388-backhoe-loader-field-test-maintenance-guide
After several weeks of international shipping and customs clearance, the customer finally received the highly anticipated 388 model — a powerful small front end loader with backhoe designed for versatile construction tasks. As soon as the machine arrived, the operator could not wait to test this reliable back hoe equipment. Without delay, they transported the machine to an open field near the construction site to conduct the first trial operation.
The test began with the loading function. As a practical a backhoe loader, the 388 machine integrates both loading and excavating capabilities in one compact structure. With a 1.0m³ front bucket capacity and 2500 kg lifting capacity, the machine easily handled piles of sand and gravel. The powerful 47KN breakout force allowed the bucket to penetrate dense material smoothly, proving that this small front end loader with backhoe is well suited for road construction, farmland projects, and small building foundations.
During the loading test, the operator also appreciated the smooth hydraulic response. The bucket lifting time of 6.8 seconds and quick dumping time of 2 seconds significantly improved work efficiency. With a dumping height of 2650 mm, trucks could be loaded easily. These features demonstrate how this versatile back hoe equipment combines power and efficiency in a compact design.
Next came the excavating test. The operator rotated the excavator arm and started digging soil in the open ground. Equipped with a 0.3m³ backhoe bucket and maximum digging depth of 4085 mm, this a backhoe loader quickly created deep trenches suitable for pipe installation and drainage work. The excavator swing angle of 180° allowed flexible digging without frequently repositioning the machine, which is a major advantage for confined job sites.
Powering the machine is the reliable YUCHAI YC4A105Z-T20 turbocharged engine, delivering 75 kW rated power at 2200 rpm and 400 N·m maximum torque. This strong engine ensures that the small front end loader with backhoe maintains stable performance even under heavy workloads. At the same time, the engine maintains good fuel efficiency with a minimum fuel consumption of 230 g/kW·h, helping contractors reduce operating costs.
Another highlight of this back hoe equipment is its durable transmission system. The fixed shaft power transmission gearbox with 2 forward and 2 reverse gears ensures smooth operation and strong traction. Combined with a YJ290 torque converter with up to 84.4% efficiency, the machine delivers stable power output while maintaining excellent maneuverability.
The steering system uses the BZZ5-250 hydraulic steering unit, providing a steering angle of 36° and a minimum turning radius of 6581 mm. This design allows the a backhoe loader to move flexibly even in narrow construction areas. With 14-17.5/19.5L-24 tires, the machine offers strong traction and stability on various terrains such as soil, gravel, and uneven ground.
After completing the field test, the customer expressed satisfaction with the machine’s performance. The small front end loader with backhoe proved to be an efficient multi-purpose machine capable of loading, digging, lifting, and transporting materials. Its versatility makes it an ideal solution for municipal engineering, road maintenance, agricultural work, and small construction projects.
388 Backhoe Loader Maintenance Guide
To ensure that this back hoe equipment maintains long-term performance and reliability, proper maintenance is essential.
1. Daily Inspection
Before starting work each day, operators should check engine oil, hydraulic oil, coolant levels, and fuel supply. Inspect hydraulic hoses and joints for leaks. Regular inspections help keep the a backhoe loader operating safely and efficiently.
2. Lubrication of Moving Parts
All pivot points, loader arms, and backhoe joints should be lubricated regularly. Proper lubrication reduces friction and wear, ensuring smooth operation of the small front end loader with backhoe during heavy-duty tasks.
3. Hydraulic System Maintenance
The hydraulic system is the core of this back hoe equipment. Operators should replace hydraulic oil and filters according to the maintenance schedule. Clean oil ensures stable pressure and improves the performance of the excavator and loader functions.
4. Engine Care
Regularly clean the air filter and check the fuel filter to maintain optimal combustion. Because the a backhoe loader often works in dusty construction environments, keeping the air intake system clean is crucial for engine longevity.
5. Tire and Brake Inspection
Check tire pressure frequently to ensure stability and safe driving. The air-over-oil caliper brake system should also be inspected periodically to maintain reliable braking performance.
