10.1 Replacing the bandsaw blade
HAZARD!
Take great care when
unpacking the bandsaw blade as they
are usually folded and can spring out
very suddenly with great force.
TIP:
If the new blade being fitted is a
different width to the one being removed,
it is advisable to move back and slacken
off all blade guides before fitting the
new blade as this will make fitting easier.
Whenever a different size blade is fitted
the blade guides will always need re-
setting.
1.
Isolate the machine from the power
supply.
2.
Open the top and bottom bandwheel
doors.
3.
Remove the rip fence and rip fence
rail.
Fig 10.1
.
4.
Undo the blade tension knob on the
top of the machine, this will lower the
top bandwheel and allow the blade to be
removed.
5.
Remove the bandsaw blade by
feeding it through the slot in the table,
upper blade guides & guard and slot in
the spine of the machine taking care not
to cut yourself, wear gloves if necessary.

6.
Fit the new blade around the
bandwheels ensuring the blade teeth are
pointing downwards and towards you
at the position where the blade passes
through the table.
• Ensuring that the blade is fully in place
on the bandwheel re-apply tension using
the tensioning knob.
• adjust the blade tension until you
are happy with the blade tension (
see
section 5.4
for tensioning guidelines)
7.
Check the blade tracking on the newly
fitted blade by turning the upper wheel
by hand. To track the blade loosen the
lock knob and turn the tracking wheel
Fig 10.3
; clockwise to move the blade
back and anti clockwise to move the
blade forward. The blade should run as
close to the centre of the bandwheel as
possible (
see section 5.5
).
8.
Re-set the blade guides
(see sections
6.3 & 6.4)
9.
Close and lock both the bandwheel
doors, refit the fence rail and rip fence
before re-connecting the power supply.
CAUTION!
Before carrying out any adjustments
or maintenance ensure that the
machine is isolated and disconnected
from the electricity supply.
