ELECTRICAL REQUIREMENTS - cont'd

DOUBLE INSULATED []

The power tool is double insulated to provide a double thickness of insulation between you and tool'selectrical 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.

[A 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 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, 15 A circuit with a 15 A time-delay fuse or circdt breaker. Using the wrong size fuse can damage the motor.

2.If the motor won'tstart, 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.

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 hea W enough to carp/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 a #I 2 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.
