•Bellmouth shroud and aluminum oil cooler are adopted to reduce noise and to improve the heat
balance.
•The space between the oil cooler and the radiator is widened for easy cleaning. (A cover is
added to the upper side.)
•The cooler check valve is placed inside the oil cooler pipe to simplify the circuit.
•The removal and installation method of oil cooler and radiator is improved, so that they can be
individually removed and installed.

•Water Separator is provided as a standard accessory (with filter function)
•Galvanized steel sheet is used for tank inner surface (lower side) for rust prevention
•The oil filler port and the strainer are improved so
that a large oil gun can be used and that stable oil

•PC-EPC valve (2 poles)
•Hydraulic oil temperature sensor (2 poles)
•Engine oil level sensor (2 poles)
•Engine water temperature sensor (2 poles)
•6-connected solenoid valve (2 poles)
•Governor motor (3 poles, 4 poles)

17. Changes in Hydraulic Tank
•Change of Tank Capacity 230 Ltr ==> 200 Ltr
•Adoption of Hydraulic Oil Temperature sensor
•Return filter is replaced with a compact high performance one to lengthen the replacement frequency
500 h ==> 1000 h
•When the return filter is replaced, the filter lower face is above the oil line and the filter can be replaced without
spilling oil
•Preparation of special filter for flushing

18. Return Filter
Posture for Replacing Filter
Micro glass (high performance filter medium) is
adopted to use the filter for a long time and to make
the size small

The filter lower face is above the oil line
Changes in Hydraulic Tank
Since the fiber of the high performance filter
medium is very thin and has lots of holes, the dirt
capacity is improved

19. Hydraulic Circuit Flushing Procedures
1. Replacement of return filter (Standard item --> Flushing item)
(1) Replace the element with a flushing one (absolute filter gain size: 6µ)
16
Changes in Hydraulic Tank
2. Flushing of Hydraulic Circuit
After installing the flushing element, change the working mode to the "E" Mode and then
execute the following:
(1) Idle the engine at a low speed and keep the lever at the neutral position for 30 minutes.
(2) Idle the engine at a medium speed and keep the lever at the neutral position for 30 minutes.
(3) Idle the engine at the high speed (1800rpm) and select Boom RAISE, Boom LOWER,Arm OUT, Arm IN,
Bucket DUMP and Bucket Digging with the lever four times (holding the lever at each operation for 1 minute
to 1 minute and 30 seconds)
3. Precautions
(1) Be sure to keep the removed standard items (element, valve and strainer) in order because they are used
again after the flushing.
(2) After the flushing, dispose of the special element for flushing. But keep the blind plate in order because it is
used again for the next flushing
When replacing the element, lift it slowly so that contaminants adhered to the element
do not drop in the case. Remove contaminants left in the case by hand.
(2) Replace the relief valve and the strainer with the plate (blind plate) shown on the right
side.

viewing the liquid crystal screen. When
the work equipment and attachments
like crusher are operated at the same
time, this function reduces flows on the
attachment side automatically for
operating the work equipment smoothly.
