CARE AND MAINTENANCE
To ensure that you obtain long life and peak performance
from your engine, observe the following.
Avoid running the engine under dusty conditions.
If necessary, lay a sheet of plywood or hard-board
in front and under the nose of the model when
starting the engine.
Foreign matter in the fuel can cause the
carburettor jet to be partially clogged.

Therefore:
rinse out the fuel tank with methanol or fuel before
installing it.
Install a fuel filter in the fuel line between tank and
carburettor.
Install a fuel filter in the outlet of your squeeze
bottle, or in the pump inlet if you use a manual or
electric pump.
do not leave your fuel container open needlessly.
check filters periodically and clean them when
necessary.

Do not leave raw fuel in the engine at the
conclusion of a flying session: it may cause
corrosion. The best practice is to disconnect the
fuel line from the carburettor while the engine is
running. Remaining fuel in the tank should also be
drained off.
Clean the exterior of the engine with a clean cotton
cloth.If this is not done, oil and dirt will burn onto
the outside of the engine each time it is run and
the engine will soon become blackened.
If the engine is not in use for a while (more than
two months) remove the glowplug and rinse out
the interior with kerosene (not gasoline), by
rotating the crankshaft. Shake out residue, then
inject light machine-oil through the plug hole and
carburettor intake, again rotating the shaft to
distribute the protective oil to all working parts.
Gasoline, thinner, kerosene and light machine oil
cause swelling and deterioration of plastic parts,
"O" rings and fuel tubing. Use methanol for
cleaning these engines.
Avoid unnecessary dismantling of your engine.
