If you experience problems operating any controls, turn off your SINGAR radio unit. Failure to
comply may result in death or injury to personnel and/or damage to equipment.
Electronic controls, devices, and systems may be susceptible to electromagnetic interference (EMI) if inadequately shielded or
otherwise configured for electromagnetic compatibility. When operating any of the vehicle's controls while the SINGAR
radio is on, EMI could occur. If you notice controls not responding correctly, or at all, turn your SINGAR radio off.
The backhoe assembly is operated with hydraulic pressure supplied by the vehicle's hydraulic system. The operator controls
the functions of the backhoe, using two joystick controls that are incorporated into the armrests of the operator's seat. The
backhoe is automatically powered. Controls are activated whenever the operator's seat is turned to face the backhoe; however,
an override switch enables the backhoe to be operated when the operator's seat is facing forward.
