the cab floor when shifted;

d) the lever 1 cannot be clearly fixed
in its extreme positions.
Readjustment is performed as follows:

2. Remove the PTO guard.
3. Unscrew the bolt (16), remove the lock bar
(17) from the eccentric axle shank (15)

cannot be rotated by hand).
4. Fix the axle with the lock bar (17) and bolt
(16).
5. Install the PTO guard to place.
