WARNING
WARNING
The electronic weighing equipment you have purchased has been manufactured using high quality components and
the latest production techniques to ensure reliable, trouble-free operation for years to come. To obtain the best
possible performance from your weighing equipment, please read this manual carefully.
The load bar consists of a steel tube containing load cell mounts,
two factory calibrated load cells. The load bars are of solid construction and, therefore, do not require any
horizontal checking (check rods). Load bars are designed to withstand horizontal loads in the same range as their
capacity without any damage. Care should be taken to remove the possibility of horizontal impacts with the scale
platform. Impacts or collisions tend to create very high forces.
The versatility of the load bars allows any platform or container
beneath them. Various indicator combinations can be matched to the load bars to meet specialized applications.

The following points are to help ensure proper installation of the load bars. If any further assistance is required,
please contact your nearest factory or dealer.

• Try to install the load bars on a firm, level surface. The load bars do not have to be installed perfectly
level, but a substantial slope will decrease accuracy. All weight transfer must take place through the
pads at the end of each load bar. Make sure there is no contact between the ground and the center of the
load bar.
• Install the load bars in the upright position. This will allow for accurate weighing and will help keep
foreign material out of the load bar.
