In addition, also read and note the following: "Technical information from cardan shaft manufacturer"
Impairment of communication and discomfort due to oscillating cardan shafts!
If cardan shafts are connected or aligned incorrectly, this can result in noise generation and vibration
hazards.
• Always follow the instructions of the cardan shaft manufacturer.
• Observe permissible flex angle and minimum profile overlapping of the cardan shafts.
Risk of crushing when assembling/disassembling stiff cardan shaft couplings!
Cardan shaft couplings may become stiff due to installation errors.
• Wear protective gloves.
• Before installation, check that the PTO shaft is in perfect condition and make sure that the
components to be installed are clean.
Risk of catching hands or work clothing in the rotating shaft end (without cardan shaft)!
There is a risk of injury due to accidental contact with the exposed rotating shaft end.
Before start-up/operation, make sure that a suitable PTO shaft guard is installed. If no suitable PTO shaft
guard is present, please request one from us.
