of the combustion engine or from accidents caused by device’s rotating part.
Scope of Delivery
The scope of delivery is shown on the packaging or on the order of the goods. When unpacking, check the completeness of
the contents. Please inform the seller if any parts are missing or if you find any damage caused by transport.
Additional Requirements
A fabric-reinforced water hose with a diameter of at least 1,5” (38mm) for connection to the outlet terminal of the pump. A
suitable hose with a reinforcement with a diameter of at least 1,5 "(38mm) is required at the inlet.The maximum length of the
outlet hose is 150 metres. Basic rule: The longer and thinner the hose, the smaller the water flow at the end of the hose.
Engine oil.
Assembly
The device is assembled in the manufacturing plant. Attach the handle according to the enclosed instructions. Take the pump
out of the box and place it on a flat surface. Take the hose ends, clamping clips, suction strainer from the transport bag (Suction
hose has to be purchased.). Put the clamping clip onto the hose and then insert the upper part of the suction strainer into the
hose. Take care not to damage the plastic body of the strainer by using excessive pressure! Tighten the clip on the suction
strainer shank to prevent it from falling out of the hose. Assemble the bottom and top of the suction strainer by pushing the
two parts together. Put the second clamping clip on the other end of the hose and insert a metal terminal for clamping the
pump to the suction hose. Tighten the clip to prevent the hose from falling out and the air from entering the suction section.
It’s necessary to attach a hose terminal on the discharge side of the pump according your needs. The leakage in this section
will result in poor pump performance and excessive blade wear. Don’t forget to attach the seal to the terminal. In the
next step, it’s necessary to fill the engine with engine oil according to the instructions in the ENGINE section (p. 3) and pour
fresh petrol with an octane rating of 95 into the tank.
The standard supplied terminals
have the following dimensions:
WP15- 1,5”/38mm
Putting into Operation
WARNING Don’t start the pump without pre-filling the pump with water. Running a dry pump will damage the sealing
element on the shaft. When starting the pump, proceed as follows. Connect the suction hose with the suction strainer to
Flange 1 on the front of the pump. It’s essential that the joint between the hose and the pump is tight and there is no air intake
around the bearing surfaces. Then connect the outlet hose for pressure water to Flange 2. In the next step, it’s necessary to
pour water into the pump. Remove Cap 3 turning it to the left (anti-clockwise). Pour clean water into the pump up to the level
of the mouth of the cap hole. The water won’t flow out as the backflow valve prevents water from flowing through the suction

3
pipe. Subsequently, put Cap 3 back into the pump turning it to the right (clockwise) and tighten it by hand. Check the tightness
of Drain Cap 4. Excessive tightening with pliers may result in damaging the cap. Immerse the suction hose suction strainer
into the water source needing to be pumped. After pumping is completed, any water remaining inside the pump must be
drained by unscrewing Cap 4. Storing the pump filled with water over a long period of time will cause internal corrosion on the
pump blades and scale on rotating parts, therefore, reducing the pump’s life.
Start the engine and adjust the engine speed with the throttle. Refer to the ENGINE section for more information on
starting the engine. It’s necessary for the engine to run at higher revolutions until the pump takes in water from the
source. The suction process can be seen through a transparent suction hose. If the pump doesn’t exert pressure
within 30 seconds after starting the engine, turn-off the engine and follow the Troubleshooting instructions.
CAUTION: Draining water from a depth of more than 3 metres may require water replenishment to the pump as
described in the Putting in Operation section.
Dry running for more than 60 seconds will cause pump damage! WARNING: If the pump
takes in air, it’s necessary to remove the leakage on the suction pipe and repeat the
whole process of pouring water into the pump. Damage caused to equipment due to non-
compliance with this instruction the warranty will be deemed invalid.
Engine
The engine MUST be filled with the correct amount of engine oil before its first
commissioning. For specifics refer to the Technical data section. 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 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.
Push the engine switch C into the ON (I) position.
Shift the speed control lever B into the position.
Shift the choke control lever A into the CHOKE (OFF)
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, repeat the starting
process by pull the starter grip again.
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 (ON) position SLOWLY.
ENGINE SHUTDOWN
Engine shutdown comprises the following steps
Shift the engine speed control lever 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 switch C into the OFF position.
CAUTION 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.

During operation, in rare cases, protective metal covers may become loose due to vibration. It’s necessary to
tighten these components as the long-term effect of vibrations on the loosened cover causes damage to the
mounting holes. If the exhaust, air filter or cooling fan protective cover is damaged, these parts have to be replaced
by original parts as this is the only case where maximum safety can be guaranteed.
Spare parts are available through the manufacturer or a certified service centre. A complete list of components is
provided in this instruction manual or on the manufacturer's website.
Winter Storage
Proper long-term storage is crucial to achieving seamless operation in the following season. Extend the
life of the engine by storing it properly.
The following steps will provide you with the maximum protection of engine components against corrosion and
wear of sliding parts of the engine. The engine must be kept in a room and engine temperature must be less than
50 °C. Use a damp cloth to clean the engine from dust and dirt. After drying, treat any damage with paint or cloth
saturated with oil. This prevents the air from entering the sheet metal and subsequent corrosion.
Open the fuel tank cap and check the amount of fuel in the tank. The long-term presence of fuel in the tank during
storage has a bad influence on fuel quality. This can result in irregular engine running and reduced power. Remove
petrol from the tank and carburettor through the drain screw located on the bottom of the carburettor. DO NOT
OVERTURN THE ENGINE.
THERE IS A RISK OF OIL LEAKAGE! It’s recommended to replace the engine oil at the end of the season.
This extends the life of the engine.
Engine Oil Replacement
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 must be delivered to one of the specified 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 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 Specification
Engine oil is one of the main factors affecting engine performance and life.
The minimum requirements to be met by the oil are: viscosity class of 10W30 or 10W40 with quality level of SF
and higher (SG, SH, SJ).
The use of 10W30 engine oil at temperatures higher than 27 °C can lead to increased oil consumption. Therefore,
it’s necessary to pay extra attention to the oil level if the device is operated at these temperatures with 10W30 oil.
It’s recommended to use 10W40 oil with the quality level of SF and higher (SG, SH, SJ).
The engine oil supplied exceeds the minimum quality requirements and ensures safe engine operation with
minimal wear on inner parts under demanding operating conditions.
If it’s necessary to add engine oil, use only the same oil type and brand as the one already in the engine.
Mixing different types of oils isn’t recommended!
Pump
Your pump is an all-metal structure to guarantee long service life and trouble-free operation. The pump contains
moving parts with a very precise fit. Therefore, it’s NECESSARY that water supplied to the pump is free from
major mechanical impurities. The dirt meshes the bearing surfaces in the pump and increases the play
between the inner parts and reduce the outlet pressure.
DANGER
The pump produces high pressure at the outlet and as a result splashing water may have devastating
effects on soft objects. It’s FORBIDDEN to direct a stream of water towards humans or animals. Failure
to obey this warning may have devastating effects, resulting in permanent blindness.
CAUTION
High pressure can cause damage to soft and sensitive objects. It isn’t recommended to use a high-
pressure water stream from the immediate vicinity for cleaning glass, non-coherent paint and plaster.
Strong water flow can change the surface structure which may be permanent. In case of doubt, it’s
advisable to test the pressure water action on a sample where potential damage to its surface won’t affect
the functionality or appearance of an object.
Mechanical damage to inner parts of the pump due to contaminated water isn’t covered by the warranty!
Rubber and plastic sealing elements are used in the pump. For this reason only water with a maximum
temperature of 40 °C can be used in the water supply.
Ensure that the water level in the container from which the water is taken is as high as possible to supply water
into the pump. Small difference in the levels will make it easier to draw the water, therefore, reducing the risk of
cavitation – a phenomenon that occurs when air bubbles begin to bubble out of the fluid. This can happen in the
inside the pump if the vacuum at the inlet is too high – harder suction.
Therefore, use a hose with the largest diameter and as short as possible for suction purposes. Follow the
instructions on page 2 (Putting into Operation).
Winter Pump Storage
Storing the pump in rooms where the ambient temperature is below freezing point can cause irretrievable
damage to the inner components if the pump isn’t drained properly!
Procedure to drain residual water from the pump: Switch off the engine. After pumping is completed, pump water
must be drained by unscrewing Cap 4 (see pages 2-3 Putting into Operation). Storing the pump filled with water
for a long time will cause internal corrosion of the pump blades and scale on rotating parts, therefore, reducing
the pump’s life.
Disconnect the supply hoses from the pump. Hold the starting cord handle and pull the cord 5 times as if you are
starting the engine. By doing so, the water from the inner parts of the pump flows through Cap 4. After draining
the water, screw the cap back into the pump body.
It isn’t recommended to store the pump in rooms where the temperature drops below freezing point as a significant
change in outside temperatures can cause water vapour condensation even in areas where water is otherwise
not available. This can cause internal corrosion and significantly shorten the life of the pump and the engine.
