• Turn the upper band wheel by hand in the cut-
ting direction and carry out the side correction
with the hand grip (Fig.4 "C").
• After successful adjustment, tighten the wing
nut on the hand grip.
You can adjust the upper saw band guide up to
250 mm work piece height (Fig. 6). Keeping the
distance to the work piece as small as possible to
ensure optimal band guidance and safe work!
Rotational speed adjustment
Caution: Pull out the plug!
• Open the saw band guard and secure it with
the bar.
• Loosen the tommy screw (Fig.7 "A") on the
side of the motor; relax the belt. Change belt as
The following recommendations are examples
for the safe use of band saws.
The following safe work methods are considered
contributions to safety, but they are not suitable
for every use, complete or universally applicable.
They cannot cover all potential dangerous condi-
tions and must be interpreted carefully.
• Before every use, check all protective and safe-
ty equipment for functionality.
• It is only possible to saw with the band saw
when the saw band cover is closed. Thus, the
saw band cover can be opened only when the
machine is stopped.
• Regularly open the saw band cover and remove
sawdust from the machine.
• Only use saw bands with a minimum width of
6 mm and a maximum width of 20 mm. The
thickness must be 0.65 mm.
• Test the functionality of the emergency stop
before every start-up.
• Test the functionality of the end switch when the
D GB
doors are open before every start-up.
• When working in closed rooms, the machine
has to be attached to a extraction system.
This is also recommended when working out-
side. For work in the industrial sector, a vacuum
that meets the industrial regulations must be
The installed electric motor is connected and
ready for use.
The connection conforms to the applicable
VDE and DlN regulations.
The customer-side mains connection and the
extension cord used must meet these regula-
tions.
Installations, repairs and maintenance tasks
to the electrical installation may be carried out
only by a professional.
Important Notes
The electric motor is designed for Operation
Type S 1.
If the motor is overloaded, it switches off
automatically. After a cool-down period (which
varies in length), the motor can be switched
on again.
Damaged electrical cords
Insulation damage often occurs to electric power
cables. Causes are:
1. Pressure points, if cords are run through win-
dow or door gaps.
Carry out retrofitting, adjustment, measure-
ment and cleaning tasks only when the motor
is switched off. Pull the plug and wait for the
rotating tool to come to a stop.
As an experienced craftsman, you may carry
needed.
• Now set the desired rotational speed:
Step 1 = 1200 m/min
Step 2 = 800 m/min
• Bring the belt to tension and tighten the tommy
screw again. Finally, close the saw band guard.
Counterthrust bearing
The counterthrust bearing (Fig.8 "A") absorbs the
feed pressure of the work piece.
Adjust the upper and the lower counterthrust
bearing such that it lightly runs along the back of
the saw band.
Guide rollers
Adjust the upper and lower guide rollers (Fig.
8 "B") to the respective saw band width. The
Work Hints
installed.
• When the machine is not being used, e.g. at the
end of work, relax the saw band. Attach a note
to the machine for the next user to tension the
saw band.
• Store unused saw bands folded and securely
in a dry place. Before use, check for defects
(teeth, cracks). Do not use defective saw bands!
• Wear suitable gloves when handling saw bands.
• Before beginning work, all protective and safety
equipment must be mounted on the machine.
• Never clean the saw band or the saw band
guide with a handheld brush or scraper while
the saw band is running. Saw bands coated
with resin endanger the work safety and must
be cleaned regularly.
• For your personal protection while working,
wear safety glasses and hearing protection. If
you have long hair, wear a hair net. Roll loose
sleeves up to above the elbows.
• While working, always position the saw band
guard as close as possible to the work piece.
• Provide sufficient lighting in the working and
surrounding area of the machine.
• For straight cuts, always use the longitudinal
fence to prevent the work piece from tipping or
slipping away.

2. Bent points, due to improper securing or run-
ning of the cords.
3. Cut points due to running over the cords.
4. Insulation damage due to ripping out the plug
from the wall socket.
5. Cracks due to aging of the insulation.
Do not use such damaged power cords and
they
pose life-threatening danger due to the insula-
tion damage.
Regularly check power supply cords for damage.
Make sure that during such checks, the cord is not
connected to the mains voltage.
Power supply cords must adhere to the relevant
VDE and DIN requirements. Use only cords label-
led HO 7 RNF. An imprint of the classification on
the cords is required.
Alternating current motor
1. Mains voltage must be 230 V/50 Hz.
2. Extension cords must have a cross-section of
1.5 mm² up to a length of 25 m, over 25 m at
least 2.5 mm².
3. The mains connection is slow-blowing fused

leading edge of the guide rollers may reach up to
the highest tooth depth of the saw band. When the
guide rollers lightly touch
the saw band, lock the position of the rollers with
the knurled screw.
The saw band must not jam!
Push stick and push handle, Fig. 12 + 13
• When cutting narrow work pieces, with a
distance between the saw blade and the fence
rail being less than 120 mm, you must use the
push stick (A).
• When pushing small, specially formed work
pieces, use the push handle (B). The individual
push blocks can be made by you and attached
to the push handle.
• For flat cuts with thin work pieces, use the low
end of a fence so that the adjustable separating
guard can be used.
• To process small work pieces with manual feed,
use the push stick (especially if you will be
pushing past close to the saw band).
• For oblique cuts, bring the saw table into the
corresponding position and guide the work
piece along the longitudinal fence.
• To cut dovetail joints and tenons or keying,
pivot the saw table respectively in the plus and
minus position. Pay attention to safe work piece
guidance.
• For arched and irregular cutting of the work
piece, push the piece forward steadily with both
hands, keeping the fingers closed. Grip the
work piece with the hands in the safe area.
• For repeated execution of arched, irregular cuts,
use an auxiliary template.
• To cut small keys, use a guiding device.
• For safe work with cross cuts, use the special
accessory rip fence.
• For safe work when cutting round plates use a
circle-cutting device.
• Make sure that push stick and push wood are
regularly replaced.
