Alignment
of the Blade
ALIGNMENT
OF THE
BLADE
IS THE
MOST
IMPORTANT
STEP
IN
ASSEMBLING
YOUR
RADIAL
ARM
SAW.
The blade of your radial arm saw must be
aligned
properly
for two reasons:
to make
cuts accurate,
and to prevent
binding
of the
blade and workpiece
which can cause jams or
thrown workpieces.
These
adjustments
must be done in order,
before using your saw for the first time.
If
they are not done
in order
the saw will not
cut accurately.
If you miss an adjustment,
you
must go back to the adjustment
you missed
and repeat
all steps from that point on.
1. Use a 3/16 hex
"'L'" wrench
to loosen
the
four screws
in the front
of the column
support.

,
Head Screws
These adjustments
are like fine tuning a
piece of equipment.
Often a series of steps
must be repeated
more than once in order to
get the adjustment
just right.
,WARNING:
Plugging
the saw in
during
alignment
can result
in electrical
shock
or your
fingers,
hand,
or arm
being
cut off from
blade
contact.
Do not
plug in the saw at any time during
align-
ment.
The saw should
only be plugged
in when
it is to be used.

2. Raise and lower the radial arm by turning
the handwhee!
a few turns in each direction.
tt should
take about the same amount
of ef-
fort to lower the arm as to raise it.
3. If movement
seems
smooth
and the
column
does
not rock
back
and forth,
go to
the next
section,
or
If movement
seems difficult,
loosen
the four
bolts in the back of the column
slightly
(Figure
36) and go back to step 2, or
Make sure that the blade and blade guard are
removed
from the arbor
shaft before
begin-
ning to align your saw. Do not install the
blade or blade guard until you are instructed
to do so.
Adjusting
Elevation
The goal
or" this adjustment
is to make
up-
ward
and
downward
movement
of the radial
arm smooth
and
firm.
If the column
that
sup-
ports
the arm is too tight
it will be difficult
to
move
the ar_
up and
down
and to get ac-
curate
deplh
of cut.
If the column
is loose
the
blade
may "walk"
on the workpiece
and stall
the motor,
or cause
a heel
in bevel
and com-
pound
cuts.
If column
rocks back and forth, tighten
the
four bolts in the back of the column
slightly
(Figure
36) and go back to step 2.
