2 - Safety Notes37Universal Joint ShaftA rotating shaft can catch clothes, tools or aids, if touching or getting in contact with each other. Risk of severe damages andinjuries as the rotating shaft is driven by a powerful torque from the tractor.Use only the power take-off (PTO) shaft prescribed by HARDI, equippedwith the proper safety devices.Read and follow the delivered instruction manual from themanufacturer of the PTO shaft.The protective pipe and PTO shaft guard must be undamaged, and theshield of the tractor and sprayer universal joint shaft must be attachedand be in proper working condition.Safety devices must be in good condition when your are working with the sprayer.You may install or remove the PTO shaft only after you have done all of the following:• Switched off the universal joint shaft drive• Switched off the tractor engine• Removed the ignition key• Applied the parking brake.A lways ensure that the PTO shaft is installed and secured correctly both at the tractor end and at the sprayer pump end.When using wide-angle PTO shafts, always install the wide angle joint at the pivot point between the tractor and sprayer.Secure the PTO shaft guard by attaching the chain(s) to prevent movement.Observe the prescribed pipe overlaps in transport and operational positions. See the operating manual from the PTO shaftmanufacturer.When turning corners, observe the permitted bending and displacement of the PTO shaft.Before switching on the universal joint shaft, check that the selected universal joint shaft speed (rpm) of the tractor matchesthe permitted drive speed of the sprayer.Stay below the maximum speed (rpm) suitable for the PTO shaft.Instruct people to leave the danger area of the sprayer, before you switch on the universal joint shaft.While work is being carried out on the universal joint shaft, there must be no one in the area of the universal joint shaft orPTO shaft, while it is rotating.When the tractor engine is turned off, the universal joint shaft must also be switched off. This prevents an unintentionalrestart of the universal joint shaft immediately, when the tractor engine is turned on again.Always switch off the universal joint shaft if it is not needed in action, or if excessive bending of the PTO shaft occurs.You may work on the sprayer only after all moving sprayer parts have come to a complete stop.Secure the tractor and sprayer against unintentional starting and unintentional rolling, before you perform any cleaning,service or maintenance work on universal joint shaft-driven sprayers or PTO shafts.After decoupling the PTO shaft, place it on the holder provided.After removing the PTO shaft, attach the protective sleeve to the universal joint shaft stub.If using a travel-dependent universal joint shaft, note that the PTO speed depends on the drive speed of the vehicle, and thatthe direction of rotation reverses, when you drive in reverse.
