WARNING!
The hydraulic oil will be hot after normal machine
operation. Allow the system to cool before attempting to
service any of the hydraulic components.
The hydraulic tank is pressurized. Loosen the breather
cap to allow the pressurized air to vent. After the
pressure has been released, it is safe to remove either
the fill cap or service covers.
IMPORTANT
Make sure to clean any dirt or water from the top of the
hydraulic tank, especially around the fill port and filter
ports.
Hydraulic oil change interval is 2,000 hours, only when
DOOSAN
Genuine Oil is used. If another brand of oil is
used, guaranteed change interval is 1,000 hours.
