Any abnormalities detected during regular care must be reported to
the supervisor! He must immediately initiate correction or mainte-
nance or notify Rühle Service!
Care schedule:
a) Disassemble the machine according to the cleaning instruc-
tions. Check for any parts moving with difficulty, material
abrasion or other signs of wear and tear.
b) Remove the cut-off knives with the knife sharpener and
check them for any damage or broken blades.
c) Sharpen the grate knives in the knife levels with the knife
sharpener and check them for any damage or broken blades.
Grate knives must be resharpened at least every 50 work-
ing hours on a slip-resistant underlay using only little
pressure and a Rühle knife sharpener!
d) Check the slider (funnel closure) and its guide pins for dam-
ages and abrasion; remove sharp edges!
e) Check the guide rails of the slider (funnel closure) in the ma-
chine and the grate frame; remove sharp edges!
f) Check the rollers of the eccentric shafts (drive shaft for the
knife level) and of all grate frames:
a. For easy running and axial play!
b. For abrasion (plane surfaces)!
Replace defective rollers!

Cutting Centre SR 2 Turbo
15
In case of abrasion, check the corresponding sliding sur-
face on all knife levels for damages!
Replace defective knife levels!

and accessible machine parts, e.g. the knife levels. The ma-
chine must be shut down in the event of any damages or
changes!
5.2 Regular maintenance
Regular maintenance of the machine must be carried out every 2000
hours of operation but at least once per year.
