POWER TOOL SAFETY
GENERAL SAFETY INSTRUCTIONS
BEFORE USING THIS POWER TOOL
Safety is a combination of common sense,
staying alert and knowing how to use your power
tool.
To avoid mistakes that could cause serious
injury, do not plug the tool in until you have
read and understood the following.
1. READ and become familiar with the
entire Operator’s Manual. LEARN
the tool’s application, limitations and
possible hazards.
2. KEEP GUARDS IN PLACE and in working
order.
3. REMOVE ADJUSTING KEYS AND
WRENCHES. Form the habit of checking to
see that keys and adjusting wrenches are
removed from the tool before turning ON.
4. KEEP WORK AREA CLEAN. Cluttered areas
and benches invite accidents.
5. DO NOT USE IN DANGEROUS
ENVIRONMENTS. Do not use power tools
in damp locations, or expose them to rain or
snow. Keep work area well lit.
6. KEEP CHILDREN AWAY. All visitors and
bystanders should be kept a safe distance
from work area.
7. MAKE WORKSHOP CHILD PROOF with
padlocks, master switches or by removing
starter keys.
8. DO NOT FORCE THE TOOL. It will do the job
better and safer at the rate for which it was
designed.
9. USE THE RIGHT TOOL. Do not force the tool
or an attachment to do a job for which it was
not designed.
10.USE PROPER EXTENSION CORDS. 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
result in a drop in line voltage and in loss of
power which will cause the tool to overheat.
The table on page 7 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.
11.WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets or other jewelry which may get
caught in moving parts. Nonslip footwear is
recommended. Wear protective hair covering
to contain long hair.
12.ALWAYS WEAR EYE PROTECTION. Any
power tool can throw foreign objects
into the eyes and could cause
permanent eye damage. ALWAYS
wear Safety Goggles (not glasses)
that comply with ANSI Safety standard Z87.1.
Everyday eyeglasses have only impact–
resistant lenses. They ARE NOT safety
glasses. Safety Goggles are available at
Sears. NOTE: Glasses or goggles not in
compliance with ANSI Z87.1 could seriously
injure you when they break.
13.WEAR A FACE MASK OR DUST MASK.
Sawing operation produces dust.
14.SECURE WORK. Use clamps or a vise to
hold work when practical. It is safer
than using your hand and it frees
both hands to operate the tool.

3. IF YOU ARE NOT thoroughly familiar with
the operation of miter saws, seek guidance
from your supervisor, instructor or other
qualified person.
4. ALWAYS hold the work firmly against the
fence and table. DO NOT perform any
operation free hand (use clamp wherever
possible).
5. 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.
6. 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.
13. NEVER apply lubricants to the blade when it
is running.
14. ALWAYS check the blade for cracks or
damage before operation. Replace a cracked
or damaged blade immediately.
15. NEVER use blades recommended for
operation at less than 4800 RPM.
16. ALWAYS keep the blade guards in place
and use at all times.

ELECTRICAL REQUIREMENTS
WARNING
!
ELECTRICAL REQUIREMENTS AND SAFETY
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR
BREAKDOWN, grounding provides a path of
least resistance for electric currents and reduces
the risk of electric shock. This tool is equipped
with an electrical cord that has an equipmentgrounding conductor and a grounding plug. The
plug must be plugged into a matching receptacle
that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit the receptacle, have the proper
receptacle installed by a qualified electrician.
IMPROPER CONNECTION of the equipment
grounding conductor can result in risk of electric
shock. The conductor with the green insulation
(with or without yellow stripes) is the equipment
grounding conductor. If repair or replacement of
the electrical cord or plug is necessary, do not
connect the equipment grounding conductor to a
live terminal.
CHECK with a qualified electrician or service
person if you do not completely understand the
grounding instructions, or if you are not certain
the tool is properly grounded.
USE only three-wire extension cords that have
three-pronged grounding plugs with three-pole
receptacles that accept the tool’s plug. Repair or
replace damaged or worn cords immediately.
GUIDELINES FOR EXTENSION
CORDS
USE THE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition.
Use an extension cord 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, overheating and burning out
of the motor. The table on the right 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.
Make sure your extension cord is properly
wired and in good condition. Always replace a
damaged extension cord or have it repaired by a
qualified technician before using it. Protect your
extension cords from sharp objects, excessive
heat and damp or wet areas.
Use a separate electrical circuit for your tool. This
circuit must not be less than #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. Before connecting
the motor 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. This tool is intended for
use on a circuit that has a receptacle like the one
illustrated in Fig. 1.
Fig. 1 shows a three-pronged electrical plug and
receptacle that has a grounding conductor. If a
properly grounded receptacle is not available,
an adapter (Fig. 2) can be used to temporarily
connect this plug to a two-contact grounded
receptacle. The adapter (Fig. 2) has a rigid lug
extending from it that MUST be connected to
a permanent earth ground, such as a properly
grounded receptacle box.
In all cases, make certain the receptacle is
properly grounded. If you are not sure, have a
qualified electrician check the receptacle.
This tool is for indoor use only. Do not
expose to rain or use in damp locations.
