瓦斯發電機啟動前的全面檢查是保障安全穩定運行的關鍵，需覆蓋燃料、電氣、機械及安全系統，排查隱患。

　　A comprehensive inspection before starting the gas generator is key to ensuring safe and stable operation, covering fuel, electrical, mechanical, and safety systems, and identifying potential hazards.

　　燃料系統需確保供應穩定純凈。檢查瓦斯管路連接，用肥皂水檢測接口是否泄漏，有氣泡需緊固或換密封件。清理過濾器內雜質和積水，避免氣缸磨損。調節瓦斯壓力至 5-15kPa，壓力不穩需調整減壓閥或檢查氣源。檢測瓦斯濃度（甲烷 30%-90%），過高或過低需調整，防止爆震或熄火。

　　The fuel system needs to ensure stable and pure supply. Check the connection of the gas pipeline, use soapy water to detect if there is any leakage at the interface, and tighten or replace the sealing components if there are bubbles. Clean up impurities and accumulated water in the filter to avoid cylinder wear. Adjust the gas pressure to 5-15kPa. If the pressure is unstable, adjust the pressure reducing valve or check the gas source. Detect gas concentration (methane 30% -90%), adjust if it is too high or too low to prevent detonation or flameout.

　　電氣系統聚焦電路與設備狀態。查蓄電池電量（電壓 12V 以上），清潔電極樁頭防氧化。緊固接線端子，確保電纜絕緣完好、接地可靠（電阻＜4Ω）。檢查控制屏儀表指示燈，測試啟動電機運轉，確保無卡滯或異響。

　　The electrical system focuses on the status of circuits and equipment. Check the battery level (voltage above 12V), clean the electrode pile head to prevent oxidation. Tighten the wiring terminals to ensure that the cable insulation is intact and the grounding is reliable (resistance<4 Ω). Check the indicator lights on the control panel and test the operation of the starter motor to ensure there is no jamming or abnormal noise.

　　機械部件檢查關乎發動機運行。潤滑油需油位達標、油質清澈，變質需更換，避免混用不同品牌。冷卻液液位達水箱 2/3 以上，查泄漏，寒冷地區需確認冰點符合要求。皮帶松緊度適中（按壓撓度 10-15mm），過松過緊均需調整。

　　Mechanical component inspection is related to engine operation. Lubricating oil should meet the oil level standard and have clear oil quality. If it deteriorates, it should be replaced to avoid mixing different brands. If the coolant level reaches more than 2/3 of the water tank, check for leaks. In cold regions, it is necessary to confirm that the freezing point meets the requirements. The tightness of the belt is moderate (with a pressing deflection of 10-15mm), and adjustments are needed for both too loose and too tight.

　　安全與輔助系統不可忽視。測試瓦斯泄漏報警裝置，確保聲光報警及電磁閥切斷功能正常。檢查排氣管通暢、消聲器完好，防排氣背壓過高或火災。通風系統需正常運行（每小時換氣 10-20 次），清理發動機周圍易燃物。

　　Safety and auxiliary systems cannot be ignored. Test the gas leak alarm device to ensure that the sound and light alarm and solenoid valve cut-off functions are normal. Check that the exhaust pipe is unobstructed, the muffler is intact, and prevent excessive exhaust back pressure or fire. The ventilation system needs to operate normally (10-20 air changes per hour) and clean flammable materials around the engine.

　　最后確認操作規范與環境。檢查轉速調節旋鈕位置，確保機房無明火、無關設備關閉。首次啟動或長期停用需手動盤車 2-3 圈，排查卡滯。操作人員戴防護裝備，站在安全位置應對突發情況。

　　Finally confirm the operating standards and environment. Check the position of the speed adjustment knob to ensure that there are no open flames in the machine room and that unrelated equipment is turned off. For the first start-up or long-term shutdown, manual turning is required for 2-3 turns to check for jamming. Operators should wear protective equipment and stand in a safe position to respond to emergencies.

　　以上檢查可降低啟動故障概率，保障設備運行與人員安全。

　　The above checks can reduce the probability of startup failures and ensure equipment operation and personnel safety.
