k) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear per-
sonal protective equipment. Fragments of workpiece or
of a broken wheel may fl y away and cause injury beyond
immediate area of operation.
l) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory
contacting a "live" wire may make exposed metal parts of
the power tool "live" and could give the operator an electric
shock.
m) Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel may
grab the surface and pull the power tool out of your control.
n) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory could
snag your clothing, pulling the accessory into your body.
o) Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
p) Do not operate the power tool near fl ammable mate-
rials. Sparks could ignite these materials.

operations
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid stalling
of the rotating wheel which in turn causes the uncontrolled
power tool to be forced in the direction opposite of the
wheel'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 fi rm 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 line with the rotating
wheel. 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 ed-
ges 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, seg-
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
f) Do not "jam" the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and suscep-
tibility to twisting or binding of the wheel in the cut and the
possibility of kickback or wheel breakage.
g) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold the
470 349 - BMMS18SBL.indd 21 470 349 - BMMS18SBL.indd 21
power tool motionless until the wheel comes to a com-
plete stop. Never attempt to remove the wheel from the
cut while the wheel is in motion otherwise kickback
may occur. Investigate and take corrective action to elimi-
nate the cause of wheel binding.
h) Do not restart the cutting operation in the workpie-
ce. Let the wheel reach full speed and carefully re-enter
the cut. The wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
i) Support panels or any oversized workpiece to mi-
nimize 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.
j) 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.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
The rated speed of the accessory must be at least equal to
the maximum speed marked on the power tool.
Accessories running faster than their rated speed can
break and fl y apart.
Use protective equipment. Always wear safety glasses
when working with the machine. The use of protective
clothing is recommended, such as dust mask, protective
gloves, sturdy non-slip footwear, helmet and ear defenders.
The dust produced when using this tool may be harmful to
health. Do not inhale the dust. Wear a suitable dust
protection mask.
Do not machine any materials that present a danger to
health (e.g. asbestos).
Switch the device off immediately if the insertion tool stalls!
Do not switch the device on again while the insertion tool is
stalled, as doing so could trigger a sudden recoil with a
high reactive force. Determine why the insertion tool stalled
and rectify this, paying heed to the safety instructions.
The possible causes may be:
• it is tilted in the workpiece to be machined
• it has pierced through the material to be machined
• the power tool is overloaded
Do not reach into the machine while it is running.
The insertion tool may become hot during use.
• when changing tools
• when setting the device down
When working in walls ceiling, or fl oor, take care to avoid
electric cables and gas or waterpipes.
Remove the battery pack before starting any work on the
machine.
Do not dispose of used battery packs in the household
refuse or by burning them. AEG Distributors off er to retrieve
old batteries to protect our environment.
Do not store the battery pack together with metal objects
(short circuit risk).
Use only System GBS chargers for charging System GBS
battery packs. Do not use battery packs from other
systems.
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.
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
