• Release the safety nut of the clamping sleeve using
the key supplied, Fig. 16.
• Insert the clamping sleeve in the nut, or remove it.
• Firmly tighten the nut in the clamp while keeping the spindle
locked. Before every use of the machine make sure that
the cutting tool is firmly clamped at the end of the spindle.
• Set the reducing piece for the opening back to its origi-
nal position.
• Adjust the fence, as required, by means of the scale
on the table.
• Connect the dust extractor unit. It is highly recom-
mended to connect a dust extractor unit (or system) in
order to keep the opening free from chips, to cool the
motor, and to facilitate the work piece feed.
• Reconnect the machine to the power supply.
Setting the moulding fence
The use of the fence is a must. Every job must be looked
at separately. At every new use you must make sure that
the guards are correctly installed and adjusted.
For every new use, each pressure piece on the fence
must be newly set.
Make sure that all the bolts are firmly tightened before
you start moulding.
Use of the table rings
The table rings must be used in order to reduce the
spacing between table and spindle to a minimum.
Before switching on the machine systematically check
the table rings supplied for their correct seat.
Check whether you have chosen the correct ring for the
corresponding cutting tool and its installation height, in
order to reduce the risk of work piece tilting at passing
the opening.
The reduction piece (table ring) must enclose the cutter
head as far as possible.
Adjustments
Adjust the number of revolutions Fig. 18
The speed adjustment of the machine has 6 stages.
• Determine the optimal number of revolutions by a
sample cut in a piece of waste material.
Note: The use of the correct number of revolutions in-
creases the life-span of the drill. It, also, affects the
worked surface of the work piece.
Adjust the rabbet, Fig. 19, 20
• The rabbet is to be stopped to the size of the work
piece and the milling tool.
• Loosen the 2 plastic cap screws (b) on the back of
the fence.
Set the stops and pressure devices such that they
ensure the safe guidance of the workpiece at the in-
put and output section of the machine.
Fig. 20
• Push the rabbet to the rear or forward of the desired
position. Use scale (c) on the table in order to deter-
mine the distance and take note of the drill centre.
• Re-tighten the 2 plastic cap screws (Fig. 19, b) on the
back to keep the fence in this position.
22 GB
Adjust the rabbet for error, Fig. 20
• Error from wood is the material from wood left from
the drill exiting, more thinly than the material, on the
right side.
• The left fence must be adjusted to the thinner mate-
rial. It supports the material and ensures a more exact
cut. To do this, loosen the plastic cap screws, push the
fence to the front and tighten it.
Installing and adjusting the pressure limits, Fig. 21
The pressure limits (5) are designed so that the work
piece is held on the spot and setback is avoided.
• Drive milling cutter to the lowest position
• Insert the workpiece to be machined and press the
pressure bar onto the workpiece with light pressure.
• Remove workpiece.
• Set the milling cutter to the desired height (see: Set-
ting the working depth).
Adjust the Cross-cutting jig, Fig. 22
• Slide horizontal along the table the cross-cutting jig (8)
in order to implement clean up error and mitre cuts.
• In order to stop the jig at the desired angle, loosen
the locking knob of the cross-cutting jig and turn this
to the desired angle.
Tighten the locking knob of the jig (8) again.
Fig. 21
Always make a sample cut in a piece of waste mate-
rial in order to guarantee that the attitudes are correct.
Switching on and off, Fig. 18
Make sure that all keys and adjusting tools are well away
from the spare desk that the attitudes are installed in full
and all safety covers are kept.
O - Out
I - On
This machine uses an electromagnetic switch for op-
timal security. Whenever the current is interrupted the
machine stops immediately. To restart the machine the
green button must be pushed again
Utilization of the machine
• Insert an appropriate milling cutter in the tool holder
and secure this by tightening the tool holder nut
(Fig. 17, item 14).
• Fit and secure the cutting knives.
• Adjust the speed, and adjust the output fence in such
a way that the material cut is supported and a com-
pensation for the material removed is achieved.
• Switch the machine on.
• Make sure the work piece is firmly pressed against
the fence.
• Push the work piece softly from right to left against the
turning direction of the tool.
• Keep your forwarding speed constant. Do not push too
fast – it would slow down the motor too much.
• Feeding the work piece too fast will result in a poor
cutting quality. There is also the risk of damaging the
cutting knives or the motor.
• Feeding the work piece too slow will result in burnt
spots on the work piece.
