GUARD

Mounting

Adjusting

Blade Guard
See
instruction
3.
(iv)
— For Rip
Cuts:
(i)
Loosen
the 2
knobs
(H)
(Fig.
23) and
slide
the
riving
knife bracket
(B)
down until
the tip of the
riving
knife
(C)
is
approximately
10mm
(%")
from
the
surface
of
the
machine's worktable.
The
distance
of the
riving
knife
from
the
blade must
be
between
1-3mm.
(adjust
by
loosening
the
screws
(G) and
sliding
the
knife
left
or
right
within
the
bracket
slots).
(ii)
Loosen
the
knob
(Q) on the
back
of the
guard
and
lower
the
bracket
(D)
until
the
central spring
on the
bottom
of the
bracket just
touches
the
surface
of the
timber (i.e. when
the
tips
of all
anti-kickback
fingers
(L)
are
positioned
at
about
1
/
8
"
below
the
surface
of
the
wood before
you
start
to
feed
the
timber
into
the
blade).
Once
the
anti-kickback fingers
have
come
into
contact
with
the
surface
of the
timber,
they
should
be at the
angle indicated.
Important:
It is
essential
for
safe rip-cutting that
the
anti-
kickback fingers
are
correctly positioned
•
they
prevent
the
tendency
of the
blade
to
throw
the
timber back towards
the
operator.
Note that
the
alien
screw mounting
the
anti-
kickback fingers onto
its
support bracket
can
be
loosened
to
allow
the
kickback fingers
to
be
angled
for
bevel-ripping.
It
is
also important
to use the
riving knife
in its
correct position when
ripping
to
prevent
the
timber
binding
on the
blade.
—
For
Cross-Cutting:
Neither
the
riving knife
nor the
anti-kickback fingers
are
needed
for
cross -cuts,
so
make sure that they
are
both
adjusted
up out of the
way.

Removing

Blade
Guard
5.4
Removing
the
Sawblade
Follow
the
mounting procedure
(3.(iv))
in
reverse order.
The
arbor
nut has a
left-hand thread,
so it is
necessary
to
turn
it
clockwise
to
remove
it
from
the
motor
shaft.
(i)
Fit the
large alien
key
supplied into
the
front
end of
the
motorshaft
to
hold
the
shaft steady.
(Note
that
the
brass
arbor
nut has an
inner
circular
ring
rather
than being hexagonal across
its
full width
- the nut
should always
be
mounted with this inner ring facing
the
motor).
(ii)
Fit the
large open-ended spanner onto
the
arbor
nut
as
near
parallel
to the
alien
key as
possible.
(iii)
Holding
the
alien
key
firmly with
one
hand,
turn
the
large
spanner clockwise with
the
other hand
and the
nut
will loosen.
(iv)
Remove
the
blade
and all
flanges
on the
motor shaft
noting
the
order
of
assembly
and
positioning
for
when
you
remount
the
blade.
If
the nut is
difficult
to
loosen
in
this way,
use the
following method:
Lock
the
roller
head
in
position
on the arm
with
the
rip
lock.
Fit
the
large spanner
to the
arbor
nut
only.
Position
a
striking block
of
wood
as
shown
in
Fig.
24.
(iv)
Hold
the
spanner
on the
nut, while
at the
same time,
with
some
force, turning
the
blade/motor shaft anti-
clockwise until
the end of the
spanner strikes
the
block
and the nut
loosens.
CAUTION:
TAKE CARE
NOT TO
CATCH
YOUR
HAND
ON THE
EXPOSED TEETH
OF THE
BLADE
AND
NEVER
TRY TO JAM THE
MOTOR
FAN AS A
MEANS
OF
HOLDING
THE
SHAFT STATIONARY
Rotate
spanner
anti-clockwise
