9 Transportation & Storage 9.1 Testing upon acceptance When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage. 9.2 Packaging / return transport Keep all parts of the original packaging for a possibly required return. Only use original packaging for returning. Prior to dispatch disconnect all cables and remove loose/mobile parts. Reattach possibly supplied transport securing devices.
10 Unpacking, Setup and Commissioning 10.1 Place of installation / place of operation The balances are designed in a way that reliable weighing results are achieved in common conditions of use. You will work accurately and fast, if you select the right location for your balance.
10.4 Installing the chair scales In delivery state the balance is adjusted in a manner that when placed on an even surface the air bubble of the water balance is in the prescribed circle. To check place scales on an even surface. Check if the air bubble of the level is within the prescribed circle. If the air bubble in the level is not within the prescribed circle, the wheel height has to be adjusted, see chap. 9.4.1. Check levelling regularly.
10.4.1 Levelliing • The wheel height has to be adjusted for levelling. Levelling is restricted to specialist staff possessing well acquainted • with the workings of weighing scales. Place scales on an even surface. Arrest the brake Turn the wheel (1) clockwise until the air bubble of the water balance is in the prescribed circle Screw counternut (2) upwards till to the stop and it with a suitable tool (e.g. pliers).
