Inspection, Maintenance and Adjustment

Hydraulic Oil Exchange and Suction 

Strainer Cleaning

NOTE:

Based on the type of excavating being completed, 
the working conditions (extremely hot or dusty) and 
the extra front end attachments being used (hydraulic 
breaker, etc.), the hydraulic fluid will need to be 
changed more frequently.

1.

Position the machine on firm, level ground. Swing upper 
structure perpendicular (90°) to tracks. Lower boom and 
position bucket on ground as shown in Figure 101.

2.

Set safety lever on "LOCK" position.

3.

Shut down engine.

4.

Release pressurized air from hydraulic tank by lifting 
breather cap (1, Figure 104).

Figure 100 

ARO1760L

 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. Lift 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.
