DAEWOO recommends infrared analysis (in
conjunction with wear metal analysis) of used oil in
determining the effectiveness of oil TBN and acid
neutralization.
For fuel with sulfur exceeding 1.5% by weight, use
oil with a TBN of 30 and reduce the oil change
interval by one half. Also, infrared analysis and
wear metal analysis should be used to establish oil
change intervals.
Periodically request fuel sulfur content information
from your fuel supplier. Fuel sulfur content can
change with each bulk delivery.
Gasoline Specifications
Only unleaded gasoline should be used for
DAEWOO forklift trucks.
The gasoline in which methanol is contained is not
recommended. The gasoline in which ethanol is
contained is not recommended, either.
It is recommended to use gasoline fuel that has
octane number 87, to prevent knocking trouble.
LP-Gas Specifications
LP-Gas is “liquefied petroleum gas”. The exact
composition of LP-Gas varies slightly between
different parts of the country and different refineries.
HD5 is recommended for DAEWOO forklift trucks.
Remember LP-Gas is heavier than air and will sink
to the lowest spot possible. Avoid areas near floor
drains or lubrication pits where escaped fuel may
collect.
