Forthis tool an AWG (AmericanWire Gauge)size ofat least 14-gauge is recommended
for anextension cord of 25-ft.or less inlength. Use 12-gauge foran extensioncord of
50-ft,Extension cords 100..ft,or longerare not recommended,Remember, a smaller
wire gauge size hasgreater capacity than alarger number (14-gaugewirehas more

[Z_ CAUTION: Bladescoast after saw Is switchedoff. ]
1, KEEPyour bodypositioned to eitherside of the saw blade and not in direct line
with the saw blade. Kickbackcouldcausethesawto jump backwards.
(See"Ktckback...WhatCausesItandWaystoHelpPreventIt"onpages1B.19 and20).
2.DO NOT reach underneath the workplece.The blade extendsbeneaththe
workplacewhencuttingand couldcauseinjury.
l_r_j.-=J"_ When sawingthrough aworkplece,the lower bladeguard and
base DONOT covertheblade.The bladeIs belowthe lowerbladeguardend base
(Pagi_25).ALWAYSKeepyour handsandfingers awayfrom thecuttingarea.
CAUTION: This circularsaw DOESNOThave thestandard RETRACTABLE
LOWERBLADE GUARDSystemfound on standard circularsaws.ONTHIS saw
the lowerbladeguard Isan Integralpart of the saw's base(cutting platform)and
ONLYenclosesthe bladewhen it Is ABOVE thebase.

SAFETY RULES FOR THE MULTI-PURPOSE /PLUNGE ACTION
3-IN. CIRCULAR SAW cont.
/_ CAUTION: When the blade Is plunged belowthe base to make the cut,
the blade Is entirely exposed underneath the workplace until It cutsthrough and
clearsthe workplece;at this point the blade guard and base wilt automatically
"DROP" downand lock the bladeABOVE the base,enclosing the blade In the
upperand lower bladeguard.
CAUTION: FAMILIARIZEYOURSELFWITHTHIS BLADE GUARDSYSTEM
and the PLUNGEACTION (lowering blade to desired depth) BEFOREUSING
THIS SAW (See Page 18,Figs. 4 and 4e).
3_CHECK the Blade GuardRelease Leverand the LowerBlade Guardand Base
BEFOREeach use, DO NOT OPERATE the saw if the }owerblade guard and base
does notmove freely and DROP DOWN INSTANTLY,and the blade guard release
leverdoes net automaticallyengage the upperblade guard, AFTER cut Ismade
and blade c{earstheworkptece(See Page 18 and 19).
Iz_ CAUTION: Never clamp or tiethe BladeGuard Release Lever and the
Lower BladeGuard and Base in the raised position exposingthe blade.This
would notallow the lower Blade Guardand BaseAssembly to function properly
after the cuttingoperation, Increasing the risk of serious personal Injury.
4.ONLYUSE themanual Blade Guard Release Leverto false thebase, loweringthe
bladeto thedesired depth-of-cut whenbeginning the cuttingoperatlon_
5_If thesaw Isaccidentally dropped, theblade guard releaseleverand the lowerblade
guard and base couldbe damaged or broken. Lower and raisethe blade manually
(seepage 18, Figs.4 and 4a) to be sure the releaselever,guard and base all operate
properly.
6otf the BladeGuardRelease Leveror LowerBlade Guard and Baseor anyother part of
the saw isnot operating properly, thesaw MUST BEserviced before use.
7.ALWAYSmake sure that the LowerBlade Guard and Base ts covering the blade,and
the Blade Guard Release Leverhas engaged and locked theblade ABOVE the base
BEFOREplacingthe saw down on a workbenchor floor,
Placingthe sawdown beforethe lowerblade guard and base and blade guard release
leverhaveproperly closed and locked could leavethe blade exposed below thebase,
Increasingthe risk of seriouspersonal Injury.Make noteof the time It takes for the
blade to stopsplnnlng and the guard, base and release leverto drop and lock intothe
guarded position,
8.NEVER hold the piecebeing cut Inyour hands or across yourlegs, It isimportantto
support theworkplace propedy tnorder to minimizebody exposure,blade binding, or
loss ofcontrol
9-HOLDTOOL by Insulatedgripping surfaces (handle/saw's body)when performing an
operationwherethe cutting tool may contact hidden wiring or Its own cord.Contactwith

SAFETY RULES FOR THE MULTI-PURPOSE /PLUNGE ACTION
3-IN. CIRCULAR SAW cont.
10rALWAYSclampthe workplece securelyso Itwill not move when making the cut.
11oWhen ripping, ALWAYSUSE a rip fence or straight edge guide.This Improves
the accuracy of the cut and reducesthe chance of the blade binding.
[ WARNING: ONLY USEthe bladesthat are designated for usewith this
saw; correct size,shape and arbor hole. Other blades could runerratically and
cause loss of control, resulting In serious Injury (see pages 16 and 17).
12,NEVER use damagedor Incorrectblade washers or bolts. The bladewashers
and boltswere specially designed for yoursaw,for optimum performance and
safety of operation,
13_ONLYUSE the designatedbladesfor cuffing the type of material for whichthey
are recommended. Cutting materialsthat are NOTrecommended could cause
blade breakage and lossof control, resulting In serious Injury,
14,NEVER cut more than one piece at a time. DO NOT STACKmore than one
workplece on the worktable at a time.
15,AVOIDawkward operations and hand positions where a sudden slip could
cause your handto moveintothe blade.
16.NEVER reach Intothe cutting pathof the blade.
/_ WARNING: Some dust created by using power tools contains chemicals
known to the State of California to cause cancer and birth defects or other
reproductive harm_Some examples of these chemicals are:
•Lead from lead-based paints.
•Crystalline silica from bricks and cement and other masonry products_
•Arsenic and chromium, from chemically treated lumber.
Your risk from these exposures varies, depending upon how often you do this
type of work.To reduce your exposure to these chemicals:
• Work in awell-ventilatedarea°
,,Work with approved safety equipment,such as those dust masks thatare specially
designed tofilter out microscopic particles..
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling
and other construction activities.Wear protective clothing and wash exposed
areas with soap and water.
Allowing dust to get tntoyour mouth, eyes, or lay on the skin may promote absorption of
harmful chemicals.
Z_ WARNING: Use of this tool can generate and/or disburse dust, which may
cause serious and permanent respiratory or other Injury. Always use NIOSH/OSHA
approved respiratory protection appropriate for the dust exposure. Direct particles
away from face and body.
