INTRODUCTION

Personal safety Carefully read this Manual before proceeding with maintenance, repairs, refuelling or other machine operations. Repairs have to be carried out only by authorized and instructed staff; specific precautions have to be taken when grinding, welding or when using mallets or heavy hammers. Not authorized persons are not allowed to repair or carry out maintenance on this machine. Do not carry out any work on the equipment without prior authorization. Ask your employer about the safety instructions in force and safety equipment.

Nobody is allowed to seat on the operator’s place during machine maintenance unless he is a qualified operator helping with the maintenance work. If it is necessary to move the equipment to carry out repairs or maintenance, do not lift or lower the equipment from any other position than the operator’s seat. Never carry out any operation on the machine when the engine is running, except when specifically indicated. Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves, etc. All repair and maintenance operations should be carried out with the greatest care and attention. Service stairs and platforms used in a workshop or in the field should be built in compliance with the safety rules in force. Any functional disorders, especially those affecting the safety of the machine, should therefore be rectified immediately.

DANGER Unexpected movement! Make sure parking brake is applied. Secure machine with wheel chocks. Failure to comply will result in death or serious injury. D0013A

Before performing any work on the machine, attach a maintenance in progress tag. This tag can be applied on the left-hand control lever, safety lever or cab door.

Equipment Wear close fitting clothing and safety equipment appropriate for the job: • Safety helmet • Safety shoes • Heavy gloves • Reflective clothing • Wet weather clothing If environment condition require it following personal safety equipment should be at hand: • Respirators (or dust proof masks) • Ear plugs or acoustic ears protections • Goggles with lateral shield or masks for eyes protection Do not wear rings, wristwatches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open jackets or shirts with open zips which could get caught into moving parts.

Engine - Radiator Never leave the engine run in closed spaces without ventilation and not able to evacuate toxic exhaust gases. Keep the exhaust manifold and tube free from combustion materials. Do not refuel with the engine running, especially if hot, as this increases fire hazard in case of fuel spillage. Never attempt to check or adjust the belts when the engine is running. Never lubricate the machine with the engine running.
