ALS-ELECTRONICS ALS-ELECTRONICS Always read this section before installing and operating the ALS- Electronics as safe as possible. STRUCTURE AND FUNCTIONING PRINCIPLE OF THE ALS-ELECTRONICS The ALS-Electronics uses the hydraulic shock-absorbing effect of the pressure accumulator (integrated into the circuit at the pis- ton head end of the lifting cylinder) to absorb vibrations during driving. This procedure permits quiet driving with higher speed. The ALS-Electronics consists of the ALS-Electronics switch, the pressure accumulator and the solenoid valve.
If the ALS-Elec- tronics switch is switched on, the solenoid valve is being opened and the circuit at the piston head end of the lifting cylinder is connected to the pressure accumulator. PRECAUTIONARY MEASURES FOR SWITCHING ON THE ALS-ELECTRONICS If the ALS system is switched on during a journey, or when the working attachment is in raised position, it may move up or down depending upon the bucket load. For this reason, extreme caution is advised when operat- ing the switch. When inspecting and servicing the machine, also lower the work equipment to the ground then turn the ALS-Electronics switch OFF before beginning to service.
The ALS system is activated when the transmission is shifted into 2nd gear and the machine is traveling at a speed higher than 5 km/h. 9-2
