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.
Starting of the engine
Open the gasoline cock to turn the engine on (Fig. A/19).
Set the ignition breaker (Fig. A/10) to ON position, set the
saturator lever (Fig. A/15) in Start position and the power
controller (Fig. A/12) to Full throttle position. Then, pull with
the starting rope (Fig. A/11) several times until the engine
starts. Then, slowly set the saturator lever (Fig. A/15) in the
operation position. As soon as the engine starts, suction
commences. Now, leave the power controller (Fig. A/12) in
the Full throttle position. If the liquid is drawn equally or
without any air, the suction is interrupted and the system
deaerated. Now, set the power controller (Fig. A/12)
according to individual requirements.
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.
During first 20 hours of operation, the brand new engine must
not be fully loaded. Operation at 2/3 of possible output
performance is recommended. Full throttle operation is now
permissible for short term only up to 10 minutes - e.g. for
starting due to suction operation.
Turning the engine off
Set the power controller (Fig. A/12) to Idle Throttle position and
set the ignition breaker (Fig. A/10) to OFF position. The pump
input is fitted with a valve that prevents leaking of water from
the pump after it is turned off. Stopping of the back flow will
result in shorter time for re-suction during the next start.
Therefore, the pump must not be primed again during restart.
Decommissioning
Transport of the pump with the fuel tank filled is not
approved.
Discharge water in the pump from the relevant discharge hole
after use. Let the pump dry well to avoid damage due to
corrosion. Water entrapped in the pump may cause damage if
frozen.
If the device is transported, all fuel must be discharged.
Transport of the pump with the fuel tank filled is not approved.
Care and maintenance
If possible, turn the engine off, remove the spark plug
shield and let the engine cool down before maintenance. If the
engine must be on during maintenance, provide sufficient
ventilation because the exhaust fumes are toxic.
Regular maintenance and diligent care reduce the risk of
potential operation failures and contribute to improved lifecycle
of your machine. The engines consist of the up-to-date
technology and many rotary components exposed to substantial
mechanic, thermal as well as chemical effect of environment
and the combustion process. Use of correct, high quality and
clean operation liquids - fuel and engine oil - is prevention
against damage to the engine and operation failures.
Abrasive substances in the delivered liquid, such as sand,
increase wear and tear and reduce total performance.
Installation of a pre-filter is highly recommended for pumping of
liquids with abrasive substances. The recommended
accessories filter sand and other similar substances from the
liquid effectively and reduce wear and tear and improve
lifecycle of the pump.
Oil check and replacement
Check for oil level before starting.
Oil must be replaced at least annually. Engine oil deteriorates
during this period despite the fact the engine is not almost used.
For oil replacement, discharge old oil and pour new oil in the
filling hole in the oil tank (for type and quantity of oil - see
Technical data). Excessive amount of oil has negative effect as
well - (see quantity of oil - Technical data).
Diligent care includes oil level check before use. Use prescribed
oil dipstick for inspection. During the oil level check, the
machine must stand flat, turned off and cooled down. Make
sure oil level does not exceed maximum quantity and fall under
