FAQ
Q: How do I select the right generator capacity?
A: Determine the total running load and the largest motor starting load. A capacity margin of 10–20% is generally recommended for stable operation and future expansion.
Q: What spare parts are supplied?
A: Standard spare parts typically include maintenance filters, belts, seals, and operation manuals. Additional spare parts kits can be supplied upon request.
Q: What maintenance is recommended?
A: Engine oil, coolant, filters, and fuel system should be inspected regularly according to the operating hours specified in the maintenance schedule. Routine preventive maintenance helps ensure stable performance.
Q: What is the typical production lead time?
A: Generally 20–30 days after receiving the deposit and confirming technical specifications. Delivery may vary depending on order quantity and customization requirements.
Q: Which Incoterms do you support?
A: Common terms include EXW, FOB, FCA, CFR, CIF, DAP, and other Incoterms as agreed during order confirmation.
Q: What warranty is normally provided?
A: A standard warranty of 12 months after commissioning or 1,000 operating hours (whichever comes first) is commonly available, covering manufacturing defects under normal operating conditions.
