operation of miter saws, seek guidance from your supervisor, instructor or other qualified person.

ALWAYS hold the work firmly against the fence and table. DO NOT perform any operation free hand

(use clamp wherever possible).

KEEP HANDS out of the path of the saw blade. If

the workpiece you are cutting would cause your

hands to be within 6-3/4 in. of the saw blade, the

workpiece should be clamped in place before

making the cut.

BE SURE the blade is sharp, runs freely and is free

of vibration.

7. ALLOW the motor to come up to full speed before starting a cut.

8. KEEP THE MOTOR AIR SLOTS CLEAN and free of chips or dust.

9. ALWAYS MAKE SURE all handles are tight before cutting, even if the table is positioned in one of the

positive stops.

10. BE SURE both the blade and the collar are clean and the arbor bolt is tightened securely.

11. USE only blade collars specified for your saw.

12. NEVER use blades larger in diameter than 10

inches.

18.

MAKE SURE the blade is not contacting the

workpiece before the switch is turned ON.

19.

IMPORTANT: After completing the cut, release

the trigger and wait for the blade to stop before returning the saw to the raised position.

20.

MAKE 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.

22.

NEVER cut small pieces. If the workpiece being cut

would cause your hand or fingers to be within 6-3/4 in. of the saw blade the workpiece is too small.

23.

PROVIDE adequate support to the sides of the saw

table for long work pieces.

24.

NEVER use the miter saw in an area with flammable

liquids or gases.

25.

NEVER use solvents to clean plastic parts. Solvents

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.

WARNING J

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, 16 A circuit and use a 16 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.

ELECTRICALREQUIREMENTS- cont'd DOUBLEINSULATED[]

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.

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 gauge 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 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.

IA WARNING I

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 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 PROTECTION 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 120 V circuit. 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.

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. Ifthe blade is free,

try to start the saw again. Ifthe 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.

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 era #14 wire with a 15 Atime 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.
