SAFETY INSTRUCTIONS cont.
ELECTRICAL SAFETY
WARNING:
Do not permit fingers to touch the terminals of plug when
!
installing or removing the extension cord from the plug.
1. Double insulated tools are equipped with a polarized plug
(one blade is wider than the other and will require the use of a
polarized extension cord. The Chain Saw's plug will fit into a
polarized extension cord only one way. If the plug does not fit fully into
the extension cord, reverse the plug. If the plug still does not fit, obtain
a correct polarized extension cord. A polarized extension cord will require the use of a polarized
wall outlet. This plug will fit into the polarized wall outlet only one way. If the plug does not fit
fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified
electrician to install the proper outlet. Do not change or alter the equipment plug,
extension cord receptacle, or extension cord plug in any way.
2. Double insulation eliminates the need for the three-wire grounded power cord and
grounded power supply system. Applicable only to Class II (double-insulated) tools.
This Chain Saw is a double insulated tool.
WARNING:
! GFCI (Ground Fault Circuit Interrupter) protection should be
provided on all circuits or outlets to be used for electric chain saws and lawn and
garden power tools. Receptacles are available having built-in GFCI protection and
should be used for this measure of protection.
• Double insulation DOES NOT take the place of normal safety precautions when
operating this tool.
• Guard against electric shock: Prevent body contact with grounded surfaces.
For example: metal pipes, wire fences.
3. BEFORE plugging in the tool, BE SURE that the outlet voltage supplied is within the voltage
marked on the tool's data plate. DO NOT use "AC only" rated tools with a DC power supply.
4. DO NOT expose tools to rain or wet conditions or use electric tools in wet or damp
locations. Water entering an electric tool will increase the risk of electric shock.
5. If operating an electric tool in damp locations is unavoidable, ALWAYS USE a
Ground Fault Circuit Interrupter to supply power to your tool. ALWAYS WEAR
electrician's rubber gloves and footwear in damp conditions.
6. To reduce the risk of electric shock, use only with an extension cord intended for outdoor use,
such as an extension cord of cord type: SW-A, SOW-A, STW-A, STOW-A, SJW-A,
SJOW-A, SJTW-A. or SJTOW-A.
7. INSPECT tool cords for damage. Have damaged tool cords repaired at a Sears Service Center.
BE SURE to stay constantly aware of the cord location and keep it well away
from the cutting blade.
8. DO NOT abuse the extension cord. NEVER use the cord to carry the tool by or to
pull the plug from the outlet. Keep cord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
EXTENSION CORDS
Use a proper extension cord. ONLY use cords listed by Underwriters Laboratories (UL).
Other extension cords can cause a drop in line voltage, resulting in a loss of power
and overheating of tool.
For this tool an AWG (American Wire Gauge) size of a least 18-gauge is recommended
for an extension cord of 25-ft. or less in length. Use 16-gauge for an extension cord
of 50-ft. Use 14-gauge for an extension cord of 100-ft.

SAFETY INSTRUCTIONS cont.
EXTENSION CORDS cont.
Remember, a smaller wire gauge size has greater capacity than a larger number
(14-gauge wire has more capacity than 16-gauge wire; 12-gauge wire has
more capacity than 14-gauge). When in doubt use the smaller number.
Minimum guage for extension cords
CAUTION:
! Keep the extension cord clear of the work area. Position the cord so that it will
not get caught on bushes, hedges, tree trunks, lawnmowers or other obstructions while you are
working with the Chain Saw.
WARNING:
! Check extension cords before each use. If damaged replace immediately.
Never use tool with a damaged cord since touching the damaged area could cause electrical
shock, resulting in serious injury.
