PRECAUTIONS FOR MAINTENANCE 2.8 PRECAUTIONS FOR MAINTENANCE 2.8.1 WARNING PLATES Before starting any maintenance operation, position the ma- chine on firm and level ground, engage the safety locks of the equipment and of the controls, stop the engine and apply the parking brake. If another person starts the engine and operates the controls while the operator is providing for service, this may result in serious injuries or even death.

DO NOT START ENGINE To avoid these risks, always attach warning plates to the steer- ing wheel, to the control levers and to the ignition key before performing any maintenance operation; if necessary, attach additional warning tags also around the machine and in partic- ular on the cab door handles. RWA01210 2.8.2 TOOLS Use only the tools provided with the machine and high-quality tools suitable for the tasks to be performed. Do not use worn, damaged, low-quality tools or tools that are not suitable for the tasks to be performed, in order to avoid any personal injuryti. After use, carefully clean the tools and put them in the com- partment obtained inside the seat support.

If the operator plans to keep on the machine some tools whose dimensions exceed those of the compartment positioned under the seat, he can store them in an appropriate tool box positioned on the rear outer part of the cab. See “3.5.10 ADDITIONAL TOOL BOX (if provided).” RWA01310 RWA02860 2.8.3 PERSONNEL Only authorized and duly trained personnel can service and repair the machine; additional precautions must be taken when grinding, welding and using a sledge hammer or heavy hammers. When assemblying the equipment or cylinder connection pins, use wooden, plastic or in any case not exces- sively hard tools to check the centering of the holes.

Do not use your fingers, since you run the risk of cutting them. 44
