Plug the cord from the motor into the upper outlet on the meter box (the one opposite the motor on-off
switch). The other outlet on the meter box is for use with the vacuum pump.
The MK-Manta III Core Drill rig has been equipped with a Milwaukee 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 III Core Drill 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 III Core Drill 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 toll’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.
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 (GFCI) is highly recommended.
Use extension cords of the proper cable size, referring to the following chart.
DRILLING OPERATIONS
Improperly connecting the grounding wire can result in the risk of elec-
tric shock. Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. Do not modify the plug pro-
vided with the tool. Never remove the grounding prong from the plug.
