SPECIAL SAFETY RECOMMENDATIONS 1. Stay a safe distance away from the mower when discs are rotating. 2. Crushing and shearing zones which could cause serious bodily injury when changing the machine from transport to work position and vice versa may exist. To prevent possible injury, be extra careful when maneuvering and ensure that everyone is at a safe distance away from the machine.
SAFETY DECALS THE FOLLOWING SAFETY PICTORIALS HAVE BEEN PLACED ON YOUR MACHINE IN THE AREAS INDICATED. THEY ARE INTENDED FOR YOUR PERSONAL SAFETY AND FOR THE SAFETY OF THE PEOPLE WORKING WITH YOU. THE TEXT SHOWN ON THEM GIVES THEIR PRECISE MEANING.
LOWERING THE CUTTERBAR AND ADJUSTMENTS FOR WORK 1. Lowering the cutterbar To lower the cutterbar from the transport position to the working position, first fit linchpin (D) into hole (H) and pull cord (X) to release latch (G). Then manually lower bar and remove knive guard.
4. Lifting mechanism adjustment The mower can be raised by the tractor 3-point linkage. As the mower is raised, the cutterbar is automatically locked in the horizontal position. Adjustment to secure this horizontal position is made by set screw (V) which should always be secured by lock nut (E).
6. Belt tension adjustment First loosen the 4 screws (Y) which secure the pulley housing then loosen jam nut (T). Tighten belts using bolt (Z) until tension is sufficient to prevent belts from slipping during operation. Do not overtighten belts as they also act as a safety device and should slip in case the machine becomes blocked.

ALWAYS DISCONNECT THE PTO SHAFT FROM THE TRACTOR PTO WHEN PUTTING THE MACHINE INTO THE TRANSPORT POSITION. When parking the machine, secure the triangular stand (B) on the left-hand side into the lower position with handle (V) as shown in the photo opposite. The mower can than be lowered on the tractor hydraulics where it can stand level while uncoupling from the tractor.
- Every 3 hours of use the knife head ball joint. For protection against rust, use SHELL ENSIS 30 oil. To obtain maximum durability from KUHN machines, we recommend the use of SHELL LUBRICANTS. GENERAL MAINTENANCE - Regularly check tightness of nuts and bolts.
CUTTERBAR MAINTENANCE AND ADJUSTMENT A well guided knife and sharp sections are essential for a good cut. A blunt knife requires more power. It is preferable that the sections be sharpened using a blade sharpener though it is possible to use abrasive disc grinders. Wearing parts like knife guides, knife clips, wear plates or knife heads are made of heat treated steel and are very resistant to wear.

3) KNIFE CLIPS (3) must be correctly fitted over the top of the raised section. Ensure they are not set at the back or at the front only, for that would increase the wear. Screw (V) can be adjusted to lower the knife clip and give good support to the knife on the surface of the finger (1).
2) HYDRAULIC CUTTERBAR LIFT (No. 100 60 50) The FA 392 can be fitted with an optional hydraulic cylinder to raise and lower the cutterbar. The hydraulic cylinder assembly (N) is fitted in place of the manual lifting rod and the hydraulic hose is connected to the tractor single acting outlet.
