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.
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.
Ignition plug
Cleaning of the ignition plug and correction of distances of
the electrodes must be performed in six-month intervals or
after 100 hours of operation. First, remove the ignition plug
shield before maintenance of the ignition plug. Then, screw
the ignition plug out using the ignition plug key. To ensure
failure-free operation, the dry ignition plug without burnt
residues must show distance of the electrodes 0.6 - 0.7
mm.
If necessary, clean the ignition plug. To remove the burnt
residues, use a fine wire brush. Distance of the electrodes
must be corrected by slight bending of the electrode. It is
recommended to use a new ignition plug in case of strong
accumulation or worn electrodes.
Checked, cleaned or a new ignition plug must be screwed
first manually to stop. Then, tighten the ignition plug using
the ignition plug key. Avoid excessive forces not to damage
the ignition plug due to torque. Finally, slide the ignition plug
shield back on the ignition plug.
Air filter
To clean the air filter, do not use gasoline or a
thinner with low flash point in any case due to fire and
explosion danger.
If the air filter is clogged, it prevents air flow to the carburettor.
To avoid operation failures of the carburettor, air filter must be
regularly checked and cleaned or replaced, if necessary.
Generally, checking of the air filter as far as clogging is
concerned is recommended before use. Cleaning is required in
three-month interval or after 50 hours of operation. When the
pump is operated in dirty or dusty environment, cleaning must
be performed in ten-hour intervals. Use a new air filter in six-
month interval or after 300 hours of operation.
Open air filter cabinet and remove the air filter before
maintenance. Wash the air filter with an inflammable thinner, if
necessary - e.g. detergent. To clean the air filter, do not use
gasoline or a thinner with low flash point in any case due to fire
and explosion danger. Let the air filter dry after cleaning.
Insert checked, cleaned or new air filter and close it again.
Do never use the pump without the air filter to avoid increased
wear and tear of the engine.
Replacement of the slide locking ring
The slide locking ring is the seal between the pump body and
the engine shaft. The ring is a component with natural wear and
tear.
If the slide locking ring is defective, water leaks between the
engine and the pump body. Demount the pump body, manual
starting device and the pump moving wheel. Then, the slide
locking ring may be replaced. Finally, carefully mount the
moving wheel of the pump, manual starting device and the
pump body.
Removal of foreign particles from the pump
Coarser particles in the pumped liquid may block the pump
body and the pump moving wheel. For this case, the pump
body can be demounted in order to remove all impurities from
the pump moving wheel.
Storing
If the machine is not used for longer time, all water in the pump
must be drained. Let the pump dry to avoid corrosion. Drain the
fuel tank and the carburettor. Cleaning and preserving of the
machine before storing is recommended. Make sure the
machine is stored in dry and frost-proof place.
Failures
Make sure no water gets in the machine.
We shall not be liable for damage due to unprofessional
repair attempts. Damage due to unprofessional repair attempts
shall void any warranty claims.
All measures for removal of defects may be performed only if
the engine is stopped.
The following list specifies some potential machine damages,
potential reasons and tips for removal. All measures for removal
of defects may be performed only if the engine is stopped. If
you are unable to remedy the defect, please contact either the
customer service or your sales representative. Overhaul repairs
may be performed by authorized personnel only. Please note
that warranty claims shall void in case of damage due to
unprofessional repair attempts and we shall not be responsible
for any consequent damage.
In case of operation failures, first check for operator error or
other cause not associated with the machine defect - e.g. no
fuel.
