SAFETY RECOMMENDATIONS
Before usin the crane scale, please, read this manual carefully and follow the instructions.
DON´T overload the crane scale, this could seriously dama e the loadcell (repair not covered
by the warranty)
DON´T leave any wei ht on the hook for a lon time, this reduces the accuracy of the
equipment and shorts the life of the loadcell
Before usin the crane, check the superior and inferior hook rin .
Replace the batteries when the display shows the low power indicator.
DON´T use the crane in rain or storms.
DON´T try to repair the crane. Please, contact with your Distributor.

USE OF CRANE SCALE
Turn on
Press the key for 1 second to turn on and restart the crane.
Turn off
Press the key for 1 second to turn-off the crane.
The display will show the messa e “OFF”
TARE
Press the key to subtract the wei ht of a container.
The messa e “TARE” will appear on the display and the
screen will remain at zero.

If the wei ht exceeds the 100%F.S., or if it is less than 0, no
Tare may be made.
If the readin is not stable, no Tare may be made.
Tare function reduces the ran e of capacity of crane scale.
Example: If Tare is made with a container of 10 k and the maximum
capacity is 50 k , the available capacity will be of 40.18 k (5000 -1000 + 9
additional divisions)
To clean tare, press a ain the key
The messa e “TARE” will disappear and the ross wei ht
will activate.
2

Hold Function
Press the HOLD / U key to hold the data shown on the display
(value frozen on the display)
The messa e “HOLD” will appear and the wei ht
will remain frozen on the display.
Press a ain the HOLD / U key to deactivate the Hold function.
The messa e “HOLD” will disappear and the crane will return to normal
wei hin mode.
Wei ht Units
Press the HOLD / U key for 1 second to select the desired wei ht unit
(k , lb y N)
The unit cannot be chan ed if a tare has been made.
3

Reset to zero
Press the key for 1 second to reset the display to zero.
The messa e “ZERO” will appear on the display and the
display will remain at zero.
The reset-to-zero function cannot be made if the readin is not stable or a
tare has been made.
The reset-to-zero function cannot be made if the wei ht value is above the
manual zero ran e.
Settin
To access to the settin mode, press at the same time the
and HOLD / U keys for 1 second.
