Be careful when adjusting the side fences. The back fence is
to be level with the outermost cutting diameter of the cutter.
The two fences should be parallel with each other and set
so that the board is fed slightly diagonally (totally about 5
mm towards the left) through the machine. By this the feed
rollers will press the board against the fences.
If you are going to produce a large amount of a moulding
there is an additional locking screw to secure cutter 3.
The locking screw is recessed in a hole on the top of the
carriage.
Use in- and out-feed tables. Ensure that they are mounted
exactly at the same height as the machine table. Set the
out-feed table so that it slants upwards a couple of degrees.
By this the board will be pressed down against the table
when reaching the last cutter, which reduces the risk of
out-feed marks.
Reduce the air ow in the chip hose at cutter 2 when this
cutter is to take off little wood from the work piece. This will
increase the air ow at the other cutters.
If you want to keep a roughly sawn surface on one side of
the board, e.g. when making outdoor siding that is to be
painted, you let that side face the machine table and do
not start the lower cutter.
If you want to produce thinner three-sided mouldings than
the machine is designed to make, you can place a at board
on the machine table which will make the workpiece come
in a higher position in the machine.
Sometimes, it can be advantageous if the board is placed
on its edge when being machined, for instance when you
want an extra ne surface or when you want to have deeper
cuts than the lower cutter can make. In that case, you should
make extra high guides, preferably with ball bearings, that
are screwed to the cast iron table or the fences to keep the
workpiece in position when machining it.
The pressure springs of the feed rollers are to be set so
that the feed rollers balance on the workpiece. If the feed
rollers lie diagonally over the workpiece they can pull askew
and, in addition, the grooves in the rollers will make deep
marks in the workpiece. Balancing the feed rollers is extra
important when thin workpieces are machined. When
changing from the 2-12 m/min. feeder to the 4-24 m/min.
feeder, the pressure of the last feed roller has to be adjusted
due to the weight of the planetary gear.
Knives for the lower cutter (300 mm) may well be used in the
upper cutter too. They are cheaper and you can exchange
knives between the upper and the lower cutter.
Saving a moulding pattern
If you have produced a moulding that you know you will produce
in the future, it can be wise to take some measures before
removing the mounted knives. This will ensure that you can
quickly set the machine for making the same moulding again.
1. Save a 0.5 (1.6 ft) long piece of the machined moulding.
2. Keep the spacers you have used together with the knives
for the right and the left side cutter respectively.
3. Note the setting of the height scale of the table and the
rotating scale on the height adjusting crank, i.e. exactly note
to what height the machine table is set. Also measure the
machined moulding. Note the measurements of the saved
piece of moulding.
Quick mounting:
1. Mount the moulding knives and the spacers on the side
cutters.
2. Adjust the side fences using the setting rule.
3. Place the saved piece of moulding in the machine and set
the side cutter against the moulding.
4. Make sure the moulding piece lies against the side fence,
and push it in under the upper cutter. Raise the machine
table so that the planing knives touch the moulding piece.
Insert the moulding knives in the upper cutter and adjust
them laterally so that they t in the moulding pattern.
5. Fine-tune the height of the machine table by setting the
rotating scale according to the notes you have made.
