The engine should run on a mixture of 95 unleaded petrol
and 2-stroke engine oil in the ratio of 1:40 (1L of two-stroke
engine oil for every 40L of petrol).
1. Pour the 2-stroke engine oil in a fuel mixing bottle;
2. Add petrol to 2-stroke engine oil;
3. Place the mixing bottle cap and shake carefully to mix
the oil with petrol.
Unsuitable fuels or with a different ratio than recommended
may lead to irreversible damage to the engine. Low-quality
petrol or oil can damage the engine, gaskets, hoses and the
fuel tank.
Keep the fuel mixture in proper and adequate containers in
a safe, dry, cool place protected from sunlight. Fuel mix
gets old, mix only the amount needed for a few weeks. Do
not store or use fuel with more than 30 days.
Shake the fuel mixing bottle before refuelling.
Pressure may form inside the tank, for this reason it
shall be opened carefully. Avoid direct skin contact
and inhalation of flammable vapours.
When refilling the fuel tank, do not add petrol above the
maximum level of the filler cap.
Before any maintenance or cleaning work, lay the
blower/vacuum cleaner down on a level surface,
switch off the engine and remove the spark plug cap from
the spark plug (9).
Dirty air filters reduce engine power, increase fuel
consumption and make start more difficult.
1. Move the choke lever (16) at the left side. This prevents
debris from entering the carburettor when the filter is
removed;
2. Remove the air filter cover (15);
3. Remove the filter element and blow it out with
compressed air until it is completely clean. If it does not
allow efficient cleaning or is damaged, replace it;
4. Fit the filter element and assemble the other
components in reverse order of disassembly.
The use of a dirty filter will restrict the airflow in the
carburettor affecting the pump's performance.
To ensure proper engine operation, the spark plug should
be clean and proper gapped between the electrodes.
1. Remove the spark plug cap, unscrew the spark plug (9)
with the supplied wrench and check that it is clean. If
dirty, clean the soot with a brush;
2. If the spark plug is "wet", with excess fuel, place a clean
cloth over the spark plug hole and pull the recoil starter
several times without the spark plug installed;
3. Measure the distance between the electrodes with
appropriate tools. The distance should be between 0.6-
0.7 mm. If necessary, bend the electrode until enough
clearance is reached;
4. Install the spark plug with your hand to prevent damage
to the thread and tighten it to compress the sealing
washer, using the wrench provided;
5. If the spark plug does not produce any sparks, replace
it.
A loose spark plug may overheat and cause damage
to the engine.
