Craftsman 315.220381 Saw User Manual


 
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
groundingplugs and 3-pole receptacles that accept
the tool's plug. When using a power tool at a consider-
able distance from the power source, use an exten-
sioncord heavy enough to carry the current that the
tool willdraw. An undersized extension cord will
cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire
size required in an extension cord. Only round jack-
eted cords listed by Underwriter's Laboratories (UL)
should be used.
Length of Extension Cord Wire Size (A.W.G.)
Up to 25 feet 14
26-100 feet 12
When workingwith the tooloutdoors,use an exten-
sioncord that is designed for outsideuse. This is
indicatedbythe letters WA on the cord'sjacket.
Before usingan extension cord, inspectitfor looseor
exposed wires and cut or worn insulation.
_k CAUTION: Keep the cordaway from the cutting
area and position the cordso that it will not be
caughton lumber, tools,or other objectsduring
cuttingoperations.
ELECTRICAL CONNECTION
Your Sears Craftsman Radial Arm Saw ispowered by
a precisionbuiltelectric motor. It shouldbe connected
toa power supply that is 120 volta, 60 Hz, AC only
(normal household current). Itshould be connected
toa 240 volt power supply only if it has been reset
according to the Instructions inthis manual. The
motorhas been set at the factory for 120 volts;if it is
reconnectedto operate at 240 volts,the main power
cord plugand any receptacle mustbe replacedwith
devices rated for 240 volts. This toolwillnot operate
on direct current (DC). A substantialvoltage drop will
cause a lossof power and the motorwilloverheat. If
the saw does not operate when plugged intoan outlet,
double checkthe power supply.
SPEED AND WIRING
The no-load speed of yoursaw is approximately 3,600
rpm. This speed is notconstant. For voltage, the
wiring in a shop isas importantas the motor's horse-
power rating. A line intendedonlyfor lightscannot
properlycarry a power toolmotor. Wire that isheavy
enough for a shortdistance willbe too lightfor a
greater distance. A linethat can supportone power
tool may not be able to supporttwo or three tools.
GROUNDINGINSTRUCTIONS
In the event of a malfunctionor breakdown, grounding
providesa path ofleast resistance for electriccurrent
to reduce the risk ofelectricshock. Thistool is
equippedwith an electric cordhaving an equipment-
groundingconductorand a grounding plug.The plug
mustbe plugged intoa matching outletthat isprepedy
installedand groundedin accordance withall local
codes and ordinances.
Do not modify the plug provided. If itwillnot fit the
outlet, have the properoutlet installedbya qualified
electrician. Improperconnectionof the equipment-
groundingconductorcan resultin a riskofelectric
shock.The conductorwith insulationhaving an outer
surfacethat isgreen with or withoutyellowstripesis
the equipment-groundingconductor.Ifrepair or
replacement ofthe electriccordor plugis necessary,
do not connectthe equipment-groundingconductorto
a live terminal.
Check with a qualified electricianor service personnel
ifthe groundinginstructionsare notcompletely
understood,or ifin doubt as to whether the toolis
propedygrounded.
Repair or replace a damaged orworncord immedi-
ately.
This toolis intendedfor use on a circuitthat has an
outlet likethe one shownin Figure 1.It also hasa
groundingpinlike the one shown.
