High-Performance Return Filter |
|
 |
| The hydraulic oil change interval is 5,000hours, and the return filter change interval is 2,000hours. One high performance return filter keeps the same level of filtering effect as a nephron. |
| ●Hydraulic oil change: 5,000 hours |
| ●Life of filter: 2,000 hours |
| ※ The oil and filter change interval depends on the working conditions. |
|
|
 |
| The High-Performance Return Filter is made more precisely to condense the Nephron filter function. |

Engine Oil Drain Coupler |
|
|
| The engine oil pan is provided with a drain coupler. This makes easier to do drain work and preventing oil from spattering with an attached drain hose.

EMS (Easy Maintenance System) as Standard |
|
|
| SUMITOMO's new improved EMS keeps the pins and bushes fully lubricated at all times and prevents rattling. This system significantly extends the service life of the pins and bushes.
|
| The interval of greasing around the bucket is 250 hours, and for the other sections is 1,000 hours, keeping the joints lubricated for a long time and extending the service life of parts by reducing abrasion and rattling.
|
●Bucket greasing interval: 250hours
●Greasing interval for other sections: 1,000hours
※The greasing interval depends on the working conditions.
|
 |
|
 A solid lubricant embedded in high strength brass forms a layer on the bushing surface to prevent contact between metals, maintaining an excellent lubricated state to reduce abrasion of joints.
 The surface of the pin is plated to increase the surface hardness and improve the wear resistance accordingly. |
| ■Steel EMS bushing |
 |
| Steel EMS is installed around the bucket |
|
|
 |
| Precautionary use of EMS |
① Grease is enclosed, however, greasing is necessary every 1000 hours or six months depending on the level of dusting conditions.
② Greasing is also necessary after any components have been submerged underwater for prolonged periods.
③ Greasing is also recommended after use with hydraulic breakers, crushers or other high impact attachments such as Rock Saws etc.
④ Bucket pins should be cleaned thoroughly when removing or fitting new attachments.

Ground Level Access to Engine Area Improves Preventative Maintenance. |
|
|
| Parts cleaning and maintenance are possible from the ground without climbing onto the upper structure of the excavator body.
|
| Remote fuel and oil filters |
|
Parallel installation of radiator and oil cooler |
| A fuel prefilter is provided as standard equipment to reduce trouble due to fuel clogging. In addition, the fuel and oil filters are installed at ground-accessible location to facilitate replacement.
|
|
A space provided at the front of the intercooler and
the tilting condenser facilitates cleaning. |
 |

 |
Ease of cleaning around radiator
The radiator and oil cooler are arranged in parallel. Furthermore, a space has been provided at the front of the intercooler and a tilting air condenser has been adopted to substantially facilitate cleaning. Dust build up can be removed easily and prevent overheating.
