Power Source; Grounding Instructions - PowerTec OS1000 Owner's Manual

POWER SOURCE

WARNING
Do not connect to the power source until the machine is
completely assembled.
The machine is wired for 120 volts, 60 HZ alternating
current. 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
4
voltage specified on nameplate.
• Power supply to the motor is controlled by a single pole
locking rocker switch. Remove the key to prevent
unauthorized use.

GROUNDING INSTRUCTIONS

WARNING
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 150V and a 3-prong
grounding type plug (Figure 6) 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 6)
• 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 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

WARNING
Do not permit fingers to touch the terminals of plug when
installing or removing from outlet.
• Inspect tool cords periodically, and if damaged, have
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 7) may be used to connect this plug to a matching
2-conductor receptacle as shown in figure 7. The tempo-
rary adapter should be used only until a properly grounded
outlet can be installed by a qualified electrician.

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 ground,
grounding means must be tested by a qualified
electrician.
