10. Working instructions

The following recommendations are examples for safe
use of the band saws.
The following safe working methods are considered to
contribute to safety but may not be appropriate, fully
or extensively applicable for every use. They cannot
cover all possible hazardous conditions and must be
interpreted carefully.
• When working in enclosed spaces, connect the ma-
chines to a chip extraction system.
• If the machine is not in operation, e.g. work is com-
plete, slacken the saw band. Attach a corresponding
note to the machine for the next user about the ten-
sioning of the saw band.
• Store unused saw bands together and safely in a dry
place. Check for faults (teeth, cracks) before use. Do
not use defective saw bands!
• Wear suitable gloves when handling saw bands.
• Before starting work, all guards and safety devices
on the machine must be securely fitted.
• Never clean the band saw blade or the band saw
blade guide with a hand-held brush or scraper if
the band saw blade is running. Resinous band saw
blades jeopardise work safety and must be cleaned
regularly.
• Wear safety goggles and hearing protection when
working for your personal protection. Wear a hair net
with long hair. Roll loose sleeves up above the elbows.
• Always position the band saw blade guide as close
as possible to the workpiece when working.
• Make sure that the lighting conditions in the working
and surrounding area of the machine are sufficient.
• Always use the rip fences for straight cuts in order to
prevent the workpiece from tilting or slipping.
• Use the push stick for processing narrow workpiec-
es with manual advance.
• For angled cuts, bring the saw table into the appro-
priate position and guide the workpiece along the
longitudinal stop.
• In order to cut dovetail tenons and teeth or wedges,
swivel the saw table into the plus and minus position.
Ensure that the workpiece is guided safely.
• On curved and irregular cuts, advance the work-
piece using both hands, keeping your fingers closed.
Keep your hands on a safe area of the workpiece.
• For repeated cutting of curve, irregular cuts, use an
auxiliary template.
• Secure the workpiece against turning when cutting
round pieces of wood.

• For safe work when transverse cutting, use the spe-
cial mitre gauge accessory.
10.1 Performing longitudinal cuts (Fig. AD)
Here, a workpiece is cut in its longitudinal direction.
• Set the parallel stop (5) on the right or left side of the
saw band according to the desired width.
• Lower the saw band guide (4) onto the workpiece.
(see 8.9)
• Switch on the saw.
• Press one edge of the workpiece against the parallel
stop (5) with the right hand, whilst the flat side lies on
the saw table (7).
• Slide the workpiece at an even feed rate along the
parallel stop (5) into the saw band.
• Important: Long workpieces must be secured
against tilting at the end of the cutting process (e.g.
with roller stand, etc.).
• Attention! When processing narrower workpieces it
is essential to use a push rod.
• The push stick (ae) must always be stored within
reach, on the hook (ad) provided for this purpose on
the side of the saw. (Fig. AB)
10.2 Performing angled cuts (Fig. J + Fig. AE)
• In order to execute angled cuts parallel to the saw
band, it is possible to tilt the saw table (7) forwards
from 0° - 45°.
• Loosen the locking handle (k).
• Tilt saw table (7) forwards, until the desired angle is
set on the degree scale (e).
• Tighten the locking handle (k) again.
• Attention: With a tilted saw table (7), the parallel stop
(5) must be positioned on the downward facing side
to the right of the saw band in the working direction
(if the workpiece width allows this), in order to se-
cure the workpiece against slipping.
• Perform the cut as described under 10.1.
10.3 Freehand cuts (Fig. AF)
One of the most important features of a band saw is the
ease with which it can cut curves and radii.
• Lower the saw band guide (4) onto the workpiece.
(see 8.9)
• Switch on the saw.
• Press the workpiece firmly onto the saw table (7)
and slowly slide into the saw band.
• During freehand cutting you should always work
with a low advancing speed, so that the saw band
can follow the desired line.
