RULES FOR SAFE OPERATION

Page 5
■BLADES COAST AFTER TURN OFF.
■NEVERUSEINANEXPLOSIVEATMOSPHERE. Normal
sparking of the motor could ignite fumes.
■INSPECT TOOL CORDS PERIODICALLY. If damaged,
have repaired by a qualified service technician at an
authorized service facility. The conductor with insulation
havinganoutersurfacethatisgreenwithorwithoutyellow
stripes is the equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary, do
not connect the equipment-grounding conductor to a live
terminal. Repair or replace a damaged or worn cord
immediately. Stay constantly aware of cord location and
keep it well away from the rotating blade.
■INSPECT EXTENSION CORDS PERIODICALLY and
replace if damaged.
■KEEPTOOLDRY,CLEAN,ANDFREEFROM OIL AND
GREASE. Always use a clean cloth when cleaning.
Never use brake fluids, gasoline, petroleum-based
products, or any solvents to clean tool.
■STAY ALERT AND EXERCISE CONTROL. Watch what
youaredoingandusecommonsense.Donotoperatetool
when you are tired. Do not rush.
■DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
■GUARD AGAINST KICKBACK. Kickback occurs when
the blade stalls rapidly and workpiece is driven back
towards the operator. It can pull your hand into the blade
resultingin serious personalinjury.Stayoutof bladepath
and turn switch off immediately if blade binds or stalls.
■USE RIP FENCE. Always use a fence or straight edge
guide when ripping.
■SUPPORT LARGE PANELS. To minimize risk of blade
pinching and kickback, always support large panels.
■BEFORE MAKING A CUT, BE SURE ALL
ADJUSTMENTS ARE SECURE.
■USEONLYCORRECTBLADES.Donotusebladeswith
incorrectsizeholes.Neverusebladewashersorboltsthat
aredefectiveorincorrect.Themaximumbladecapacityof
your saw is 10 in. (254 mm).
■AVOIDCUTTINGNAILS.Inspectforandremoveallnails
from lumber before cutting.
■NEVER TOUCH BLADE or other moving parts during
use.
■NEVER START A TOOL WHEN ANY ROTATING
COMPONENTISINCONTACTWITHTHEWORKPIECE.
■DO NOT OPERATE THIS TOOL WHILE UNDER THE
INFLUENCE OF DRUGS, ALCOHOL, OR ANY
MEDICATION.
■GROUND ALL TOOLS. If tool is equipped with three-
prongplug,itshouldbepluggedintoathree-holeelectrical
receptacle.
■WHENSERVICINGuseonlyidenticalRyobireplacement
parts. Use of any other parts may create a hazard or
cause product damage.
■REMOVE ALL FENCES AND AUXILIARY TABLES
before transporting saw. Failure to do so can result in an
accident causing possible serious personal injury.
■ALWAYS USE BLADE GUARD, RIVING KNIFE, AND
ANTI-KICKBACK PAWLS on all "through-sawing" op-
erations. Through-sawing operations are those in which
the blade cuts completely through the workpiece as in
ripping or crosscutting. Keep the blade guard down, the
anti-kickback pawls down, and the riving knife in place
over the blade.
■ALWAYS SECURE WORK firmly against rip fence or
miter fence.
■ALWAYSUSEAPUSHSTICKFORRIPPINGNARROW
STOCK.Apushstickisadeviceusedtopushaworkpiece
through the blade instead of using your hands. Size and
shape can vary but the push stick must always be nar-
rower than the workpiece to prevent the push stick from
contacting the saw blade. When ripping narrow stock,
always use a push stick, so your hand does not come
close to the saw blade. Use a featherboard and push
blocks for non-through cuts.
■NEVER perform any operation "freehand" which means
using only your hands to support or guide the workpiece.
Always use either the rip fence or miter fence to position
and guide the work.
■NEVERstandorhaveanypartofyourbodyinlinewiththe
path of the saw blade.
■NEVER reach behind, over, or within three inches of the
blade or cutter with either hand for any reason.
■MOVETHERIPFENCEoutofthewaywhencrosscutting.
■NEVER use rip fence as cutoff gage when crosscutting.
■NEVER attempt to free a stalled saw blade without first
turning the saw OFF and disconnecting the saw from the
power source.
■PROVIDE ADEQUATE SUPPORT to the rear and sides
ofthesawtableforwideorlongworkpieces.Useasturdy
"outrigger" support if a table extension more than 24
inches long is attached to the saw.
■AVOID KICKBACKS (work thrown back toward you) by:
A. Keeping blade sharp.
B. Keeping rip fence parallel to the saw blade.
C. Keepingrivingknife,anti-kickbackpawls,and blade
guard in place and operating.
D. Notreleasingtheworkbeforeitispushedalltheway

WARNING:
Although some of the illustrations in this manual are
shown with the blade guard removed for clarity, do not
operatethesawwithoutthebladeguardunlessspecifically
instructed to do so.
OPERATING COMPONENTS
Theupperportionof the blade projectsupthroughthetable,
surrounded by an insert called the throat plate. To cut wood
at a bevel, the blade must be tilted, using the blade adjust-
menthandle, scale, andbevelindicatorfound on thefrontof
thecabinet.Insidethecabinet, adjustable positive stopsare
provided for 0ºand 45º.
The sliding miter table assembly is used for all crosscutting
operations.The miter fenceiseasilyadjusted to cutwoodat
anangleby looseningtheadjustingclamp,settingthefence
to the miter scale, and retightening the clamp. The sliding
miter table, which rests on a base mounted on the rails, can
be repositioned along the rails for wide work. It can be
reversed so the projecting base is in the back. It can also be
movedfromtherightsidetotheleftsideasneeded.Withthe
miterfenceremovedthemitertableoffersadditionalsupport
for other operations such as ripping.
Your saw includes a rip fence and an accessory table. The
accessorytable canbemoved from therightside of thesaw
to the left side as needed. The rip fence is used to position
work that will be cut lengthwise. A scale on the front rail
shows the distance between the rip fence and the blade.
The riving knife is a metal device directly behind and above
the blade. It is used to help keep the cut wood from binding
together and causing possible kickback. It is very important
tousethe riving knifeforallthrough-sawingoperations. The
anti-kickbackpawlsaretoothedplatesmountedontheriving
knife. Their teeth point away from the work in case the work
should be pulled back, toward the operator. Then the teeth
dig into the wood to help prevent or reduce the possibility of
kickback.
