(i)
With
the

in the 0°
position.

mitre clamp.
(ii)

as
shown
in
Fig.
10.
(ill)
Release
the
mitre latch
and
depending
on
which
way
the
arm
needs
to
move
to
give
the
true
90°
crosscut
required, loosen
and
tighten
the
adjusting
flanges
on
either
side
of the arm
(Fig.
11)
if the
front
of the arm
needs
to go to the
left,
loosen
the
adusting
flange
on
the
right
of the arm and
tighten
the
flange
on the
left.
If
the
opposite
is the
case,
and the arm
needs
to
move
to the
right, loosen
the
adjusting
flange
on the
left
and
tighten
the
flange
on the
right.
Adjust
the
flanges
a
little
at a
time
and
re-engage
the
mitre
latch
and
clamp
and
check
the
crosscut travel
of the
blade
relative
to the
fence
with
a
square.
Do not
overtighten
the
adjusting flanges
or the
mitre
latch
will
be too
stiff
to
operate
easily.
(iv)
Once
satisfied
that
the
crosscut travel
is
accurate,
retighten
the
lock nuts
on
each side
of the arm (as in
Fig.
10).
(v)
Adjust
the
pointer
on the
mitre scale
so
that
it
registers
0° in
this
position.

4.2. Checking
the
Saw
Blade
is
Parallel
to
the Arm
Tracks.
This check
is to
ensure that,
in the
straight
90°
cross-
cut
position,
the
blade
runs true across
the
table
and
does
not
run
"dog fashion" (Fig.
12).
If the
blade
is
incorrectly
adjusted
in
this way.
it
will produce
a cut
wider than
the
set of the
blade (distance across
the
tips
of the
teeth).
It
would
also tend
to
cause scorch marks
on the
timber
being
cut.
To
Check
(i)
Place
a
square
against
the
fence
as in
Fig.
9
and,
with
the
sawblade just
in
front
of the
fence
in the 90°
crosscut
position
(lock
it in
that position
with
the rip
lock)
check that
the
left
hand face
of the
blade
is
parallel
to the
square.
If it is not
parallel,
adjustment
is
necessary.
To
Adjust
The
illustration
(Fig.
13)
shows
the
components
of the
yoke
assembly.
The
precise alignment
of
rollerhead
(8)
with yoke
(17)
is
made
possible
by
collar
(I)
which
is
fixed
to
the
yoke
by the
locking nuts (J).
(i)
Firstly,
grasp yoke
in
both hands
and
check
it for
movement
left
or
right,
if
there
is
movement tighten
nut
(H)
which increases
the
friction between
the rip
locating slide
bar (K) and
nylon
block
(L).
(ii)
Then,
if the
blade
is
still
not
parallel
to the
square.
release
the
yoke
clamp
(10)
and
loosen
the
lock nuts
(J)
(Fig.
13/13a)
and
turn
yoke slightly
to
left
or
right
until
the
blade
is in
fact parallel
to the
square
and
therefore
also parallel
to the arm
tracks. Then
tighten
all
nuts.
(iii)
Having adjusted
the
blade parallel
to the arm
tracks
in
this
way,
release
the rip
lock
and
pull
the saw
carriage
forward.
Raise
the saw
blade just above
the
surface
of the
table
by
turning
the
elevating handle.
(iv)
Now
release
the rip
locating
slide
bar and the
yoke
clamp
and
then rotate
the
yoke
90° so
that
the
blade
is
facing
the
fence
and
lock
it
into
that
position
with
the
slide
bar and the
yoke clamp. Then push
the saw
carriage
backwards until
the
blade
is
resting against
the
fence.
If
the
blade
is
completely flat, across
its
face against
the
fence,
this
will
confirm
that
the saw
will
perform
accurate
parallel
rip
cutting.
