LAYING-UP THE ENGINE
If the engine is not used foro fairly long time (e. g. in summer), ther e is a danger of
rusting. In such cases the following precautions sho ul d be taken to protec t th e engine:
1. Mix the fuel with a running-in and anti-corrosion oil in 25 : 1 proportion and run
the engine on this mixture for a short time. Use oils with a viscosity grade SAE 30
os s upp lied by leading oil compan ies (e. g. ENSIS Oil 30 available from SHELL ).
After the last run before laying-up, the e ngine should be st opped at fu ll opera ting
speed by means of the short-circu iting button, while t he choke on the carbu rett or
sho uld be kept clo sed. When th e e ngine ha s st opped , cl ose the fuel tap. Th es e
precaution s will adequately protect the crankshaft , connecting rod and main bear-
ings against corros ion.
2. To
protect the cylinde r a nd the piston , pl ace the pis to n at top dead center , unscrew
the sparki ng plug and pour 3 ... 5 cc (0.106 ... 0.1 76 fl. oz .) of anti-corrosion oil
through the spark ing plug hole . Then iurn the 0 ngine 15 ... 20 times by means of the
s tarter and sc rew in the spark plug.
3. To protect the engi ne exte rn ally, it is reco mmended ihat anti-corrosion oils be used
as supplied by the leadi ng oil compani es;
for example :
Ant i corit MR 5 s uppli ed by Messrs. FUCHS, 6800 MANNHEIM , GERMANY
Lubrication Oil MIL-L-644 B supp l ied by MOBIL O IL
Shell ENSIS Fluid 260 su pplied by SHELL
RUST BAN 395 su ppl ied by E SSO
If the engine is la id up for more than six month s with fue l in the tank , se para tio n of
th e gasoline and oil in the fuel mixture may occur. In such c ases we strongly recom -
mend mixing the two c onst ituent s an ew by st irring , or that they be replaced .
