PRECAUTIONS FOR MAINTENANCE 2.8 PRECAUTIONS FOR MAINTENANCE 2.8.1 WARNING PLATES Before starting any maintenance operation, position the ma- chine on a firm and level surface, rest the equipment onto the ground, engage the safety locks of either the equipment and the controls and stop the engine. If another person starts the engine and operates the control le- vers while the operator is providing for service, this may result in serious injuries or even death.
To avoid these risks, always attach warning plates to the control levers and to the ignition key before performing any mainte- nance operation; if necessary, attach additional warning tags al- so around the machine and in particular on the cab door handles.
