Safety
General safety instructions for power tools
Warning: Readall theinstructions.
Failure to adhere to thefollowing instructions may lead to electric shocks, fires and/or
serious injury.
SAVE THESE INSTRUCTIONS.
Theterm “power tool” in thefollowing text refers to your handheld mains operated or
battery operatedtool.
1) Work area safety
a) Keep thework area clean and well illuminated. Cluttered and poorly lit areas
invite accidents.
b) Do not use power tools in explosive environments, such as in thepresence
of flammable liquids, gases ordust. Powertools create sparks which may ignite
dust orfumes.
c) Keep children and other bystanders away from thearea where you are using
thepowertool. Distractions can cause you to lose your concentration and control.
2) Electrical safety
a) Theplug of thepower tool must fit correctly into thewall socket.
Nevermodify theplug in anyway. Neveruse anadaptor plug together with
earthed powertools. Unmodified plugs and matching outlets will reduce therisk
of electric shocks.
b) Avoid physical contact with earthed objects such as pipes, radiators, ovens
and refrigerators. Thereis anincreased risk of electric shock if your body is earthed.
c) Do not expose thepower tool to rain or other wet conditions. Waterentering
apower tool will increase therisk of electricshock.
d) Do not abuse themainslead. Neveruse thelead for carrying, pulling or
unplugging thepowertool. Keepthelead away from heat, oil, sharp edges
and movingparts. Damaged or tangled leads increase therisk of electricshock.

ENGLISH
4
e) When using power tools outdoors, use anextension lead that is suitable for
this purpose. Theuse of anextension lead designed for outdoor use decreases
therisk of electric shocks.
f) If theuse of thepower tool in awet environment is unavoidable, awall
socket equipped with aportable residual current device (PRCD) should
beused. Useof anRCD significantly reduces therisk of electricshock.
3) Personal safety
a) Pay attention to what you are doing and use common sense when using
powertools. Neveruse power tools if you are tired or under theinfluence of
drugs, alcohol or medication. Onemoment of inattention while using apower
tool may result in aserious injury.
b) Wear protective clothing. Always wear safety glasses. Usingprotective
clothing such as dust masks, non-slip safety shoes, helmets and ear defenders
decreases therisk of injury.
c) Avoid accidental starts. Makesure that thepower switch is set to OFF before
plugging thepower tool into awall socket, fitting thebattery or picking up/
carrying thepowertool. Nevercarry apower tool with your finger on thetrigger
and never connect thepower tool to awall socket when theswitch is set to ON,
since it may result in injury.
d) Remove all service tools/keys before switching on thepowertool. Aservice
tool left on 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) Wear suitable clothing. Donot wear loose-fitting clothing or jewellery.
Keephair, clothes and gloves away from movingparts. Loose-fitting clothes,
jewellery or long hair could become caught in movingparts.
g) If equipment for theextraction and collection of dust is available, make sure
it is connected and used properly. Useof dust collection equipment can reduce
dust related hazards.
4) Use and maintenance of the power tool
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 if used at therate for which
it was designed.
b) Never use thepower tool if thepower switch does not switch thetool on
and off properly. Anypower tool that cannot be controlled by thepower switch is
dangerous and must be repaired.
c) Unplug thelead from thewall socket or remove thebattery before
making any adjustments, changing accessories or storing thepowertool.
Theseprecautions reduce therisk of thepower tool starting unexpectedly.
d) Store power tools that are not being used out of children’sreach. Donot
allow people who are unfamiliar with thetool or these instructions to operate
thetool. Powertools are dangerous in thehands of untrainedusers.

ENGLISH

e) Properly maintain your powertools. Checkfor misalignment, binding of
moving parts, broken parts or anything else which might affect theoperation
of thepowertool. Ifany damage is noticed, have thepower tool repaired
beforeusing. 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, and any accessories in accordance with these
instructions, take into consideration theworking conditions and thework
that is to be performed. Use of thepower tool for apurpose other than that for
which it is intended could result in adangerous situation.
5) Service
a) Repairs and service should only be performed by qualified tradesmen, and
only with original spareparts. Thisguarantees that thesafety of thepower tool is
maintained.

Specic safety precautions for polishing
• Polishing bonnets with drawstrings are not recommended, but if you are
usingone: Donot allow thepolishing bonnet or its drawstring to hang loose when
operating thepolisher. Tuckin or trim off any looseends. Looseand spinning
attachment strings can entangle your fingers or snag on theworkpiece.
• This angle polisher is only intended for dry polishing.
• Only use therecommended parts and/or accessories.
• Theangle polisher must not be used by persons under theage of 16years.
• Theangle polisher must not be used on materials containing asbestos.
a) This power tool is solely intended for thepurpose of polishing. Readall
safety warnings, instructions, illustrations, and specifications provided with
thistool. Failure to adhere to all of thefollowing instructions can result in electric
shock, fire and/or serious injury.
b) Operations such as grinding, sanding, wire brushing or cutting-off are not
recommended to be performed with this powertool. Theuse of this power
tool to perform tasks for which thetool was not intended, can lead to danger and
personal injury.
c) Never use accessories which are not designed for use with this type of tool
and which are not recommended by themanufacturer. Evenif theaccessory can
be attached to your power tool, there is no guarantee that it can be used safely.
d) Therated speed of theaccessory must at least correspond to themaximum
rated speed of thepowertool. Accessories which rotate faster than their rated
speed can break and shatter.
e) Theouter diameter and thickness of theaccessory must be within
themarked capacity of your electric handtool. Ifanaccessory is thewrong
size, it will not fit theguard and will not be able to be controlled properly.
f) Do not use adefective accessory. Inspect theaccessory and make sure there are
no splits or cracks in thegrinding wheels; cracks or wear and tear on thebacking
plates, loose or torn bristles on thesteel brush wheels. Ifyou drop your power
tool or accessory, check for damage. Iftheaccessory is damaged, use anew/
undamaged accessory. Afterinspecting thetool and attaching anaccessory, keep
yourself and others outside of thepower tool’s danger zone and let it run at full
speed for one minute. Damaged accessories will normally break during this test period.
g) Wear personal protective equipment. Depending on how you use
themachine; use avisor/face protection or safety glasses. Ifnecessary use
amask, ear protection, gloves, and apron/work clothing to protect you from
small shards of metal or splinters from thework object. Theeye protection
you use must be able to protect against flying debris produced in different working
positions. Thebreathing protection should be able to filter any particles produced by
thework. Prolonged exposure to high levels of noise can result in hearing damage.
h) Keep children at asafe distance from theworkarea. Everyone at
theworkplace must wear personal protective equipment. Debris from
theworkpiece or from adamaged accessory can fly off and injure people outside
of theimmediate workarea.

i) Position themains lead well away from therotating accessory. Ifyou lose
control, thelead can be sliced through or become entangled and pull your hand or
arm into therotating accessory.
j) Never put thepower tool down before theaccessory has completely
stopped rotating. Arotating accessory can fasten on thework surface causing
you to lose control of thetool.
k) Never leave thepower tool switched on while carrying it at yourside.
Accidental contact with therotating accessory could snag your clothing, pulling
theaccessory into yourbody.
l) Clean theventilation ports of themotor regularly. Thefan of themotor draws dust
into thehousing. Alarge build-up of metal dust particles can lead to electrical hazards.
m) Do not use thepower tool near flammable material. Sparks can easily ignite
flammable material.
n) Do not use accessories, which require liquid coolants. Theuse of water or
other liquid coolants can result in electrocution orshock.
Kickback and related warnings
• Kickback is asudden reaction to awedged or stuck wheel, backing plate, brush,
or some other accessory. Pinching or snagging causes rapid stalling of therotating
accessory which in turn results in thepower tool thrusting violently in theopposite
direction of theaccessory’s rotation at thepoint of binding.
• Kickbacks are theresult of thepower tool being used in anincorrect manner, on
incorrect objects, or under incorrect conditions and can be avoided by observing
thefollowing precautions.
a) Hold thepower tool firmly and position your arms and body so that you
can resist kickback forces. Always use theauxiliary handle if there is one,
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. Theaccessory can be
thrown back onto yourhand.
c) Do not stand in thearea, where thepower tool is likely to end up if
akickback were tooccur. Kickback will propel thetool in theopposite direction
to thewheel’s rotation at thepoint of snagging.
Outdooruse
• If thepolisher is used outdoors, it is recommended that it is plugged into asocket
protected by aresidual current device (RCD). TheRCD should be rated to trip at
acurrent of 30mA.
• Only use cables and connectors designed for outdooruse.

Before use
• Make sure that thepolishing wheel is securely fastened to thespindle.
• Make sure that thepolishing wheel can be turned byhand.
Operating instructions
Starting /Stopping
• Always hold thepolisher in both hands and start and stop thepolisher only when
thepolishing sponge is resting on thesurface to be polished.
• Always start polishing on thelowest speed by setting theregulator (4) to MIN
before pressing thetrigger (6). Pressin thetrigger lock button (5) if you want
thepolisher to keep running all thetime.
• Switch thepolisher off by pressing in thefront of thepower trigger (6) and then
releasingit.
Variable speed control
Set thedesired speed, from MIN to 6(max), using theregulator (4). Always begin
on thelowest speed (MIN) and increase during operation for thebest results. Ifyou
are unsure, it is agood idea to test thepolisher at different speeds on atest surface
before startingwork.
Changing polishing sponge/ bufng pad
Thevarious accessories which can be used with thepolisher are all referred to as
polishing spongebelow.
1. Unplug thepolisher and remove thepolishing
sponge (11) from thebacking pad (10).
2. Thepolishing sponge should be centred on
thebackingpad. Thisis easiest to achieve by
holding thepolishing sponge underneath and
pressing thebacking pad onto it fromabove.
Ifthepolishing sponge is fitted in this way, it is
easy to make sure that it is centred,i.e., that it
protrudes equally all theway round theedge of
thebackingpad.
Vibration level
Thepolisher normally vibrates during use due to its oscillating action.
If thepolisher vibrates agreat deal, check that thepolishing sponge is centred on
thebackingpad. Youcould also try adjusting thespeed until thepolisher vibratesless.
Thereis also away of balancing thebacking pad in relation to theweight of
thepolishing sponge (see thenext section).

Balancing the backing pad in case of abnormal vibrations
• Thebacking pad is factory-balanced for apolishing sponge of therecommended
dimensions.
• This factory-balancing is suitable for most polishing sponges with equivalent
dimensions and normally no adjustment is necessary.
• However, if abnormally heavy vibrations are experienced when using apolishing
sponge of another size, thebacking pad can be balanced by moving
acounterweight on thespindle.
• Thecounterbalance can only be used to compensate for weight differences up to
20g from therecommended polishing sponge weight.
Thecounterweight is adjusted using theincluded Allenkey.
1. Push thebacking pad inwards
(towards thepower trigger) so
that theadjusting screw (12) is
lined up with thehole (9).
2. Insert theincluded Allen key
(8) through thehole (9) and
into theadjusting screw (12).
Turning theadjusting screw,
moves asmall counterweight
(13) in/out to compensate
for thechange in weight of
thepolishing spongeused.
- Turn theAllen key clockwise
if thenew polishing
sponge is heavier than
thepreceding sponge.
- Turn theAllen key
anticlockwise if thenew
polishing sponge is lighter
than thepreceding sponge.
Thepicture shows how to balance
thebacking pad.
