9. Before commissioning
m ATTENTION!
Always make sure the device is fully assembled
before commissioning!
Check all screws and connections for firm seating.
Check that the saw band is in perfect condition.
Remove all tools from the clamping jaw and the
saw table.
• The saw band must be able to run freely.
• In case of previously machined wood, be aware of
any foreign objects, such as nails or screws, etc.
• Before pressing the on/off switch (5), make sure that
the saw band is correctly fitted, and that moving
parts run smoothly.
• Before connecting the machine, make certain that
the data on the type plate matches with the mains
power data.
9.1 Switching the machine on (Fig. 4)
CAUTION:
Before connecting the machine to the mains power
supply, always make sure that the on/off switch (5) is
functioning properly.
1. To switch the machine on, press the on/off switch
(5) and the release switch (6) at the same time.
2. To switch off, release the on/off switch (5).
3. Attention: The saw band runs after the device
has been switched off.
9.2 Handle (Fig. 5)
m For safety reasons, please disconnect the power ca-
ble from the mains.
The handle (1) allows the user to maintain a firm hold
during use.
1. Put the handle (1) in a comfortable and secure
working position.
9.3 Switching the LED lamp on (Fig. 1)
1. To switch the LED (3.1) on, set the on/off switch
(3) to "I (ON)". To switch the machine off, set the
switch to position "O (OFF)".
2. NOTE: Wipe any dirt off the LED (3.1) with a dry
cloth. Be careful to avoid scratching the LED
(3.1), because this can severely reduce the light
intensity.
3. Do not use thinners or spirit to clean the LED
(3.1). Such solvents may damage the LED.
4. Always switch the LED (3.1) off after work.

9.4 Speed setting wheel (Fig. 4)
m CAUTION:
Never change the speed with the device running.
1. The machine speed can be set between 0.7 m/s
and 2.2 m/s by turning the speed setting wheel
(4).
2. By turning the speed setting wheel (4) towards
the number 6 you increase the speed, whilst
turning it towards 1 reduces the speed.
m CAUTION:
The speed setting wheel (4) can only be turned
up to 6 and back to 1. If it is forcibly turned past
6 or beyond 1, it may no longer be possible to
adjust the speed.
3. Choose a suitable speed for the workpiece to be
cut.
9.5 Adjusting the workpiece stop (10) (Fig. 6)
m For safety reasons, please disconnect the power ca-
ble from the mains.
While using the metal band saw, the workpiece stop
(10) must be secured in the lowest position.
1. If the workpiece stop (10) should butt against an
obstacle at the end of a cut, e.g. a wall or similar,
loosen the screw (see fig. 6) and slide the work-
piece stop (10) upwards. Secure the workpiece
stop (10) after sliding by fixing the screws again.
2. Attention: Ensure that the metal band saw is
switched off when adjusting the workpiece stop
(10)!
10. Operation
10.1 Tips for better sawing (Fig. 14)
The following recommendations should be applied as
a guideline (see "Recommended sawing positions" ta-
ble in figure 14).
• Never twist the saw band during the cutting pro-
cess.
• Never use liquid coolant for the metal band saw.
The use of liquid coolants causes deposits on the
rubber belts (17) and reduces the cutting perfor-
mance.
• If severe vibrations arise during the cutting process,
make sure that the sawn workpiece is securely
clamped. If the vibrations continue, replace the saw
band (see chapter 13 "Cleaning and maintenance").
10.2 Sawing process without saw table (Fig. 13)
m Warning!
Only adjust or reload workpieces when the metal band
saw is at a standstill.
1. Clamp the workpieces to be sawed in a vice or
in another clamping device, i.e. directly between
the two clamping jaws and without placing other
objects in between.
2. Bring the workpiece stop (10) in contact with the
workpiece, and whilst doing so hold the saw band
away from the workpiece.
3. Then switch the metal band saw on. To do this,
press the on/off switch (5) and the release switch
(6) at the same time.
4. Once the metal band saw has reached the de-
sired speed, tilt the main body of the machine
slowly and cautiously such that the saw band (11)
comes into contact with the workpiece. Do not
apply any additional pressure. Be careful to avoid
the saw band (11) coming suddenly and abruptly
into contact with the surface of the workpiece.
This results in serious damage to the saw band.
In order to achieve the maximum service life of
the saw band, ensure that no sudden impacts
arise at the start of the sawing process.
5. Straight cuts can be achieved if the saw band is
flush with the side surface of the engine hous-
ing. Be aware of your viewing angle in this case.
Twisting the saw band or holding it at an angle
causes the cut to run alongside the cutting line,
and this reduces the service life of the saw band.
NOTE: If the band saw becomes jammed or stuck
in the workpiece during sawing, release the on/off
switch (5) immediately to avoid damage to the saw
band and engine.
6. The net weight of the metal band saw delivers the
most efficient cutting pressure. If the pressure is
increased by the operator, the saw band (11) be-
comes slower and the service life of the band is
reduced.
7. End pieces that are so heavy they would cause
injuries if they were to fall should be supported.
Wearing safety shoes is strongly recommended.
Attention: End pieces may be hot and sharp.
8. Hold the metal band saw tight in both hands when
sawing.
9. Prevent the metal band saw from falling against
the clamped or supported workpiece after cut-
ting.

10.3 Clamping the workpiece (Fig. 16-18)
1. First, open the workpiece clamping lever (25)
anti-clockwise.
2. Pull the moving clamping jaw (24) back.
3. Place the workpiece on the front fixed clamp-
ing jaw (23).
4. Slide the moving clamping jaw (24) toward the
workpiece.
5. Clamp the workpiece using workpiece clamping
lever (25) anti-clockwise.
10.4 Mitre cut 0°- 45° (Fig. 19)
Mitre cuts of 0°-45° to the working surface can be car-
ried out using the metal band saw.
• To do this, open the locking handle (graduated
scale) (26).
• Set the support arm base plate (22) to the desired
angle.
• Re-tighten the locking handle (graduated scale)
(26).
10.5 Sawing process with the saw table (Fig. 20
+ 21)
m Attention
Keep the mains cable away from the sawing area dur-
ing the sawing process.
m Risk of injury! Keep your hands away from the
sawing area.
Mitre cuts of 0°- 45° to the working surface to the left
can be carried out using the metal band saw.
1. Set the desired angle as described under point
"10.4 Mitre cut 0°- 45°".
2. Clamp your workpiece as described under point
"10.3 Clamping the workpiece".
3. Switch the metal band saw on. To do this, press
the on/off switch (5) and the release switch (6)
at the same time.
4. Once the metal band saw has reached the de-
sired speed, pull the safety bolt (27) (see fig.
3) and tilt the main body of the metal band saw
slowly and cautiously downwards so that the saw
band comes into contact with the workpiece. Do
not apply any additional pressure. Be careful to
avoid the saw band coming suddenly and abrupt-
ly into contact with the surface of the workpiece.
This results in serious damage to the saw band.
In order to achieve the maximum service life of
the saw band, ensure that no sudden impacts
arise at the start of the sawing process.
