Please, observe local requirements applicable to disposal of
used oil.
If the engine operates, do not pour engine oil in it.
Before filling of the engine oil, turn the pump off and let it
cool dow n for at least 5 minutes. During pouring of the
engine oil, the machine must be placed on a flat surface in
vertical position to avoid engine oil leak. All leaked engine
oil must be first cleaned and then start up the engine.
Do not sm oke and w ork w ith open flam e w hen
pouring the engine oil. Do not breathe vapours.
Autom atic Auto Stop activation (safety feature for low
oil level) for low oil level.
This technology automatically turns the engine off w hen the
oil level is low er than minimum required. The engine can be
restarted after sufficient quantity of engine oil is
replenished. When replenishing engine oil, adhere to all
instructions related to the engine oil and engine oil check as
specified in this guide.
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 w ithout 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 w ire 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 w orn electrodes.
Checked, cleaned or a new ignition plug must be screw ed
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 w ith 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 w ith an inflammable
thinner, if necessary - e.g. detergent. To clean the air filter,
do not use gasoline or a thinner w ith 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 w ithout the air filter to avoid
increased w ear and tear of the engine.
Replacem ent of the slide locking ring
The slide locking ring is the seal betw een the pump body and
the engine shaft. The ring is a component w ith natural w ear and
tear.
If the slide locking ring is defective, w ater leaks betw een the
engine and the pump body. Demount the pump body, manual
starting device and the pump moving w heel. Then, the slide
locking ring may be replaced. Finally, carefully mount the
moving w heel of the pump, manual starting device and the
pump body.
Rem oval of foreign particles from the pump
Coarser particles in the pumped liquid may block the pump
body and the pump moving w heel. For this case, the pump
body can be demounted in order to remove all impurities from
the pump moving w heel.
Storing
If the machine is not used for longer time, all w ater 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 w ater 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 w arranty claims.
All measures for removal of defects may be performed only if
the engine is stopped.
The follow ing 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 w arranty claims shall void in case of damage due to
unprofessional repair attempts and w e shall not be responsible
for any consequent damage.
In case of operation failures, first check for operator error or
other cause not associated w ith the machine defect - e.g. no
fuel.
