10.8 Cutting knives of mixing auger(s)
Grind the cutting knives of the mixing auger if necessary.
Blunt cutting knives require a higher power of the mixing
auger(s) thus also increasing the machine’s fuel consumption..
Daily check the cutting knives from the service platform / the
ladder for visible defects. Replace damaged or worn cutting
knives in good time.
10.8.1 Grind cutting knives
WARNING
Risk to eyes due to blown-away abrasive particles when grinding
the cutting knives!
Always wear protective goggles when grinding cutting knives.
Use a right-angle grinder with a flap grinding wheel (Fig. 249)
when grinding the cutting knives.
Only grind the cutting knives on their smooth side, never on their
corrugated side.
Carefully regrind the cutting knives such that they do not heat up
much. If the cutting knives change colour during grinding:
they have heated up excessively,
this will reduce the service life of the cutting knives.
1. For grinding the cutting knives, enter the
empty mixing container through a discharge
opening. Absolutely observe the information
in the chapter "Enter the mixing container",
from page 121.
2. Wear protective goggles and protective
gloves.
3. Carefully grind the cutting knives on their
smooth side.
4. Remove any foreign objects (tools etc.)
from the mixing container. Clean the mixing
container from grinding residues if
necessary.
5. After completing work, leave the mixing
container through the discharge opening.
