Generator Operating Instructions

Generator Operating Instructions
I. Pre‑Startup Preparation (Critical Safety Prerequisites)
Environment Check: Place the generator in a well‑ventilated, dry, and clean area, away from flammable, explosive, or corrosive materials such as gasoline, paint, acids, and alkaline liquids. Maintain a distance of at least 1 meter from buildings and combustibles.
Strictly prohibit use in enclosed spaces (to prevent carbon monoxide poisoning). When used outdoors, take rainproof and sun‑protection measures to prevent rainwater from splashing into the generator and causing short circuits.
Equipment Check: Inspect the generator for damage, loose parts, oil leaks, or water leaks.
Check the engine oil level to ensure it is between the upper and lower marks on the dipstick and that the oil is clean and free of impurities. Add the same type of engine oil if insufficient.
Check the fuel level and add fuel of the specified grade (unleaded gasoline for gasoline generators, corresponding grade diesel for diesel generators). Smoking and open flames are strictly prohibited during refueling to avoid fuel spillage and safety hazards.
Circuit Check: Inspect the output cables for integrity, ensuring secure connections without damage, aging, or exposed wires.
Before starting, always turn off all load switches to avoid starting under load, which may damage the generator and electrical equipment.
Ensure the earthing protection device is securely connected and the earth resistance meets specifications to prevent electric shock.
Other Preparations: In cold weather, check the coolant level of water‑cooled generators and replace with antifreeze coolant if necessary.
Check the battery power to ensure sufficient starting power.
For first use or after long‑term storage, run the generator without load for 3–5 minutes. Only put it into service after confirming normal operation.
II. Operating Specifications During Operation (To Ensure Stable Performance)
Startup Procedure: Operate strictly in accordance with the generator manual.
For gasoline generators: open the fuel valve first; close the choke for cold start, then open it gradually after startup.
For diesel generators: preheat before starting. After starting, closely monitor the instrument panel to confirm normal voltage, current, speed, and other parameters (stable rated voltage, no abnormal alarms).
Load Control: After starting, run without load for 3–5 minutes until stable, then connect loads gradually.
Total load must not exceed 80% of the generator’s rated power; overloading is strictly prohibited (may cause overheating, unstable voltage, or even burnout).
Avoid frequent load switching; increase or decrease loads gradually to prevent damage from instantaneous current surges.
Operation Monitoring: During operation, regularly observe the generator’s condition:
Listen for smooth and even operation (no abnormal noise or knocking).
Check that the body temperature is normal (no excessive overheating).
Monitor oil, fuel, and coolant levels and replenish as needed (stop and cool before refueling; never add fuel while running).
If abnormal voltage, overload alarm, or overheating alarm occurs, stop immediately for troubleshooting.
Safety Prohibitions: Do not open the generator casing or touch rotating parts such as fans and belts during operation to avoid mechanical injury.
No smoking or open flames near the equipment; do not wipe running equipment with wet cloths to prevent electric shock or fire.
Keep away from the exhaust outlet, which is extremely hot and emits toxic gases including carbon monoxide to prevent burns or poisoning.
III. Post‑Shutdown Procedures (To Extend Service Life)
Shutdown Steps: Turn off the load switch and disconnect all electrical equipment first.
Allow the generator to run without load for 3–5 minutes until temperature and speed return to normal, then shut down the engine (close the fuel valve for gasoline generators, the throttle for diesel generators).
In emergencies such as equipment failure, fire, or electric leakage, press the emergency stop button directly. Inspect and resolve faults before reuse.
Cleaning and Arrangement: After the equipment has completely cooled, clean dust, oil, and debris from the surface.
Check for loose or damaged parts and tighten or replace them promptly.
Clear blockages from the exhaust and air inlets to ensure proper ventilation.
Fuel and Oil Management:
Long‑term storage (over 1 month): Drain all fuel from the tank (to prevent deterioration and clogging), drain used oil, and replace the oil filter.
Short‑term storage (within 1 month): Seal the fuel tank to prevent volatilization; start and run without load for 10–15 minutes regularly to maintain performance.
Storage: Store the generator indoors in a dry, well‑ventilated, and cool place, away from moisture, direct sunlight, and rain.
Disconnect the battery cables to prevent discharge.
Cover with a dustproof cover to protect internal components.
IV. Special Conditions and Emergency Handling
Outdoor / High‑Temperature Environment: In hot summer, improve ventilation and cooling. Avoid continuous operation for too long (recommended: cool down for 10–15 minutes after every 2–3 hours of operation).
Avoid direct sunlight; use a sunshade to prevent overheating damage.
Low‑Temperature Environment: In winter, take antifreeze measures.
Use fuel of appropriate cold‑resistance grade (‑10#, ‑20# diesel, etc.) and low‑temperature engine oil.
Preheat the engine before starting to avoid difficulty starting or damage due to low temperature.
Fault Emergency: If the engine stalls, makes abnormal noise, leaks oil, or leaks electricity during operation, stop immediately and disconnect power.
Troubleshoot common issues (insufficient oil, clogged fuel line, loose wiring, etc.).
Contact professional service if unable to resolve; do not disassemble without authorization.
In case of fire: stop immediately, cut off fuel supply, and use a dry‑powder fire extinguisher. Never use water (may spread fuel fires).
V. Routine Maintenance
Regularly inspect engine oil, fuel, coolant, battery, and other key components.
Replace engine oil, oil filter, air filter, and fuel filter at intervals specified in the manual to ensure normal operation.
Regularly inspect cables and connectors; replace damaged or aged parts promptly to ensure reliable connections.
For long‑term stored generators, start at least once a month and run without load for 15–20 minutes to check performance and recharge the battery.
Operators must be familiar with the manual in advance and follow operating procedures strictly. Prohibited operations are forbidden to avoid equipment damage and accidents.
Core Warning
Generators produce carbon monoxide during operation.
NEVER use in bedrooms, basements, enclosed garages, or any confined spaces.
Always maintain ventilation to prevent poisoning.
During operation, wear personal protective equipment including insulated gloves and non‑slip shoes to avoid electric shock or mechanical injury.
