determined according to EN60745:
Work mode : polishing
Vibration emission (ah,P) : 2.5 m/s2or less
Uncertainty (K) : 1.5 m/s2
ENG902-1
• The declared vibration emission value has been
measured in accordance with the standard test
method and may be used for comparing one tool
with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
• The declared vibration emission value is used for
main applications of the power tool. However if the
power tool is used for other applications, the
vibration emission value may be different.
WARNING:
• The vibration emission during actual use of the
power tool can differ from the declared emission
value depending on the ways in which the tool is
used.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it
is running idle in addition to the trigger time).

Save all warnings and instructions for
future reference.
GEB038-3
POLISHER SAFETY WARNINGS
Safety Warnings Common for Polishing Operation:
1. This power tool is intended to function as a
polisher. Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow
all instructions listed below may result in electric
shock, fire and/or serious injury.
2. Operations such as grinding, sanding, wire
brushing or cutting-off are not recommended
to be performed with this power tool.
Operations for which the power tool was not
designed may create a hazard and cause
personal injury.
3. Do not use accessories which are not
specifically designed and recommended by
the tool manufacturer. Just because the
accessory can be attached to your power tool, it
does not assure safe operation.
4. 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 fly apart.
5. The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately guarded or
controlled.
6. Threaded mounting of accessories must
match the tool 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 control.
7. Do not use a damaged accessory. Before each
use inspect the accessory such as backing
pad for cracks, tear or excess wear. If power
tool or accessory is dropped, inspect for
damage or install an undamaged accessory.
After inspecting and installing an accessory,
position yourself and bystanders away from
the plane of the rotating accessory and run
the power tool at maximum no-load speed for
one minute. Damaged accessories will normally
break apart during this test time.
8. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As
appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments. The eye protection must
be capable of stopping flying debris generated 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.
9. 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.
10. Position the cord clear of the spinning
accessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning accessory.
11. Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull
the power tool out of your control.
12. 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.

6
13. 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.
14. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
15. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating 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 accessory’s rotation at the point of the
binding.
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 Polishing Operations:
a) Do not allow any loose portion of the
polishing bonnet or its attachment strings to
spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning
attachment strings can entangle your fingers or
snag on the workpiece.
Additional safety warnings:
16. Do not leave the tool running. Operate the tool
only when hand-held.
17. Check that the workpiece is properly
supported.
18. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure
operator safety.
19. Do not use the tool on any materials
containing asbestos.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.
