Maintaining optimal performance and ensuring long-term return on investment requires regular preventative maintenance. Shandong KUUGAO Machinery manufactures mini excavators using proven heavy-duty components, and continuous maintenance ensures your equipment operates smoothly under harsh construction site conditions.
1. Hydraulic System Monitoring
Daily check the hydraulic oil level, hydraulic lines, hoses, seals, and cylinder rods for signs of wear, cracks, or leaks.
2. Chassis and Track Tension Adjustment
Rubber tracks should be maintained at optimal tension to prevent derailment during rotation. Daily clean mud, gravel, and debris from the track rollers and sprockets.
3. Routine Lubrication Maintenance
Every 8-10 hours of operation, apply grease to all boom, stick, chassis, and bucket pivot points to prevent wear on pins and bushings.
