Intended Use
The machine is intended for cutting, roughing, grinding
and brushing of metal materials, as well as for working
stone. The machine is not intended for working with dia-
mond cutting heads.
For damage caused by usage other then intended, the
user is responsible.
Before Putting into Operation
The batteries are partially charged and delivered in idle
EWS 28-A
state. The battery must be activated before using for the
0700 237 X
first time. For this, place the battery onto the charger for
28 V
a short time. The LED 13 on the battery indicates the
charge condition (see main figure).
9 000 rpm
When the battery is not used for longer periods, it
115/125 mm
switches to the idle state. In order to use the battery
M 14
again, it must be reactivated.
2,8 kg
When the battery is completely discharged, it switches
Li-Ion
off automatically (deep discharging not possible).
0700 957 730
When the power tool is switched on nonetheless, the
NTC
battery delivers only brief current pulses. The power tool
"flickers" as an indication that the battery must be
28 V
charged.
3.0 Ah
As a general rule: Should the power tool not be opera-
1.0 kg
tive after inserting the battery, place the battery onto the
charger. The indicators on the battery and the charger
then provide information about the battery condition
(see main figure).
At low temperatures, further operation is possible with
reduced power output. The battery switches off auto-
matically below –10 °C.
Battery Charging
A battery that is new or has not been used for a longer
period does not develop its full capacity until after
approximately 2 – 3 charging/discharging cycles.
To remove the battery 10, press the unlocking buttons
12 and pull out the battery toward the rear. Do not
exert any force.
Please refer to the enclosed "Battery Charger" instruc-
tions for the operation of the battery charger as well as
for a description of the charging process.
The battery is equipped with an NTC temperature con-
trol which allows charging only within a temperature
range of between –10 °C and +66 °C. A long battery
service life is achieved in this manner.
A significantly reduced working period after charging
indicates that the batteries are used and must be
replaced.
Observe the notes on environmental protection.
Charge-control Indicator (see Main Figure)
The battery 10 is fitted with a charge-control indica-
tor 13.
By pressing the button 14, the battery charge can also
be checked when the battery has been removed, or
when the machine is at a standstill (machine must be
switched off for at least 1 minute). After approx. 4 sec-
onds the battery charge display automatically turns off.
When the first display element begins to flash (0 –
10 %) the battery is almost empty and must be
recharged.
