MANTA I
Revision 03/05, Effective Date March 2, 2005
The MK-Manta I Core Drill rig has been equipped with either a 20 Amp/115V 3
speed motor, a 20 Amp/120V 2 speed motor, or a 15 Amp/115V 2 speed motor.
The drill should be used on an electrical circuit, separate from other loads, and
protected by a 30 amp circuit breaker.
The MK-Manta I has been provided with a 20 Amp plug (NEMA 15-20) or a 30
Amp (NEMA 15-30) locking plug depending on the model.
The MK Manta is marked “Grounding Required” and has a three wire cord and
three prong grounding plug. The plug must be connected to a properly grounded
outlet (see figure below). If the tool should electrically malfunction or break
down, grounding provides a low resistance path to carry electricity away from
the user, reducing the risk of electrical shock.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding systems and must never be attached
to an electrically live terminal.
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the figure to the left.
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet
is properly grounded. Do not modify the plug provided with the tool. Never
remove the grounding prong from the plug. Do not use the tool if the cord or
plug is damaged. If damaged, have it repaired by an authorized service facility
before use. If the plug will not fit the outlet, have a proper outlet installed by a
qualified electrician. The use of a circuit protected by a ground fault interrupter
(GFI) is highly recommended.
Use extension cords of the proper cable size, referring to the following chart.
Cord Length 25 feet 50 feet 75 feet
Wire Size (AWG) #10 #8 #6
Never use an extension cord smaller than shown in the chart. Be sure your
extension cord is properly wired and in good electrical condition. Always replace
a damaged extension cord or have it repaired by a qualified electrician before
using it.
Protect your extension cords form sharp objects, excessive heat and damp or
wet areas.
Notice: Using an extension cord with inadequately sized wire causes a serious
drop in voltage, resulting in loss of power and possible tool damage.
