Grounding Instructions
IN CASE OF FAULT OR OUTAGE, grounding guarantees the current the least resistance passage and
reduces the risk of electrical shock. This machine has a power cable fitted with grounding conductor and
grounding plug.
The plug MUST be inserted in the interconnecting socket conforming to ANY local regulations and properly
installed and grounded in compliance with the same.
DO NOT ALTER THE PLUG SUPPLIED IN ANY WAY. If it does not fit in your socket, have a matching socket
installed by a qualified electrician.
UNQUALIFIED CONNECTION of the grounding conductor may entail a risk of electrical shock. The green-
insulated conductor (with/without yellow stripes) is the grounding conductor. If repair or replacement of the
power cable or the plug is required, DO NOT CONNECT the grounding conductor to the conductive input
terminal.
If you do not quite understand grounding instruction or if you are not sure that the machine is grounded as
appropriate, invite a qualified electrician or a servicing staff to CHECK the grounding conductors.
CAUTION: IF IN DOUBT ON YOUR SOCKET APPROPRIATENESS, MAKE SURE THAT IT IS GROUNDED
AS REQUIRED. IF YOU ARE NOT SURE, HAVE IT CHECKED BY A QUALIFIED ELECTRICIAN.
WARNING: THIS DRILLING MACHINE IS DESIGNED FOR WORKING INDOORS ONLY. NEVER EXPOSE
IT TO RAIN AND DO NOT USE IT IN ANY WET AREAS.
WARNING: THE MACHINE IS PERMITTED FOR OPERATION PROVIDED THAT IT IS CONNECTED TO A
VOLTAGE SOURCE USING A FAULT CURRENT PROTECTION SWITCH.
Make sure that the extension cable working condition is good. Provided that an extension cable be used,
make sure that the cross-section of it is sufficient for it to conduct the current needed for the product. An
undersized extension cable will cause a voltage drop resulting in the current loss and overheating. The table
below shows the correct sizes to be used subject to the cable length and the current value shown on the plate.
If in doubt, use the nearest bigger size.
The extension cable sizes show in the table will provide against a voltage drop above 5% at an estimated
load.
