REMOVAL / INSPECTION /
MAINTENANCE / REPLACEMENT
OF THE SPARK PLUGS
•
ATTENTION
y The generator has 2 spark plugs because it has an
engine with two cylinders. A spark plug is located
on both sides of the generator.
 For the problem-free starting and operation of the
engine, the electrodes of both the sparks plug must
not be clogged, both the spark plugs must be correctly
set and installed.
•
WARNING
y The engine and the exhaust pipe are very hot while
the generator is running and for a long time after it has
been turned off. Therefore, be very careful to avoid bur-
ning yourself.
1. Take off the spark plug connector (fig. 16) on both
spark plugs and remove the spark plugs using the
correct wrench key.
2. Visually inspect the exterior appearance of the
spark plug.
y In the event that the spark plug has clogged electrodes,
file them using sandpaper or steel brush if necessary
(fig. 17).
y If the spark plug is visibly significantly clogged or if the
insulator is cracked or it is peeling, replace the spark
plug with a new one (the spark plug type is specified in
table 1).
Using a gauge, check that the distance between the
electrodes is 0.6-0.8 mm and that the gasket ring is in
order (fig. 18).
3. Then screw the spark plug back in by hand.
4. Once the spark plug is screwed in, tighten it using
a spark plug wrench to compress the gasket ring.
NOTE
y After hand tightening the new spark plug, it is necessa-
ry to turn it by approx. 1/2 a rotation to compress the
gasket ring. If this is a reused older spark plug, it is only
necessary to tighten it by 1/8 to 1/4 of a rotation.
 A spark plug is a consumable good, and its wear and
tear is not covered by the warranty.
•
ATTENTION
y Make sure that the spark plug is well tightened. An
incorrectly tightened spark plug clogs and heats up sig-
nificantly and could seriously damage to the engine.
5. Place the spark plug connector back on to the
spark plug so that it clicks in place.

SPARK PLUG FUNCTION TEST
(GENERATES A SPARK)
•
ATTENTION
y First ensure that there is no spilled petrol or other
flammable substances in the vicinity. When testing
functionality, use suitable protective gloves. When wor-
king without gloves there is a risk of injury by electrical
shock! Before removing the spark plug, make sure that
the spark plug is not hot!
1. Screw the spark plug out of the engine.
2. Seat the spark plug into the spark plug connector.
3. Move the power switch to the "0N" Position.
4. Hold the thread of the spark plug against the body
of the engine (e.g. on the cylinder head) and pull
on the handle of the pull starter.
5. If there is no sparking, replace the spark plug with
a new one. In the event that no sparking occurs
even with the new spark plug, it is necessary
arrange a repair at an authorised service centre.
If the sparking is in order, reinstall the spark plug
and continue starting the engine according to the
manual.
If you are unable to start the engine even after this, have
the repairs performed at an authorised service centre for
the HERON® brand.
•
ATTENTION
y If the spark plug that is used is generating sparks when
tested but the engine nevertheless fails to start, try
replacing this spark plug for a new one.
MAINTENANCE OF THE PETROL
FILTRATION STRAINER IN THE REFILL
NECK OF THE FUEL TANK
1. Screw open the fuel cap and remove the strainer
inserted in the neck of the fuel tank (fig. 19). Rinse
the strainer in any non-flammable cleaning agent
(e.g. detergent solution), or it is also possible to
use a brush with plastic bristles and then rinse the
strainer under clean water and allow it to dry tho-
roughly so that water does not come into contact
with petrol. In the event that the strainer is excessi-
vely soiled, replace it with a new original one.
2. Return the cleaned strainer back into the neck of
the fuel tank.
3. Put the fuel tank cap back on and tighten it firmly.
