Maintenance :
Keep your machine maintained in good condition. Things like
excessively worn bushings, pivot pins and slideways, as well as lack of
lubrication to these areas can have an adverse effect on weighing accuracy.
NOTE: After any major servicing particularly if you have replaced worn components
or carried out welding repairs, you should re-calibrate the weighing system. If
the hydraulic system has been drained and re-filled you should also check for
any air which may have become trapped at the pressure sensor.

Lifting procedure
The correct lifting procedure is especially important for dynamic weighing.
The load should be lifted smoothly and consistently through the weighing
position. The best procedure is as follows :
1.
Having picked up the load, crowd (roll) the bucket right back as far as it will
go.
2.
Pull the lift lever right back with the engine at idle.
3.
Increase engine revs to the "weighing speed" and lift smoothly without
bouncing or jerking. Ensure that you lift at the weighing speed as you pass
through the reference position (dynamic weighing).
If when lifting the bucket in dynamic weighing mode, the instrument
displays ‘FASt’ or ‘Slo’ and beeps 3 times, then lower and lift again at an
appropriate speed.
This also applies when checking the zero weight (section 3.3, 3.4).
