19.IMPORTANT: After completing the cut, release the
trigger and wait for the blade to stop before returning
the saw to the raised position.
20MAKE SURE the blade has come to a complete stop
before removing or securing the workpiece, changing
the workpiece angle, or changing the angle of the
blade.
21 .NEVER cut metals or masonry products with this
tool. This miter saw is designed for use on wood and
wood-like products.
22NEVER cut small pieces. If the workpiece being cut
would cause your hand or fingers to be within 6-3/4
inches of the saw blade the workpiece is too small
2&PROVIDE adequate support to the sides of the saw
table for long work pieces.
5. KEEP BANDS out of the path of the saw blade. If
the workpiece you are cutting would cause your
hands to be within 6-3/4 inches of the saw blade, the
workpiece should be clamped in place before making
the cuL
6. BE SURE the blade is sharp runs freely and is free of
vibration.
7. ALLOW the motor to come up to ful! speed before
starting a cut.
8. KEEP THE MOTOR AIR SLOTS OLEAN and free of
chips or dust.
9. ALWAYS MAKE SURE all handles are tight before

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 2.
[A WARNING]
To avoid electrical hazards, fire hazards, or damage to
the too!, use proper circuit protection. Your saw is wired
at the factory for 120V operation. Connect to a 120V,
15 Amp circuit and use a 15 amp. 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 REQUREMENTS - cont'd
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 wilt fit in a polarized outlet only one way. If the ptug
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.
la,WARNINGn
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 toot 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.
MOTOR SAFETY PROTECTmON
iMPORTANT:
To avoid motor damage, the motor should be blown out
or vacuumed frequently to keep sawdust from interfering
with the motor ventilation.
1. CONNECT this saw to a 120V, 15 amp. circuit with a
15 amp. time delay fuse or circuit breaker. Using the
wrong size fuse can damage the motor.
2. If the motor won't 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 too! suddenly statls 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
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 duJl 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 gauge for the
length of cord you are using on the chart below.
GUmDEUNES FOR EXTENSmON CORDS
Use a proper e×tenaion 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 cause overheating. The table below shows
the correct 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 # 12 wire and should
be protected with a 15 Amp time delay fuse. 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.
