Hazard levels
DANGER - Indication of an immediate danger potentially resulting in serious injuries or death.
CAUTION - Indication of a potential hazardous situation that may result in light injuries.
WARNING - Indication of a potential hazardous situation that may result in material damage.
Safety features
CAUTION - Safety features are designed to protect their users from injuries and these may not be altered
in any way or even put out of order . Any damaged items must be replaced with original spare parts only.
Protective guards on hot or rotating parts
The protective guards are designed for protection of operators using the high-pressure washer to avoid injuries
caused by temperatures of certain components of the combustion engine or injuries caused by rotating parts of
the device.
Safety features on the combustion engine and pump
The engine oil level safety switch (if fitted) serves for automatic deactivation of the engine in case the engine oil
level drops below the minimum threshold. That will prevent damage to the engine due to insufficient lubrication
of internal parts. However, this safety features does not substitute the need to check the engine oil level prior to
use of the device.
For further important information see the section – ENGINE (p. 3).
Scope of delivery
For depiction of delivery contents see the packaging or the purchase order. Check the contents completeness
when unpacking. Any items missing or any damages incurred in transport should be notified to the seller.
Additional items required
Source of clean water to fill water tank.
Assembly
The device itself is assembled in the manufacturing plant. Before connecting the hoses, remove the covers
from the high-pressure water outlet and inlet on the pump. The first operation requires connection of the high-
pressure hose, included in the delivery, with the control gun and nozzle to the high-pressure section of the
pump.
The next step requires filling of the supplied oil into the engine, as directed by instructions in the section
ENGINE (p. 3) and filling the tank with fresh petrol with octane rating of 95.
Commissioning
Water supply
CAUTION Avoid operating the pump without a water in water tank. Minimum 20L of water is required for
engine start. If the purity of supplied water cannot be guaranteed, the system needs a water filter placed before
the pump inlet to avoid influx of solid contaminants inside the pump.
If the pump has not developed pressure within 30 seconds following its
commissioning, switch the engine off and proceed in compliance with instructions

3
defined in the Troubleshooting section! Any dry cycling of the pump for a period
exceeding 30 seconds may result in damage!
Any material damage caused due to inobservance of this instruction renders the warranty void.
Engine
The engine MUST be filled with the correct amount of engine oil supplied with the
delivery before its first commissioning. The bottle with engine oil may contain larger
amount than required for the particular engine type. For specifics refer to the
Technical data section. For easier cold engine start, we recommend reducing the
water outlet pressure according to the instructions on page 8. Set the pump on a
horizontal surface. Open the oil sump plug, also fitted with the oil gauge. Fill the
engine with approximately ¾ of the oil amount required. Screw the plug back into the
oil sump. With the C switch se to the OFF (0) position (see the figure below), cycle
the engine by pulling the starter cord. Remove the plug, wipe the gauge dry and check
the engine oil level.
CAUTION: To get the correct reading, the gauge must be fully screwed in place. Top
up the oil to achieve the final level between the MIN and MAX marks.
Remove the plug and fill the tank with petrol carefully. To ensure full performance of the engine, use fresh petrol
with the octane rating of 91 or higher. The physical properties of old and vapid petrol are different and it may
cause an uneven run of the engine or reduced pump performance. Use clean and oil-free petrol only - your
engine is a four-stroke type.
DANGER
When in operation, the engine
produces carbon monoxide,
which is a colourless and odourless poisonous gas. Inhalation of carbon monoxide may cause nausea,
headaches, dizziness, vomiting or even death! The device may be used outdoors only, with proper
ventilation ensured. It is also necessary to prevent ingress of exhaust gases into enclosed rooms via
unsealed openings. When working with the engine on, turn the device in such direction, where the
exhaust does not remain pointed at persons standing in the vicinity or any opening in nearby structures
(garages, galleries, cellars, etc.). When in operation, the engine produces waste heat, resulting in heat-
up of various engine components (exhaust, engine cylinder), which may cause serious burns. These
components may cause fire, when in contact with flammable materials.
DANGER
Petrol fumes are extremely flammable and explosive substances that max cause burns, fire or even
explosion, when handled improperly. Let the engine cool down for 5 minutes before adding petrol into
the tank. Then proceed with careful removal of the tank lid and start pouring the petrol in with caution.
NEVER fill the fuel up to the rim, since petrol warms up during engine operation and swells, which may
result in leakage through the lid and subsequent explosion of fire. NEVER tip the high-pressure device
into such position, where petrol may leak from the tank. NEVER attempt to start the engine with damaged
components in the fuel supply, ignition or safety features.
The turn the fuel switch D into the ON (I) position.
Shift the speed control lever B into the position.
Shift the choke control lever A into the CHOKE
position.
Grasp the pump grip with one hand firmly and use the other
hand to hold the starter cord grip.
Pull the starter cord to the point, where you feel resistance
from the engine. Then pull the grip sharply to prevent recoil.
If the engine fails to start on the first attempt, depress the
gun and relieve the water pressure in a safe direction. Then
repeat the starting process by pull the starter grip again.

4
CAUTION! The starter cord recoil (engine
resistance against the direction of starter cord pull)
will draw your shoulder and hand towards the engine
faster than you are able to release is, this may result
in spraining, contusion or breakage of your limb.
Once the engine has started up, shift the choke control lever
A into the RUN position SLOWLY.
ENGINE SHUTDOWN
Engine shutdown comprises the following steps
Shift the engine speed control lever (page 4) B to ½ of the turn towards the position and let the engine
run for at reduced speed for 15-20 seconds. Then proceed with turning the engine ignition push switch C and
the fuel switch D into the OFF (0) position .
CAUTION The motor is equipped with a sensor that shuts down the motor if the motor oil
level oil level drops to dangerous levels. Disregard to the regular inspections may result in
irreversible damage to internal components of the engine. Such damage is not covered by
the warranty.
NEVER spray any water on the engine when hot. Such actions may cause ingress of water
into the fuel system or the ignition system. Clean the engine with a damp cloth and
compressed air to remove dust from the air filter compartment.

check
There may be rare cases, when the protective metal guards come loose during operation. These parts need to
be tightened, since long-term exposure of a loose guard to vibrations causes damage to the mounting holes. If
damaged, the protective guard on the exhaust, the air filter or the cooling fan must be replaced with original
spare parts, since that is the only way to ensure maximum operation safety.
Spare parts are available from the manufacturer or any authorised servicing centre. For a complete list of
components, see this manual or the manufacturer’s website.
Storage for winter season
Correct long-term storage methods are essential to ensure smooth operation during
the next season. Correct storage helps extend the engine service life.
The following steps will help you ensure the maximum service life of engine components with protection against
corrosion and wear of sliding components of the engine.
The engine must be stationary and its temperature must be below 50°C. Use a damp cloth to clean the engine
from dust and dirt. Once dried up, any potential damaged spots must be treated with paint or a piece of cloth
soaked up with oil. That will prevent entry of air to the metal sheet and subsequent corrosion.
Open the fuel tank cap and check the quantity of fuel inside the tank. Long-term presence of fuel inside the tank
during storage has an adverse effect on the fuel quality. That may cause an uneven operation of the engine and
a reduced performance. Using the drain plug located on the bottom side of the carburettor, drain all petrol from
the tank and the carburettor.
DO NOT TIP THE ENGINE OVER.

5
THERE IS AN OIL LEAKAGE HAZARD! It is recommended to change the engine oil at
the end of the season. That will extend the engine service life.
Engine oil change
It is recommended to change the engine
oil after use of this equipment (according to
the Maintenance Schedule) . Switch the engine off. Let
the device cool down for a while, so its temperature
drops below 50°C. This will prevent potential burns. The
engine should remain warm still. Warm oil drains
from the engine more easily.
- Unscrew the OIL PLUG WITH GAUGE.
- Place a container with the minimum capacity of 1 litre
below the drain plug.
- Loosen the drain plug carefully.
- Let the oil drain smoothly into the prepared container.
- Once the oil stopped draining, tip the engine to the side
slightly to let the remaining oil out too.
- Clean the surroundings of the drain plug and re-tighten the drain plug in its place again.
- Used engine oil needs to be deposited at one of the authorised collection points. Engine oil is
hazardous waste!
Fill the engine with the correct amount and type of engine
oil. For engine oil specifications, see below.
- For specific filling volumes refer to the Technical data
section.
- Set the pump on a horizontal surface.
Fill the engine with approximately ¾ of the oil amount
required. Screw the plug back into the oil sump. With the
engine operation switch in the OFF (0) position, cycle the
engine by pulling the starter cord. Remove the plug, wipe the
gauge dry and check the engine oil level.
CAUTION: To get the correct reading, the gauge must be
fully screwed in place. Top up the oil to achieve the final level
between the MIN and MAX marks.
Engine oil specifications
Engine oil is one of the factors influencing the performance and service life of
the engine.
The minimum requirements for engine oil are: Viscous grade 10W30 or 10W40 with the quality rating of SF or
higher (SG, SH, SJ).
Use of engine oil grade 10W30 at ambient temperatures exceeding 27°C may result in higher oil
consumption. The engine oil level therefore requires more attention, when operating the device at such ambient
temperatures using the engine oil grade 10W30 . It is recommended to use oil grade 10W40 with the quality
rating of SF or higher (SG, SH, SJ).
The engine oil included in the delivery exceeds the minimum quality requirements highly and it will ensure safe
operation of the engine with minimum wear of their internal components under demanding operating conditions.
When topping up the engine oil, use the type and brand of oil already matching the
existing filling. Mixing of different oil types is not recommended!

Pump
Your pump features an all-metal frame to ensure its long service life and flawless operation. The pump contains
rotating parts mounted in very precise housings. It is therefore INEVITABLE that water fed into pump
remains free of any mechanical contaminants. These contaminants would grind the contact surfaces inside the
pump to increase the play between its internal components and reduce the output pressure.
DANGER
The pump generates
a very high pressure
at the outlet, making
the outlet water jet destructive to soft items. IT IS PROHIBITED to point the water stream at
humans or animals. Disrespect to this warning may result in devastating effects leading to
permanent blindness, incised wounds, amputation or even death.
CAUTION
High pressure may cause damage to soft and sensitive objects. It is not recommended to use a high-
pressure jet in a close proximity to clean rubber or tires, glass, cohesion less varnish, plasters or wood.
Too strong water jet may alter the surface texture and result in permanent change of surface finishes.
In case of any doubts, it is recommended to test the effect of pressurised water jet on a sample, where
the potential alteration of surface texture has no impact on the operability or appearance of the particular
object.
Setting the jet further from the surface of object being washed will reduce the pressure generated by
water impact and alleviate the aggressive washing effect. On the other hand, proximity of the jet to the
surface will increase the washing performance of water on the particular surface.
Safety features
The water inlet neck is provided with a safety screen. The
screen requires regular inspections with respect to potential
contamination or damage. Deposited contaminants will
reduce the flow of water supplied, further resulting in reduced
washing performance.
The screen must be replaced with a new one IMMEDIATELY,
when damaged.
Mechanical damage of internal components of
the pump due to water contamination is not
covered by the warranty!
Preparing the pump for operation
The pump is filled with operating oil. Due to the changes in oil temperature during operation and thermal
expansion, a DISCHARGE VALVE is located on the upper side of the container. In order to avoid oil leaking
from the pump during transport, the valve opening is closed by a transport plug. BEFORE FIRST USE, IT’S
NECESSARY TO REPLACE THE PLUG FOR BLACK VENT PLUG (A) WITH EXTENSION!

7
Figure A shows the pump's
vent plug, which should be
screwed onto the red
transport plug (B) located on
top of the pump housing. The
transport plug is only for
transport and the device
must not be used without
replacing it with the vent
plug!
Replace the red plug with a
black plug+ extension
(located in the bag attached
to the pump) before using it
the first time. Safety data:
The pump is filled with 15W40
class SF oil at an amount of
100ml. Before starting, it is
necessary to check the oil
level in the pump gauge
(Figure C). To check the oil
level, place the pump in a
horizontal position. Otherwise
it will not match the level of
the recorded facts. The oil
level must be within the required range during operation to ensure complete lubrication of the internal
components. Unscrew the plug and extension. Take black plug with scale, insert it into pump body opening and
check the oil level. It must be between the slots on the stem scale. Risk of permanent damage to the device!
Reinstall pump vent extension and close it with black plug with scale.The operation of a pump with a low oil level
or without oil filling will cause permanent damage to the pump and void the warranty. Check the oil level before
each use! If it is necessary to add oil in the pump, use only oil class: 15w40 SF-SJ. Do not exceed the
maximum oil level! This can result in damage to the shaft seals and oil leakage from the pump. Running
the pump without water or when it’s dry causes permanent damage to the pump and voids the warranty. Check
the water inlet before each use! Due to optimum lubrication, the pump must be at a maximum incline of 15° from
the horizontal plane.
Regulation of output water pressure
This pump allows the water outlet pressure to be controlled in the range of 80 bar to 220 bar. To change the
pressure, it is necessary to turn the controller located on the pump (Figure C - Pressure). The rule is: looking
from above and turning TO THE RIGHT (clockwise), the pressure increases and turning TO THE LEFT reduces
the pressure. Increasing the pressure increases the load on the motor and fuel consumption as well. That is
why it is suitable to adjust the water pressure according to the specific situation. Reduce the pressure to extend
the service life of the motor and pump.
Pump maintenance
The oil in the pump is replaced after the first 30 hours of operation and every subsequent 100 hours of
operation. Use 15w40 SF-SJ oil class for the change. Drain the oil from the pump by releasing the plug located
on the bottom side of the pump. It is advisable to replace the oil after use when the oil is warm, when it’s easier
to drain and impurities are dispersed in oil. After draining the old oil, screw the drain screw back slowly, pour the
oil slowly through the opening of the vent plug and at the same time check the oil level located on the side of
the pump. Take care that the oil flows slowly inside the pump, it can easily overflow. After reaching the required
oil level screw the vent plug and oil stopper back into the pump cover.

Use of self-priming detergent
The pump has the ability to automatically inject the detergent with
pressure from the container. A black nozzle for the application of
detergent is required to run this function (cat. number: ASBS0-
N0065). Only with the use of the nozzle, the pump starts to inject the
detergent itself through the hole indicated by the arrow. Connect the
supplied detergent tube to the place mark with an arrow (near the
pump high-pressure end) and immerse the other end with the
suction sieve into the diluted detergent container. Apply the
detergent by pressing the gun trigger. This configuration
doesn’t serve to create active foam. In order to create
active foam, it’s necessary to buy an aerator (cat. number: S 000-
FL002).
Pump storage for winter season
Storing the pump in areas with the ambient temperature below the freezing point may
result in irreversible damage to internal components, if not drained properly!
Excess water draining procedure:
Make sure the engine switch (p. 3 pos. C) is in the OFF (0) position.
Disconnect the supply hoses from the pump. Grasp the starter cord grip and pull the cord 5 times, as if you
were starting the engine. This action will help the water drain out of the pump through the high-pressure opening.
It is not recommended to store the pump in areas with the ambient temperature dropping below the freezing
point, since a significant change of outside temperature may result in condensation of water vapour even in
areas regularly not affected by water ingress. That may result in internal corrosion and a more significant
reduction of the service life of pump and engine.

NECESSARY TO REPLACE THE PLUG FOR BLACK VENT PLUG (A) WITH EXTENSION!
Figure Ashows the pump
vent plug that must be
screwed onto the red
transport plug located on the
top of the pump housing
(figure B). The transport plug
serves only for transport
purposes and the device
must not be used without
replacing it with the vent
plug.
(Figure C) If it’s necessary to add oil to the pump, use only the
following grades of oil: 15w40 SF-SJ. Do not exceed the maximum
oil level! This can result in damage to the shaft seals and oil
leakage from the pump. The correct procedure for checking the oil
level is given in the section: The Pump.

following rule applies: Wider spray
angle = larger area of the slide –
weaker washing effect. Insert the
nozzle into the end of the stainless
steel piston rod by pulling the ends
outer ring toward the pistol.
