NOTICE:

ATTENTION:

The MK-130/3 is designed for wet drilling in concrete and stone using diamond core bits. For drilling

diameters bigger than 1-1/2” using 1st or 2nd speed, use a suitable drill stand.

In hand held drilling operations, only use the MK 130/3 with the enclosed auxiliary handle. This handle

must be tightened on the collar by turning the handle.

The MK-130/3 machine has class 1 protection. For operator protection this machine must only be

used with a GFCI.

Check that the voltage and frequency available are compatible with the drive motor. A ± 5% voltage

difference is allowed. For protection purposes the machine is equipped with a integrated GFCI switch

for the direct connection to a grounded socket. Check the GFCI before using the machine (please

read the separate instructions).

Choose the proper gear and speed according to the drill bit size used. To switch gears, turn drill

spindle by hand until gears mesh/align.

Use only a 3-wire extension cable with grounding conductor and sufcient cross-section (12 gauge

min.). A cross-section which is too small could lead to excessive voltage drop and to overheating the

motor and the cable.

Don’t use the GFCI-switch for switching the machine ON/OFF.

Switch only when the machine is stopped and turned OFF.

Hand Drilling in 1st gear is strongly not recommended as the high torque created

can be extremely dangerous and cause injury.
