DOOSAN 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.
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 DOOSAN 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.
Composition of HD5
Propane (C3H8) 90.0 %
Propylene up to 5 %
Butane (C4H10) 2.0 %
iso-Butane 1.5 %
Methane (CH4) 1.5 %
Total 100 %
