
electronic controllers onboard the unit. Sensor Override Mode permits limited operation without automated
functions and standard equipment protections. In Sensor Override Mode, an operator can complete a bore
and move the unit away from the jobsite so that proper repairs can be made at a Ditch Witch
®
dealership.
If a sensor affected by Sensor Override Mode has an error and needs attention, a pop-up message will
appear. Each pop-up message will give the operator the option to override the error. This table explains
how automated functions are affected in Sensor Override Mode both if overridden by the operator and if
not overridden.
NOTICE: Some automated functions that protect components from damage are NOT available in
Sensor Override Mode. Use extreme caution when operating in Sensor Override Mode.
IMPORTANT: Only a qualified Ditch Witch
®
service technician can return the unit to normal operation.
Contact your Ditch Witch dealership.
