Original operating instructions
MH25V
GB
the suitable speed is set depending on the diameter of the drill,
the pressure must only be such that the drill can cut without load,
if there is too much pressure, the drill will wear quickly and may even break or jam in the
borehole. If the drill jams, immediately stop the main motor by pressing the emergency stop
button,
use commercial cooling/lubricating agents for hard materials, e.g. steel and
generally always back the spindle out of the workpiece while it is still turning.
ATTENTION!
Do not use the drill chuck as a milling tool. Never clamp a milling cutter into a drill chuck. Use a
collet chuck and appropriate collets for end mills.
When milling, ensure that
the right cutting speed is selected;
for workpieces with normal strength values, e.g. steel, 18-22 m/min,
for workpieces with higher strength values 10-14 m/min,
the pressure is selected so that the cutting speed remains constant,
normal trade coolants/lubricants are used for hard materials.
INFORMATION
The MH25V milling machine is built to comply with EMC Class C2 to EN 61800-3.
WARNING!
Class C (machine tools) is not intended for use in residential buildings, in which the
power supply is provided via a public low voltage supply system. In these areas it may
possibly be difficult to guarantee electromagnetic compatibility due to lead bound as
well as emitted interferences.

Possible dangers posed by the milling machine
The milling machine was built using state-of-the-art technology.
Nevertheless, there is a residual risk, as the milling machine operates with
high speeds,
circulating parts and tools and
electrical voltage and currents.
We have used design and safety engineering to minimize the health risk to personnel resulting
from these hazards.
If the milling machine is used and maintained by personnel who are not duly qualified, there
may be a risk resulting from its incorrect or unsuitable maintenance.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified
and strictly follow these operating instructions.
Always disconnect the milling machine from the electrical power supply before performing
cleaning or maintenance tasks.
