Care And Maintenance - O.S. engine MAX-32SX-H Series Owner's Instruction Manual

CARE AND MAINTENANCE

1. The minute particles of foreign matter, that are
present in any fuel may, by accumulating and
partially obstructing fuel flow, cause engine
performance to become erratic and unreliable.
O.S. 'Super-Filters' (large and small)are available,
as optional extras, to deal with this problem. One of
these filters, Installed on the outlet tube inside your
refueling container, will prevent the entry of foreign
material into the fuel tank. It is also recommended
that a good in-line filter be installed between the
tank and carburetor.
2. Do not forget to clean the filters regularly to remove
dirt and lint that accumulate on the filter screens.
Also, clean the carburetor itself occasionally.
3. At the end of each operating session, drain out any
fuel that may remain in the fuel tank. Next, energize
the glowplug and try ot restart the engine to burn off
any fuel that may remain inside the engine.
Repeat this procedure until the engine fails to fire.
Remove the glowplug and eject any remaining
fuel/oil residue by rotating the engine with an
electric starter for 4 to 5 seconds while the engine is
still warm.
Finally, inject some after-run oil into the engine.
4.
Rotate the engine a few times by hand, to make
sure that it is free, and then with an electric starter
for 4 to 5 seconds to distribute the oil to all the
working parts.
Note:
Do not inject after-run oil into the carburettor as
this may cause the O-rings inside the carburetor
to deteriorate.
These procedures will reduce the risk of starting
difficulties and of internal corrosion after a period of
storage.
