CONNECTING BORING MACHINE
TO POWER SOURCE
A separate electrical circuit should be used for your boring machine. This circuit should not be
less than #12 wire and should be protected with a 15 Amp time lag fuse or circuit breaker. If an
extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs
and 3-pole receptacles which accept the tool’s plug. For distances up to 150 feet use #10 wire.
Have a certified electrician replace or repair damaged or worn cords immediately. Before
connecting the power cord to the electrical outlet, make sure the machine switch is in the “OFF”
position and be sure that the electric current is of the same characteristics as the motor. Running
on voltage other than specified will injure the motor.
GROUNDING INSTRUCTIONS
CAUTION: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR
FROM ELECTRIC SHOCK.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. The motor and machine are equipped with
electric cords having equipment grounding conductors and grounding plugs. The plugs must be
plugged into a matching outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have a proper outlet installed by a
qualified electrician.
Improper connections of the equipment-grounding conductor can result in risk of electric shock.
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 cords or plugs are
necessary, do not connect the equipment grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded. Use only 3-wire
extension cords that have 3-pronged grounding type plugs and 3-hole receptacles that accept
the tool’s plug, as shown in Fig. 13.
Repair or replace damaged or worn cord immediately.
230 VOLT OPERATION
The motor on your machine is wired for 230 volts; the
power cord is equipped with a plug that has two flat,
current-carrying prongs in tandem, and one round or “U”
shaped longer ground prong. This is used only with the
proper mating 3-conductor grounding type receptacle,
as shown in Fig. 13.
When the 230 Volt three prong plug on your machine is
plugged into a grounded 3-conductor receptacle, the
long ground prong on the plug contacts first so the
machine is properly grounded before electricity reaches
it.
WARNING: IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A CERTI-
FIED ELECTRICIAN CHECK THE RECEPTACLE.
