1. Explanation of symbols used
This symbol indicates a potential danger to you or for the tool.
Under this symbol you can nd important information on how to
avoid injuries and damage to the power tool.
Danger of electrical shock
i
Indicates tips for use and other particularly useful information.
2. General Safety Instructions
CAUTION! Read all the instructions. Non-observance of the instructions below can cause
electric shock, re and/or serious personal injuries. The term "power tool" used
below covers both mains-operated power tools (with supply cord) and battery-
operated power tools (without supply cord).
1. Work area safety
a) Keep your workplace clean and well lit. Disorderly or unlit workplaces may result
in accidents.
b) Never use the tool in hazardous areas that contain ammable liquids, gases
or dusts. Power tools generate sparks that can ignite the dust or vapours.
c) Keep children and other persons away when using the power tool. You can
lose control of the tool if you are distracted.
2. Electrical safety
a) The tool plug must t into the socket-outlet. The plug may not be modied in
any form. Do not use adaptor plugs together with protective-earthed tools.
Unmodied plugs and suitable sockets reduce the risk of an electric shock.
b) Avoid physical contact with earthed surfaces such as pipes, heating
elements, stoves and refrigerators. The risk through electric shock increases if
your body is earthed.
c) Keep the equipment away from rain and moisture. The risk of an electric shock
increases if water penetrates electrical equipment.

EN
3
HV4500
d) Do not misuse the supply cord by carrying the tool by the cord, hanging it
from the cord or by pulling on the cord to remove the plug. Keep the supply
cord away from heat, oil, sharp edges or moving tool parts. Damaged or
twisted leads increase the risk of an electric shock.
e) If you work outdoors with a power tool, only use extension cables suitable
for outdoor use. The use of an extension lead that is suitable for outdoors reduces
the risk of an electric shock.
f) If you cannot avoid using the tool in a damp environment, use a suitable
ALCI/GFCI residual current operated circuit-breaker. Using a residual current
operated circuit-breaker avoids the risk of electric shock.
3. Personal safety
a) Be attentive. Pay attention to what you are doing and work sensibly with
a power tool. Do not use the tool if you are tired or under the inuence of
drugs, alcohol or medication. Just a moment of inattentiveness while using the
tool can lead to serious injuries.
b) Wear personal safety equipment and always wear safety goggles. Wearing
personal protective equipment, such as dust mask, non-slip safety shoes, safety
helmet or ear protection, depending on the type of power tools, reduces the risk of
injury.
c) Avoid accidental starting-up. Make sure that the electric tool is switched o
before you connect it to the power supply, pick it up or carry it. Accidents can
occur if you carry the power tool while your nger is on the switch or if you connect
the power tool to the power supply while switch is on.
d) Remove setting tools or wrenches before switching on the power tool. A tool
or wrench that is in a rotating tool part can lead to injuries.
e) Avoid an unnatural posture. Ensure that you are standing securely and have your
balance at all times. This ensures that you can control the tool better in unexpected situations.
f) Wear suitable clothing. Do not wear wide clothing or jewellery. Keep your
hair, clothes and gloves away from moving parts. Loose clothing, jewellery or
long hair can be caught in moving parts.
g) This power tool can be used by persons over the age of 14 as well as by
people with restricted physical, sensory or mental abilities or who have
little experience or knowledge about it, providing they are supervised or
instructed on how to use the power tool safely and what risks are involved.
Children shall not play with the power tool.

HV4500
4. Power tool use and care
a) Do not overload the tool. Use the power tool designed for the work that you
are doing. You work better and safer in the specied performance range if you use
the suitable power tool.
b) Do not use power tools whose switch is defective. A power tool that cannot be
switched on or o is dangerous and has to be repaired.
c) Remove the plug from the power source before carrying out tool settings,
changing accessories or putting the tool away. This precautionary measure
prevents unintentional starting of the tool.
d) Store unused power tools so that they are inaccessible to children. Do not
let persons use the tool who are not familiar with it or who have not read
these instructions. Power tools are dangerous when they are used by inexperienced
persons.
e) Take proper care of your tools. Check whether the moving parts function
trouble-free and do not jam, whether parts are broken or damaged so that
the tool function is impaired. Have damaged parts repaired before using
the tool. Many accidents have their origin in power tools that have been maintained
badly.
f) Use the power tool, accessories, insert tools, etc. in accordance with these
instructions and in a fashion specied for this special tool type. Take the
working conditions and the activity to be carried out into consideration. The
use of power tools for purposes other than the intended ones can lead to dangerous
situations.
5. Service
a) Have your tool repaired only by qualied specialist personnel and only with
original spare parts. This ensures that the tool safety 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
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.

5. Field of application
Many dierent coating substances can be processed with this tool.
6. Coating Materials Suitable for Use
Interior wall paint (dispersions and latex paint)
Water and solvent-based paints, nishes, primers, clear nishes, staining sealers and
wood sealer preservatives.
7. Coating Materials Not Suitable for Use
Materials that contain highly abrasive components, facade paint, caustic solutions and
acidic coating substances. Flammable materials.
8. Preparation of the workplace (for interior wall paint)
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 over spray.
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.

HV4500
9. Preparation of the Coating Material
•
Mix the material well in the original container. When using interior wall paint, an
agitator is recommended.
i
The viscosity (thickness) of your paint may need thinning before spraying. Start
with a 10% dilution. Stir well. If further thinning is required dilute by 5% and
continue stirring until the nish of chosen coating is satisfactory.
Some units are supplied with a cup to measure the viscosity of coating material.
Fill the cup with coating material and allow to pour through. The ow of the
coating will change from continuous to broken. Time how long this
takes and use the table below as a guide to reach satisfactory viscosity.
Model Number of seconds
HV1900 50 seconds
HV2901 120 seconds
HV3900 130 seconds
HV3901 130 seconds
HV4500 120 seconds
HV5500 130 seconds
HV5901 150 seconds
To thin paint, add water to water-based paints and white spirit to oil-based
paints.
iSpray material that is at least at room temperature provides a better spray
result.
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.
Put the machine down only on a level, clean surface, otherwise it may suck in dust, etc.

Fig. 5 C = circular jet for corners, edges and hard-to-reach surfaces
12. Adjusting the Material Volume
Set the material volume by turning the material volume adjuster on the rear of the spray
gun (Fig. 6).
+ turn anticlockwise higher material volume
– turn clockwise lower material volume
13. Spray Technique
i
The spray result depends heavily on the smoothness and cleanliness of the
surface to be sprayed. Therefore the surface should be carefully prepared and
kept free of dust.
•
Cover all surfaces not to be sprayed.
•
Cover screw threads or similar parts of the target object.
iImportant: 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 5 - 15 cm, depending on the desired spray jet
width. When you are using interior wall paint, the distance should be about 20-30 cm.

US
9
HV4500
Fig. 7 A / 7 B: CORRECT Even distance to the object.
Fig. 7 C: INCORRECT An uneven distance will result in uneven paint
application.
•
Move the spray gun evenly side to side or up-and-down, depending on the spray
pattern setting.
•
An even movement of the spray gun results in an even surface quality.
•
When coating material builds up on the nozzle and air cap, clean both parts with a
solvent or water.
i"Cross spray" when using paint with a poor covering capacity or if the
surface is highly absorbent (Fig. 8).
iInterior wall paint in strong colour shades should be applied at least twice.
This will ensure good coverage.
