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!
