ELECTRICAL REQUIREMENTS AND SAFETY
mOTOR SAFETY PROTECTION ImPORTANT
To avoid motor damage, the motor should be blown out or vacu-
umed 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 circuit breaker. Using the wrong size fuse
can damage the motor.
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
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

WARNING
• Use only accessories recommended for this
miter saw. Follow instructions that accompany accessories.
Use improper accessories may cause hazards.
• The use of any cutting tool except 10 in. saw blades which meet the
requirements under recommended accessories is prohibited. Do not use accessories such as
shaper cutters or dado sets. This saw is allowed for cutting wood, ferrous material, non-ferrous
material and plastic only. The use of abrasive wheels is prohibited.
• Do not attempt to modify this tool or create accessories not recommended for use with this tool.
Any such alteration or modification is misuse and could result in a hazardous condition leading
to possible serious injury.
ACCESSORIES
Visit your Knova Hardware Department or see the Knova Power and Hand Tool Catalog to
purchase recommended accessories for this power tool.
WARNING
• To avoid the risk of personal injury, do not modify this power tool or use
accessories not recommended by Knova.
• Read warnings and conditions on your CARBIDE TIPPED SAW BLADE. Do not operate the saw
without the proper saw blade guard in place. Carbide is a very hard but brittle material. Care
should be taken while mounting, using, and storing carbide tipped blades to prevent accidental
damage. Slight shocks, such as striking the tip while handling, can seriously damage the blade.
Foreign objects in the workpiece, such as wire or nails, can also cause tips to crack or break off.
Before using, always visually examine the blade and tips for bent blade, cracks, breakage,
missing or loose tips, or other damage. Do not use if damage is suspected. Failure to heed
safety instructions and warnings can result in serious bodily injury.
one 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 and overheating. The table below shows the cor-
rect 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 condi-
tion. 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 #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. Be-
fore 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.
