the oil sump immediately after stopping for a long period and to warm the oil
to 100°F before refilling the sump. To prevent excessive cooling of the oil
sump and excessively high oil viscosity in cold weather, the sump may be
covered with an oil-proof lagging. Refer to the latest edition of the engine
manufacturer’s Service Letter.

Fill the fuel tanks completely. Check for water accumulating each week.

Wipe the tires with a dry cloth and treat them with a tire protector spray. Mark
the tire positions and date with chalk. Turn the wheels and check air pressure
regularly.
