 Use power tools only with specifically designated bat-
tery packs. Use of any other battery packs may create a
risk of injury and fire.
 When battery pack is not in use, keep it away from oth-
er metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
 Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally oc-
curs, flush with water. If liquid contacts eyes, addition-
ally seek medical help. Liquid ejected from the battery
may cause irritation or burns.
Service
 Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.

Safety Warnings for Sander

Safety Warnings common for Grinding and Abrasive
Cutting Off Operations
 This power tool is intended to function as a grinder and
cutting-off machine. Read all safety warnings, instruc-
tions, illustrations and specifications provided with
this power tool. Failure to follow all instructions listed be-
low may result in electric shock, fire and/or serious injury.
 Operations such as sanding, wire brushing or polishing
are not recommended to be performed with this power
tool. Operations for which the power tool was not de-
signed may create a hazard and cause personal injury.
 Do not use accessories which are not specifically de-
signed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
 The rated speed of the accessory must be at least equal
to the maximum speed marked on the power tool. Ac-
cessories running faster than their rated speed can break
and fly apart.
 The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
 Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted by
flanges, the arbour hole of the accessory must fit the
locating diameter of the flange. Accessories that do not
match the mounting hardware of the power tool will run out
of balance, vibrate excessively and may cause loss of con-
trol.
 Do not use a damaged accessory. Before each use in-
spect the accessory such as abrasive wheels for chips
and cracks, backing pad for cracks, tear or excess
wear, wire brush for loose or cracked wires. If power
tool or accessory is dropped, inspect for damage or in-
stall an undamaged accessory. After inspecting and in-
stalling an accessory, position yourself and bystanders
1 609 92A 29F | (21.7.16)
away from the plane of the rotating accessory and run
the power tool at maximum no-load speed for one min-
ute. Damaged accessories will normally break apart during
this test time.
 Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris gen-
erated by various operations. The dust mask or respirator
must be capable of filtrating particles generated by your
operation. Prolonged exposure to high intensity noise may
cause hearing loss.
 Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a
broken accessory may fly away and cause injury beyond
immediate area of operation.
 Hold power tool by insulated gripping surfaces only,
when performing an operation where the cutting ac-
cessory may contact hidden wiring. Cutting accessory
contacting a "live" wire may make exposed metal parts of
the power tool "live" and shock the operator.
 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.
 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.
 Regularly clean the power tool's air vents. The motor's
fan will draw the dust inside the housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.
 Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
 Do not use accessories that require liquid coolants. Us-
ing water or other liquid coolants may result in electrocu-
tion or shock.
Kickback and related warnings
 Kickback is a sudden reaction to a pinched or snagged ro-
tating wheel, backing pad, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the accesso-
ry'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 pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.
