Maintenance Of The Petrol Filtration Strainer In The Refill Neck Of The Fuel Tank; Purging The Carburettor; Cleaning The Setting Tank Of The Fuel Valve; Maintenance Of The Exhaust Pipe And Spark Catcher - HERON 8896230 Bersetzung Der Ursprünglichen Bedienungsanleitung

1. Take off the spark plug connector (fig. 13A) and
remove the spark plug using the correct wrench
key (fig. 13B).
2. Visually inspect the exterior appearance of the
spark plug.
y In the event that the spark plug has clogged electro-
des, file them using sandpaper or steel brush if
necessary (fig. 14).
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. 15).
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 neces-
sary 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 significantly 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.
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. 16). 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 even 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.

PURGING THE CARBURETTOR

1. Shut off the petrol supply to the carburettor using
the fuel valve (position 0 on the pictogram).
2. Place an appropriate container underneath the
drain bolt of the carburettor and then screw out
the drain bolt of the carburettor and drain the
dirty material into the prepared container (fig. 17).
•
ATTENTION
y Petrol will start flowing out of the loosened screw.
Purge the carburettor ideally outdoors since petrol
fumes are damaging to health. Likewise, use appropri-
ate waterproof protective gloves to prevent the skin
from being sprayed with petrol. Petrol is absorbed
through the skin into the body! Purge the carburettor
away from any sources of flames and do not smoke.
3. To purge the carburettor, open the fuel supply
using the fuel valve for a few moments to allow any
dirty material to flow out into a container. Then
close the fuel valve again to shut off the fuel supply.
4. Then screw the carburettor drain screw with the gasket
washer back in and tighten firmly. After opening the
fuel valve, check that no fuel is leaking around the bolt.
If fuel does leak, tighten the mud bolt, or if neces-
sary replace the seal washer of the bolt.
•
ATTENTION
y Hand the petrol with the dirty material from the carbu-
rettor in an enclosed container to a hazardous waste
collection facility. Do no pour it down the drain, on soil
or throw it out with communal waste.
•
ATTENTION
y The user can perform the carburettor purging operation
using the carburettor mud bolt themselves, however,
any work on the carburettor may only be performed by
an authorised service centre for the HERON® brand.
y The air-fuel ratio and the carburettor are set by the manu-
facturer and it is not permitted to make any changes to
these settings. Any amateur tampering with the carburet-
tor settings may result in serious damage to the engine.
CLEANING THE SETTING TANK
