MAINTENANCE
Every 2000 Hours
Replacing the Hydraulic Oil and
Cleaning the Suction Strainer
WARNING
¡ ¡
¡ ¡
¡
Stop the engine and allow the machine
to cool down before performing
maintenance.
• The engine, hydraulic lines and many
other parts of the machine are hot
directly after the engine is stopped.
Touching these parts will cause
burns.
• The hydraulic fluid is also hot and
under high pressure.
Be careful when loosening caps and
plugs. Working on the machine under
these conditions could result in
burns or injuries due to the hot oil
spurting out.
¡ ¡ ¡ ¡ ¡
Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• Gradually loosen the vent plug to
relieve tank pressure.
• When removing plugs or screws or
disconnecting hoses, stand to the
side and loosen slowly to gradually
release the internal pressure before
removing.
1. Slew 45
°
clockwise and set the machine
to the hydraulic oil level inspection posture.
Refer to page 105 “Inspecting the
Hydraulic Oil Level and Replenishing”.
2. Slowly turn the vent plug (1) to relieve tank
pressure, then remove.
3. Loosen the bolts and remove the cover
(2).
4. Remove the return filter (3).
5. Place a pan for catching the spent oil
under the drain plug (5).
6. Loosen the drain plug (5) and drain the

strainer (7).
12. Install the cover (2) and the flange (6).
13. Install the hose (8) to the flange (6).
14. Tighten the drain plug (5).
15. Insert hydraulic oil through the hole in the
vent plug (1), adding hydraulic oil to
between the upper limit (H) and lower
limit (L) of the sight gauge (4).
16. Follow the procedure next page
“Bleeding the air” to bleed the air from
the hydraulic oil circuit.
17. Set the machine to the hydraulic oil level
inspection posture and inspect the level
once the temperature of the oil has
dropped.
Refer to page 105 “Inspecting the
Hydraulic Oil Level and Replenishing”.
18. Pressurize the hydraulic tank.
