Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1. Work area safety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases
or dust. Power tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2. Electrical safety
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock
if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges and moving
parts. Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
3. Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do not
use a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in
serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal
c) Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites
F 000 622 340 | 06.2011
d) Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long hair
can be caught in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
h) Use ear protectors. Exposure to noise can cause hearing
4. Power tool use and care
a) Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
b) Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
g) Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
5. Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
b) In case of consuming of the carbon brushes to send
the tool by assistance authorized technique for
substitution. Carbon brushes are of specify them cause
damages to the motor of the tool.

c) If the power cord is damaged, the power cord shall be
replaced by manufacturer, service or qualified person to
avoid the risk of electrical shock.
Safety Warnings for Sander
►► Use the machine only for dry sanding. Penetration of
water into the machine increases the risk of an electric
►► Caution, fire hazard! Avoid overheating the
object being sanded as well as the sander. Always
empty the dust collector before taking breaks. In
unfavourable conditions, e. g., when sparks emit from
sanding metals, sanding debris in the dust bag, micro
filter or paper sack (or in the filter sack or filter of the
vacuum cleaner) can self-ignite. Particularly when
mixed with remainders of varnish, polyurethane or other
chemical materials and when the sanding debris is hot
after long periods of working.
►► Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than
by hand.
Products sold in GB only: Your product is fitted with an
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should
be cut off and an appropriate plug fitted in its place by an
authorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
Products sold in AUS and NZ only: Use a residual current
device (RCD) with a rated residual current of 30 mA or less.

The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool
with another.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main
applications of the tool. However if the tool is used for
different applications, with different accessories or poorly
maintained, the vibration emission may differ. This may
significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should
also take into account the times when the tool is switched
off or when it is running but not actually doing the job. This
may significantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and
the accessories, keep the hands warm, organisation of work

Dust/Chip Extraction
uu Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can
cause allergic reactions and/or lead to respiratory
infections of the user or bystanders. Certain dusts, such
as oak or beech dust, are considered as carcinogenic,
especially in connection with wood-treatment additives
(chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system
suitable for the material.
