GROUNDING INSTRUCTIONS
WARNING: If themachine doesnotcome
wired to run, theelectricals andmotor
wiring must be doneby aqualified
electrician. Themachine mustbe
properly grounded to help avoid
electrical shock andpossible death.
Follow the recommendations made by
theNational Electrical Code for
grounding.
1. Allgrounded, cord connected tools:
In theevent of amalfunction or breakdown, grounding
provides apath of least resistance for electric current
to reduce therisk of electric shock.This tool is
equipped with an electric cord having an equipment-
grounding conductor andagrounding plug. Theplug
must be plugged into amatching outlet that is prop-
erly installed and grounded in accordance with all lo-
calcodes andordinances. Do notmodify theplug
provided -if it will notfittheoutlet, have theproper
outlet installed by aqualified electrician.
Improper connection of theequipment-grounding con-
ductor canresult in arisk of electric shock. Thecon-
ductor with insulationhaving an outer surface thatis
green, with or without yellow stripes, is theequip-
ment-grounding conductor. If repairor replacement
of theelectric cord or plug is necessary, do not
connect theequipment-grounding conductor to alive
terminal. Check with aqualified electrician or
service personnel if thegrounding instructions are
notcompletely understood, or if in doubtas to
whether thetool is properly grounded.
Useonly3-wire extension cords thathave 3-
prong grounding plugs and3-pole receptacles that
accept thetool’splug.
Repair or replace damaged or worn cord immediately
2. Grounded, cord-connected tools intended foruse
on asupply circuit having anominal rating less than
150 volts:
This toolis intended foruseon acircuit that hasan
outlet that looks like theoneillustrated in Sketch A,
Figure 8. Thetoolhasagrounding plug thatlooks
like theplug illustrated in Sketch A.
Atemporary adapter, which looks like theadapter il-
lustrated in Sketches BandCin Figure 8, maybe
used to connect this plug to a2-polereceptacle as
shown in Sketch Bif aproperly grounded outlet is not
available. Thetemporary adaptershould be used only
until aproperly grounded outlet canbe installed by a
qualified electrician. Thegreen-colored rigidear, lug,
andthelike, extending from theadaptermust be con-
nected to a permanent ground such as aproperly
grounded outlet box.
Note: In Canada, the use of a temporary adapter is
not permitted by the Canadian Electrical Code
3. Grounded, cord-connected tools intended foruse
on asupply circuit having anominal rating between
150-250volts, inclusive:
This toolis intended foruseon acircuit that hasan
outlet thatlooks like theoneillustrated in Sketch D
Figure 8. Thetoolhasagrounding plug thatlooks
like theplug illustrated in Sketch D.
Make sure thetoolis connected to an outlet having
thesame configuration as theplug. No adapter is
available or should be used with this tool. If thetool
must be reconnected foruseon adifferent type of
electric circuit, thereconnection should be madeby
qualified service personnel andafterreconnection, the
toolshould comply with alllocal codes andordinances.
EXTENSION CORDS
Useproper extension cord. Makesure your exten-
sion cord is in good condition. When using an exten-
sioncord, be sure to useoneheavy enough to carry
thecurrent your product will draw. An undersized cord
will cause adrop in linevoltage resulting in loss of
power andoverheating. Figure 9shows thecorrect
size to use depending on cord length and nameplate
ampererating. If in doubt, usethenextheavier gauge.
The smaller the gauge number, the heavier the cord.
REWIRING MOTOR FOR 230 VOLTS
When rewiring thesupplied electric motorfor230volts,
be sure power cord is unplugged thenchange the
connections as illustrated in the diagram in the motor
wiring box. Always secure wire nuts with friction tape.
Anew plug will be required for 230 volts as illustrated in
Figure 8, Sketch D.
