Electrical Requirements And Safety - KNOVA KN CS-3555R Manual

CHOP SAW SAFETY
• This chop saw has been designed for cutting metals
using reinforced abrasive chop saw wheels only. Do not
remove the wheel, install a steel blade and attempt to
cut other types of materials such as wood, masonry,
etc. Attempting to cut these other types of materials
could cause an accident resulting in serious personal
injury.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS
The AC motor used in this saw is a universal, nonreversible
type. See "MOTOR" in the "PRODUCT SPECIFICATIONS"
section on page 1.
WARNING
To avoid electrical hazards, fire hazards, or damage to
the tool, use proper circuit protection. Your saw is wired
at the factory for 120 V operation. Connect to a 120 V,
15 A circuit and use a 15 A time delay fuse or circuit
breaker. To avoid shock or fire, if power cord is worn or
cut, or damaged in any way, have it replaced
immediately.
ELECTRICAL REQUIREMENTS – cont'd
DOUBLE INSULATED
The power tool is double insulated to provide a double thick-
ness of insulation between you and tool's electrical system.
All exposed metal parts are isolated from the internal metal
motor components with protecting insulation.
Replacement parts – When servicing, use only identical
replacement parts.
Polarized plugs – This saw has a plug that looks like the one
shown below:
To reduce the risk of electrical
shock, this saw has a polarized plug
(one blade is wider than the other).
This plug will fit in a polarized outlet
only one way. If the plug does not
fit fully in the outlet, reverse
the plug. If it still does not fit,
contact a qualified electrician to install
the proper outlet. Do not change the
plug in any way.
WARNING
Double insulation does not take the place
of normal safety precautions when operating this
tool.
To avoid electrocution:
1. Use only identical replacement parts when servicing a
too with double insulation. Servicing should be performed
by a qualified technician.
2. Do not use power tools in wet or damp locations or
expose them to rain or snow.
• 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 serious personal injury.
MOTOR SAFETY PROTECTION IMPORTANT
To avoid motor damage, the motor should be blown out or
vacuumed 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. 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.
4. 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 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 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.
Be sure your extension cord is properly wired and in good
condition. 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.
