KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don't use power tools
in damp
or wet locations. Keep work area well lit. Don't expose power tools to rain.
Don't use tool in presence of flammable liquids or gases.
KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
STORE IDLETOOLS. Whennotinuse, tools should be stored
in dry, and high
or locked-up place
- out of reach of children.
DON'T FORCETOOL.
It will dothejob betterandsafer at the ratefor which
it was intended.
USE RIGHT TOOL. Don't force small tool or attachment to do the job of a
heavy-duty tool. Don't use tool for purpose not intended.
DRESSPROPERLY. Don't wear loose clothingorjewelry. They canbe caught
in moving parts. Rubber gloves and nonskid footwear are recommended
when workingoutdoors. Wear protective hair covering to contain long hair.
USE SAFETY GLASSES. Also use face or dust mask
if cutting operation is
dusty.
DON'T ABUSE CORD. Never carry toolby cordor yank
it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it frees both hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructionsfor lubricatingand changing acces-
sories. Inspecttoolcords periodicallyandifdamaged, haverepairedby autho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from
oil and grease.
DISCONNECTTOOLS. When not
in use, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removedfromtool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry plugged-intool withfinger
on switch. Be sure switch is OFF when plugging
in.
16. OUTDOOR USE EXTENSIONCORDS. Whentool is usedoutdoors, use only
extension cords intended for use outdoors and
so marked.
17. STAY ALERT. Watch what youare doing, use common sense. Don't operate
tool when you are tired.
18. CHECK DAMAGEDPARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checkedto determine that
it will
operate properly and performitsintended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced by an authorized
service center unless otherwise indicated elsewhere in this instruction
manual. Havedefective switches replacedby authorizedservicecenter. Don't
use tool if switch does not turn
it on and off.
19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENTPARTS.Whenservicing, useonly identicalreplacementparts.
21. POLARIZEDPLUGS. To reducethe risk of electric shock, this equipment 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,
reversethe plug. If
it still does not fit, contactaqualifiedelectriciantoinstall
the proper outlet. Do not change the plug in any way.
VOLTAGE WARNING: Before connectingthe tool toa power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplateof the tool. A power source withvoltage greater than that specified
for the tool can result
in SERIOUS INJURYto the user - as well as damage to
the tool.
If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating
is harmful to the motor.

Use Of Extension Cord
If the extensioncord isintendedto be usedoutdoors, the cord shall be marked
withthe suffix W-A followingthe cordtype designation, for example
- SJTW-
A, to indicate
it is acceptable for outdoor use. Use an extension cord heavy
enoughtocarry the currentthe tool will draw. Undersize cord will cause a drop
in linevoltage resulting in loss of power and over-heating. Makesure the exten-
sion cord is
in good condition before using. Use the table below to determine
the proper wire size required in the extension cord.

ADDITIONAL SAFETY RULES
1. Keep Guards In Place and In Working Order.
Never wedge or tie lower guard open. Check operation of lower guard be-
fore eachuse. Don’t use
if lower guarddoes notclose briskly over saw blade.
CAUTION: Ifsaw isdropped, lowerguard may be bent, restrictingfull return.
2. Keep Blades Clean and Sharp.
Sharp blades minimize stalling and kickback.
3. DANGER: Keep Hands Away From Cutting Area.
Keep hands away from blades. Don’t reach underneath work while blade
is rotating. Don’t attempt to remove cut material when blade is moving.
CAUTION: Blades coast after turn off.
4. Support Large Panels.
Largepanelsmustbe supported as
shown
in Fig. 1 tominimizetherisk
of blade pinching and kickback.
When cutting operation requires
the restingofthesaw onthe work
piece, the saw shall be rested on
the larger portion and the smaller
piece cut off.
To avoid kickback, do support board
or panel near the cut.
Fig. 1
Don’t support board or panel away
from the cut.
Fig.,
5. Use Rip Fence.
6. Guard Against Kickback.
Always use a fence or straight edge guide when ripping.
Kickbackoccurswhenthesaw stalls rapidlyand
is drivenbacktowardsthe
operator. Releaseswitchimmediately if bladebindsor saw stalls. Keepblades
sharp. Support large panels as shown
in Fig. 1. Use fence or straight edge
guide when ripping. Don‘t force tool. Stay alert exercise control. Don’t re-
move saw from work during a cut while the blade
is moving.
5

NEVER place your hand or fingers
behindthe saw.
If kickback occurs,
the saw could easily jump back-
wards over your hand, possibly
causing severe injury.
Fig.
7. Lower Guard. Raise lower guard with the retracting handle.
8. Adjustments. Before cuttingbesure depthand bevel adjustments are tight.
9. Use Only Correct Blades In Mounting. Don't use blades with incorrect size
holes. Never use defective or incorrect blade washers or bolts.
IO. Avoid Cutting Nails. Inspect for and remove all nails from lumber before
cutting.
1 1. Whenoperating the saw, keepthe
cord away from the cutting area
andposition
it so that it willnotbe
caught on the workpiece during
the cutting operation.
Operatewithproper handsupport,
proper workpiece support, and
supply cordroutingaway from the
work area.
A typical illustration of proper hand
support, workpiece support, and
supply cord routing.

WARNING :
It isimportanttosupport the workpiece properly and toholdthe saw firmly
toprevent
loss of controlwhich couldcause personal injury. Fig. 4 illustrates
typical hand support of the saw.

12. Placethe wider portionof the saw baseonthat part of the workpiecewhich
issolidly supported, not
on the sectionthat will fall off when the cutismade.
As examples, Fig.
5 illustrates the RIGHT way tocut off the end of a board,
and Fig.
6 the WRONG way. If the workpiece is short or small, clamp it down.
DON'T TRY
TO HOLD SHORT PI ECES BY HAND!

Set the base
plate on the workpiece to be cut without
the blade making any contact. Then turn
the tool on and wait untilthe blade attains
full speed. Now simply move the tool for-
ward over the workpiece surface, keeping
it flat and advancing smoothly until the
sawing
is completed. To get clean cuts,
keep your sawing line straight and your
speed of advance uniform.

Guide rule
The handy guide rule allows you to
do
extra-accuratestraight cuts. Simply slide
the guide rule up snugly against the side
of the workpiece and secure
it in position
with the screw on the front of the base.
It
makes repeated cuts of uniformworkpiece
width possible, too.
