5. Transport and start up
5.1 Transport and installation
The machine is designed to operate in
closed rooms and must be bolted on a
firm and levelled table surface or on
the original cabinet stand.
5.2 Assembly
If you notice transport damage while
unpacking, notify your supplier
immediately. Do not operate the
machine!
Dispose of the packing in an
environmentally friendly manner.
Clean all rust protected surfaces with a
mild solvent.
Screw the handle (A, Fig1) into the
pinion shaft and tighten.

Fig 1
Use the handle to raise the machine
head to the up position. The handle is
spring loaded and can be repositioned
by pulling the handle away from the
head, and turned to the desired angle.
Attach the MDF table (F, Fig1) to the
base using two screws.
Attach the work stop (B, Fig1).
The work stop can be mounted on
either end of the table.
Attach the handles to the handwheels
(D, Fig1).
Adjust the depth stop (E, Fig1) and the
table stops (C, Fig1) according to the
work to be performed.
5.3 Mains connection
Mains connection and any extension
cords used must comply with
applicable regulations.
The mains voltage must comply with
the information on the machine licence
plate.
The mains connection must have a
10 A surge-proof fuse.
Only use power cords marked H07RN-
F
Connections and repairs to the
electrical equipment may only be
carried out by qualified electricians.
5.4 Dust collection
Use a suitable dust collection and
filtration system to avoid a high dust
concentration in the air.
Dust the machine down after each use
and as necessary.
5.5 Starting operation
You can start the machine with the
green on button. The red button on the
main switch stops the machine.
6. Machine operation
Set the depth stop rod (A, Fig2) to the
required depth of cut.
Fig 2
Adjust the work stop (B, Fig1) to suit
the workpiece length.
Place the workpiece on the table and
clamp the vice (A, Fig3).
The vice has a quick-release function;
one full turn to the left will disengage
the spindle.
Use the left handwheel to move the
table forward and backward to suit the
position of the mortise on the
workpiece.
Fig 3
Adjust the table stops (B, Fig3),
according to the length of cut required,
then tighten the thumb screws.
Turn on the machine and feed chisel
and bit steadily into the workpiece by
pulling down the operating handle.
NOTE:
The rate of feed must be fast enough
to prevent burning at the tip of the drill
bit, but not so fast as to cause the
machine to stall. The different rates of
feed for different woods must be
learned by experience.
After the first cut, the workpiece is
moved. The direction of movement
must allow the chips to clear freely
(Fig4).
Fig 4
When cutting deep mortises, make the
cut in several stages of approx. 25mm
each, to allow chips to clear.
To prevent breakout at the back of the
workpiece when cutting through
mortises, use a piece of scrap material
under the workpiece as support.
Warning:
Always keep your hands well clear of
the rotating bit.
Always close the chuck cover before
you start the machine.
Support long workpieces with helping
roller stands.
7. Setup and adjustments
General note:
Setup and adjustment work may
only be carried out after the
machine is protected against
accidental starting by pulling the
mains plug.
7.1 Installing chisel and bit
Disconnect the machine from the
power source (unplug).
Open the chuck access doors on both
sides of the head.
Insert the chisel bushing (3, Fig5) with
the hole facing forward into the head.
Insert chisel and bit together.

Tighten the screw (2, Fig5) just enough
to hold the chisel (4, Fig5) in place.
Fig 5
NOTE:
The slot in the chisel should face to the
right or left side only. The opening will
allow chips to escape during operation.
Push the chisel up as far as possible
into the head. Then lower the chisel
1,5 to 4mm, depending on the type of
wood being worked. Tighten the screw
to hold the chisel in place.
Push the bit up through the chisel
opening as far as it will go. Lock the
drill bit in place with the chuck key.
Loosen the screw and push the chisel
up against the bushing and tighten the
screw. This should provide the proper
distance between the points of the
chisel and the bit.
NOTE: The chisel should be adjusted
parallel. Use the workpiece as a gauge
(Fig 6).
Fig 6
Close the chuck access doors before
starting the machine.
Using bits with shorter shanks:
It will be necessary to attach the
spindle extension.
Place the supplied 32mm open
spanner on the chuck release nut and
use the chuck key to hold the chuck.
Force off the chuck with the chuck
release nut.
Attach the spindle extension to the
chuck and reinstall.
7.2 Sharpening chisel and bit
The chisel and bit should be kept
sharp for best performance.
Sharpen the bit by using a small file,
following the original shape of the bit.
File the inside edge of the spur (A,
Fig7), the sides of the centre point (B,
Fig7) and the cutting edge inwards
toward the flute of the bit (C, Fig7)
Fig 7
Do not file the outside edges of the
spur as this will affect the diameter of
the bit.
Sharpen the chisel on the cutting edge
inside only.
8. Maintenance and inspection
General notes:
Maintenance, cleaning and repair
work may only be carried out after
the machine is protected against
accidental starting by pulling the
mains plug.
The mortise requires only minor
maintenance, such as lubrication,
routine adjustments and sharpening of
chisel and bit.
Clean the machine regularly.
Defective safety devices must be
replaced immediately.
Repair and maintenance work on the
electrical system may only be carried
out by a qualified electrician.
9. Trouble shooting
Motor doesn’t start
*No electricity-
check mains and fuse.
*Defective switch, motor or cord-
consult an electrician.
Chisel clogged with chips
*Clearance chisel to bit not enough-
set bit 1,5 to 4mm below chisel.
*chips cannot clear the chisel-
observe chisel slot and working order.
Burned Wood
*Feed too slow-
increase feedrate.
*Worn chisel or bit-
sharpen chisel and bit.
