The load must be lifted freely without touching the housing of the indicator or other objects.

When operated on a non-even, sloped surface the accuracy of the scale is reduced by 0.1% for every 2° of
inclination. This effect is also caused by holes in the floor. For best weighing results use scale on flat and
even level surface.
The best weighing result is obtained when the center of gravity of the load lies between the forks. Excentric
load may lead to bending and twisting of the forks, and can result in greater inaccuracy.
Units subject to Weights & Measures approval are equipped with an incline sensor that disables the display
when the inclination exceeds the permissible limit.

Temperature range: Within the range from
–10 to +40°C the max. weight deviation is 0.1% of the measured
load. Outside this range deviations of up 0.3% may occur.
In order to prevent condensing of humidity in the electronics, rapid changes of temperature should be
avoided. If substantial differences in ambient temperature are experienced, the scale should be switched off
to give it time to acclimatize to the new environment.
1.1.3
Maintenance
The calibration of every scale must be checked at regular intervals. RAVAS recommends maintenance of the
weighing system once a year. Scales subject to Weights & Measures approval must be verified with certified
test weights every year by a certified organization.
The same rules that apply to a simple pallet truck also apply to the chassis of your mobile scale, i.e. based on
experience, the scale will continue to operate even if the chassis is already damaged due to excessive
overload.
In general:
Pulling the pallet truck instead of pushing it makes moving the load easier because of the steering
wheels on the side of the draw bar.
When the lifting mechanism is not in use, the hand lever should be in middle position. This
provides for a longer lifetime of the gaskets.
Only clean the indicator with a soft clean cloth that has been dampened with a mild window type
cleaner. Do not use any type of industrial solvent, do not spray cleaner directly on the unit, do not
use water jets or the unit may be damaged.
To prevent damages to the weighing system make sure that any welding work on the unit is solely
carried out by RAVAS Service.
The bearings of the wheels (except for Vulkollan) as well as the joints at the rollers should be
cleaned and lubricated at regular intervals.
Check oil level at 6-month intervals.
