significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Fitting
Charging the battery
u Use only the chargers listed in the technical data. Only
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
u Do not continue to press the On/Off switch after the
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the battery
To remove the battery (6), press the battery unlocking but-
ton (8) and pull the battery out of the power tool. Do not ex-
ert any force.
Charge-control Indicator
The charge-control indicator (5) displays the charge condi-
tion of the battery for several seconds when the On/Off
switch (4) is half-pressed or fully pressed. It consists of 3
green LEDs.
LED Capacity
Continuous lighting 3x green ≥ 66%
Continuous lighting 2x green 33–66%
Continuous lighting 1x green 11–33%
Slowly flashing light 1 x green ≤ 10%
The 3 LEDs in the charge-control indicator flash quickly
when the temperature of the battery is outside of the op-
erating temperature range of –30 to +65 °C and/or the
overload protection has been triggered.
Fitting Protective Equipment
u Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Note: If the grinding disc breaks during operation or the
holding fixtures on the protective guard/power tool become
damaged, the power tool must be sent to the after-sales ser-
vice immediately; see the "After-Sales Service and Applica-
tion Service" section for addresses.
Protective guard for grinding
Place the protective guard
(10) onto the holder on the
power tool until the coding
cams of the protective
guard are aligned with the
holder. When doing so,
press and hold the unlock-
ing lever (1).
Press the protective guard
(10) onto the spindle collar
until the shoulder of the
protective guard is sitting
on the flange of the power
tool and rotate the protect-
ive guard until it audibly
clicks into place.
Adjust the position of the protective guard (10) to meet the
requirements of the operation. To do this, push the unlock-
ing lever (1) upward and rotate the protective guard (10)
into the required position.
u Always position the protective guard (10) such that all
three red cams on the unlocking lever (1) engage in
the corresponding openings on the protective guard
(10).
u Adjust the protective guard (10) such that sparking in
the direction of the operator is prevented.
u The protective guard (10) must only be adjustable
while the unlocking lever (1) is actuated. Otherwise,
the power tool must not be used any more under any
circumstances and must be sent to the after-sales ser-
vice.
Note: The coding cams on the protective guard (10) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Protective guard for cutting
u Always use the protective guard for cutting (13) when
cutting bonded abrasives.
u Provide sufficient dust extraction when cutting stone.
The protective guard for cutting (13) is fitted in the same
way as the protective guard for grinding (10).
