●
Store the oils and fuel indoors in order to
keep them free from water, dust and other
foreign substances.

To store the barrel of oil or fuel for a
long period, it is necessary to place the
barrel with its opening facing the side
in order to prevent intake of moisture.
If you have to place the barrels outdoors,
cover them properly with waterproof can-
vas or take other protective measures.
●
To prevent deterioration of oil or fuel during
long-term storage, use the oil or fuel that
has been stored earlier than others.

lter elements shall be replaced more fre-
quently according to the sulfur content in
