"READ ALL INSTRUCTIONS" -- Failure to follow the SAFETY RULES identified by BULLET (I) symbol
listed BELOW and other safety precautions, may result in serious personal injury.
Cut only one workpiece
at a time. Multiple workpieces
cannot be adequately clamped or braced and may bind
on the blade or shift during cutting.
Be certain the miter saw is mounted
or placed on a
level, firm work surface before using.
A level and firm
work surface reduces the risk of the miter saw becoming
unstable.
Plan
your
work.
Provide
adequate
support
accessories
such
as tables,
saw
horses,
table
extension, etc. for workpieces
wider
or longer than
the table top (see page 21).
Workpieces
longer or
wider than the miter saw table can tip if not securely
supported.
If the cutoff piece or workpiece tips it can lift
the lower guard or be thrown by the spinning blade.
Do not use another person as a substitute
for a table
extension
or as additional
support.
Unstable support
for the workpiece
can cause the blade to bind or the
workpiece
to shift during the cutting operation
pulling
you and the helper into the spinning blade.
The cutoff
piece
must
not be jammed
against
or
pressured
by any other means against the spinning
saw blade.
If confined, i.e. using length stops, it could
get wedged against the blade and thrown violently.
Always use a clamp or a fixture designed
to properly
support
round
material
such
as dowel
rods,
or
tubing.
Rods have a tendency to roll while being cut,
causing the blade to "bite" and pull the work with your
hand into the blade.
When cutting
irregularly
shaped
workpieces,
plan
your work so it will not slip and pinch the blade and
be torn from
your
hand.
A piece of molding,
for
example, must lie flat or be held by a fixture or jig that will
not let it twist, rock or slip while being cut.
,
Let the blade reach full speed before contacting
the
workpiece.
This will help avoid thrown workpieces.
if the workpiece
or blade
becomes
jammed
or
bogged
down,
turn miter
saw "OFF"
by releasing
switch.
Wait for all moving parts to stop and unplug
the miter
saw,
then
work
to free
the jammed
material.
Continued
sawing with jammed
workpiece
could cause loss of control or damage to compound
miter saw.
Braking
action
of the saw causes
the saw head to
jerk downward.
Be ready
for this
reaction
when
making an incomplete cut or when releasing the switch
before the head is completely in the down position.
After finishing
the cut, release the switch,
hold the
saw arm down
and wait
for blade
to stop before
removing work or cutoff piece.
If blade does not stop
within five (5) seconds, unplug the saw and follow the
instructions
in the
Troubleshooting
section.
REACHING WITH YOUR HAND UNDER A COASTING
BLADE IS DANGEROUS!

Some
dust
created
by power
sanding,
sawing,
grinding,
drilling,
and
other
construction
activities
contains
chemicals
known
to
cause cancer, birth defects
or other reproductive
harm.
Some examples
of these chemicals
are:
• Lead from lead-based
paints,
Crystalline
silica from bricks and cement and other
masonry products, and
Arsenic
and chromium
from chemically
treated
lumber.
Your risk from these exposures varies, depending
on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated
area, and work
with approved safety equipment,
such as those dust masks
that
are specially
designed
to filter
out microscopic
particles.
There are additional
safety instructions
for particular
operations
of the saw in the operating
section.
Read
the rest of the manual for safe operation.
