Focusing on simplified maintenance, including easy inspection, service and cleaning.

Simplified Cleaning around Engine

Parallel Arrangement of the Cooling Pack
The radiator and oil cooler are laid out in parallel arrangement for easy demounting, instead of conventional in-line arrangement. This new arrangement significantly helps facilitate cleaning around the engine.

Air-Conditioner Fresh-Air Filters
Air-conditioner fresh-air filters are relocated to the cab door side from conventional location behind the operator seat. This facilitates cleaning and replacement of freshair
filters, like air-conditioner circulation-air filters inside the cab.

Openable Air-Conditioner Condenser
The air-conditioner condenser and fuel cooler are openable for easy cleaning of them and the radiator located behind.

Increased Durability of Machine Cover
The machine cover is secured with three bolts, instead of conventional two bolts, to prevent damage due to shocks and vibration during travel over rough terrain.

Easy Draining
The engine oil pan is fitted with a drain coupler. When draining, an associated drain hose is connected to the drain coupler. The drain coupler is reliable, avoiding oil spills and vandalism.

Widened Sidewalk
The sidewalk is widened from 340 mm (Conventional model) to 510 mm for smooth walking from cab to rear. The sidewalk is the field-proven split type that permits the detaching of its rear section when travelling or operating on rough terrain.

Automatic Lubrication / Repositioned Bucket Lubricating Points
The front attachment is automatically lubricated, except for bucket lubricating points at the top of arm that are repositioned for side lubrication.

Enlarged Fuel Tank
The fuel tank is enlarged, increasing the capacity from 900 liters (Conventional model) to 1120 liters. Refueling intervals (when filled fully) extend from 16-17 hours.

Extended Hydraulic Oil Filter Change Intervals
Hydraulic oil filter change intervals are extended from 500 hours (Conventional model) to 1 000 hours to help reduce running costs.
