LAYING-UP THE ENGINE
If the engine is not used for a fairly long time (e. g. in summer), there is a danger of
rusting. In such cases the follo wi ng precautions should be taken to protect t he e ngine :
1. Mix
the fuel with a running -in and anti-corrosion oil in 25 : 1 proportion and run
the engine on this mixture f or a short time. Use oils with a viscosity grade SAE 30
as supplied by leading oil companies (e. g. ENSIS O il 30 ava i lable fro m SHELL) .
After the last run before laying-up, the engine should be stopped at full op e rating
speed by means of the short - circuiting button, while the choke on the ca rbure ttor
should be kept closed. When the engine has stopped, close the fuel tap. These pre-
cautions will adequately protect t he crankshaft, connecting rod and main beari ngs
ago i nst corrosion.
2. To protect the cylinder and the piston, place the pist on at top dead cent er, unscrew
the sparking plug and pour 3 ... 5 cc (0 .106 ... 0.176 fl. oz.) of anti - cor rosio n oil
through the sparking plug hole. Then turn the engine 15 ... 20 tim es by means of the
sta rter and screw in the spark plug .
3. To
protect the e ngin e exte rnally , it is re commen ded that anti-corrosion o ils be
used as supplied by the leading oil companies;
for example:
Anticorit MR 5 supp lied by Mes srs. FUCHS, 68 Mannheim , G erma ny
Lubrication Oil MIL-L-644 B supplied by MOBIL OIL
Shell ENSIS Fluid 260
supplied by SHELL
RUST BAN 395 s upplied by ESSO
If the e ngine is laid up for more than six month s with fuel in the tank, separat i on of the
gasoline and oil in the fuel mixture may occur . In such cases we strongly recommend
mixing the two constituents anew by stirring, or tha't they be replac ed.
