4. Then, inject some after-run oil into the engine, and
rotate the engine with an electric starter for 4 to 5
seconds to distribute the oil to all the working
parts.
Note:
5.
Do not inject after-run oil into the carburetor as
this may cause the O-rings inside the carburetor
to deteriorate. These procedures will reduce the
risks of starting difficulties or corrosion after a
period of storage.
Finally, when cleaning the exterior of the engine,
use methanol or kerosene. Do not use gasoline or
any solvent that might damage the silicone fuel
tubing.
Caution:
The rear crankshaft bearing of this engine uses a
special plastic retainer. If the front housing needs
to be heated to remove or replace the bearing, do
not allow the bearing to exceed 120˚C (248˚F),
otherwise it may be damaged and rendered
unserviceable.
PARTS REPLACEMENT
Over a long period, depending on how well
your engine is protected from the ingress of
harmful dust and grit, and other causes of
wear and tear, loss of performance may
eventually occur in the form of reduced power,
unstable idling, overheating, etc. Inspection
may then reveal that the replacement of ball-
bearings, connecting rod, etc. is called for.
Contact the O.S. distributor in your country for
replace-ment parts, or full service.
