    - using only genuine spare parts, equipment and accessories as designated by the manufacturer. The EL 142 must only be operated, maintained and repaired by competent persons who are familiar with machine specifications and operations and are aware of any danger involved.
  • Page 5 GENERAL SAFETY RECOMMENDATIONS Before operating the machine, always ensure that tractor and machine are in accordance with work safety and road traffic regulations. BASIC PRINCIPLES 1. In addition to the recommendations given in this manual, legislation on work safety and accident prevention must also be respected.
  • Page 6 17. Drive speed must be adapted to ground conditions as well as roads and paths. Always avoid abrupt changes of direction. 18. Precision steering, tractor adherence, road holding and efficient braking are influenced by the type of implement, weight, ballast of front axle, ground or road conditions. It is therefore of utmost importance to be cautious in every given situation.
