Changing a blade
DANGER! Never try to use a blade larger than the stated
capacity of the saw. It might come into contact with
the blade guards. Never use a blade that is too thick to
allow the outer blade washer to engage with the flats on
the spindle. It will prevent the blade screw from properly
securing the blade on the spindle. Do not use the saw to
cut metal or masonry. Ensure that any spacers and
spindle rings that may be required suit the spindle and
the blade fitted.
1. Make sure that the electrical plug is removed from the
power point.
2. Push down on the
operating handle (7) and
pull the release knob (6)
to disengage the saw arm
(5). The release knob (6)
can be turned so that it
is held in the retracted
position (fig. b).
3. Raise the saw arm (5) to
its highest position.
4. Using a Phillips head
screwdriver loosen and
remove the screw that
secures the guard retraction
arm (13) to the rotating
blade guard (fig c).
5. Using a Phillips head
screwdriver loosen (fig. d)
and remove the screw that
secures the blade bolt
cover (14).
6. Pull the rotating blade
guard (12) down then
swing it up together with
the blade bolt cover (14).
When the rotating blade
guard (12) is positioned
over the upper fixed blade
guard (9) it is possible
to access the blade bolt
(fig. e).
7. Hold the rotating guard
(12) up and press the
spindle lock button (26)
(fig. f). Rotate the blade
until the spindle locks.
8. Use the 6mm hex key
provided to loosen and
remove the blade bolt.
(Loosen in a clockwise
direction as the blade
screw has a left hand
thread) (fig. g).
9. Remove the flat washer
and outer blade washer
and the blade.
10. Wipe a drop of oil onto
the inner blade washer
and the outer blade
washer where they
contact the blade.
11. Fit the new blade onto
the spindle taking care
that the inner blade
washer sits behind the blade (fig. h).
CAUTION. To ensure correct
blade rotation, always install
the blade with the blade
teeth and the arrow printed
on the side of the blade
pointing down. The direction
of blade rotation is also
stamped with an arrow on
the upper blade guard.
