12. Repairs
A
Danger!
Repairs to power tools must be
carried out by qualified electricians
only!
Power tools in need of repair can be sent
to the service centre of your country.
Refer to the spare parts list for the
address.
Please attach a description of the fault to
the power tool.
13. Environmental protection
The machine's packing can be 100%
recycled.
Worn out power tools and accessories
contain considerable amounts of valua-
ble raw and rubber materials, which can
be recycled.
These instructions are printed on paper
produced with elemental chlorine free
bleaching process.
14. Trouble shooting
A
Danger!
Before carrying out any fault
service or maintenance work always:
− switch machine OFF.
− unplug power cable.
− wait until the band saw blade has
come to a complete stop.
Check to see that all safety devices
are operational after each fault serv-
ice.
Motor does not run
Undervoltage relay tripped by power fail-
ure:
− switch on again.
No mains voltage:
− check cables, plug, outlet and mains
fuse.
Motor overheated, e.g. by a blunt band
saw blade or chip build-up in the hous-
ing:
− remove cause for overheating, let
cool down for a few minutes, then
start again.
Motor and band saw blade turn in the
wrong direction
Incorrect phase sequence (only possible
on 400 V-models):
− turn phase changer inside the com-
bination switch/plug (see "Initial
operation").
Band saw blade coasting (≥ 10 s)
Electronic motor brake faulty:
− have ON/OFF switch replaced by a
qualified electrician.
Band saw blade wanders off the line
of cut or runs off the band saw
wheels
Band saw blade is not running dead cen-
tre on the band saw wheels:
− correct tracking (see "Care and
maintenance").
Band saw blade breaks
Incorrect tension:
− correct band saw blade tension (see
"Initial operation").
Load too high:
− reduce pressure against band saw
blade (reduced feed rate).
Incorrect band saw blade:
− replace band saw blade (see "Care
and maintenance"):
thin stock =
narrow band saw blade,
thick stock =
wide band saw blade.
Band saw blade warped
Load too high:
− avoid lateral pressure on the band
saw blade.
Saw vibrates
Insufficient mounting:
− Fasten saw properly to a suitable
surface (see "Initial operation").
Saw table loose:
− align and fasten saw table.
Motor mount loose:
− check fastening screws, tighten if
necessary.
Dust extraction port blocked
No dust collector connected or suction
capacity insufficient:
− connect a dust collector or increase
suction capacity (air speed ≥20 m/
sec at dust extraction port).
