THESE
INSTRUCTIONS
WORK AREA
•
Keep your work area clean
and
well lit. Cluttered
benches
and dark areas invite
accidents.
•
Do not operate power tools in explosive
atmospheres,
such as in the presence of
flammable
liquids, gases, or dust. Power tools create sparks which may ignite the dust or
fumes.
•
Keep bystanders,
children,
and visitors away while operating
a power tool Distractions
can cause you to lose control.
ELECTRICAL
SAFETY
•
Double insulated
tools are equipped
with 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 quafified
electrician
to
install
a polarized
outlet. Do not change
the plug in any way. Double insulation []
eliminates the need for the three wire grounded power cord and grounded power supply
system.
• Avoid
body
contact
with grounded
surfaces
such as pipes, radiators,
ranges
and
refrigerators.
There is an increased risk of electric shock if your body is grounded.
•
Don't expose power tools to rain or wet conditions.
Water entering a power tool will
increase the risk of electric shock.
•
Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged
cords immediately.
Damaged cords increase the risk of electric shock.
•
When operating
a power tool outside,
use an outdoor
extension
cord marked "W-A"
or "W." These cords are rated for outdoor use and reduce the risk of electric shock. 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 following table shows the correct size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.

of drugs, alcohol, or medication.
A moment of inattention while operating power tools may result in serious personal injury,
•
Dress properly. Do not wear loose clothing
or jewelry. Contain long hair. Keep your hair,
clothing,
and gloves away from moving parts. Loose clothing, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and should also be avoided.
•
Avoid accidental
starting.
Be sure switch is off before plugging
in. Carrying tools with
your finger on the switch or plugging in tools that have the switch on invites accidents.
•
Remove adjusting
keys or wrenches
before turning
the tool on. A wrench or a key that
is left attached to a rotating part of the tool may result in personal injury,
•
Do not overreach.
Keep proper
footing
and balance
at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
•
Use safety equipment.
Always
wear eye protection.
Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
•
Use clamps
or other practical
way to secure and support
the workpiece
to a stable
platform.
Holding the work by hand or against your body is unstable and may lead to loss of
control
•
Do not force tool Use the correct
tool for your application.
The correct tool will do the job
better and safer at the rate for which it is designed.
•
Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with
the switch is dangerous and must be repaired.
•
Disconnect
the plug from the power source before making any adjustments,
changing
accessories,
or storing
the tool
Such preventative safety measures reduce the risk of
starting the tool accidentally,
•
Store idle tools
out of reach of children
and
other
untrained
persons.
Tools are
dangerous in the hands of untrained users.
•
Maintain
tools with care. Keep cutting
tools sharp and clean. Properly maintained tools,
with sharp cutting edges are less likely to bind and are easier to control
•
Check for misalignment
or binding of moving parts, breakage
of parts, and any other
condition
that may affect the tool's operation,
ff damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
•
Use only accessories
that are recommended
by the manufacturer
for your

Saws
•
DANGER! Keep hands away from cutting area and blade. Keep your second hand on
auxiliary handle or motor housing./f
both hands are holding the saw, they cannot be cut
by the blade.
•
Do not reach underneath
the workpiece.
The guard cannot protect you from the blade
below the workpiece
•
Never hold piece being cut in your hands or across your leg. Secure the workpiece
to
a stable platform.
It is important to support the work properly to minimize body exposure,
blade binding, or loss of control.
•
Hold tool by insulated
gripping
surfaces
when performing
an operation
where the
cutting
tool may contact hidden wiring or its own cord. Contact with a "five" wire will also
make exposed metal parts of the power tool "live" and shock the operator.
•
Always use blades with correct size and shape (diamond
versus round) of arbor holes.
Blades that do not match the mounting hardware of the saw will run eccentrically, causing
loss of control.
•
Never use damaged or incorrect
blade washers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum performance
and safety of operation.
•
Keep your body positioned
to either side of the blade, but not in line with the saw
blade.
•
Blades coast after turn off. Serious personal injury may result.
•
Don't unplug if plug or receptacle is wet. Disconnect the fuse or circuit breaker that supplies
power to the tool. Then unplug and examine for presence of water in the receptacle.
•
Wait for the saw to come to a complete
stop. An unprotected, coasting blade will cause
the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the
blade to stop after switch is released.
•
Do not use to cut wood or metal.
•
Never
use toothed
blades.
This tool is not equipped
with a
lower guard.
A DANGER:
Keep
hands
away
from
cutting
area and
blade.
Personal injury may result.
