6.2.4. Adjusting tension of the saw blade
W arning!
Always disconnect the machine from the power source
while adjusting the blade tension!
Properly adjust the blade tension before use!
The saw blade is tensioned correctly when it runs
quietly and without vibrations. The saw blade also
must not run sideways off the wheels.
The band saw is equipped by a knob to adjust the
blade tension correctly. Proceed as follows:
1. Loosen the knob 2 (fig. 8) in direction A
2.Turn the knob (1) in direction (A) to tension or in
direction (B) to loosen the saw blade.
3.Tighten knob (2).
Caution!
An extremely tensioned saw blade may break and
damage the machine! Over-straining also causes poor
performance!
7. Operating the MICRO Band Saw
W
arning!
-To avoid injury from accidental start, make sure the
switch is in the OFF position and the plug is not
connected to the power source receptacle before
changing any parts.
-Please read the following safety regulations thor-
oughly and follow them before starting work with
the machine.
-Safe and precision working practice can only be
ensured with the unit properly secured!
-Do not leave the unit switched on, it unsupervised.
-Use only saw blades in good condition!
-Replace blunt and deformed saw blades immedi-
ately!
-Always disconnect the machine from the mains
supply for cleaning and service work!
-Do not run the machine unattended!
Note:
-Fasten the work piece securely. When sawing
round work pieces use an appropriate device to
secure the work piece against turning.
-Use the push stick when working close to the saw
blade.
7.1. Starting operation
Attention!
Before starting the band saw should be connected to
a dust extracting device.
Remove loose items and unnecessary work pieces
from the area before starting the machine
1. Connect the machine to the mains supply.
2.Switch the machine on with the power switch 4
(fig. 9 a)
7.1.1. Lockable Switch
Your MICRO Band Saw is equipped with a lockable
switch (fig. 9 b): It allows you to make the saw child-
proof and makes any other unauthorized use impracti-
cal as well. With the pulled-out pin like shown in the
sketch you cannot switch on the machine. So an acci-
dental start-up will be impossible and unauthorized
use is prevented.
An accidental start-up of the machine by a child or
visitor could cause injury!
To save the machine, set the switch in position “Off”,
pull out the pin and disconnect the machine from the
power source.
To start the machine again and to operate the switch
in the usual way, just push the pin back into its open-
ing. Then you can reconnect the machine to the power
source and work with it.
7.2. Adjusting blade speed
Before starting work, adjust the appropriate speed for
the saw blade and the material.
Vernier adjustment of the band speed is possible with
the speed regulator 3 (fig. 9 a). Refer to the diagram
(5) for optimal band speed. The values are, however,
only reference values!
Generally applicable:
High band speed for thin material and low band speed
for thick material.
7.3. Sawing
Mark the cut on the work piece. Never brake the band
speed by pushing too hard. The saw blade must ”cut
freely”, so the best results will be achieved. In case of
vibrations adapt the band speed respectively.
7.3.1. Free-hand sawing
Press the work piece onto the work table, guide it
carefully and only with little force (fig.10 a). More
pressure against the work table, less pressure against
the saw blade.
Always avoid awkward operations and hand positions
where a sudden slip could cause a hand to move into
the blade. In these cases use the push-stick (provided
with the saw, see fig. 10 b).
7.3.2. Sawing with miter guide
Attention!
Adjustments must only be carried out with the
machine switched off.
1. Adjust the desired angle on the miter guide.
2.Press the work piece lightly against the saw blade
(fig. 11).
7.3.2.1. Miter cuts
For miter cuts the working table can be tilted to any
angle between 0°and 45°.
