b) If the use of a guard is recommended for wire brushing, do
not allow any interference of the wire wheel or brush with the
guard. Wire wheel or brush may expand in diameter due to work
load and centrifugal forces.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Always check if the spindle lock button is fully released before
switching on the tool! After using the spindle lock to tighten / loosen
the abrasive disc, it is possible that the button may stick in the lock
position.
When grinding metal, fl ying sparks are produced. Take care that
no persons are endangered. Because of the danger of fi re, no
combustible materials should be located in the vicinity (spark fl ight
zone). Do not use dust extraction.
Avoid fl ying sparks and sanding dust hit your body.
Never reach into the danger area of the machine when it is running.
Chips and splinters must not be removed while the machine is running.
Immediately switch off the machine in case of considerable vibrations
or if other malfunctions occur. Check the machine in order to fi nd out
the cause.
Under extreme conditions (e.g. smooth-grinding metals with the arbour
and vulcanized fi bre grinding wheel), signifi cant contamination can
build up on the inside of the die grinder.
Do not let any metal parts enter the airing slots - danger of short circuit!
WARNING! Danger of burns! The wheel and workpiece will become
hot during use. Wear gloves when changing discs or touching
workpiece. Keep hands away from the grinding area at all times.
WARNING! To reduce the risk of fi re, personal injury, and product
damage due to a short circuit, never immerse your tool, battery pack
or charger in fl uid or allow a fl uid to fl ow inside them. Corrosive or
conductive fl uids, such as seawater, certain industrial chemicals, and
bleach or bleach containing products, etc., Can cause a short circuit.
Never break open battery packs and chargers and store only in dry
rooms. Keep dry at all times.
Use only System Berner chargers for charging System Berner battery
packs. Do not use battery packs from other systems.

NOTES FOR LI-ION BATTERIES
Use of Li-Ion batteries
Battery packs which have not been used for some time should be
ENGLISH

recharged before use.
Temperatures in excess of 50°C (122°F) reduce the performance of
the battery pack. Avoid extended exposure to heat or sunshine (risk of
overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum life-time, the battery packs have to be fully charged,
after use.
To obtain the longest possible battery life remove the battery pack from
the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C and away
from moisture
Store the battery packs in a 30% - 50% charged condition
Every six months of storage, charge the pack as normal.
Battery protection for Li-Ion batteries
In extremely high torque, binding, stalling and short circuit situations
that cause high current draw, the tool will vibrate for about 5 seconds,
the fuel gauge will fl ash,and then the tool will turn OFF.
To reset, release the trigger. Under extreme circumstances, the
internal temperature of the battery pack could raise too much. If this
happens, the fuel gauge will fl ash until the battery pack cooled down.
After the lights go off , the work may continue.
Transporting Lithium Batteries
Lithium-ion batteries are subject to the Dangerous Goods Legislation
requirements.
Transportation of those batteries has to be done in accordance with
local, national and international provisions and regulations.
The user can transport the batteries by road without further
requirements.
Commercial transport of Lithium-Ion batteries by third parties is subject
to Dangerous Goods regulations. Transport preparation and transport
are exclusively to be carried out by appropriately trained persons and
the process has to be accompanied by corresponding experts.
When transporting batteries:
Ensure that battery contact terminals are protected and insulated to
prevent short circuit.
Ensure that battery pack is secured against movement within
packaging. Do not transport batteries that are cracked or leak. Check
with forwarding company for further advice.
WORKING INSTRUCTIONS
For accessories intended to be fi tted with threaded hole wheel, ensure
that the thread in the wheel is long enough to accept the spindle
length.
Always use and store the cutting and grinding wheels according to the
manufacturer's instructions.
Always use the correct guard for cutting and grinding.
The grinding surface of the centre depressed wheels must be mounted
min. 2 mm below the plane of the guard lip.
The adjusting nut must be tightened before starting to work with the
machine.
Always use the auxiliary handle.
The workpiece must be fi xed if it is not heavy enough to be steady.
Never move the workpiece towards the rotating wheel by hand.
The fl ange nut must be securely tightened before the machine is
started. If the tool is not securely tightened with the fl ange nut, it is
possible that the tool will lose the required clamping force when it is
decelerated.
OVERLOAD AND KICKBACK PROTECTION
The power tool has an overload and kickback safety function and stops
if it is overloaded. Switch off the power tool and then switch the power
tool back on again in order to continue to work.
SOFT START
Electronic soft start for save use prevents jerky run-up of the machine.
