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):
Have connection checked by a qual-
ified 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
t
20 m/
sec at dust extraction port).
