Working instructions.
Secure the power tool with the safety strap supplied at all times, especially for
work carried out at elevated heights, when drilling horizontally or above the
head.
If there is a power loss, or the power plug is pulled out, the magnetic holding power is
not maintained.
Fastening the safety strap (figure 9).
Fasten the machine securely around the
workpiece using the provided safety strap.
For switching the magnet ON
(figure 10).
Please make sure that the contact surface-
for the magnetic base is level, clean and
rust-free. Remove any varnish or primer.
When working, always use the magnetic foot;
pay attention that the magnetic holding
power is sufficient:
Press the
Magnet
button to start the machine.
–
When the green
Magnet
button on the
control panel lights up permanently, the
magnetic holding power is sufficient and
the power tool can be operated with
man-
ual or automatic feed
.
–
When the
Magnet
button on the control
panel flashes green, the magnetic holding
power possibly is insufficient and the
power tool must be operated
manually
with reduced feed
. In this case, the KBM 50
auto may not be operated in automatic
mode.
When working on non-metal materials, suit-
able clamping devices, such as the vacuum
plate or pipe-drilling fixture, which are avail-
able as accessories, must be used.
When working on steel materials with a
material thickness less than 12 mm, the work-
piece must be enforced with an additional
steel plate in order to ensure the magnetic
holding power.
The magnetic foot is monitored by means of
a power sensor. If the magnetic foot is defec-
tive, the drill motor will not start.
