GENERALITIES:

Read the Operator’s manual carefully before starting, operating, maintaining, fuelling or servicing the machine. Carefully read the explanation to each and all safety signs in the special section of this Manual before starting, operating, maintaining, fuelling or servicing the machine. Machine-mounted safety decals are colour coded yellow with black borders when they refer to points where special ATTENTION must be paid and failure to observe them may cause a serious DANGER to the integrity of machine operators.

• It is fundamental that all machine operators know very well the meaning of each safety plate as this considerably decreases operating hazards and accidents. Do not allow unauthorised personnel to operate or service this machine. Do not wear rings, wrist watches, jewellery, loose or hanging garments, such as ties, torn clothing, scarves, unbuttoned or unzipped jackets that can get caught in moving parts.
• Wear certified safety clothes such as: hard hat, no-slip footwear, heavy gloves, ear protection, safety glasses, reflector vests, respirators every time the job requires it. Ask your employer about safety regulations in force and protective equipment. Always keep the operator’s compartment, step plates, grab-rails and handles clean and clear of foreign objects, oil, grease, mud or snow to minimise the danger of slipping or stumbling. Remove mud or grease from your shoes before operating the machine. Do not jump on or off the machine.
• Always keep both hands and one foot, or both feet and one hand in contact with steps and/or grab rails. Do not use controls or hoses as hand holds. Hoses and controls are movable parts and do not provide solid support. Besides, controls may be inadvertently moved and cause unexpected movement of the machine or its attachments. Never operate the machine or its attachments from any position other than sitting in the driver’s seat. Keep head, body, limbs, hands and feet inside the operator’s compartment at all times to reduce exposure to external hazards.
• Be careful of possible slippery conditions of the steps and hand rails as well as of the ground around the machine. Wear protective boots or shoes with the soles made of highly no-slip rubber Do not leave the machine until it has come to a complete stop. Always check height, width and weight limitations which may be encountered in the working site and ensure the machine does not exceed them. Assess exact paths of gas ducts, water mains, telephone lines, sewers, overhead and underground electric lines and all other possible obstacles.
• Such paths should be opportunely defined by competent Authorities. If necessary, require that the service is interrupted or said installations are moved prior to starting the work. Define the rear upperstructure swing area and provide for opportune barriers to prevent access into it. Never exceed machine lifting capacity. Remain within the limits shown in the loading capacity chart which located on the machine.

STARTING:

• Never start or operate a failed machine. Walk all around the machine before mounting. Before operating the machine, make sure that any possible dangerous condition has been properly removed. Before starting machine, always check that all controls are in the neutral position and the safety lever is in the LOCK position.
• Immediately report any malfunction of parts or systems to the maintenance managers for proper action. Prior to starting the engine, check, adjust and lock the driver’s seat for maximum riding comfort and control accessibility.
• Prior to operating the machine and/or its attachments, check that bystanders are outside the machine operating range. Sound the horn. Obey all hand signals, safety indications and signs. Due to the presence of flammable fluids, never check fuel level, refuel, charge the batteries in the presence of smoking materials, open flames or sparks. Adjust all rear-view mirrors for maximum visibility of the area behind the machine. Ensure that engine speed is appropriate to the job to be carried out.
