Lower Horizontal Cutter
Before opening the planer’s cover (6), ensure that the power
is disconnected and that the cutter heads are not rotating.
Use protective gloves. This is especially important when
you are loosening screws that are tightly screwed, or when
you are tightening the screws (see Safety Instructions). Be
careful of the planing knives. You can easily get cut by those,
even when touching them lightly.
The lower cutter is located in the machine table on the in-
feed side of the machine. On delivery, two planing knives are
mounted in two of the cutter head’s knife slots (planing knife
300 mm HSS, ref. no. 7000-002-8300). Two additional planing
knives, or moulding knives, can be mounted in the two empty
knife slots.
After you have adjusted or replaced planing knives or moulding
knives:
Make sure that there are no tools left inside the machine.
Make sure that all screws are reliably tightened.
Make sure that the cutter heads can rotate freely before
closing the protective cover.
Do you remember the safety instructions on pp.4-5?
Adjusting the lower horizontal cutter
The planing knives in the lower horizontal cutter should be set
so that they are level with and parallel to the machine table.
- Using a 10 mm spanner (supplied), loosen the chip breaker’s
lock screws (B), which are in the track between the chip
breaker (A) and the cutter head. After this the knife can be
raised or lowered with the help of the two recessed adjusting
screws (4 mm Allen) (C) next to the cutter’s knife slot. Use
a 4 mm Allen key (supplied). The knives should protrude 1
mm in order to t against moulding knives from Logosol.
- Check the knife level in the cutter head by placing a piece
of a planed board on the machine table behind the cutter.
The knives should then touch the board (see the picture
below). You can also use a magnetic adjuster (magnetic
adjuster, lower cutter, ref. no. 7500-001-0051): Loosen the
chip breaker’s lock screws, and screw down the knife’s
adjusting screws a couple of turns. Rotate the cutter head
so that the planing knife comes in its uppermost position.
Place the magnetic adjuster at and shaped as a ‘V’ on the
machine table behind the cutter, so that the edge of the knife
comes directly under the magnets of the magnetic adjuster.
Screw up the adjusting screws until the knife is lifted by the
magnet and by this gets the right height. Tighten the lock
screws and then carefully screw down the adjusting screws
so that they x the knife in this position.
- Tighten the lock screws (which x the knives) anticlockwise.
Tighten carefully at rst. Start from the sides, and move to
the next until you reach the middle, then retighten all screws
the same way.
- Carefully tighten the adjusting screws until they touch the
bottom of the indentations of the knives. If these screws are
screwed too tight, the knife will crack.
