direction opposite of the accessory’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump toward or away
from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by taking
proper precautions as given below.
a) Maintain a firm grip on the power tool and position your
body and arm to allow you to resist kickback forces. Always
use auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up. The operator can
control torque reactions or kickback forces, if proper precautions
are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in the area where power tool will
move if kickback occurs. Kickback will propel the tool in
direction opposite to the wheel’s movement at the point of
snagging.
d) Use special care when working corners, sharp edges etc.
Avoid bouncing and snagging the accessory. Corners, sharp
edges or bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
e) Do not attach a saw chain, woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss of
control.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
a) Use only wheel types that are recommended for your
power tool and the specific guard designed for the selected
wheel.
Wheels for which the power tool was not designed cannot
be adequately guarded and are unsafe.
b) The guard must be securely attached to the power tool and
positioned for maximum safety, so the least amount of wheel
is exposed towards the operator. The guard helps to protect
operator from broken wheel fragments and accidental contact with
wheel.
c) Wheels must be used only for recommended applications.
For example: do not grind with the side of cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them to shatter.
d) Always use undamaged wheel flanges that are of correct
size and shape for your selected wheel. Proper wheel flanges
support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from grinding wheel
flanges.
e) Do not use worn down wheels from larger power tools.
Wheel intended for larger power tool is not suitable for the higher
speed of a smaller tool and may burst.
Additional Safety Warnings Specific for Abrasive Cutting-Off
Operations:
a) Do not “jam” the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut and the possibility of
kickback or wheel breakage.
b) Do not position your body in line with and behind the
rotating wheel. When the wheel, at the point of operation, is
moving away from your body, the possible kickback may propel
the spinning wheel and the power tool directly at you.
c) When wheel is binding or when interrupting a cut for any
reason, switch off the power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the cut while the
wheel is in motion otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let
the wheel reach full speed and carefully reenter the cut. The
wheel may bind, walk up or kickback if the power tool is restarted
in the workpiece.
e) Support panels or any oversized workpiece to minimize the
risk of wheel pinching and kickback. 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.
f) 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 kickback.
Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires by
applying excessive load to the brush. The wire bristles can
easily penetrate light clothing and/or skin.
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.
Dust and splinters must not be removed while the machine is
running.
Never reach into the danger area of the tool when it is running.
Always use the auxiliary handle.
Always use the protecting cap when roughing-down and
separating.
Immediately switch off the machine in case of considerable
vibrations or if other malfunctions occur. Check the machine in
order to find out the cause.
Always use and store the grinding disks according to the
manufacturer's instructions.
When grinding metal, flying sparks are produced. Take care that
no persons are endangered. Because of the danger of fire, no
combustible materials should be located in the vicinity (spark flight
zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust flying
from the workpiece come into contact with you.
The adjusting nut must be tightened before starting to work with
the machine.
The workpiece must be fixed if it is not heavy enough to be
steady. Never lead the workpiece to the grinding disk with your
hand.
For accessories intended to be fitted with threaded hole wheel,
ensure that the thread in the wheel is long enough to accept the
spindle length.
For cutting or separating use a closed protection cap, available as
an accessory.
Do not dispose of used battery packs in the household refuse or
by burning them. Your power tool distributor will normally retrieve
old batteries to protect our environment.
Use only System Berner chargers for charging System Berner
battery packs. Do not use battery packs from other systems.
Do not store the battery pack together with metal objects (short
circuit risk).
Never break open battery packs and chargers and store only in
dry rooms. Keep dry at all times.
Battery acid may leak from damaged batteries under extreme load
or extreme temperatures. In case of contact with battery acid
wash it off immediately with soap and water. In case of eye
contact rinse thoroughly for at least 10 minutes and immediately
seek medical attention.
SPECIFIED CONDITIONS OF USE
The angle grinder may be used for cutting-off, grinding and wire
brushing a wide range of materials, such as metal or stone. If you
have any doubts, please refer to the instructions supplied by the
accessory manufacturer.
Do not use this product in any other way as stated for normal use.

BATTERIES
New battery packs reach full loading capacity after 4 - 5 chargings
and dischargings. Battery packs which have not been used for
some time should be 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, after use, the battery packs have to be
fully charged.
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.
Discharge lithium ion battery packs before disposing them. Isolate
poles to avoid short circuits.
Lithium Ion batteries submit only discharged at the collection
points. Pole isolated to avoid short circuits.
MAINTENANCE
The ventilation slots of the machine must be kept clear at all
times.
Do not let any metal parts reach the airing slots - danger of short
circuit!
Use only Berner accessories and spare parts. Should components
need to be replaced which have not been described, please
contact one of our Berner service agents (see our list of
guarantee/service addresses).
If needed, an exploded view of the tool can be ordered. Please
state the ten-digit No. as well as the machine type printed on the
label and order the drawing at Berner.
