As temperatures soar and construction projects accelerate, proper summer maintenance becomes critical to ensure your SECSUN excavator operates at peak performance. Discover our expert-recommended strategies to combat heat stress, humidity, and heavy workloads, safeguarding your equipment’s longevity and productivity.

    1. Cooling System Overhaul

• Summer’s extreme heat demands rigorous cooling system care:

• Radiator Deep Clean: Remove dust and debris clogging fins (reduces cooling efficiency by up to 40%).

• Fan Belt Tension: Ensure 10-15mm deflection under 10kg pressure to prevent slippage.

• Pro Tip: Install SECSUN’s optional radiator mesh guard to block airborne particulates.

    2. Hydraulic System Protection

• High temps accelerate hydraulic fluid degradation:

• Oil Analysis: Schedule monthly viscosity checks (ideal range: 46-68 cSt at 40°C).

• Hose Inspection: Look for cracks in sunlight-exposed lines – UV resistance drops 30% after 2 summers.

• Night Operation Advantage: Recommend shifting heavy digging to cooler hours to reduce system strain.

    3. Lubrication Reinvention

• Pivot Point Focus: Prioritize boom/slew ring lubrication – 78% of summer failures originate here.

• Interval Adjustment: Increase greasing frequency by 25% during sustained >35°C operations.

    4. Electrical System Defense

• Battery Care: Keep terminals corrosion-free with baking soda solution; check specific gravity weekly.

• Sensor Shielding: Protect pressure/temperature sensors with SECSUN’s reflective thermal wraps.

• Harness Check: Rodent activity peaks in summer – inspect wiring insulation for chew marks.

    5. Undercarriage Attention

• Track Tension: Heat expands metal – allow 5mm more sag than winter settings.

• Sprocket Rotation: Reverse every 500 hours to distribute wear evenly.

• Mud Management: After rainy days, pressure-wash undercarriage within 24 hours to prevent corrosion.
