1. Explanation of symbols used
This symbol indicates a potential danger for you or for the device.
Under this symbol you can nd important information on how to
avoid injuries and damage to the device.
Danger of electrical shock
i
Indicates tips for use and other particularly useful information.
Devices and accessories marked with this symbol are suitable for
processing high-viscosity materials such as e.g. interior wall paints
(dispersions and latex paints).
If a material bears this logo, it is particularly well suited for use with
the relevant device.
2. General Safety Instructions
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refer 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 ammable 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.
Unmodied 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.

3
HV2501EU EN
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 or
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 shock.
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
inuence 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 injuries.
c) Prevent unintentional starting. Ensure the switch is in the o-position before
connecting to power source and/or battery pack, picking up or carrying the
tool. Carrying power tools with your nger on the switch or energising power tools
that have the switch on invites accidents.
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.
4. Power tool use and care
a) Do not force the power tool. Use 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.

EN
4
HV2501EU
b) Do not use the power tool if the switch does not turn it on and o. 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 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 aect the power tool's
operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) 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 dierent from those intended could
result in a hazardous situation.
5. Service
a) Have your power tool serviced by a qualied repair person using only
identical replacement parts. This will ensure that the safety of the power tool is
maintained.
b) If the supply cord is damaged, it must be replaced by the manufacturer or its
service agent or a similarly qualied person in order to avoid a safety hazard.
3. Safety Instructions for Spray Guns
•
Caution! Wear breathing equipment: Paint mist and solvent vapours are damaging
to health. Always wear breathing equipment and only work in well ventilated rooms
or rooms using supplementary ventilating equipment. It is advisable to wear working
clothing, safety glasses, ear protection and gloves.
CAUTION: DANGER OF INJURY!
Never point the spray stream towards human beings or animals.
Socket-outlets and plugs must be masked. Risk of an electric shock as a
consequence of sprayed material entering the socket-outlet!

5
HV2501EU EN
Attention! Never operate the device if the nozzle seal is either
damaged or missing. If the nozzle seal is either missing or damaged
liquids can enter the device and increase the risk of an electric shock.
Check the nozzle seal before each use.
•
Do not use the spray guns to spray ammable substances.
•
The spray guns are not to be cleaned with ammable solvents.
•
Caution against dangers that can arise from the sprayed substance and observe the
text and information on the containers or the specications given by the substance
manufacturer.
•
Do not spray any liquid of unknown hazard potential.
•
The device may not be used in workplaces covered by the explosion-protection
regulations.
•
To avoid the hazard of explosion when spraying, provide for eective natural or
articial ventilation.
•
There must be no sources of ignition such as, for example, open res, smoke of lit
cigarettes, cigars and tobacco pipes, sparks, glowing wires, hot surfaces, etc. in the
vicinity during spraying.
•
When working with the HV2501EU indoors as well as outdoors ensure that no solvent
vapours are sucked in by the spray gun.
•
The spray gun is not a toy; children must therefore not be allowed to handle it or play
with it.
•
Before working on the spray gun remove the power plug from the socket-outlet.
•
Cover areas that are not to be sprayed. When working keep in mind that wind, for
example, may transport paint mist over great distances and cause damage.
•
Never open the device yourself in order to carry out repairs in the electrical system!
•
The units may only be used with a functional valve. If paints rises in the ventilating
hose (Fig. 1, 13) do not operate the unit further! Dismantle and clean the
ventilating hose, valve and diaphragm and replace the diaphragm if necessary.
•
Do not lay the spray gun down.
With original Earlex accessories and spare parts, you have the guarantee that all
safety regulations are fullled.

5. Field of application
HV2501EU has been specially developed for the application of interior wall paints.
6. Coating Materials Suitable for Use
Interior wall paint (dispersions and latex paint)
7. Coating Materials Not Suitable for Use
Water and solvent-based paints, nishes, primers, 2-component paints, clear nishes,
automotive nishes, staining sealers and wood sealer-preservatives.
Materials that contain highly abrasive components, facade paint, caustic solutions and
acidic coating substances. Flammable materials.
8. Preparation of the workplace
Socket-outlets and plugs must be masked. Risk of an electric shock as a
consequence of sprayed material entering the socket-outlet!
Mask all the areas and objects that are not to be spray painted, or
remove them from the work area. No liability is assumed for damage
due to overspray.
Silicate paint corrodes glass and ceramic surfaces upon contact! All
such surfaces must therefore be completely covered.
iPay attention to the quality of the adhesive tape used.
Do not use excessively strong adhesive tape on wallpaper and painted
surfaces, in order to avoid damaging these surfaces when removing the
tape. Remove adhesive tape slowly and evenly; do not use jerky movements.
Do not leave adhesive tape on surfaces any longer than necessary, in order
to minimise the possibility of residues when removing.
Also observe the adhesive tape manufacturer's instructions.

7
HV2501EU EN
9. Preparation of the Coating Material
iSpray material that is at least at room temperature (e.g. diluted with warm
water) provides a better spray result.
Attention! Do not heat spray material above 40°C.
Interior wall paints can be sprayed undiluted or slightly diluted with the spray attachment
provided. Detailed information is available in the technical data sheet of the manufacturer
(Internet Download).
1.
Stir the material thoroughly and dilute it in the container as per the recommended
dilution (an agitator is recommended for stirring).
Thinning recommendation
Sprayed material
Interior wall paint (dispersions and latex paint) Dilute by 0-10 %
2. If the feed rate is too low even at maximum flow setting, dilute in steps of 5 - 10 % until
the feed rate meets your requirements.
10. Start-up
Before connecting to the mains supply, be sure that the supply voltage is identical with
the value given on the rating plate.
•
Unscrew the container from the spray gun.
•
Aligning suction tube. (Fig. 2)
If the suction tube is positioned correctly, the container contents can be sprayed without
almost any residue.
When working on lying objects: Turn the suction tube forwards. (Fig. 2 A)
Spraying work when working on overhead objects: Turn the suction tube rearwards.
(Fig. 2 B)
•
Place the container on a paper base and pour in the prepared coating substance with the
aid of the feed hopper included in the scope of delivery (Fig. 1, 14). Screw the container
tightly onto the spray gun.
•
Connect the front part with the rear part of the gun (Fig. 3).
•
Put the sprayer down only on a level, clean surface. Otherwise the machine could tip over!
•
Pull the trigger. The HV2501EU has a two-stage trigger. In the rst stage the turbine is
started. If the trigger guard is pressed further, the material is transported.
•
Adjust the spray setting on the spray gun.

HV2501EU
11. Selecting the Spray Setting (Fig. 4)
WARNING! Danger of injury! Never pull the trigger guard while adjusting
the air cap.
2 dierent spray jet shapes can be set by turning the adjustment ring (g. 4, 1)
Fig. 5 A = vertical at jet for horizontal surfaces
Fig. 5 B = horizontal at jet for vertical surfaces
12. Adjusting the Material Volume (Fig. 6)
Set the material volume by turning the regulator on the trigger guard of the spray gun.
- turn to the left  lower material volume
+ turn to the right higher material volume
13. Spray Technique
•
Cover all surfaces not to be sprayed.
iThe enclosed practice poster is ideal for familiarising yourself with
operation of the spray gun. After these initial spray attempts it is a
good idea to perform a spray test on cardboard or a similar surface,
in order to determine the material quantity required to achieve an
optimal spray pattern.
Important: Start at the edge of the area to be sprayed. Start the spray
movement rst of all, and then press the trigger. Avoid interruptions
within the area to be sprayed.
•
The spray movement should come from the arm, not just from the wrist. This ensures
that a uniform distance is maintained between the spray gun and the spray surface
during the spray operation. Select a distance of 20-30 cm, depending on the desired
spray jet width.
Fig. 7 A: CORRECT Even distance to the object.
Fig. 7 B: INCORRECT An uneven distance will result in uneven paint application.
•
Move the spray gun evenly cross-wise or up-and-down, depending on the spray
pattern setting.
•
An even movement of the spray gun results in an even surface quality.
•
If nozzle and air cap are soiled, clean both parts with water and solvent.
i
"Cross spray" when using paint with a poor covering capacity or if the
surface is highly absorbent (Fig. 8).
i
Interior wall paint in strong colour shades should be applied at least twice
(allow rst paint coat to dry rst). This will ensure good coverage.

9
HV2501EU EN
iImportant: Wipe o the nozzle and air cap regularly to
make sure they do not get blocked.
14. Interruption of Work
•
Turn the machine o.
•
During longer breaks, vent the container by briey opening and then closing it again.
•
Clean nozzle openings after an interruption in operation.
15. Taking Out of Operation and Cleaning

Information about the oscillation level
The specied oscillation level has been measured according to a standard test
procedure and can be used to compare against electric tools.
The oscillation level is also for determining an initial assessment of the vibrational
strain.
Attention! The vibration emission value can dier from the specied value when the
electric tool is actually in use, depending on how the electric tool is being used. It is
necessary to specify safety measures to protect the operating personnel.These measures
are based on an estimated shutdown during the actual conditions of use (all parts of the
operating cycle are taken into consideration here, for example periods when the electric
tool is switched o, and, when it is switched on but running without any load).
20. Environmental protection
The device and all accessories and packaging have to be recycled in an
environmentally friendly manner. Do not dispose of the appliance with
household waste. Support environmental protection by taking the appliance
to a local collection point or obtain information from a specialist retailer.
