Turtle symbol:
It is normally turned off; when it is dis-
played, it indicates the activation of the electric pallet
truck's "soft" mode, in which the maximum speed and
acceleration are reduced.
Wrench symbol (only for EHW 15 and
EHW 20):
It is normally off, when the icon appears it indicates the
request for scheduled maintenance or the alarm condi-
tion. In this case, the corresponding code is displayed.
The information provided can be very useful. Malfuncti-
ons can be quickly identified by the operator or service
technician, allowing the problem to be solved quickly.
Hourglass symbol (only for EHW 15 and EHW 20):
It flashes when the hour counter is in operation.
Battery indicator:
EHW 12:
The charge status of the
battery is indicated by
four LEDs on the tiller:
The first green LED from the left lights up and indicates
75% -100% of the battery charge.
The second blue LED from the left is on and indicates
50% -75% of the battery charge.
The third yellow LED from the left is on and indicates
25% -50% of the battery charge.
The fourth LED from the left is lit and indicates 0% -25%
of the battery charge.
If there is an error, four LEDs flash for 1s, then the first
green LED from the left flashes and is counted, then the
fourth LED from the left flashes and is counted. The
quantity that the green LED blinks times ten times, then
plus the quantity that the LED blinks means the error
code.
EHW 15 and EHW 20:
