Page 11: Outline Of Hybrid System
This machine is equipped with the hybrid system consisting of an electric motor and the diesel engine to reduce fuel consumption. If they need to be removed, ask your Komatsu distributor. CONFIGURATION OF HYBRID SYSTEM The hybrid system of this machine has high-voltage components such as high-voltage electric wirings which connect between the devices and the hybrid devices of approximately 650 V (motor-generator, capacitor, inver- ter, electric swing motor).
Page 12: Engine Technology To Conform Exhaust Gas Emission
Catalytic Reduction (SCR) to conform EU Stage IV emission regulation in the European Union. • Komatsu Diesel Particulate Filter (KDPF): A device which captures diesel particular matter or soot in the exhaust gas to purify exhaust gas. If soot is accumulated to a certain level in the filter, a purification process to burn the soot is performed automatically to keep the filtering performance of KDPF high.

Page 417 MAINTENANCE MAINTENANCE PROCEDURE Remove the cover (3) on the bottom of the fuel tank. (if equipped) Turn the valve (1) at the bottom of the fuel tank to CLOSE position (S). Open the door on the right side of the machine. Place a container under the fuel prefilter cartridge (2) to catch the fuel.

Page 419: Method For Replacing Def Tank Breather Element
If the machine is operated without DEF tank breather element attached, or with the element other than Komatsu genuine parts, foreign materials may enter into DEF pump and DEF injector which will cause failure of the machine. Never operate the machine without DEF tank breather element at- tached, nor use the element other than Komatsu genuine parts.

MAINTENANCE MAINTENANCE PROCEDURE Set the TOP mark at the top with the line running on TOP mark and plug (P) perpendicular to the ground surface. Place the oil container to receive oil under plug (P). Remove plugs (P) and (F) by using the handle, and drain oil.
Page 422: Method For Checking And Releasing Nitrogen Gas Charge Pressure In Accumula- Tor (For Control Circuit)
• Do not hit or roll it, or subject it to any impact. • When disposing of it, the gas must be released. Ask your Komatsu distributor to have this work per- formed. NOTICE If the nitrogen gas charge pressure in the accumulator is low and operations are continued, it becomes impossible to release the remaining pressure inside the hydraulic circuit if a failure occurs on the ma- chine.
Page 423 MAINTENANCE MAINTENANCE PROCEDURE Hold the work equipment in the maximum reach posture (arm fully OUT, bucket fully DUMP) at height (A) 1.5 m from the ground. Perform the following procedure within 15 seconds. After the engine stops, the accumulator pressure decreases gradually. You can check only just after the en- gine stops.
Page 424 If the work equipment does not go down or stops in midway, the charged pressure of the gas in the accumulator for the hy- draulic circuit has probably dropped. Ask your Komatsu distrib- utor for inspection. This completes the inspection. After completion of the inspection, set the lock lever to LOCK position and turn the starting switch to OFF position.
Page 425: Method For Checking Alternator
If the engine is started frequently, have this inspection performed every 1000 hours. METHOD FOR CHECKING AND ADJUSTING ENGINE VALVE CLEARANCE Special tools are necessary for inspection and maintenance. Ask your Komatsu distributor to perform this work. METHOD FOR REPLACING KCCV FILTER ELEMENT WARNING After the engine has been operated, all the parts are still very hot.
Page 426 MAINTENANCE PROCEDURE MAINTENANCE NOTICE • If the engine is operated without the filter element, the turbocharger and aftercooler become dirty and their performance will lower and that can cause engine problems such as overrun caused by suction of oil. Therefore, never start the engine without the filter element. •...
Page 427 MAINTENANCE MAINTENANCE PROCEDURE There may be oil accumulated or sticking in the case and element. Take care not to spill the oil when replacing the element. REMARK When the ambient temperature is low, water or emulsified matter may stick to the inside of KCCV because of con- densation of water vapor in the blowby gas.
Page 428: Method For Replacing Def Filter
Komatsu recommends using Komatsu genuine parts for replacement parts. • If the machine is operated without the DEF filter attached, or with the filter other than Komatsu gen- uine parts, foreign materials may enter the DEF pump and DEF injector which will cause failure of the machine.
Page 429 MAINTENANCE MAINTENANCE PROCEDURE After the engine is stopped, the DEF system devices automatically purge the DEF in the DEF injector and DEF pump and return it to the DEF tank to prevent malfunction of the devices caused by freezing of the DEF or dep- osition of urea.
Page 430 MAINTENANCE PROCEDURE MAINTENANCE Check that the filter removal tool (3) is fully inserted to the end. Insert the filter removal tool to the end where you cannot thrust it in any further. Turn the filter removal tool (3) in reverse, and remove the filter (6).
