Hitachi Genuine Hydraulic Oil is specially formulated to maximize the reliability and performance of the hydraulic systems in Hitachi construction machinery. Proper hydraulic oil is critical for maintaining system efficiency, protecting components from wear, and extending the machine's operational life.
Key Features of Hitachi Hydraulic Oil
Using Hitachi Genuine Hydraulic Oil and lubricants prevents common hydraulic system failures attributed to oil contamination or degradation. Proper lubrication reduces downtime, repair costs, and enhances overall machine longevity and performance.
Real-World Impact
Operators who switch to Hitachi’s recommended oils often report smoother hydraulic operation, less frequent breakdowns, and longer service intervals, supporting both productivity and sustainability on job sites.
Conclusion
Choosing the right hydraulic oil is fundamental in heavy machinery maintenance. Hitachi’s Genuine Hydraulic Oil is engineered to deliver exceptional wear protection, operational efficiency, and environmental benefits, making it the ideal choice for maintaining robust hydraulic systems in Hitachi construction equipment. Consistent use paired with adherence to manufacturer maintenance schedules ensures machines perform at peak levels with extended component life.
Key Features of Hitachi Hydraulic Oil
- Optimized for Hitachi Machines: The oil is designed specifically for the hydraulic systems found in Hitachi equipment such as excavators and wheel loaders.
- Long Service Life: Hitachi Genuine Hydraulic Oil can extend oil change intervals up to 4,000 to 5,000 hours when not mixed with other brands, reducing operational costs.
- Wear Protection: It provides superior protection against wear and corrosion, maintaining pump and motor condition during high-pressure use.
- High Purity and Stability: The oil features a hydro-cracked base oil, which has fewer impurities and greater oxidation stability compared to conventional oils, minimizing sludge and deposits.
- Wide Temperature Range Suitability: It performs optimally over a wide temperature range, including excellent low-temperature viscosity for cold starts and resistance to thickening at high temperatures.
- Environmental Considerations: The formulation is environmentally friendly with better fuel efficiency compared to conventional oils.
- The oil is suitable for use in a variety of Hitachi machines equipped with high-pressure hydraulic systems.
- Specific intervals for oil change may vary depending on the type of attachments used; for example, breaker attachments require more frequent oil changes (~1,500 hours), while other attachments allow longer intervals (~2,000 hours).
- Use genuine Hitachi oils and follow manufacturer recommendations to maintain warranty coverage and machine integrity.
- Engine Oils: Hitachi offers specially formulated engine oils such as 15W-40 DH-1 series designed for their diesel engines, providing protection against sludge, wear, and environmental impact, even under high-speed continuous operations.
- Gear Oils: Genuine Gear Oil 80W-90 offers excellent lubricity and wear protection for travel reduction gears and swing gears in excavators.
- Greases: High-quality lithium-based greases with extreme pressure additives ensure effective lubrication of pins, bushes, and other moving parts.
