Q1: What is the fuel consumption of the SH350?
A1: Fuel consumption varies by operation conditions and operator habits. In typical mining or earthwork scenarios, it averages 15–20 liters per hour, with higher usage in severe environments or heavy-duty tasks.
Q2: Is the maintenance cost high for this model?
A2: Sumitomo’s reliable components and durable design keep maintenance costs reasonable under normal use. Hydraulic oil replacement intervals extend to 5,000 hours, and lubrication points for the arm/boom require servicing every 1,000 hours, reducing routine workload and expenses. Actual costs depend on usage frequency and environment.
Q3: What harsh environments can the SH350 adapt to?
A3: It performs well in high-temperature, cold, and high-altitude conditions with proper pre-treatment and maintenance. For cold regions, use low-temperature starters, suitable fuels/lubricants, and preheating; in high-altitude areas, adjust the engine for reduced air density.
Q4: How responsive is the after-sales service for equipment failures?
A4: Sumitomo has a global after-sales network. Customers can contact local service centers or the hotline for prompt support. Response times may vary by location and logistics.
