SAFETY MEASURES DURING OPERATION 10.2.5 EMERGENCY LOWERING SYSTEM When the engine is in operation or not in operation, you may lower the work unit with the emergency lowering system. Ensure that nobody is standing under the work unit. Likewise you may release the rest pressure in the hydraulic circuit. Turn the lever of the emergency lowering system to position '2'. The work unit is lowered, or the rest pressure is released. Turn the lever of the emergency lowering system back to posi- tion '1'. 10.2.6 WORKING CLOSE TO OVERHEAD POW- ER TRANSMISSION LINES A voltage overspill may occur, if you or the machine get too close to overhead power transmission lines.
For this reason, always heed the required safety distance between the ma- chine and the overhead power transmission lines. Before you start work, obtain information about line voltages from your supply company. When estimating the distance, take into account all possible movements of the machine, the work unit, and the line. An un- even surface may result in the machine swaying, or wind may move the lines, etc.. 30 2 1 75 154 _ Voltage Min.
