Safety Notes
General Power Tool Safety Warnings
Read all safety warnings, instructions
including Material Safety Data Sheets
(MSDS), and container labels provided with the paints
and solvents. Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious injury.
Save all warningsand 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.
Workplace safety
fKeep work area clean and well lit. Cluttered and dark ar-
eas invite accidents.
fKeep children and bystanders away while operating a
power tool. Distractions can cause you to loose control.
Electrical safety
fPower 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.
fAvoidbodycontactwithearthedorgroundedsurfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
fDo not expose power tools to rain or wet conditions.
Waterenteringapowertoolwillincreasetheriskofelectric
shock.
fDo 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.
fWhen operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suitable
for outdoor use reduces the risk of electric shock.
fIf operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected
supply. Use of anRCD reduces the risk of electric shock.
Personal safety
fStay 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 underthe influence of drugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
fUse safety equipment. Always wear eye protection.
Safety equipment such as dusk mask, non-skid safety
shoes, hard hat, or hearing protection used for appropri-
ate conditions will reduce personal injuries.
fPrevent 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 en-
ergising power tools that have the switch on invites acci-
dents.
fDo not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
fDress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
Use and care of the power tool
fDo 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 designed.
fDo 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.
fDisconnect 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.
fStore 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.
fMaintain power tools. Check for misalignment or bind-
ing 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.
fUse the power tool, accessories and application tools
etc. in accordance with these instructions, taking into
account the working conditions and the work to be per-

formed. Use of power tools for operations different from
those intended could result in a hazardous situation.
Service
fHave yourpowertoolserviced 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 Fine-spray Systems
fKeep area clean well lit and free of paint or solvent con-
tainers, rags, and other flammable materials. Sponta-
neous combustion may occur. Fire extinguisher equip-
ment shall be present and working at all times.
fProvide for good ventilation in the spraying area and
for sufficient fresh air in the complete room. Evaporat-
ing inflammable solvents create an explosive environment.
fDo not use materials with a flashpoint below 21 °C for
spraying and cleaning. Use water-based materials,
non-volatile hydrocarbons or similar materials. Fast
evaporating solvents create an explosive environment.
fDonotsprayinthevicinintyofignitionsources,suchas
static electricity sparks, open flames, pilot lights, hot
objects, engines/motors, cigarettes and sparks from
plugging in or unplugging power cords or operating
switches. Such spark sources can ignite the spraying vi-
cinity/environment.
fDo not spray any liquid of unknown hazard potential.
Unknown materials can create hazardous conditions.
fWear additional protective equipment such as appro-
priate protective glovesand protective masks or respi-
rators when spraying or handling chemicals. Wearing
protective equipment for the appropriate conditions re-
duces the exposure to hazardous substances.
fNever point the spray jet against yourself, towards oth-
er persons or animals. Keep your hands and other body
parts away from the spray jet. If the spray jet should
penetrate the skin, seek medical attention immediate-
ly from a doctor. The material being sprayed can even
penetrate the skin through a glove and be injected into
your body.
fDonottreat aninjectionasa simplecut.Ahigh-pressure
spray is able to inject toxins into the body andcause seri-
ousbodilyinjury.Intheeventthataninjectionoccurs,seek
medical attention immediately.
fBe aware of possible hazards from the spray material.
Observe the information on drums/tanks/tins as well
as manufacturer information of the spray material, in-
cluding the request to wear personal protective equip-
ment. The manufacturer's instructions are to be observed
in order to reduce the risk of fire as well as injuries caused
through toxins, carcinogens, etc.
fUse only nozzles/nozzle inserts specified by the manu-
facturer. Never spray without the nozzle protection
mounted. Use of a special nozzle insert with the corre-
sponding nozzle protection reduces the probability that a
high-pressure jet penetrates the skin and injects toxins in-
to the body.
fExercisecautionwhencleaningandchanging nozzle in-
serts. If the nozzle insert should become clogged dur-
ing spraying, follow the manufacturer's instructions
for switching off the system and relieving the pressure
before removing the nozzle. Fluids under high pressure
can penetrate the skin, inject toxins into the body and lead
to serious injury.
fKeep the plug of the mains cord and the trigger switch
of the spray gun clear of paint and other fluids. Never
hold the cord by its connectors to support it. Failure to
follow the instruction can lead to electric shock.
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 author-
ised 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 sock-
et elsewhere.
Productssold in AUSand NZonly: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.

Technical Data
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted sound pressure level of the product
is 74 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).
Wear hearing protection!
Vibration total values ah(triax vector sum) and uncertainty K
determined according to EN 60745:
ah<2.5m/s2, K= 1.5 m/s2.
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 expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications,withdifferentaccessoriesorpoorlymaintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of thelevel 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 sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
fromthe effectsofvibration suchas:maintain thetooland the
accessories, keep hands warm, organise work patterns.

The spray mist contaminates the environment. When spray-
ing in enclosures, surfaces not covered can become contami-
nated.
The spray surface must be clean, dry and grease-free.
– Roughen smooth surfaces and then remove the sanding
dust.
Suitable spray materials and recommended diluting
agents
fWhen diluting, pay attention that the spray material
and the diluting agent correspond. When using a faulty
diluting agent, lumps can develop that can lead to clogging
of the spray gun.
The tool is not suitable for processing dispersion paint (wall
paint/latex).
Please also observe the practical advice/tips of the spray ma-
terial manufacturers.
Diluting Spray Material
For spray material that needs to be diluted, proceed as fol-
lows:
– Take the measuring cup 22.
– Stir the spray material thoroughly.
– Fill a sufficient quantity of spray material into the spray-
material container 11. (see “Filling in Spray Material”,
page 17)
– Dilute the spray material by 10 % with paint thinner. Ex-
amples:
– Stir the spray material thoroughly.
– Carry out a test-spray run on a test surface. (see “Spray-
ing”, page 17)
When the spraying pattern is perfect, start the spray job.
or
When the spraying result is not satisfactory or when no paint
comesout, pleasecontinue asdescribedunder“Correctionof
Malfunctions” on page 19.
Filling in Spray Material (see figures B1–B2)
fBefore any work on the machine itself, pull the mains
plug.
– Unscrew the container 11 from the spray gun.
– Turn the suction tube 10 so that the spray material can be
sprayed with almost no residue:
– Fillthespray material into thecontainerandscrewthecon-
tainer firmly to the spray gun.
Starting Operation
fObserve correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
fPay attention that the power tool cannot draw in dust
or other contamination during operation.
Switching On
– Plug the mains plug into a socket outlet.
– Grasp the power tool and point it at the spray surface.
The power tool is equipped with a two-step trigger switch 16.
The first step starts the turbine. The second step transports
the spraying material.
– Pull the trigger switch 16 until spraying material starts to
come out.
Switching Off
– Release the trigger switch 16.
– Pull the mains plug from the socket outlet.
Working Advice
Spraying (see figures C–D)
Note: Observe the wind direction when operating the power
tool outdoors.
– Firstly, carry out a test-spray run and adjust the spray pat-
tern and the spray material quantityaccording to thespray
material. (For adjustments, see the following sections)
– Makesureto hold thespraygun vertical tothespray object
at a uniform clearance between 5 – 15 cm.
– Begin the spraying procedure outside the target area.
– Move the spray gun evenly cross-wise or up-and-down, de-
pending on the spray pattern setting.
Anevensurface qualityisachieved when the pathsoverlap
by4–5cm.
– Avoid interruptions within the spray surface.
Guiding the spray gun evenly will provide uniform surface
quality.
Non-uniform clearance and spray angle lead to heavy forma-
tion of paint mist and thus to an uneven surface.
– End the spraying procedure outside the target area.
Never spray the container completely empty. When the suc-
tion tube no longer immerses in the spray material, the spray
jet will break off, resulting in a non-uniform surface.
When coating material builds up on the nozzle and air cap,
clean both parts with the corresponding solvent.
Note:Only place down the power tool on a level and clean sur-
face so that it can not tip over.
