Regular care of the machine must be carried out at least once per
week. This prevents malfunctions and signs of wear.
Any abnormalities detected during regular care must be reported to
the supervisor! He must immediately initiate correction or
maintenance or notify Rühle Service!

knife level) and of all grate frames:
a. For easy running and axial play!
b. For abrasion (plane surfaces)!
Replace defective rollers!
In case of abrasion, check the corresponding sliding
surface on all knife levels for damages!
Replace defective knife levels!
g) Visually check for changes or damages on all machine sides
and accessible machine parts, e.g. the knife levels. The

Cutting machine SR 1 / SR 1 Turbo
15
machine must be shut down in the event of any damages or
changes!
