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.

PARTS REPLACEMENT
Over a long period, depending on how well
your engine has been protected from the
ingress of dust and grit and other causes of
wear and tear, loss of performance may
eventually occur in the form of reduced
power, reluctant starting, unstable idling, etc.
Having checked that this is not due merely to
the need to readjust the valve clearances (for
which an O.S. Valve Adjustment Kit - Code
No. 72200060 - is available) inspection may
then reveal that the replacement of some
parts may be called for.
Contact the O.S. distributor in your country
for parts or full service. See pages 21 of this
booklet for details of parts.

CARE & MAINTENANCE
At the end of each operating session, drain
the fuel tank, then energize the glowplug and
try to re-start the engine to burn off any fuel
that may remain inside. Repeat this
procedure until the engine fails to fire. Then
remove the glowplug and drain off any
residue while the engine is still warm.
Inject some corrosion-inhibiting after-run oil
and rotate the crankshaft to distribute oil to
the working parts. Do not inject such oil into
the carburettor, however, as it may cause
deterioration of the carburettor's O-ring seals.
Apply a little lubricating oil to the rocker shaft
and rocker arms.
●
Note!
These maintenance procedures will reduce
the risks of corrosion or starting difficulties
after a period of storage.
