effects to health. Because an indication according to the danger order
is not necessary, therefore in principle please pay attention to:
Avoid skin contact
Avoid skin contact with these oil and lubricants. Protect your skin by
skin protection creams or oil-resistant gloves. Skin contact can lead to
skin diseases.
Do not use oil for cleaning
Never use oil and lubricants for hand cleaning! Chips and waste in this
oil and lubricants can extra lead to injuries.
Change dirty clothing
Change extremely filthy oiled clothing as soon as possible. Oil can
cause health injuries.

The length of the pto drive shaft has to be adapted. This depends on
the distance between tractor and machine.
Correct length
To long a pto drive shaft may seriously damage drive bearings of both
tractor and machine. Which is beyond any warranty.
Prior to coupling the pto drive shaft check the length:
> Correctly line-up tractor and machine
> Ensure the tractor pto is clean and greased
> Fit both pto drive shaft halves (not connected!)
> Hold both pto drive shaft halves together, ensure
• the protection tube shall be at least 5 cm shorter
• the overlap of the profiled drive tubes shall be at least 37 cm
Shortening the pto
drive shaft
A = B
> Exactly determine the correct length of the shaft
> Shorten the protection tubes
> Shorten the profiled drive tubes
The length of both cut-off ends shall be identical.
> Clean cut ends of both protection tubes and profile tubes to ensure
they are all smooth and clean
