"READ ALL INSTRUCTIONS" — Failure to follow the SAFETY RULES identified by BULLET (
WARNING

ed BELOW and other safety precautions, may result in serious personal injury.
Double Insulated Tools
Double insulation is a design concept used in
electric power tools which eliminates the need for the
three wire grounded power cord and grounded power
supply system. It is a recognized and approved sys-
tem by Underwriter's Laboratories, CSA and Federal
OSHA authorities.
Servicing of a tool with double insulation requires
G
care and knowledge of the system and should be
performed only by a qualified service technician.
WHEN SERVICING, USE ONLY IDENTICAL
G
REPLACEMENT PARTS.
POLARIZED PLUGS. Your tool is equipped with
G
a polarized 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 out-
let, 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.
"SAVE THESE INSTRUCTIONS"

Electrical Requirements

1. Connect this saw to a 120V, 15-amp branch cicuit
with a 15-amp time delay fuse or circuit breaker.
Using the wrong size fuse can damage the motor.
2. Fuses may "blow" or circuit breakers may trip
frequently 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.
3. Most motor troubles may be traced to loose or
incorrect connections, overload, low voltage
(such as small size wire in the supply circuit or too
overly long supply circuit wire). Always check the
connections, the load and the supply circuit when-
ever motor does not work well.

Electric Brake

Your saw is equipped with an automatic electric brake
which is designed to stop the blade from spinning 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, impre-
cise cut.

Safety
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 compo-
nents can cause the brake not to activate. If this con-
dition occurs, turn the saw "ON" and "OFF" four to five
times without contacting the workpiece. If the tool
operates but the brake does not consistently stop the
blade in about five (5) seconds, DO NOT use saw and
have it serviced immediately.
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 unintentional contact with a spinning saw
blade. NEVER wedge open or defeat the closing
action of the lower guard.

Extension Cords
Replace damaged cords immediately. Use of
G
damaged cords can shock, burn or electrocute.
If an extension cord is necessary, a cord with
G
adequate size conductors should be used to pre-
vent excessive voltage drop, loss of power or
overheating. The table shows the correct size to
use, depending 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.
