materials. It must always be mounted on a drilling stand. This machine is for professional use only and only
trained personnel may operate this machine.
All other uses which are not for the intended purpose are prohibited.
It is equipped with a water feed system which is required for the diamond core drilling process. A GFCI or PRCD
interrupter (portable residual current device)(not included) must be used at all times.
It is equipped with a three speed mechanical gearbox for different core drill size ranges and features a
mechanical safety clutch.
The motor has electronics for soft start, overload protection and thermal (overheating) protection.
The machine is equipped with spirit levels which aid in aligning the

GROUNDING INSTRUCTIONS

1.
All grounded, cord-connected tools:
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. This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug 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 the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in a 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 cord or plug is 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-prong grounding plugs and 3 pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than
300 V:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch
A. The tool has a grounding plug that looks like the plug illustrated in Sketch A. A temporary adapter,
which looks like the adapter illustrated in Sketches B and C, may be used to connect this plug to a 2-pole
receptacle as shown in Sketch B if a properly grounded outlet is not available. The temporary adapter
should be used only until a properly grounded outlet can be installed by a qualified electrician. The
green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent
ground such as a properly grounded outlet box.
