IMPORTANT
Do not mix oils from different manufacturers. DOOSAN
does not endorse specific brands but recommends that
owners select quality oils whose manufacturers provide
assurance
that required standards will always be met or
exceeded.
IMPORTANT
Fluctuating daily or weekly extremes of temperature, or
operation in subzero freezing temperatures, may make it
impractical to use straight weight lubricants. Select
lubricants that are appropriate for climate conditions.
