Engine Oil Drain Coupler |
|
|
| The engine oil pan is provided with a drain coupler. This makes it easier to do drain work and prevents oil from spattering because of the attached drain hose. |

Bucket |
|
|
| A one-piece wear plate covers the weldment area to increase the wear life of the bucket. |

New-type track guard to prevent wheel loosening |
|
|
| A new-type of track guard has been employed. This is effective in protecting the roller and preventing the shoe from coming loose.

High-Performance Return Filter |
|
|
| The hydraulic oil change interval is 5,000 hours, and the return filter change interval is 2,000 hours. 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. |

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 the interval 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 to improve the wear resistance accordingly. |
| 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 attaching new buckets.

Ground Level Access |
|
|
| Various parts of the excavator can now be cleaned and changed from ground level without climbing onto the body of the vehicle. Maintenance is no longer troublesome. |
 |
1.Double element air cleaner
2.Fuel cooler
3.Condenser
4.Battery (maintenance free)
5.Reserve tank
6.Washer tank |

●Fuel, oil filter remote
Thanks to the installation of a fuel pre-filter as standard, breakdowns caused by fuel blockages are reduced. In addition, because the fuel and oil filters are installed in positions that can be accessed from ground level, changing them is made simple. simple. |
1.Fuel pre-filter (with water separator)
2.Fuel filter (with water separator)
3.Oil filter |
