1. Machine description
1.1 Application:
Utilization:
This machine is designed exclusively for washing by means of pressurized water jet, objects, things or
surfaces eligible to be treated by the mechanical action of pressurized water jet and by the possible
chemical action of liquid detergent additives. The liquid detergent additives must be chosen in
accordance with the chemical compatibility of the surfaces to be washed.
High-pressure cleaners can clean with either cold or hot water, but for technical reasons the pumps in
the high-pressure cleaners must not run with water temperatures above 60 °C. Higher temperatures
require equipment which heats up the water on the outlet side of the high-pressure cleaner. In most
cases the water temperature will improve the cleaning process, in particular on greasy surfaces.
The high-pressure cleaner requires either 3 x 230 volt or 3 x 400 volt. Please see the nameplate.
The high-pressure cleaner must only be used with process water or collected rainwater with a purity
equal to tap water. The inlet side requires a 3/4 inch. pipe diameter with a flow of at least 10 L / min.
The high-pressure cleaner is relatively noiseless with a noise level below 70 dB. Make sure the
operator wears hearing protection if the work is considered damaging to hearing. This means
that noise exposure even below 85 dB(A) may require the use of hearing protection (4).
Examples of possible use:
Farming: Intensive keeping- and breeding firms, farms, slaughterhouses.
Workshops: Maintenance of tractors and agricultural machinery.
.
Congratulations with your choice of a Kent high-pressure cleaner. You have purchased a unit
with high technological value. It is a professional and reliable machine which you can use for
many years. Thus, we ask you to read and follow the instruction manual carefully.
This instruction manual is an integral part of
the machine and must be read carefully
before the unit is installed, turned on and

2. User guide
2.1 Preparation
Make sure that personal protective equipment is
within reach. We recommend that operators
wear protective clothing, protective goggles,
gloves and safety footwear during operation of
the high-pressure cleaner.
This unit has been tested and test-run in the factory, but after transportation it may require a fine
adjustment and visual check of all operations. Always check for loose wires, screws and defect joints.
Pay particularly attention to thread connections and the equipment fittings at the outlet and inlet
connections on the high-pressure cleaner.
The work must always be planned in compliance with good ergonomic principles, and breaks must be
organized during large and continuous tasks. Avoid straining of back and arms and plan the workday
after consulting management and avoid stress. Vary your work or take appropriate breaks in order to
avoid monotonous strain.
Check oil level through pump indicator glass. Change oil after 25 hours of operation. Then after each 200
hours of operation. Use a good motor oil, SAE 20/30.
Check that the machine is plugged into correct mains voltage.

2.2 Start up
This machine must only be operated by persons over 18 years.
(Danish At-instruction (At = Danish Working Environment Authority) D. 2.20 November 2006):
Young persons covered by compulsory education must not operate pressure equipment.
Young persons over 15 years not covered by compulsory education must, as a main rule, not operate pressure
equipment with a pressure over 7 MPa (70 bar).
However, young persons over 16 years not covered by compulsory education and working within agriculture and
horticulture are allowed to work with pressure equipment over 7 MPa (70 bar). The pressure equipment must only
be used for cleaning, painting, rust inhibiting or the like.
Young persons under 18 years must only be engaged with work 4 hours daily if wearing self-contained respiratory
protective equipment.
For prolonged use of high-pressure equipment use vibration dampening gloves like type TEGERA 9185
Before start:
Remove items or goods that may be damaged during high-pressure cleaning.
Use wheel chocks if the high-pressure cleaner is placed on a sloping surface.
The high-pressure cleaner must only be used on a ladder if it is a platform ladder with barriers. The
height to the platform must not be more than 3 m. The platform ladder must be designed in compliance
with the principles of EN 131 or with a similar safety level.
Connection of the high pressure hose and lance:
1. Connect one end of the high-pressure hose to the gun, the other end has to be connected to the
outlet of the pump. After that mount the lance to the gun.
2. Before use of the machine, inspect high pressure hose to make sure it is not damaged. In case of
replacement make sure that the new hose has at least the same specifications as the original one.
Technical specifications (max. working pressure, date of manufacturing, name of manufacturer) must
be marked on the outer sleeve of the hose.
Connection to the water supply
1. The maximum temperature of the inlet water must not exceed 60° C (140° F).
2. Connect the water supply to the INLET port by means of a reinforced hose (min. 15 bar/200
psi) with the internal diameter of not less than 19 mm (3/4”)
3. Considering that the water flow decreases in accordance with the length of the hose,
make sure that the quantity of the water reaching the machine is at least 10 l/min.
Important:
Make sure that the machine is fed with clean water during use. Running the machine without water, or
with dirty, sandy water, or containing corrosive chemicals, causes serious damage to the machine itself.
Connection to the electrical supply:
1. Make sure that the mains voltage is the same as shown on the identification Label on the machine.
2. Make sure that the plug complies with your local regulations, and that it is proved with ground
connection.
3. The power outlet must be protected by a differential magnetic interrupter having a sensitivity of less
than 30, mA.
4. Do not connect any other appliances to the same outlet.
5. Insert the plug after making sure that the switch on the machine is in the OFF position.

Chemicals dosage:
Fill plastic can with desired chemical. Mount injector suction hose in can. Open double nozzle pipe
valve, and approx. 10 % chemical will be added to water.
Indoor high-pressure cleaning is only permitted in halls and together with good ventilation. If you feel
unwell during cleaning, stop working immediately and go outside. The reason may be the cleaning
detergent which you may have used during cleaning. Thus, check carefully if these materials are being
used in a safe and environmentally correct way. Information can often be found on the containers of the
detergent. Never experiment with additives which can influence the health of the persons present and
domestic animals, if any. In case of contact with eyes, rinse immediately with plenty of water and seek
medical advice. Show the label of the cleaning detergent where possible, e.g. bring the container in
order to obtain the best medical treatment.
The quality of cleaning detergents may vary, and you must make sure they are suitable for high opera-
ting temperatures under high pressure. Consider the environment in particular where there is run-off to
unprotected drainage. Obtain data sheets, if necessary, with definition of class of danger of the substan-
ce and personal protection on a scale of 1 to 6 where 6 is the most hazardous! Never use aggressive
substances such as acids, solvents or explosive substances together with this unit. Use a less corrosive
cleaning detergent, if possible.
Start-up of machine:
1. Now you can turn on the water.
2. Hold the gun in open position for venting.
3. Switch the machine on.
4. The pressure can be adjusted on the double nozzle pipe.
Respiratory protection equipment / hearing protection (Danish At-instruction (At = Danish Working
Environment Authority) D. 2.20 November 2006): Employees must wear suitable respiratory protection
equipment during work under 2.5 MPa (25 bar) if aggravating factors such as chemicals harmful to health by
inhalation, micro-organisms or organic origin residue are present.
Always wear suitable respiratory protection equipment during work over 2.5 MPa (25 bar).
The respiratory protection equipment must contain at least a P2 filter protecting against both solid particles and
liquid aerosols. The safest method is to use self-contained respiratory protection equipment. There can often be
doubt about the nature and concentration of the air pollution as it is difficult to determine what will detach from the
sprayed surfaces. If work is carried out for more than three hours on a daily basis the respiratory protection
equipment must be self-contained or filtering by turbo-unit (blower).
Inhalation of aerosols with surfactants (e.g. soap) and fat and protein residue constitutes a risk of developing
respiratory disease and is also mucous membrane irritant (3).

Inspection of water filter
It is important to inspect the water filter prior to machine start-up. Please keep in mind that a clean
water filter means longer service life and operation of the machine.
Important:
Use only biodegradable detergents with pH value between 7 and 12. These detergents must comply
with the laws and regulations applicable in the country in which they are used. The utilization of this
machine must be strictly respected. Any other use must be considered as incorrect. The manufacturer
cannot be held responsible for damage caused by incorrect use of the machine. The machine must
not be tampered with for any reason. In case of tampering the manufacturer declines any responsibili-
ty on the functioning and safety of the machine.
During work planning it must be taken into account that aerosols, especially small aerosols, stay in the
air for a long time, even after the pressure work has stopped. Thus, it will often be necessary to wear
personal protection equipment, even after the actual pressure work has stopped. Very small aerosols
may stay in the air for up to 1.5 hours.
Class P2
has a better elimination degree and therefore better protection. It can be used against harmful and toxic
dust, but not against radioactive dust, bacteria and virus. These filters can protect solely against solids and
against both solids and liquid aerosols. If the filter is tested according to EN149:2001 the filter protects
against both solids and liquid aerosols. For further information, please see At-instruction (At = Danish Working Environment
Authority) D.5.4 January 2008.
Filter respiratory protection
equipment.
Particulate filters are divided into
three classes:
•P1 low-efficiency filter
•P2 medium-efficiency filter
•P3 high-efficiency filter
Self-contained respiratory
protection equipment
At-instruction (At = Danish Working Environment Authority) D.5.4 January 2008:
The employer must make sure that the employees wear hearing protection as soon as they start work which is
considered to be damaging to hearing. This means that noise exposure even below 85 dB(A) may require the
use of hearing protection.
Respiratory protection equipment and hearing protection must fit together and should preferably be tested
together.
Filter face mask.

General precautions for use:
1. Keep the machine out of the reach of children.
2. High-pressure water jets must not be directed against persons or animals, electrical equipment of
the machine itself. Do not use the machine when persons and/or animals are within the reach of
the jet.
3. The user must operate the machine in safe conditions and situations avoiding any situations of
potential danger to himself or other persons, in particular, the user will have to:
-Avoid operating in unstable balance conditions.
-Remember that the high pressure generates a recoil when the gun is operated. The force of this
recoil is less than 20 N (approx. 2 kg).
-Use adequate protection clothing.
-Wear protection goggles and anti-slip rubber shoes.
- Avoid contaminating the environment with pollution, toxic or harmful substances.
4. This machine is built in compliance with the requirements of the current safety regulations. In any
case the use of electrical appliances involves the respect of some basic rules, namely:
- Do not touch electrical parts or components.
-All inspection, maintenance or repair operations must be made by qualified personal only. In
any case always disconnect the plug from mains before proceeding on any of the above
mentioned operations.
-In case you need to use an extension cord, check that the connection is water tight. Keep all
connections off the ground to avoid possible contacts with water.
5. Do not pull power cord to unplug.
6. While the machine is running, do not cover it and do not place it in a closed space with insufficient
ventilation.
7. Do not leave the machine running for more than 5 minutes with the gun closed. Should it run for a
longer period, the temperature of the recirculating water will increase rapidly and could risk
damaging the pump seals.
8. When the machine is not in use, lock gun trigger in safe position to prevent it form being opened by
accident.
9. For sake of safety use only original spare parts and accessories
- Should you need to remove or change the nozzle, turn off the machine and bleed pressure from
the hose.
The manufacturer declines any responsibility for damages caused by non-
compliance with the destination of use, with the instructions and warnings contained
in this instruction manual.
Precautions for storage/frost:
We recommend filling the pump with anti-freeze equal to anti-freeze for cars if the machine will be stored
in a place with a risk of being exposed to frost, or will not be used for more than 3 months. In case of low
temperatures some parts may freeze or settle if the machine has been stored for a long time. Thus, we
recommend that you turn the shaft by the key supplied with the machine prior to start-up. This procedure
allows you to check if the machine is frozen or blocked by other reasons. By taking these precautions
prior to start-up you can avoid destroying the machine. Please remember to remove the key from the
shaft prior to start-up.
