MOTOR SAFETY PROTECTION IMPORTANT
To avoid motor damage, the motor should be blown out or vacu-
umed frequently to keep sawdust from interfering with the motor
ventilation.
1.
CONNECT
this saw to a 120 V, 15 A circuit with a 15 A
time-delay fuse or circuit breaker. Using the wrong size fuse
can damage the motor.
2. If the motor will not start, release the trigger switch
immediately.
UNPLUG THE SAW
. Check the saw blade to
make sure it turns freely. If the blade is free, try to start
the saw again. If the motor still does not start, refer to the
TROUBLESHOOTING GUIDE
.
3. If the tool suddenly stalls while cutting wood, release the
trigger switch, unplug the tool and free the blade from the
wood. The saw may now be started and the cut finished.
CAUTION
In all cases make certain the receptacle in
question is properly grounded. If you are not sure, have
a certified electrician check the receptacle
.
POWER SUPPLY AND MOTOR SPECIFICATIONS
The AC motor used in this saw is a universal, nonreversible
type. See “MOTOR” in the “PRODUCT SPECIFICATIONS”
section on page 1.
WARNING
To avoid electrical hazards, fire
hazards, or damage to the tool, use proper circuit
protection. Your saw is wired at the factory for 120 V
operation. Connect to a 120 V, 15 A circuit and
use a 15 A time delay fuse or circuit breaker. To
avoid shock or fire, if power cord is worn or cut, or
damaged in any way, have it replaced immediately
.
ELECTRICAL REQUIREMENTS – DOUBLE INSULATED
The power tool is double insulated to provide a double
thickness of insulation between you and tool’s electrical
system. All exposed metal parts are isolated from the
internal metal motor components with protecting insulation.
Replacement parts
– When servicing, use only identical
replacement parts.
Polarized plugs
– This saw has a plug that looks like
the one shown below:
To reduce the risk of electrical shock, this saw
has 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 outlet, reverse the plug. If it still does
not fit, contact a qualified electrician
to install the proper outlet. Do not
change the plug in any way.
WARNING
Double insulation does not take
the place of normal safety precautions when
operating this tool
.
To avoid electrocution:
1. Use only identical replacement parts when servicing a too
with double insulation. Servicing should be performed by
a qualified technician.
2. Do not use power tools in wet or damp locations or expose
them to rain or snow.
4.
FUSES
may “blow” or circuit breakers may trip frequently if:
a.
MOTOR
is overloaded – overloading can occur if you feed
too rapidly or make too many start/stops in a short time.
b.
LINE VOLTAGE
is more than 10% above or below the
nameplate voltage rating. For heavy loads, the voltage at
motor terminals must equal the voltage specified on the
nameplate.
c.
IMPROPER
or dull saw blades are used.
5. Most motor troubles may be traced to loose or incorrect
connections, overload, low voltage or inadequate power
supply wiring. Always check the connections, the load and
supply circuit if the motor doesn’t run well. Check minimum
auge for the length of cord you are using on the chart below.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord.
Make sure your extension cord is
in good condition. When using an extension cord, be sure to use
one heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage, resulting in
loss of power and overheating. The table below shows the cor-
rect size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
Be sure your extension cord is properly wired
and in good
condition. Always replace a damaged extension cord or have
it repaired by a qualified person before using it. Protect your
extension cords from sharp objects, excessive heat and damp
or wet areas.
Use a separate electrical circuit for your tools.
This circuit
must not be less than a #12 wire with a 20 A time lag fuse or a
#14 wire with a 15 A time lag fuse.
NOTE
: When using an extension cord on a circuit with a #14
wire, the extension cord must not exceed 25 feet in length.
Before connecting the tool to the power line, make sure the
switch is in the OFF position and the electric current is rated
the same as the current stamped on the motor nameplate,
running at a lower voltage will damage the motor.
