Installing blades
CAUTION.
Always ensure that the saw is switched
off and unplugged from the mains supply before
removing or installing a blade.
1. Rotate the tension knob in an anti clockwise direction
to reduce the tension on the blade.
2. Remove the table insert (8) by raising it with a
screwdriver and sliding the insert off the blade
through the exit slot.
4. In order to cut effectively and avoid uncontrollable lifting
of the workpiece, the teeth of the scroll saw blade must
always point in a downward direction.
3. For pinned blades, pass the
blade through the centre hole
in the table, pass the blade
through the bottom arm slot
with the pin on the underside
of the arm attachment.
Apply a slight upward
pressure on the blade to
ensure the blade is locked
in place.
5. With the lower pined blade
securely attached to the lower
arm, keeping a slight upward
pressure on the blade, insert
the blade through the upper
arm locating slot with the pin
above the locating plate on
the arm.
Note.
A slight downward
pressure on the top moving arm may be required
to allow the blade to enter the slot with the pin above
the locating plate
6. Increase the tension on the
blade by turning the rear
tension knob in a clockwise
direction.
The tension of the blade should
then be adjusted when the
cutting operation is undertaken.
Higher tensions will be required
for tight curves etc. to reduce
blade deflection.
