12 - SERVO CONTROL LOCKING BUTTON
WARNING
q
When travelling on roads, always engage the servo control
locking device.
This button has the function to inhibit the servo controls and must
be used when the machine travels on roads and as safety lock
when leaving the driver’s seat or parking the machine.
To lock the servo controls, press the button (12) (LED on). Press
the button again (LED off) to release the controls.
NOTE
q
Whenever the machine is started, the controls are locked
automatically (LED on); press the button (LED off) to use the
controls.
q
For safety reasons, the servo controls are locked automatically
(LED on) when the seat is rotated by the operator to change
driving position. The servo controls are automatically released
(LED off) when the rotation has been completed and the seat is
fixed in the correct driving position (front or rear).
q
In the version with backhoe servo controls, this button serves to
lock the backhoe controls, too.
13 - BACKHOE SPEED CONTROL BUTTON
This button allows the quantity of oil delivered by the hydraulic
pump to be selected. Whenever restarted, the machine
automatically selects the POWER mode (LED on), even if when it
stopped the selected mode was ECONOMY. This position makes
it possible to use the maximum oil delivery and is indispensable
for a correct use of the backhoe. When the button is pressed
(LED off), the ECONOMY operating mode is selected. To return
to the POWER mode (LED on), press the button again. The
machine passes automatically from POWER to ECONOMY mode
when the forward or the reverse gear are engaged (reverse gear
lever forward or backward). To return to the POWER mode, shift
the lever back to the neutral position.
14 - BACKHOE SLIDING LOCK SWITCH
This switch has the function to release the backhoe unit from the
sliding guides, in such a way as to make it possible to change the
position of the backhoe with respect to the machine. The backhoe
unit is generally fixed on the guides and the switch is not operated
(LED off). When pressed, the switch comes on and releases the
unit from the guides, thus allowing the backhoe to slide; once the
desired position has been reached, press the switch again to fix
the backhoe unit (LED off).
