WARNING!
The two rollers must always be at the same height.
Next, adjust the protective side skids; see Section 6.2.1. The roller may also feature a scraper, namely a device
designed to clean the roller that, in turn, must be positioned correctly with respect to the roller. To adjust the position of
the roller scraper, loosen the screws (11 and 12) and lower the scraper so that it is within 2-5 mm of the roller, making
sure there is nothing to stop the roller turning freely. To finish the job, tighten the screws (11 and 12). This adjustment
should also be made after a few hours of operation.
DANGER!
The side skids must always be adjusted so that they are at least 20 mm lower than the flails
maximum working range because of the danger of objects being flung out from the sides. Flails are adjusted
correctly when they are approx. 20 or 30 mm off the ground.
