Safety Information Working safely with the machine
noted. – Working procedures when using machines with grabs require the machine operator to receive special instruction and training. – Use as part of the work process is only permitted when the machine operator has sufficient training and practical experience.
1.10.2
Safe use of machines with tower elevation – Due to the tower elevation, the centre of gravity of the machine will be displaced upwards in the vertical direction. The driving and work characteristics of the machine will thus be influenced persistently, e.g. through reduction of the dynamic stability. – Due to the heightened centre of gravity, the machine must be aligned horizontally before use. In horizontal alignment, the centre of gravity of the upper structure is over the centre of the chassis, which reduces the risk of tilting. – The machine can still sway and tilt despite being aligned! The following instructions are therefore to be observed at all times: When moving the machine: • Rotate the upper structure parallel to the undercarriage chassis (transport position). • Draw the equipment as close as possible to the machine. • Only at this point may the support feet be retracted and the machine moved. • Moving with loads is not permitted. • Check the terrain to be covered to ensure that the ground is solid and even. Potholes and uneven surfaces jeopardize the stability of the machine. • Adjust vehicle handling to suit the altered machine characteristics (high centre of gravity) and environmental conditions. • Reduce your speed to prevent the need for sudden braking and steering manoeuvres. • Avoid sudden speed changes, such as braking, accelerating and changing direction. • Ascending gradients and obstacles may only be approached in the longitudinal direction in order to prevent unacceptable banking of the machine. • Special care should be taken when driving through narrow passages - drive slowly! When loading and unloading: • The machine must be supported and aligned horizontally before moving (slewing) the upper structure out of the transport position. • It is imperative that you check the contact surface of the support (load carrying capacity of the substrate). A support subsiding would have disastrous consequences! • Carry out all movements with increased care. • To slew the load, move the equipment as close as possible to the machine (Caution! swinging grab)and hold the load close to the chassis and above the substrate. • Avoid braking or accelerating the equipment or upper structure abruptly. • Do not lift any loads which are heavier than those given in the load chart.
1.10.3
Additional instructions for machines with rigid driver's cab elevation – When getting in or out, position the machine on even, horizontal ground. The upper structure should be positioned with the chassis in such a way that the steps and ladders are aligned with each other. – Ensure that steps, ladders and hand-rails (grips) are in good condition. In particular, you should ensure that they are free of dirt, oil, ice and snow. NOTE: To ensure that the doors open properly in all weather conditions, the door seals must be dusted with talc or silicon at least every two months or more often if required. The door hinges and locks should be greased regularly. – Face the machine when getting in or out and always use three-point support, i.e. two hands and one foot or two feet and one hand must always be in contact with the access system at the same time.
