BASIC OPERATION OF THE RADIAL
ARM SAW
A radialarm saw can be usedfor straight-linecutting
operationssuch as cross cutting,ripping,mitering,
beveling,compoundcutting,and resawing.Itcan
make dado or moldingcutswithspecialattachments.
This sew isdesignedto cutwoodand woodcomposi-
tionproductsonly.
The three-prongplug mustbe pluggedintoa match-
ingoutletthat is properlyinstalledand grounded
accordingto all localcodes and ordinances.Improper
connectionofthe equipmentcan resultin electric
shook.Check with an electricianor service personnel
ifyou are unsureabout propergrounding.Do not
modifythe plug;ifitwill notfit the outlet,have the
correctoutletinstalledby a qualified electrician.Refer
tothe Electricalpage ofthis manual.
TYPES OF CUTS
See Figure35.
The radial sew makes crosscutsparallelwiththe arm'
(acrossthe grain),and ripcutssquaretothe arm (with
the grain). Each can be made withthe blade vertical
or beveled. Instructionsfor makingeach kindofcut
are givenlater inthis section.
A WARNING: All bladesand cuttingaccessories
am,
mustbe ratedfor at least5,000 rpmto prevent
possibleinjury.
CROSSCUTS
Crosscutsare made parallelto the arm. The blade is
pulledalong the length ofthe radialarm ,withthe wood
secured.
There are severaltypes ofcross cuts.A crosscut
shows 0"on the miterscale (arm straight)and 0"on
the bevel scale (blade straight).A mitercutis made
with the radial armangled and the blade straight.A
bevel cutis producedwiththe arm straightand the
blade angled.
A final type of crosscut isthe compound crosscut.
Boththe arm and the blade are angled. Bethoroughly
familiar with makingcresscuts, bevel cuts, and miter
cuts beforetryinga compoundmitercut.
Note: incross cuts,the blade teeth pointdownas
they strikethe wood. In ripcuts, theteeth point
up as they strikethe wood.
_ WARNING: NEVER make a cross cutwiththe
shortedge ofthe woodparallelto thefence. Kick
backis likelyto occur,causing the workpieceto
be thrownbackat you.Treat such a workpiece
as a ripcut.
RIP CUTS
In dpcuts, the yoke isrotated90" leftor rightand
lockedin place.The wood mustridefirmlyagainstthe
ripfence. There are twoorientationsof ripcuts- the
in-ripand the out-rip.The in-rippositionprovides
better visibility.Out-ripcutscan also be made withthe
bladebeveled.
In an in-ripcut, theyoke is rotatedto the left,which
putsthe blade in between the columnand the motor.
The woodisfed from the righthandside.
In an out-ripcut, the blade isin front ofthe motor,and
the wood isfed from the left.Out-rip cuttingis recom-
mendedonlywhen the blade isset 12 in.or more
fromthe fence.
_1= WARNING: Alwaysmake surethe blade guard
and anti-kickbackpawlsare in place and working
propedywhen making ripcutsto avoidpossible
injury.
WARNING: Always usea pushstickwith small
pieces ofwood, and alsotofinishthe cutwhen
rippinga long narrowpiece ofwood, to prevent
yourhandsfrom gettingcloseto the blade.
