The parking brake on the vehicle must be locked before work on the crane is started. Consideration must be taken to the crane's power limitations in order to handle the load safely. The data sheet states the maximal load that the crane can work with at a specific reach and with the crane tip level with the main boom’s rear bearing. The maximum load also presupposes that the vehicle is standing on flat ground. It is not permitted to exceed the maximum permitted load and reach while loading. Note that the data sheet states the maximum load without tools. Should the crane’s capacity be misjudged or exceeded, the main boom or any other function that is restrictive will drop or in some other way move uncontrollably. The load must be quickly moved to within the right working area using the outer or telescopic booms in order to stop this movement. Should the vehicle lean during loading a slewing torque is transferred to the slewing motor’s gearing. If the slewing motor’s maximum slewing torque is exceeded, the crane boom will slew out uncontrollably. In the event of this happening the load should be lowered to ground level in the quickest possible way.
