In addition, it is highly recommended to install the return
valve to prevent pressure leak after turning the pump off
and protecting the machine against damage due to
pressure surges. The return valve can be connected directly
on the pump suction connector or the suction piping input.
Installation on the suction piping input is favourable. The
suction piping can be easily deaerated by filling with water.
The suction piping input must always be located at least
0.30 m under pumped liquid level to avoid air inlet. In
addition to this, pay attention to sufficient distance of the
suction piping from soil and streams, rivers, fishponds
banks to avoid suction of stones, plants etc.
Installation of the force piping
The force piping transports the liquid to be pumped from the
pump to the consumption point. To avoid losses from flow,
using of the force piping of at least identical diameter as the
pump connector is recommended.
Fixed installation
For fixed installation, attach the gasoline engine pump to a
suitable stable supporting surface. To reduce vibrations, it is
recommended to insert an anti-vibration material, e.g.
rubber layer, between the pump and the supporting surface.
Commissioning
Installation and visual control
Flue gases of the gasoline engine pump contain
odourless toxic carbon monoxide that may result in serious
health issues and death under extreme conditions. To
protect humans and animals, the machine must not be used
in poorly ventilated places and not in closed spaces.
Generally, avoid breathing of the flue gases.
Check the gasoline engine pump with respect to
safety before use. Do not use the machine if damaged.
The gasoline engine pump may only be used in
areas without risk of floods.
For each starting of the machine, it is necessary to make
sure the pump is installed safely and in a stable position.
Always pay attention to a flat surface under the pump,
otherwise the oil low level switch may be activated and
starting is not enabled. The gasoline engine pump may only
be used in areas without risk of floods.
Select the place of the pump installation so that no
environmental damage is caused by leaked fuel or engine
oil. If used in fish ponds, pits, construction pits, rivulets,
streams and similar places, the pump must be secured
against fall.
Check the gasoline engine pump visually before use of the
pump. Pay attention to correct tightness of the bolts and
perfect condition of all connectors. Do not use the machine
if damaged.
Fuel and fuelling/engine oil
The gasoline engine pump is powered by gasoline.
Use the fuel specified in the technical data applicable to
your product.
Do not smoke and work with open flame when
refuelling. Do not breathe vapours.
Gasoline and engine oil are toxic substances. Do not
swallow gasoline or engine oil and do not breathe vapours.
Avoid any direct contact of gasoline and engine oil with skin,
eyes, and clothes.
Do not refuel if the engine is running. Turn the pump off and let
it cool for at least five minutes before refuelling. During
refuelling, the machine must be placed on a flat surface in
vertical position to avoid fuel leak. Refuel in well-ventilated area
only. All leaked gasoline must be first cleaned and then start up
the engine.
Do not smoke and work with open flame when refuelling. Do not
breathe vapours.
Check oil level before use (see Replacement/check
of oil)
Filling the pump with water or deaerating of the system
Pour water in the filling hole of the pump. Check for water leaks.
Close the filling hole again to be airtight. It is recommended -
but not absolutely necessary - to fill the suction piping with
water as well.
The gasoline engine pump is self-suctioning device. It means
that for starting, only the pump and not the suction piping must
be filled. In either way, the pump will need some more minutes
to draw the pumped liquid. Additional filling of the suction piping
will significantly facilitate and fasten the first suction. If the
suction piping is not filled with the liquid, it will be perhaps
necessary to prime the pump several times with water. It
depends on length and diameter of the suction piping.
Open potential closures in the force piping (e.g. water cock) to
release air during suction.
Operation
The gasoline engine pump must not be used with the
delivery point closed.
The pump must not be used without water for longer
period of time. Dry operation, i.e. without pumping of water,
may result in substantial damage of the machine.
The gasoline engine pump and the piping system must
be protected against freeze and weather conditions.
Flammable substances and things, easily inflammable
or explosive substances must be out of reach of the pump
during operation. Do not put anything on the engine.
If the engine is in operation, do not refuel or pour oil in it.
Turn the pump off before refuelling.
During operation, some parts of the engine pump - e.g.
exhaust or exhaust cover - are very hot. To avoid burning
injuries, touch the machine during operation and after turning it
off until cooling down on the designed points only - e.g. on
switches and handles.
