PowerTec AF4000 - Power Source Connection; Grounding Instructions; Extension Cord Guidelines

POWER SOURCE
Do not connect to the power source until the machine is
completely assembled.
The machine is wired for 120 volts, 60 HZ alternating cur-
rent. Before connecting the machine to the power source,
makesuretheswitchisinthe“OFF”position.Running
the unit on voltages which are not within range may cause
overheating and motor burn-out. Heavy loads require that
voltage at motor terminals be no less than the voltage
specified on nameplate.
GROUNDING INSTRUCTIONS
Improper connection of equipment grounding conductor
can result in the risk of electrical shock.
• Themachineshouldbegroundedwhileinusetoprotect
operator from electrical shock.
•Intheeventofanelectricalshortcircuit,grounding 
reduces the risk of electrical shock by providing an
escape wire for the electric current.
•Thismachineisequippedwithanapproved3-conductor
cord rated at 120V and a 3-prong grounding type plug
for your protection against shock hazards.
•Groundingplugshouldbepluggeddirectlyintoa 
properly installed and grounded 3-prong grounding-type
receptacle, as shown (Figure 5).
•Theplugmustbepluggedintoanoutletthatisproperly
installed and grounded in accordance with all local
codes and ordinances.
•Checkwithaqualifiedelectricianorservicepersonnel
if these instructions are not completely understood or if
in doubt as to whether the tool is properly grounded.
•Donotmodifyplugprovided.Ifitwillnotfitinoutlet, 
Have a proper outlet installed by a qualified electrician.
Use only 3-wire extension cords, that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as show in
Figure 6.
Figure 5 - 3-Prong Receptacle
Do not permit fingers to touch the terminals of plug when
installing or removing from outlet.
•Inspecttoolcordsperiodically,andifdamaged,haveit
repaired by an authorized service facility.
•Theconductorwithinsulationhavinganoutersurface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary,
do not connect the green (or green and yellow) wire to a
live terminal.
• Atemporary3-prongto2-pronggroundingadapter(see
Figure 6) may be used to connect this plug to a
matching 2-conductor receptacle as shown in figure 6.
The temporary adapter should be used only until a
properly grounded outlet can be installed by a qualified
electrician.
Figure 6 - 2-Prong Receptacle
In Canada, the use of temporary adapter is not permitted
bytheCanadianElectricCode.Wherepermitted,therigid
green tab or terminal on the side of the adapter must be
securely connected to a permanent electrical ground such
as a properly grounded water pipe, a properly grounded
outlet box or a properly grounded wire system.
• Manycoverplatescrews,waterpipesandoutletboxes
are not properly grounded. To ensure proper grounding
means that it must be tested by a qualified electrician.
EXTENSION CORDS
Use proper extension cords. Make sure the extension cord
is in good condition. Use only 3-wire extension cords that
have 3-prong grounding type plugs and 3-pole receptacles
whichacceptthetoolplug.Whenusinganextensioncord,
make sure to use one heavy enough to carry the current of
the machine. An undersized cord will cause a drop in the
voltage, resulting in loss of power and overheating. Use
thetabletodeterminetheminimumwiresize(A.W.G.)
extension cord.
