Fig. 11 Correct positioning of the tandem knife roller for rear hitch operation
CAUTION! Do not operate the roller on stony soil because the working
elements on the roller may become cracked.
CAUTION! The knife roller shall not penetrate into the soil deeper than 2-3
cm as this can cause an excessive wear of the roller working parts. The roller
should operate on the surface of the field.
CAUTION! Folding rollers cannot work on the rear hitch without proper
preparation by interlocking the locking pin and rotating the working rollers
accordingly.

Maintenance and lubrication
•
Clean the knife roller from soil after each use and inspect the parts and assemblies.
Otherwise, there may be a problem with the folding of the machine if the rollers are
clogged with earth and there is an additional load!
•
After the first
4 hours of operation, re
-
tighten all bolts and periodically check them
for tightness.
Failure to do so will exacerbate play and backlash and result in damage
to the implement.
•
Lubricate the lubrication points on the hinge bolts daily during the machine's service
life.
•
Use thread adhesive and only genuine screws and nuts when replacing worn parts.
•
Always remember to tighten the screwed joints properly.
CAUTION! Periodic lubrication guarantees the long service life of the machine.
