Wiring
Always check the direction of rotation of the motor
prior to mounting. Rotation of the Multicutter rotor
is anti-clockwise viewed from the motor side.
If the Multicutter rotor rotates in the opposite
direction, the knives cutting edge will be damage
immediately. Do not rotate the rotor manually in
the opposite direction as even a few rotations in
wrong direction may damage the knives.
Maintenance
Always stop the Multicutter during repair and
maintenance, and make sure that it cannot be started
by mistake, while the repair and maintenance is carried
out. Always take care to switch off and lock the safety
switch (Isolator) during repair and maintenance.
Greasing
All the bearings of the Multicutter have been lubricated
for life and require no further greasing.
Motor
See the maintenance instruction from the motor
producer.
Knives
Note: For a new Multicutter, it is recommended to
check the adjustment of bottom knives after the first
1-2 hours of operation, also if new knives have been
mounted. The check is especially important when thin
materials are cut.
Then check regularly that the cutting efficiency of the
Multicutter is satisfactory. The necessity to adjust/
sharpen the knives will depend on conditions of use.
Check that the local power supply meets the
specification for the electrical equipment.
All electrical installations must be carried out according
to the current local legislation.
Take care to mount a lockable safety switch (Isolator)
for the Multicutter to ensure that it cannot be started by
accident – e.g. during repair and maintenance.
The unit may not be automatically restarted after a
power failure.
Grind /replace the knives when it is not longer possible
to adjust the Multicutter to have satisfactory cutting
efficiency.
Grinding of Rotor Knives
It is recommended to keep the original package of the
Multicutter in the event that it is necessary to have
it serviced. In order to pack the Multicutter into its
package, disassemble the motor. It is recommended
to uninstall the safety switch at the same time to avoid
dismounting electric wires.
The rotor is ground in a special grinding unit to obtain
appropriate cutting surface of the knives and exact
centering of the rotor axis. See: separate grinding
instructions for the Multicutter.
To avoid longer periods of downtime, Kongskilde can
supply newly ground replacement rotors.
Kongskilde recommends the replacement of the
Multicutter bearings at the same time as grinding of
the rotor. Only original bearings for the Multicutter must
be used (see: list of spare parts). The bearings used
in the Multicutters are special precision bearings. The
use of standard bearings may reduce cutting efficiency
of the Multicutter.
