CARE AND MAINTENANCE
1. For weighing operaon, don't load the scale with weight load exceeding the maximum capacity.
2. Perform roune inspecon and maintenance to ensure operaon safety for these basic items:
a) Check for loose bolts.
b) Check hook and shackle for deformaon, wearing and tearing.
c) Check other scale component for signs of metal fague.
d) Check for missing hook latch.
3. Do not touch the display screen directly.
4. Do not use the scale in the rain or in a polluted environment.
5. Remove the baery and store the scale in a dry place if the scale is not going to be used for some me.
The scale uses maintenance-free 6V/4.5AH Lead-Acid baery. When scale is with low power, it will display the
following signals:
a. When the low power indicator light is on. The scale needs to be charged now. However, the scale can connue to be
operated for about 3 hours without charging.
b. Aer the low power indicator is ON for several hours without charging or there is no more power in the baery, the
crane scale will be powered off automacally. It will take about 5 hours to fully charge the baery.
C. Aer baery charging, if there is no display, it indicates that either there is difficulty in baery charging or a
damaged baery.
With a fully charged baery, the scale can be operated for about 30 hours. To prolong the baery life, recharge the
baery promptly for every 20 hours of usage. When charging the baery, use the original charger supplied with the scale
to prevent the baery from unnecessary damages. In addion, turn off the power to shorten the recharging me. WHEN
recharging the baery, the recharging light will be red. When the light is green, it indicates the baery is charged fully.
