Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains
chemicals 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, cement and other masonry products
oArsenic and chromiumfrom chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work ina well ventilated area and work with approved Safety equipment such as
dust masks that are specially des}gnarl to filter out microscopic particles.

plug the tool in until you have read and _mderstood the
following
1. READ and become familiar with the entire Operators
Manual. LEARN the tool's application, limitations and
possible hazards.
2. KEEP GUARDS IN PLACE and in working order,
3. REMOVE ADJUSTING KEYS AND WRENCHES.
Form the habit of checking to see that keys and
adjusting wrenches are removed from the tool before
turning ONe
4. KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents.
5. DON'T USE IN DANGEROUS ENVIRONMENTS.
Don't use power tools in damp locations, or expose
them to rain or snow. Keep work area well lighted.
6. KEEP CHILDREN AWAY. All visilors and bystanders
should be kept a safe distance from work area

and safer at the rate for which it was designed.
9. USE THE R1Gt'rr TOOL. Do not force the tool or an
attachment to do a job for which it was not designed,
10,USE PROPER EXTENSION CORDS. 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 result in a drop in line voltage
and in loss of power which will cause the tool to
overheat. The table on page 5 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.
11,WEAR PROPER APPAREL. Do not wear loose
¢10thihg,gloves, neckties, dngs, bracelets, c rother

POWER SUPPLY AND MOTOR SPECIFICATIONS
The AC motor used _n this saw is a uriiverse[.
nonreversible type. See "MOTOR _ in the "PRODUCT
SPECIFICATIONS" seciion on page 2.
To avoid electrical hazards, fire hazard_ or damage 1o
the tool, use proper ,circuit protection. Your saw is wired
at the factory for 120V operatbn Connect to a 120V, 15
Amp circuit and use a I5 amp, time delay lose or circuit
breaker, To avoid shock or fire, if power cord is worn or

immediately.
17.NEVER reach around the saw blade

ELECTRICAL REQUIREMENTS - cont'd
DOUBLE INSULATED []
The power tool is double insulated to provide a double
thickness of insulation beb.veen you and tool,s-electrical
system. All exposed metal partsare 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 eleclricat shock, this saw has a
polarized plug (one blade is wider than the other] Tllis
plug willfit in a polarized outlet only one way. If|he plug
does not fit fully in the curie! reverse the plug tf it st;tl
does not fit, contact a qualified electrician to install the
proper outlet. DO riot change the plug in any way.
Double insulation does not take the place o! normal
safety precautions when operating this tool
To avoid electrocution:
1.Use only identical replacement parts when servicing a
toolwith double Insulation. Servicing should be
performed by a qualified technician
2, Do not use power tools tn wet or damp locations or
expose them to ra'=nor snow.
MOTOR SAFETY PROTECTION
IMPORTANT:
Toavoid motor damage, the motor sl_outd be blown out
or vacuumed frequently to keep sawdust from intedefing
with the motor ventilation,
t. CONNECT this saw to a 120V, 15 amp. circuitwith a
15 amp, time delay fuse or circuit breaker. Using the
wrong size fuse can damage the motor..
2 If the motor won't start, release the tdgger swilch
immediately, UNPLUG "THE SAW, Check the saw
blade t.omake sure it turns freely< If the blade is Iree,
try to sled the saw again. If the motor still does not
start, refer to lhe "TROUBLESHOOTING GUIDE"
3. If the tool suddenly stalls while cuttingwood, release
the tdgger swltch, unplug the tool, and free the blade
from tile wood. The saw may now be started and the
cut flnisha&
4. FUSES may "blow" or circuit breakers may trip
frequently if:
a. MOTOR is overloaded - ovedoading can occur if
you feed too rapidly or make too many startJstops
in a shod 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 widng, Always check the
connections, the load and supply circuit ifthe motor
doesn't run well. Check minimum gauge for the lenglh
of cord you are using on the chad below,
GUIDELINES FOR EXTENSION CORDS
Use aproper extension cord. Make sure your
exlension cord is in good condition. When using an
ex'lension 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, resulling in loss of
power and cause overheating. The table below shows
the correct size to use depending on cord length and
nameplate ampere rating. II in doubt, use the nexl
heavier gauge The smaller lhe gauge number, the
heavier the cord.
Be sure your extension cord is property wired and in
good condition. Always replace a damaged extension
cord or have it repaired by a qualified person before
using iL 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 # 12 wire and should be
protected with a 15 Amp lime delay fuse. Before
connecting the to01to the power line, make sure the
switch isin the OFF position and the electric current is
raled the same as the current stamped on ti_e motor
nameplate, running at a lower voltage will damage the
motor.
