On bustling construction sites, dozers are not merely construction machinery, but reliable steel partners. Hengwang Group fully recognizes that scientific and meticulous maintenance keeps equipment operating at peak performance. Below is a summary of core maintenance requirements for dozers across different operational stages:

I. Run-in Period (0–250 Hours): Precise Break-in for a Solid Foundation

Operation Guidelines: Operate gently during the first 50 hours with the load limited to 70% of the rated capacity, and avoid prolonged constant-speed running. Develop good operating habits: let the machine idle for 5 minutes after startup (extend the idling time when the temperature drops below 5°C); allow it to cool down for 5 minutes before shutdown (extend the cooling time when the temperature rises above 30°C).

Key Maintenance: Complete the first maintenance at 50 operating hours, fully replace engine oil and filters, and inspect and tighten all critical connecting parts.

Hengwang Services: Complimentary first maintenance service and exclusive maintenance file establishment to lay a solid foundation for long-term operation.

II. Peak Performance Period (250–4000 Hours): Regular Preventive Maintenance to Sustain Optimal Efficiency

Maintenance Cycle: Perform engine maintenance every 250 hours and follow the full-cycle maintenance schedule strictly.

Focus Areas: Hydraulic oil cleanliness, air filter condition, and grease replenishment at all lubrication points.

Hengwang Services: Customized maintenance packages and genuine original parts to control maintenance costs and ensure maximum operational efficiency.

III. Stable Maturity Period (4000–8000 Hours): Inspection & Component Replacement for Cost-effective Service Life Extension

Maintenance Strategy: Shift focus from routine prevention to real-time monitoring and component renewal.

Focus Areas: Wear condition of the track system, hydraulic efficiency testing, and integrity of structural components.

Hengwang Services: Professional refurbishment for engines, hydraulic systems and other assemblies, restoring over 85% of original performance at a much lower cost than purchasing new equipment.

IV. Senior Service Period (Over 8000 Hours): Specialized Care to Maximize Remaining Value

Operation Guidelines: Reduce working intensity, adopt intermittent operation mode, and shorten maintenance intervals.

Focus Areas: Renewal of electrical circuits, replacement of all sealing parts, and deep cleaning of the heat dissipation system.
