1. Check the tyre air pressure. It should be 60 kPa (0,6 kp/cm2). 2. Dismantle the front hood and right-hand fender as described on page 20-21. 3. Vertical adjustment of the cutting unit is made with the adjusting nuts on the back edge of the lift-strut. 4. Raise the cutting unit at the front edge by shortening the lift-strut. Lower the cutting unit at the front edge by lengthening the lift-strut. 5. Tighten the nuts against each other after the adjustment. 6. On completion of the adjustment the unit�s parallelism should be re-checked. Fit the right-hand fender and the front hood.
