Lower guard should
be retracted
manually
only for special cuts such as "Pocket
Cuts"
and "Compound
Cuts",
Raise lower guard
by Lower Guard Lift Lever, As soon as blade
enters
the material,
lower
guard
must
be
released. For all other sawing, the lower guard
should operate automatically.
Always
observe
that
the lower
guard
is
covering
the blade before placing
saw down
on bench
or floor.
An unprotected,
coasting
blade will cause the saw to walk backwards,
cutting whatever
is in its path. Be aware of the
time it takes for the blade to stop after switch is
released.
NEVER hold piece being cut in your
hands
or across
your
leg. It is important
to support
the work properly
to minimize
body exposure,
blade binding, or loss of control.
Hold tool by the insulated
gripping
surfaces
when
performing
an operation
where
the
cutting
tool may contact
hidden
wiring
or it
own cord.
Contact with a "live" wire will also
make exposed metal parts of the tool "live" and
shock the operator.
fail in the "OFF" position, the saw may not
start. If it should fail while
the saw is
running, the saw may not shut off. If either
occurs, unplug the saw immediately and do not
use until repaired.
This circular saw should not be mounted to
a table and converted to a table saw. Circular
saws are not designed or intended to be used
as table saws.
CAUSES AND OPERATOR
PREVENTION
OF KICKBACK:
Kickback
is a sudden reaction to a pinched,
bound or miealigned saw blade, causing an
uncontrolled saw
to lift up and out of the
workpiece toward the operator.
When
ripping
always
use a rip fence
or
straight edge guide.
This improves
accuracy
of cut and reduces the chance for blade binding.
Always
use blades
with
correct
size and
shape
(diamond
vs. round)
arbor
holes.
Blades
that
do not match
the
mounting
hardware
of the saw will run eccentrically,
causing loss of control and will not allow proper
vari-torque engagement.
Never
use
damaged
or incorrect
blade
washers
or bolts. The blade washers and bolt
were
specially
designed
for your
saw,
for
optimum performance
and safety of operation.
The blade washers and the bolt on your saw
have
been
designed
to work as a "VARI-
TORQUE CLUTCH';
Understand
the operation
and settings of the VARI- TORQUE
CLUTCH
because the proper settingof the CLUTCH,
combined
with firm handling of the saw
will
allowyou tocontrol K ICKBACK
Do not run the saw while carrying it at your
side. Lower
guard may
be opened
by a
contact
with your clothing.
Accidental
contact
with the spinning
saw blade
could result
in
serious personal injury.
Depending
upon
use, the switch
may
not
last the life of the saw. If the switch
should
VARI-TORQUE
CLUTCH
When the blade is pinched
or bound tightly by
the kerr closing down, the blade stalls and the
motor
reaction
drives
the unit rapidly
back
toward the operator.
If the blade becomes
twisted or misa//gned
in
the cut, the teeth at the back edge of the blade
can dig into the top surface of the wood causing
the blade to climb out of the kerr andjump
back
toward the operator.
Kickback
is the result
of tool misuse
and/or
incorrect
operating
procedures
or conditions
and
can
be
avoided
by
taking
proper
precautions
as given below:
Maintain
a firm grip with both
hands on the
saw
and position
your
body
and arm to
allow
you
to resist
KICKBACK
forces.
