Trouble Code (ALA)

Code fault description
 

ALA-5206

Starting switch transferred is ON, while the rise of the control lever is mounted in a position other than neutral.
 

ALA-5207

Starting switch transferred is ON, while the tilt control lever is set in a position other than neutral.
 

ALA-5208

Starting switch translated in the ON position at that time, as the lever 1 ATT working equipment control 1 is set in a position other than neutral.
 

ALA-5209

The starting switch is turned to ON, while the work equipment 2 control ATT lever 2 is set to a position other than neutral.
 

ALA-5210

The starting switch is turned to ON, while the control lever 3 ATT working equipment 3 is installed in a position other than neutral.
 

ALA-5229 *

The automatic adjustment function of the horizontal tilt angle is switched off before or after at Proposition stop.
 

 

 

ALA-5255 *

Improper management of the automatic functions adjust the horizontal angle.

1.     Moving the tilt lever in anreverse direction.

2.     Inclusion of buttons horizontal inclination, whereas the tilt control lever isXia horizontally.

3.     The inclusion of the automatic function of the horizontal tilt, while installed on the car load.

 

* The machine is equipped with an automatic adjustment function of the horizontal angle.
