6. Replacement of Plastic Annular Ring
The EVO-SYSTEM Engine (Male) annular
ring can be replaced if damage or wear is
detected.
To replace the annular ring:
• Remove the damaged ring by carefully
cutting through it with a sharp craft knife.
• Clean away any dirt, debris or Plastic
residue from the annular ring mounting
flange
• Position the Plastic ring onto its flange and
push it fully home so that it lies flush
against the engine casing.
Note: The Plastic ring is not 'handed' and can
fit onto the flange either way round.
• Check the installation.
7. Uni-coupling Clutch
Drive from the engine to the accessory is
transmitted by a 12 toothed sprung loaded
dog clutch coupling. This should be kept
clean and the teeth regularly inspected for
wear (preferably at every connection or
disconnection). Any debris or dirt etc that
becomes lodged between or on the teeth
could cause premature wear and so should
be removed as soon as possible.
Clean with a slightly damp soft cloth
(a pipe-cleaner or small brush may be useful
to access the spaces between the teeth).
Lightly spray the metal parts of the Uni-
coupling with a high quality Silicone Spray
Lubricant as detailed in the Maintenance
Summary Chart. Avoid spraying rubber
components.

LONG TERM STORAGE
If your EVO-SYSTEM Engine is not going to
be used for a period of 4 months or more
(e.g. over the winter period) the operator
should consider preparing it for long term
storage. This will keep the engine in optimum
condition for re-commissioning when
required.
• Drain all the fuel from the fuel tank and
carburettor into a suitable approved
container.
• A drain plug can be found underneath the
carburettor float bowl. (Fig. 26)
• Replace the drain plug when all the fuel has
been removed.
• Remove the spark plug.
• Pour approximately one tablespoon of
clean engine oil into the spark plug hole.
• Ensure that the engine ignition switch is in
the 'OFF' position.
• Gently pull the recoil starter a few times.
• Replace the spark plug.
• Gently pull the recoil starter until resistance
is felt (this will mean that the piston is on its
compression stroke with both valves
closed). Stop pulling the recoil starter.
• Store the engine in a secure, dry and well
ventilated location, under a cover to prevent
dust, debris etc from settling on the
machine.
