ELECTRICAL REQUIREMENTS AND SAFETY
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 timelag 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.

the requirements under recommended accessories is prohibited.
Do not use accessories such as shaper cutters or dado sets.
Ferrous metal cutting and 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

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
Make sure this is
connected to a
known ground.

BLADE INFORMATION
• Always use a crosscut blade that is designed for cutting across
grain. NEVER use Rip, Combination, Plywood, Dado or Abrasive
type saw blades at any time
• Always use a 10 in. diameter blade with either a 5/8 in. arbor hole,
speed rating must be at least 4800 RPM.
• Read and understand all instructions provided with each blade
before using on this miter saw.
There are two main materials used for saw blades; high-speed steel
(HSS) and carbide tipped (TCT). While the HSS blades are generally
less expensive than carbide tipped, TCT blades will stay sharper
longer than HSS. As a general rule the more teeth per inch (TPI) the
smoother the cut. Please read the information provided on the blade
for more details for their use.
General Purpose Wood Cutting: 24 - 40 TPI
Fine Woodworking Cutting: 60 - 80 TPI
Non-ferrous Metal Cutting: Use only special blades designed for
cutting this type of material.
Plastic Cutting:
Use only special blades designed for cutting plastic.
NOTE: When cutting non-ferrous or plastic, be sure to clean up
completely after each use. Take special care with metal shavings
after each cut, these can cause damage to the table top.
ALWAYS WEAR EYE PROTECTION.
WARNING
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.
