Extension Cords; Electrical Connection - Craftsman 315.220380 Owner's Manual

EXTENSION CORDS
Use only 3-wire extension cordsthat 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-
sion cord heavy enough to carry the current that the
tool will drew. An undersizedextension cord will
cause a drop in line voltage, resultingin a loss of
power and causing the motor to overheat. Use the
chart provided below to determine the minimumwire
size required in an extension cord. Only roundjack-
eted cords listed by Underwriter'sLaboratories(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 tool outdoors,use an exten-
sion cord that is designed for outside use. This is
indicated by the letters WA on the cord'sjacket.
Before using an extension cord, inspectit for Looseor
exposed wires and cut or worn insulation.
_1_ CAUTION: Keep the cord away from the cutting
area and positionthe cord so that it will not be
caught on lumber, tools, or other objectsdudng
cutting operations.
ELECTRICAL CONNECTION
Your Sears Craftsman Radial Arm Saw is powered by
a precisionbuilt electric motor. It shouldbe connected
to a power supply that Is 120 volts, 60 Hz, AC only
(normal household current). It should be connected
to a 240 volt power supply only If It has been reset
according to the Instructions in this manual. The
motor has been set at the factory for 120 volts; if it is
reconnectedto operate at 240 volts,the main power
cord plug and any receptacle must be replaced with
devices rated for 240 volts. This tool will not operate
on direct current (DC). A substantialvoltage drop will
cause a loss of power and the motorwill overheat. If
the saw does not operate when plugged intoan outlet,
double check the power supply.
SPEED AND WIRING
The no-load speed of your saw is approximately3,600
rpm. This speed is not constant. For voltage, the
wiring in a shop is as importantas the motor's horse-
power rating. A line intendedonly for lightscannot
propedy carry a power tool motor. Wire that is heavy
enough for a shortdistance will be too light for a
greater distance. A line that can supportone power
tool may not be able to supporttwo or three tools.
GROUNDINGINSTRUC_ONS
In the event of a malfunctionor breakdown, grounding
providesa path of least resistancefor electriccurrent
to reduce the riskof electricshock.This tool is
equipped with an electriccord having an equipment-
groundingconductorand a groundingplug. The plug
must be plugged intoa matchingoutlet that is propedy
installedand groundedin accordance with all local
codes and ordinances.
Do not modifythe plug provided. If it willnot fit the
outlet, have the properoutlet installedby a qualified
electrician. Improperconnectionof the equipment-
groundingconductorcan result in a risk of electric
shock. The conductorwith insulationhaving an outer
surface that is green with or withoutyellow stripesis
the equipment-grounding conductor.If repair or
replacement of the electriccordor plug is necessary,
do not connectthe equipment-grounding conductorto
a live terminal.
Check with a qualifiedelectricianor service personnel
if the groundinginstructionsare not completely
understood,or if in doubt as to whether the tool is
properlygrounded.
Repair or replace a damaged or worn cord immedi-
ately.
This tool is intendedfor use on a circuitthat has an
outlet like the one shownin Figure I. It also has a
groundingpin like the one shown.
