proper working order:
− band saw blade;
− upper and lower blade guard.
• Replace damaged parts immedi-
ately.
• Assume correct work position
(the band saw blade's teeth must
point towards the operator).
• Never cut more than one workpiece at a time – and also no bundles containing several individual
pieces. Risk of personal injury if
individual pieces are caught by
the saw blade uncontrolled.
c
Drawing-in/trapping hazard!
• Do not wear loose clothing, jewellery, or gloves, which may get
caught and wound up by revolv
ing machine parts.
• Contain long hair with a hairnet.

ming workpiece!
When sawing with the rip fence and a
tilted saw table, the rip fence must be
installed on that side of the saw table
which is tilted downward.
4. Set upper blade guide 3 mm above
the workpiece.
Note:
3
Always make a trial cut in a piece
of scrap to verify settings; correct if necessary before cutting the workpiece.
5. Place workpiece on the saw table.
6. Start saw.
7. Cut workpiece in a single pass.
8. Switch off if no further cutting is to
be done immediately afterwards.
9. If no further cutting is to be done
immediately afterwards: decrease
the bandsaw blade tension and
attach a notice indicating that the
bandsaw blade tension must be
reset prior to the next cutting opera
tion to the machine (see 'Tensioning
the bandsaw blade').
8. Care and Maintenance
A
Danger!
Prior to all servicing:
1. switch machine OFF;
2. Wait for saw blade to stop
3. Unplug mains cable.
− Check that all safety devices are
operational again after each service.
− Replace damaged parts, especially
safety devices, with genuine
replacement parts only, since parts
not tested and approved by the
manufacturer can cause unforesee
able damage.
