5. Electrical Part Information
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.

9. Operation
Drilling Speeds
Factors influencing the drilling sped: type of material. drilled hole size. type of bit. required quality of cut.
Remember that the smaller the bit is the larger is the required speed. When drilling soft materials. higher
speed is required than that for the hard materials (see the table of drilling specifications).
Metal Drilling
Metal pieces need to be clamped safely. some of our vices are recommended. Never hold the piece just with
hands. The bit cutting edges may catch the piece and cause a serious injury to you. The bit will get broken
when a metal object strikes against the column. .
The piece to be drilled should be firmly clamped. Any tilting. twisting and shifting will result in a rough drilled
hole and the risk of breaking the bit will increase as well. If the metal object is flat. underlay it with a piece of
wood to prevent spinning. If the shape is irregular and its area cannot lie on the bench entirely. it should be
fixed.
Wood Drilling
It is possible to use the metal working bits for wood working as well. however. wood drilling bits should be
preferred. Do not use twist drills. those rotate so fast that they will lift the drilled piece from the bench and will
spin it around. To drill the material through. the bench has to be aligned for the bit to get in the centre hole.
When the bit starts cutting wood. the advance should add gradually to prevent the material from shattering.
Put a piece of waste wood under the worked material as a pad. It will help to reduce the shattering qualities
and protect the drill bit tip.
Advancement
Apply sufficient force on the advancement hand lever to press it down. interrupt the advancement now and
then to keep the chips short or to direct the sawdust from the hole being drilled. Too fast advancement could
result in the motor stopping. belt slipping. damaging the piece being drilled or breaking the bit. Too slow
advancement could heat the drilling bit and the piece being drilled could get burnt.
10. Maintenance
WARNING: SWITCH OVER TO “OFF” POSITION AND UNPLUG THE MACHINE BEFORE
MAINTENANCE OR LUBRICATION OF THE MACHINE FOR YOU TO BE SAFE.
Blow off or suck off any sawdust and chips gather on the motor. pulley housing. bench and the drilled piece
surface.
Wipe the gloss surface with an oiled cloth.
Apply a layer of pasty wax on the column and the bench to keep the surfaces clean with any spots of rust.
The ball bearings in the pinion and v-belt pulley assembly are lubricated for life and sealed permanently. Pull
the pinion down and lubricate with oil on a three-month basis.
If the bench clamping devices and locking knobs run heavily. lubricate them.
CAUTION: Any routine and scheduled maintenance of the drill should be done by an authorised
servicing technician.
