USE THE RIGHT TOOL. Don't force tool or the
attachment to do a job for which it was not designed.
10. USE 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 willdraw.An undersized
cord will cause a drop in line voltage resulting in loss
of power and overheating.The table on page 5 shows
the correctsize to use depending on co'rdlengthand
nameplate ampere rating. If in doubt, use the next
heavier gauge. The smaller the gauge number, the
heavier the cord.

SAVE THESE INSTRUCTIONS

DOUBLE INSULATED []
The miter saw is double insulated to provide a double
thickness of insulation between you and the 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 caw 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.
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 tool with double insulation.
Servicing shouldbe performedby a qualified
technician.
2, Do not use power toolsin wet or damp areas or
expose them to rain.
This tool is intended for indoor use only.
MOTOR SAFETY PROTECTION
IMPORTANT:
To avoid motor damage, the motor should be blown OL_
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 circuitbreaker. Using the
wrong size fuse can damage the motor.
2. IF the motorwon't start, release the triggerswitch
immediately.UNPLUG THE SAW. Check the saw
blade to make sure itturns freely. Ifthe blade is free,
try to startthe saw again, if the motor stilldoes not
start, refer to the "TROUBLESHOOTING CHART".
3. IF the saw suddenly stalls while cuttingwood, release
the tdgger switch, unplugthe tool, and free the blade
from the wood. The saw may now be restarted and
the cutfinished.
4. FUSES may "blow" or circuitbreakers may trip
frequenUy if:
a. MOTOR isoverloaded - overloading can occur if
you feed too rapidlyor make too many start/stops
in a short time.
b. LINEVOLTAGE is more than 10% above or below
the nameplate voltage rating.For heavy loads,
however,the voltage at motorterminals mustequal
the voltage specified on the name plate.
c. IMPROPER or dull saw blades are used.
5. Most motortroublesmay be traced to k_oseor incorrect
connections, overload, low voltage or inadequate
power supply wiring.Always check the connections,
the load and the supply circuitifthe motordoesn't run
well.Check wire sizes and length with the Extension
Cord Chart below.
GUIDELINES FOR EXTENSION CORDS
USE 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 productwilldraw. An undersized cord will
cause a drop in line voltage, resultingin loss of power and
cause overheating,The table below shows the correctsize
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 extensioncord
or have it repaired by a qualified person before using it.
Protect yourextension 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 motorto 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.
