INSTRUMENTS AND CONTROLS FOUR-WHEEL CRAB STEERING “4WS CRAB” (to be used in building sites to position the machine for different applications) The four-wheel crab steering mode allows the steering wheel to control the front and rear wheels at the same time and in the same direction to perform cross movements to the right or to the left. The four-wheel crab steering can be selected only with the machine at rest and changing over from two-wheel steering to four-wheel crab steering is possible only if the 1st, 2nd or 3rd gear is engaged and after the front wheels have been aligned (LED 5 on).
NOTE q The four-wheel crab steering cannot be selected when the 4th gear is engaged; the selection of the four-wheel crab steering with 4th gear engaged triggers the acoustic alarm that signals that the manoeuvre is not correct. q If the 4th gear is engaged with four-wheel crab steering selected, the acoustic alarm sounds and the general alarm warning light on the front dashboard comes on (see"3.3.1 pos. 9 - GENERAL ALARM WARNING LIGHT"). q If the travel speed is higher than 10 km/h in 3rd gear, the acoustic alarm signals that the safety limit has been exceeded; the alarm stops as soon as the speed is brought below 10 km/h.
q Changing over from the four-wheel steering modes to two- wheel steering is possible even while the machine is moving and only after the rear wheels have been realigned (LED 6 on). 17/18 - STABILIZER CONTROL LEVERS q Before moving the machine, make sure that the stabilizers are completely raised. q When travelling on roads, raise the stabilizers and engage the safety locks and the servo control locking device. These levers are positioned to the operator’s left and control the raising and lowering of the stabilizers, as indicated in the diagram. IMPORTANT q All movements are inhibited when the safety button (A) is in locking position (LED on) (see "3.3.2 pos.
12 - SERVO CONTROL LOCKING BUTTON"). 106 WARNING
