Page 9: Safety Instructions
Safety Instructions SAFETY INSTRUCTIONS General Safety Instructions Before using the machine, always check both it and the tractor for roadworthi- ness and operational safety! As well as the notes in these instructions the operator is advised to comply with the generally applicable safety at work regulations and those relating to use of the public highway! ... - Page 10 Safety Instructions The release ropes for quick coupler latches should hang freely and in the low- ered position must not release the quick coupling by themselves. Never leave the driver's seat whilst in motion! Handling behaviour, steerability and braking are influenced by mounted imple- ments, trailers and ballast weights.
- Page 11 Regularly check the hydraulic pipes and replace them in the event of damage or signs of ageing. The replacement pipes must comply with the technical specification as laid down by Lemken! When searching for leaks appropriate aids should be used because of the dan- ger of injury! ...
- Page 12 Safety Instructions Repairwork on tyres may only be conducted by trained staff and with suitable tools! Check air pressure regularly and adhere to the advised air pressure! Maintenance Repair-, maintenance- and cleaning operations as well as adjustments and remedy of function faults should principally be conducted with engine stopped and brakes applied.
