The main function of the outriggers is to give the machine stability. They must always be used when working with the machine. DXR250 Dozer blades The main function of the dozer blades is to give the machine stability. They must always be used when working with the machine.
Direction control valves direct the hydraulic oil to the machine’s different functions. The hydraulic pump is of the variable displacement type and delivers a flow of DXR250, DXR270: 0-65 l/min (0-17 gal/ min) DXR300, DXR310: 0-75 l/min (0-20 gal/min).

ELECTRICAL SYSTEM General The electric system consists of a high-voltage circuit and a low-voltage circuit. High-voltage circuit High-voltage is used as a power source for both the electric motor and the low-voltage circuit. An automatic phase rotation change-over switch ensures that the electric motor has the correct rotation direction.
CONTROL SYSTEM What is what on the remote Right joystick Pressure/flow to hydraulic tool (hammer/cutter) control? 10 Flow to machine movement/speed Left joystick 11 Stop button motor Left joystick - left button 12 Main switch Left joystick - right button 13 Machine stop Menu buttons 14 Start button motor...
CONTROL SYSTEM General Battery The remote control, the electronics unit and the pilot The battery is a Li-ion type. Operating time is about 8-10 control valves are the main components in the control hours per charge. Extreme cold impairs the battery’s system.
MACHINE´S SAFETY EQUIPMENT General Identity code The remote control and the machine are connected by In this section the machine’s safety features and their means of a pre-programmed ID code. The ID code function are explained. Concerning inspection and ensures that the right remote control is used for the right maintenance, see the instructions under Maintenance machine.

MAINTENANCE AND SERVICE Oil filter CAUTION! Allow the machine to cool. Hot oil can cause severe burn injuries. • Undo the air filter so that the overpressure in the tank is discharged. • Thoroughly clean the outside of the filter and the surrounding parts.
TROUBLESHOOTING Error messages There are two types of error messages that can appear on the display: • Service messages - These messages do not represent any direct danger for the operator or the machine. • Warnings - These warn of faults or safety defects that can cause mechanical damage. All acknowledged fault messages remain as small yellow or red warning triangles in the service field and can be accessed by going to the service menu and selecting 'Warnings'.
