Height adjustment of the table insert
(if necessary)
The table insert (4) is set correctly when its
surface is 0 mm to 0.7 mm below the table
surface.
Adjust the 4 screws in the corners of the table
insert (4) to adjust the height.
7.2 Connection to Power Mains
Danger! High voltage
• Operate the device in dry surroundings
only.
• Operate machine only on a power source
meeting the following requirements (see
also “Technical Specifications”):
– outlets properly installed, earthed and
tested;
– mains voltage and system frequency
conform to the voltage and frequency
shown on the machine´s rating label;
– Fuse protection by a residual current
circuit breaker (RCCB) of 30 mA sensi-
tivity;
Note:
Check with your local Electricity Board or
your electrician if in doubt whether your
house service connection meets the
requirements.
• Make sure the power supply cable is out of
the way, so that it does not interfere with
the work and does not pose a tripping
hazard or will get damaged.
• Protect the power supply cable from heat,
aggressive liquids and sharp edges.
• Use only rubber-jacketed extension cables
with sufficient lead cross-section.
• When working out of doors, only use
extension cables that are also approved for
outdoors.
• Do not pull on the power supply cable to
unplug.
• Avoid accidental start-up: ensure that the
on/off switch is switched off when inserting
the plug in the socket.
Risk of injury!
This saw may only be operated by one
person at a time. Other persons shall stay
only at a distance to the saw for the purpose
of feeding or removing stock.
Before starting work, check to see that the
following are in proper working order:
– power cable and plug
– ON/OFF switch
– Splitting wedge
– Blade guard
– feeding aids (push stick, push block and
handle).
Use personal protection gear:
– dust respirator;
– ear protection;
– safety goggles.
Assume proper operating position:
– at the front of the saw;
– in front of the saw;
– to the left of the line of cut;
– when working with two persons, the other
person must remain at an adequate dis-
tance to the saw.
If the type of work requires, use the follow-
ing:
– suitable workpiece supports – if other-
wise workpiece would fall off the table af-
ter cutting;
– dust collector.
Avoid typical operator mistakes:
– Do not attempt to stop the saw blade by
pushing the workpiece against its side.
Risk of kickback.
– Always hold the workpiece down on the
table and do not jam it. Risk of kickback.
– Never cut several work pieces at the
same time – and also no bundles contain-
ing several individual pieces. Risk of per-
sonal injury if individual pieces are
caught by the saw blade uncontrolled.
Entangelement hazard!
Never cut stock to which ropes, cords,
strings, cables or wires are attached or which
contain such materials.
8.1 Dust extraction unit / all-purpose
vacuum cleaner
Danger!
Dust of certain timber species (e.g. beech,
oak, ash) can cause cancer when inhaled.
Use a suitable dust extraction unit when
working in enclosed spaces.
In addition, use a dust mask, as not all saw
dust is collected or extracted.
Operation without a suitable dust collector is
only possible out of doors.
The dust extraction unit must meet the following
requirements:
• Suitable for the diameter of the suction nozzles
(chip box 35/44 mm);
• air flow volume

460 m
3
/h;
• Underpressure at the saw’s suction nozzle
 530 Pa;
• Air speed at the saw’s suction nozzle

20 m/s.
The suction nozzles (30) for extraction of the
chips are located on the blade guard.
Observe the dust collector's operating
instructions as well!
8.2 Setting the depth of cut
Danger!
Body parts or objects in the adjustment area
can get caught by the running saw blade! Set
depth of cut only with saw blade at standstill!
The saw blade's cutting depth needs to be
adapted to the workpiece’s height: the blade
guard shall rest with its front edge on the
workpiece.
• Adjust the cutting depth by turning the
handwheel (18) as required.
Note:
In order to balance eventual play in the
adjustment of the cutting height, always
move the saw blade from below into the
desired position.
8.3 Setting the saw blade tilt
Danger!
Body parts, objects or machine parts in the
adjustment area can get caught by the
running saw blade! Set the depth of cut only
with the saw blade at standstill!
The blade bevel angle can be adjusted between -
1.5° and 46.5°.
1. Release clamping lever (19).
2. Set the desired saw blade inclination by
turning the hand wheel (17).
3. Lock the set inclination by tightening the
clamping lever (19) (turn clockwise).
Setting for undercutting
The blade tilt setting has end stops at 0° and 45°.
For special bevel cuts (undercutting) the bevel
angle can be increased by 1.5° in both directions.
• Withdraw bevel angle limitation stop (20) and
place over the right-hand cam plate = bevel
angle of saw blade adjustable between –1.5°
and 45°.
• Withdraw bevel angle limitation stop (20) and
place over the left-hand cam plate = bevel angle
of saw blade adjustable between 0° and 46.5°.
ON/OFF Switch
• switch on = press upper switch (15) for 1 - 2
seconds.
• switch off = press lower switch (16).
