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

The radiator and oil cooler are separately laid out in a parallel for easy demounting, instead of the conventional in-line arrangement. This new parallel arrangement significantly helps facilitate cleaning around the radiator and oil cooler, and improving oil cooling capability. The air-conditioner condenser and fuel cooler can be opened to easily clean them and the radiator located behind.

In addition to a pre-filter, dual main fuel filters are provided standard to reduce clogging of the fuel line to the engine.
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 leakage and vandalism.
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 when traveling or operating on rough terrain.

The fresh air fi lter for the air conditioner is relocated to cab door side from conventional location behind the operator seat. This allows easy cleaning and replacement of the fresh air filter, like the air circulation filter inside the cab.

The front attachment is automatically lubricated (When optional auto-grease lubricator is equipped), except for bucket lubricating points at the top of arm that are repositioned for side lubrication.

The fuel tank is enlarged, increasing the capacity from 900 liters (Conventional model) to 1 120 liters. Refueling intervals (when filled fully) extend from 17 to 18 hours.

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