SAFETY RULES
– Check monitoring instruments at start-up and frequently during operations. in case the brake pressure gauge shows a pressure lower than the minimum operating pressure, stop immediately the machine .
– DO NOT CARRY RIDERS ON MACHINE – Study and familiarise with escape routes alternate to normal exit routes. – Seat belts are required by current regulations to be provided with Roll Over Protection Structures or cabs. Keep safety belts fastened around you during operation.
– For your personal protection, do not climb on or off machine while machine is in motion.
– Make sure that exposed persons in the area of operation are clear of the machine, before starting the engine and operating the equipment. Sound horn. Obey all indications provided by flags and signals.
– NEVER COAST the machine down grades and slopes with the transmission in neutral or neutralised. Choose and shift into the most appropriate gear to keep the speed required, thus preventing any loss of control.
– Do not operate machinery in a condition of extreme fatigue or illness. Be especially careful towards the end of working shift.
– Do not operate machine with brakes out of adjustment.
– Operate the machine at speeds slow enough to ensure complete control at all times.
– Travel slowly over rough terrain, on slopes or near dropoffs, in congested areas or on ice or slippery surfaces.
– When backing, always look to where the machine is to be moved. Be alert to the position of exposed personnel. DO NOT OPERATE if exposed personnel enter the immediate work area. STOP THE MACHINE.
Maintain a safe distance from other machines. Provide sufficient clearance for ground and visibility conditions. Yield right-of-way to loaded machines.
– Maintain clear vision of areas of travel or work. Keep cab windows clean and repaired. – When machines are operating in tandem, the pusher (rear) must be equipped with the appropriate deflectors to protect the unit in front from the air stream coming from the radiator.
– When pulling or towing through a cable or chain, do not start suddenly at full throttle; take-up slack carefully. Inspect carefully for flaws or troubles before using.
– Avoid kinking chains or cables. Do not pull through a kinked chain or cable to the high stresses and possibility of failure of the kinked area. Always wear heavy gloves when handling chains or cables.
