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.
