Important Safety Instructions
_ WARNING: Read all instructions before operating
product. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury.
SAVE THESE INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate
layers of electrical insulation or one single layer of reinforced insulation
between you and the tool's electrical system. Tools built with this
insulation system are not intended to be grounded. As a result, your
tool is equipped with a two prong plug which permits you to use
extension cords without concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety
precautions when operating this tool. The secondary insulation
system is for protection against injury resulting from a possible failure
of the primary insulation within the tool.
_CAUTION: WHEN SERVICING USE ONLY IDENTICAL
REPLACEMENT PARTS. Repair or replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided, this
plug will fit in the 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.
• KEEP GUARDS IN PLACE and in working order.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit
of checking to see that keys and adjusting wrenches are removed
from tool before turning it on.
• KEEP WORKAREA CLEAN. Cluttered areas and benches invite
injuries.
• DON'T USE IN DANGEROUS ENVIRONMENT. Don't use
power tools in damp or wet locations, or expose them to rain.
Keep work area well lighted.
• KEEP CHILDREN AWAY. All visitors should be kept at a safe
distance from work area.
• MAKE WORKSHOP KID PROOF with padlocks, master
switches, or by removing starter keys.
• DON'T FORCE TOOL. It will do the job better and safer at the
rate for which it was designed.
• USE RIGHT TOOL. Don't force tool or attachment to do ajob for
which it was not designed.
• USE PROPER EXTENSION CORD. An extension cord must
have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the
capacity of the cable, that is 16 gauge has more capacity than
18 gauge. An undersized cord will cause a drop in line voltage
resultinginlossofpowerandoverheating.Whenusingmorethan
oneextension to make up the total length, be sure each individual
extension contains at least the minimum wire size. The following
table 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.

Additional Safety Rules for Chop Saw
• Always wear proper eye and respiratory protection.
• Before using, inspect the cutting wheel for cracks or flaws.
If such a crack or flaw is evident, discard the wheel. The
wheel should also be inspected whenever you think the tool
may have been dropped. Flaws may cause wheel breakage.
• When starting the tool with a new or replacement wheel
or if you are unsure of the condition of the wheel, hold the
tool in a well protected area and let H run for one minute. If
the wheel has an undetected crack or flaw, ff should burst
in less than one minute. Never start the tool with aperson inline
with the wheel This includes the operator.
• In operation, avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the wheel for
cracks or flaws.
• Clean your chop saw periodically following the procedure in this
manual.
• Do not remove wheel guards or base.
• ALWAYS USE THE VISE OR SPECIAL FIXTURE TO CLAMP
WORK SECURELY. Other aids such as spring, bar, or C-clamps
may be appropriate for certain sizes and shapes of workpiece. Use
care in selecting and placing these clamps and make a dry run
before making a cut.
• Use only 14" type 1 wheels rated at 4100 rpm orhigher.
• Allow cut off parts to cool before handling.
• Do not attempt to cut wood or plastic with this tool
• NEVER CUT MAGNESIUM WITH THIS TOOL.
• Use chop saw in a well-ventilated area.
• Turn chop saw off before removing any pieces from the base.
• DO NOT CUT ELECTRICALLY LIVE MATERIAL.
• DO NOT USE CIRCULAR SAW BLADES OR ANY OTHER
TOOTHED BLADES WITH THIS TOOL. Serious injury may
result.
• DO NOT OPERATE THIS TOOL NEAR FLAMMABLE
LIQUIDS, GASES OR DUST. Sparks or hot chips from cutting or
arcing motor brushes may ignite combustible materials.
• Do not use the side of the abrasive wheel as a deburring grinder.
This will substantially weaken the wheel creating an unsafe
condition. The wheel may come apart.
_CAUTION: Wear appropriate hearing protection during use.
Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
ACAUTION: Spark deflector will get hot. Avoid touching or
adjusting while hot. Keep cordset and materials away from spark
deflector.
AWARNING: Some dust created by power sanding, sawing,

known to the State of California to cause cancer, birth defects, or
other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.
_,WARNING: Use of this tool can generate and/or disperse dust,
which may cause serious and permanent respiratory or other injury.
