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
voltage specified on nameplate.
• Power supply to the motor is controlled by a 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.
Switch
• 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 for your protection against
shock hazards.
• Grounding plug should be plugged directly into a
properly installed and grounded 3-prong grounding-type
receptacle.
• 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
Figure 17.

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 18) may be used to connect this plug to a matching
2-conductor receptacle. The temporary adapter should be
used only until a properly grounded outlet can be installed
by a qualified electrician.
