ELECTRICAL REQUIREMENTS AND SAFETY

ELECTRICAL REQUIREMENTS – 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 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 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. 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
