Double insulation
electric power tools which eliminates the need
for the three wire grounded power cord and
grounded power supply system. It is a recog-
nized and approved system by Underwriter's
Laboratories, CSA and Federal OSHA authorities.
IMPORTANT: Servicing of a tool with double in-
sulation requires care and knowledge of the sys-
tem and should be performed only by a qualified
service technician.
WHEN SERVICING, USE ONLY IDENTICAL RE-
PLACEMENT PARTS.
POLARIZED PLUGS. To reduce the risk of elec-
trical shock, your tool is equipped with a polar-
ized plug (one blade is wider than the other), this
plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified
electrician to install the proper outlet. To reduce
the risk of electrical shock, do not change the
plug in any way.
Extension Cords
Replace damaged cords immediately. Use of
damaged cords can shock, burn or electrocute.
Connect this saw to a 120V, 15-amp branch cir-
cuit with a 15-amp fuse or circuit breaker. Using the
wrong size fuse can damage the motor.
Fuses may "blow" or circuit breakers may trip fre-
quently if motor is overloaded. Overloading can
occur if you feed the blade into the workpiece too
rapidly or start and stop too often in a short time.
Most motor troubles may be traced to loose or in-
correct connections, overload or low voltage (such
as small size wire in the supply circuit or overly long
supply circuit wire). Always check the connections,
the load and the supply circuit whenever motor
does not work well.

Electric Brake

Your saw is equipped with an automatic electric
brake which is designed to stop the blade from spin-
ning in about five (5) seconds after you release the
trigger switch. It is useful when making certain cuts
in wood where a coasting blade would result in a
wide, imprecise cut.

SAVE THESE INSTRUCTIONS
If an extension cord is necessary, a cord with ad-
equate size conductors should be used to prevent
excessive voltage drop, loss of power or overheat-
ing. The table shows the correct size to use, de-
pending on cord length and nameplate amperage
rating of tool. If in doubt, use the next heavier
gauge. Always use U.L. and CSA listed extension
cords.

other causes, the motor will gradually slow
down and the braking action is initiated ONLY
by the release of the trigger switch.
The electric blade brake of your miter saw has been
designed for highest degree of reliability, but unex-
pected circumstances such as contamination on the
commutator and brushes or failure of motor's com-
ponents can cause the brake not to activate. If this
condition occurs, turn the saw "ON" and "OFF" four
to five times without contacting the workpiece. If
the tool operates but the brake does not consis-
tently stop the blade in about five seconds, DO NOT
use saw and have it serviced immediately.
The brake action of this
saw is not intended as a
safety feature. Remember to let the saw blade
come to a complete stop before raising the
blade from the workpiece. As always, the guard
system is your best protection against uninten-
tional contact with a spinning saw blade.
NEVER wedge open or defeat the closing action
of the lower guard.
