ELECTRICAL SAFETY
GENERAL ELECTRICAL CONNECTIONS
DANGER: To reduce the risk of electrocution:
1. Use only identical replacement parts when servicing. Servicing should be
performed by a qualified service technician.
2. Do not use in rain or where floor is wet. This tool is intended for indoor use only.
110-120-Volt, 60 Hz. Tool Information
The plug supplied on your tool may not fit into the outlet you are planning to use."Yourlocal
electrical code may require slightly different power cord plug connections. If these
differences exist refer to and make the proper adjustments per your local code before your
tool is plugged in and turned on.
In the event of a malfunction or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock. This tool is equipped with an electric
cord having an equipment-grounding conductor and a grounding plug, as shown in
Figure A. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Do not modify the plug provided. If it will notfit the outlet, have the proper outlet installed
by a qualified electrician.
A temporary adapter may be used to connect this plug to a 2-prong outlet (as shown in
Figure A), if a properly grounded 3-prong outlet is not available. This temporary adapter
should be used only until a properly grounded 3-prong outlet can be installed by a qualified
electrician. The green colored rigidear, lug or the like, extending from the adapter must be
connected to a permanent ground, such as aproperly grounded outlet box.
Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-grounding conductor to a live
terminal.
WARNING: : Do not permit fingers to touch the terminals of plug when
installing or removing the plug to or from the outlet.
If the grounding instructions are not completely understood, or if you are in doubt as to
whether the tool is properly grounded, check with a qualified electrician or service
personnel.
WARNING: :If not properly grounded, this tool can cause an electrical
shock, particularly when used in damp locations, in proximity to plumbing, or out
of doors. If an electrical shock occurs there is the potential of a secondary
hazard, such as your hands contacting the saw blade.

1. If operating the power 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.
2. DO NOT expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
3. ALWAYS periodically inspect tool cords and extension cords for damage. Have
damaged cords repaired at a Sears Service Center. BE SURE to stay constantly aware
of the cord location and keep itwell away from the moving blade.
4. ALWAYS use the proper extension cord and MAKE SURE the cord is in good
condition. ONLY USE a cord that is heavy enough to carry the current your tool
will draw. An undersized cord will cause a current drop in line voltage resulting in a loss
of power and overheating. A wire gauge size AWG (American Wire Gauge) of at least
14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the
next heavier size. Smaller gauge wires, have greater capacity (14 gauge wire has more
capacity than 16 gauge wire).
5. DO NOT abuse the cord. NEVER use the cord 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.
6. When operating a power tool outside, ALWAYS use an outdoor extension cord marked
"W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric
shock.

7. ALWAYS be sure that the blade clears the workpiece. NEVER start the saw with
the blade touching the workpiece. ALWAYS allow the motor to come up to full speed
BEFORE starting a cut.
8. ALWAYS support long workpieces when cutting to minimize the risk of the
blade pinching or kickback. The saw may slip, walk or slide while cutting long or
heavy boards.
9. NEVER use a length stop on the free (scrap end) of a clamped workpiece.
NEVER hold onto or bind the free scrap end of the workpiece in any operation. If a work
clamp and length stop are used together, THEY MUST BOTH BE INSTALLED on the
same side of the saw table to prevent the saw from catching the loose end and
kicking up.
10. NEVER cut more than one piece at atime. DO NOT STACK more than one
workpiece on the saw table at atime.
11. ALWAYS avoid awkward operations and hand positions where a sudden slip
could cause your hand to move into the blade. ALWAYS make sure that you have
good balance. NEVER operate your saw on the floor or in a crouched position.
12. NEVER stand or have any part of your body in line with the path of the blade.
13. ALWAYS only use the correct blades. Use the right blade size, style and cutting
speed for the material and the type of cut. DO NOT use blades with incorrect size
holes. NEVER use blade washers or blade bolts that are defective or incorrect.
The maximum blade capacity for this saw is 10 inches.
14. ALWAYS keep blades clean, sharp and with the sufficient set. Sharp blades
minimize stallingand kickback.
15. DO NOT use dull or damaged blades. Bent blades can break easily, or cause kickback.
16. DO NOT remove the saw's blade guards. NEVER operate the saw with any guard or
cover removed. MAKE SURE that all guards are operating properly BEFORE each use.
