Page 27: Adjustments
ADJUSTMENTS OUTER SWATH WHEEL The angular position of the swath wheel compared to the cutterbar can be adapted to working conditions enabling a regular flow of the cut crop towards the rear. Position the swath wheel so that maxi- mum angle (A') (fig. A) is obtained. In difficult working conditions (long, dense, bent over crops) position it towards mini- mum angle (A) (fig. - Page 28 SAFETY BREAK-AWAY A breakaway latch allows the cutterbar to swing back if an obstruction is hit (photo 33). IF THE LATCH RELEASES, STOP THE TRACTOR IMMEDIATELY AND DISENGAGE THE PTO. To reset the cutterbar, back the mower until the cutterbar is in its normal position. The factory setting of the latch is adapted to most working conditions.

FOR THE CORRECT OPERATION OF YOUR MACHINE, ALWAYS USE GENUINE KUHN SPARE PARTS. - 29 -...
- Page 32 2. KNIFE REPLACEMENT To replace knives, first clean the area around nut (A) (photo 37) and remove nut with the box spanner (T) supplied with the machine. To facilitate the removal of the nut, we recommend to place a block of wood (Z) between 2 discs to stop them from rotating (photo 37).
- Page 33 Dull knives require more horse power to cut the crop and will leave an uneven stubble. Worn knives should either be turned over on the same disc to use the other cutting edge, or replaced. When turning or replacing the knifes, make sure there is a 1 mm minimum gap between the knives or their mount- ing bolts and the cutterbar wear plates.
- Page 34 Make sure cone lids (J) are properly secured in place (photos 43 and 44). Replace immediately a loosen or damaged cone lid. REGULARLY CHECK ALL NUTS AND BOLTS FOR CORRECT TIGHTNESS, PARTICULARLY THOSE SECURING THE DISCS AND KNIVES. 4. BELTS Belts must be properly tensioned at all times to avoid excessive flopping and slipping.

Page 36: Lubrication
LUBRICATION It is forbidden to discard oil, grease or filters of any type. These must be given to specialised waste disposal organisations to protect the environment. IMPORTANT Imperatively change oil in : - cutterbar bevel gearbox - cutterbar after the first 10 hours of use [SAE 80 W EP (GL4)]. Thereafter, oil must be changed every 200 hours of work and at least once per year. - Page 37 2. CUTTERBAR Note : Make sure the cutterbar is in the vertical position when checking, adding or changing oil. The oil level is at its maximum when oil flows out of the filler plug hole. Check oil level once a day. Add SAE 80 W EP (GL4) oil to the cutterbar at filler plug (D) (photo 48).
