Clean the mechanical parts (see picture 2) with compressed air from dirt and metal
chips.
If the upper sealing lips of the protection boot are damaged too seriously, the boot must
be changed against a new one.
13.2.2 General inspections
The mechanical transmission elements of the cutter unit are subjected to very high
mechanical stressing and must, therefore, be inspected at certain intervals. This helps
to detect wear early so that fractures of these wearing parts can be prevented by
replacing them in time.
Parts in perfect condition can be fi tted again after careful application of LUKAS special
grease for cutter units.
Parts with insignifi cant wear (fretting marks) can be repaired by polishing and fi tted
again after greasing.
More pronounced wear marks require replacement of the damaged parts (by pairs).
At these intervals, crack testing of the cutter blades is equally mandatory. For this
purpose, a special crack test kit is available.
To protect the device against external corrosion clean its surface from time to time and
slightly grease it with oil.
13.2.3 Function and load test
If there is any doubt as to the safety and reliability of the equpiment, carry out an
additional function and load test. For this purpose, LUKAS offers a test kit as appropriate
equipment.
