2. Read the operating instructions supplied with the drive assembly carefully.
3. Only use the universal drive shafts supplied with the machine or recommended by the manufacturer.
4. The PTO and universal drive shaft guards must be fitted and in good condition. Make sure the
universal drive shaft tubes overlap correctly, in both the working and transport position. The universal
drive shaft guards must be prevented from rotating by the special chains.
5. Before connecting or disconnecting a universal drive shaft, disengage the PTO, switch off the
engine any remove the key from the ignition. If the primary universal drive shaft is fitted with an
overload clutch or a free wheel, it is essential that they are mounted onto the PTO of the machine.
6. Always make sure that the universal drive shafts are mounted and locked correctly.
7. Pay attention not to damage the drive assembly during lifting operations.
8. Never engage the PTO with the tractor engine switched off.
9. Before engaging the PTO, make sure that the speed setting and direction of rotation comply with
the manufacturers instructions. The machine must be used at a PTO speed of no higher than 540
min
-1
. Failing to comply with this instruction may lead to serious damage.
10. Disengage the PTO whenever the universal drive shaft angle limits indicated by the manufacturer
are in danger of being exceeded. After disengaging the PTO, moving parts may continue to rotate
for a few seconds.
11. On unhitching the machine, rest the universal drive shafts on the special supports. When the
universal drive shaft has been disconnected from the tractor PTO, refit the protective cap.
Hydraulic Circuit
1. The normal working hydraulic pressure is 180 bar. Fluid from the hydraulic circuit can pierce the
skin and cause serious injury. In case of injury, seek medical advice immediately due to the high
risk of intoxication.
2. Regularly check the condition of hydraulic hoses and the good working order of all safety valves on
the body lifting rams. Worn or damaged components must be replaced immediately. When replacing
hydraulic hoses, make sure that you only use hoses with the characteristics and quality prescribed
by KUHN. When a leak has been located, take appropriate precautions to avoid accidents.
3. Before carrying out any operations on the hydraulic circuit, lower the machine, fully retract the arm
and grab ram rods, switch off the engine and circuit pressure and remove the key from the ignition.
4. Never change the order of commands or the direction of movements on the hydraulic circuit. On
fitting hydraulic motors and rams, make sure that the circuits are connected correctly according to
the manufacturers instructions.
5. In the case of an auxiliary hydraulic unit, the gear selector lever must be in neutral during silage
cutting and loading operations.
