Komatsu — 3.3.6.2 MACHINE CONTROLS (version with servo-assisted backhoe)

INSTRUMENTS AND CONTROLS 9 - BACKHOE SLIDING LOCK SWITCH The switch (9) has the function to release the pressure necessary to lock the backhoe unit, so that the backhoe can slide on the guides. With released switch (LED off) the backhoe unit is fixed on the guides. With pressed switch (LED on) the backhoe unit is released and can slide on the guides. IMPORTANT q The switch (9) loses its specific function when the safety button (B) is in locking position. For further details, see "3.3.2 pos. 12 - SERVO CONTROL LOCKING BUTTON". q Before starting any operation, make sure that the backhoe is fixed on its guides. 10 - DECLUTCH PUSH BUTTON q Do not use this button for more than 15–20 seconds.

q Do not use this button during travel on roads and especially when travelling downhill, since this function releases the clutch and sets the machine in neutral. The push button (10) is used when the machine is used as a loader; the declutch function serves to change all the engine power into the hydraulic power necessary to lift the material. 101 CAUTION WARNING
