THE
VARIOUS
OPERATING
ADJUSTMENTS
OF
BASIC
MACHINE
The
numbers

10.1
Arm
Rotation
refer
to
those
in the
''Controls"
illustrations
on
page
2
The
radial
arm
rotates
to
right
or
left
for
mitre cuts.
Release
the
mitre clamp handle (18)
and the
mitre latch
(19).
Then swing
the arm (2)
right
or
left
to the
required
angle. Then lock
the
clamp
handle(18).
The
calibrated mitre scale
(1)
is
just below
the
elevating
handle
and
indicates
the
angle
of the arm
relative
to the
'0'
straight cross-cut position.
The
mitre latch
(15)
is
only used
to
locate
the arm in the
0° and 45°
positions
but
adopt
the
habit
of
using
the
mitre
clamp handle also
to
secure
the arm in
this,
as
well
as any
other,
position.

Blade
Height
The
Radial Arm,
and
hence also
the Saw
blade,
can be
raised
or
lowered
by
turning
the
elevating
handle
(6)
top
of the
column. Each complete rotation
of the
handle
moves
the
blade
up or
down
by
about 3mm.
10.3 Yoke
Assembly
Rotation
Changing from cross-cut
to the rip
position takes
only
seconds.
Release
the rip
slide
bar (4) and the
yoke clamp (10)
and
then
swing
the
yoke
to
right
or
left.
The
yoke locks
automatically
at the
four
90°
positions,
but
remember
to
always secure
the
yoke clamp also
to
maximise accuracy.
10.4
Blade
Tilting
Turn
the
elevating handle
to
raise
the
sawblade
well
above
the
table. Release bevel clamp (12)
and
bevel
latch
(1'
Tilt
the
motor
to the
desired
angle
on the
bevel
scale.
With
clamp released,
the
latch will automatically locate
in the
popular
0°. 45° and 90°
angle positions.

MAKING
THE
BASIC
CUTS

Cross
Cut

Set
the
radial
arm at
right angles
to the
fence.
registered
as 0° on the
mitre scale beneath
the
elevating
handle.
Lock
the
mitre
latch
in
position
and
tighten
the arm
clamp handle.
Turn
the
elevating handle
to
lower
the
blade
into
position
behind
the
fence
in its
correct
position
for
the
thickness
of the
material being
cut
(See Fig.
25)
To
cut
right through
the
material
to be
sawn
it is
necessary
to cut a
shallow groove
or
kerf
also
in the
table top.
If
such
a
groove
is not
already
there,
switch
on
the
motor before
the
blade actually
touches
the
table surface
so
that
it
will
cut
into
the
table
slightly
when lowering continues. Switch
off the
motor.
Place
material
on
worktable
and
hold
firmly
against
the
fence, keeping your thumb
and
fingers
well
away
from
the
path
the
sawblade will take.
Switch
on
motor
and
draw
the
sawblade
through
the
fence
and
across
the
material
to
make
the
cut.
You
will
find that
you do not
need
to
pull
the
motor
assembly forward
-
rather
you
will need
to
limit
the
speed
of
travel
in the cut
otherwise
the
blade
will
tend
to
jam.
After
completing
the
cut, switch
off and
carefully
return
the
sawblade
to its
rest position
behind
the
fence.
