
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted
in the workpiece.
 Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge
of the workpiece on both sides of the wheel.
 Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kick-
back.
Additional safety warnings
Wear safety goggles.
 Use appropriate detectors to determine if util-
ity lines are hidden in the work area or call the
local utility company for assistance. Contact
with electric lines can lead to fire and electric
shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property
damage.
 Release the On/Off switch and set it to the off
position when the power supply is interrupted,
e.g. when the battery pack is removed.
 Do not touch grinding and cutting discs before
they have cooled down. The discs can become
very hot while working.
 Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
 Do not open the battery. Danger of short-circuit-
ing.
Protect the battery against heat, e. g.,
against continuous intense sunlight,
fire, water, and moisture. Danger of ex-
plosion.
 In case of damage and improper use of the
battery, vapours may be emitted. Ventilate the
area and seek medical help in case of com-
plaints. The vapours can irritate the respiratory
system.
 Use the battery only in conjunction with your
Berner product. This measure alone protects
the battery against dangerous overload.

The battery can be damaged by pointed ob-
jects such as nails or screwdrivers or by force
applied externally. An internal short circuit can
occur and the battery can burn, smoke, explode
or overheat.
