Alignment
of the Blade
"L
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
work-pieces.
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.
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.
1. Use a 3/16"
hex "L" wrench
to loosen
the
four screws in the front
of the column
sup-
port.

Head Screws

2. Raise and lower the radial arm by turning
the handwheel
a few turns in each direction.
It should take about the same amount
of ef-
fort to lower the arm as to raise it.

_
JLWARNINr_:
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.
3. If movement
seems smooth
and the col-
umn does not rock back and forth,
use a
3/16 allen wrench
to retighten
the four
screws in the front
of the column
support.
(Figure
96). Do not over tighten
or it will be
difficult
to raise and lower the radial arm.
After
completing
these steps go on to the
next section,
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 of 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 arm up and down and to get ac-
curate
depth
of cut. If the column
is loose the
blade may "walk" on the workpiece
and stall
the motor,
or cause a bee! in bevel and com-
pound
cuts.

If movement
seems difficult,
loosen
the four
bolts in the back of the column
slightly
(Fig-
ure 97) and go back to step 2, or
