You must recharge the battery pack when you
notice that the performance of the device drops.
Never allow the battery pack to become fully di-
scharged. This will cause it to develop a defect.
6.2 Switch (Fig. 4)
The angle grinder comes with a safety switch
which is designed to prevent accidents. To switch
on, push the On/O
ff
switch (2) to the right and
then forwards. To switch o
ff
the angle grinder,
depress the On/O
ff
switch (2) at the back. The
On/O
ff
switch (2) will jump back into its starting
position.
Wait until the machine has reached its top
speed. You can then position the angle grin-
der on the workpiece and machine it.
6.3 Battery capacity indicator (Fig. 6 – Item 2)
Press the battery capacity indicator switch (a).
The battery capacity indicator (2) shows the char-
ge status of the battery using 3 LEDs.
All 3 LEDs are lit:
The battery is fully charged.
2 or 1 LED(s) are lit:
The battery has an adequate remaining charge.
1 LED blinks:
The battery is empty, recharge the battery.
All LEDs blink:
The battery pack has undergone exhaustive di-
scharge and is defective. Do not use or charge a
defective battery pack.
6.4 Changing the grinding wheels (Fig. 5)
Warning!
•
Simple wheel change by spindle lock:
•
Press the spindle lock and allow the grinding
wheel to latch in place.
•
Open the flange nut with the face spanner.
(Fig. 5)
•
Change the grinding or cutting wheel and
tighten the flange nut with the face spanner.
Notice!
Only ever press the spindle lock when the
motor and grinding spindle are at a stand-
still! You must keep the spindle lock pressed
while you change the wheel!
For grinding or cutting wheels up to approx. 3 mm
thick, screw on the
fl
ange nut with the
fl
at side
facing the grinding or cutting wheel.

6.6 Motor
It is vital for the motor to be well ventilated during
operation. Be sure, therefore, to keep the ventilati-
on holes clean at all times.
6.7 Grinding Wheels
•
Never use a grinding or cutting wheel bigger
than the specified diameter.
•
Before using a grinding or cutting wheel,
check its rated speed.
•
The maximum speed of the grinding or cut-
ting wheel used must be higher than the idle
speed of the angle grinder.
•
Use only grinding and cutting wheels that are
approved for a minimum speed of 8,500 rpm
and a peripheral speed of 52 m/sec.
•
Check the direction of rotation when you use
diamond cutting wheels. The directional arrow
on the diamond cutting wheel must point in
the direction in which the tool rotates.
Take special care that the grinding/sanding
wheels are properly stored and transported.
Ensure that the grinding/sanding wheels are
never exposed to shock, jolts or sharp edges (for
example during transport or storage in a toolbox).
This could cause damage (such as cracks) to the
grinding/sanding wheels and place the user in
serious danger.
