Spark plug maintenance check every 100 hours; Replace spark plugs every 300 hours or 1 year (using matching sockets), clean carbon deposits, check clearances (0.60-0.80mm), and replace damaged ones (recommended model F7RTC)
Clean the Mars extinguisher every 100 hours or 6 months, remove the muffler cover, clean the carbon deposits on the filter screen, and replace if damaged (Part # 6790); Excessive carbon deposition can lead to a decrease in power
When the battery is not used for a long time during maintenance, it should be charged for 8 hours per month using the matching charger to avoid damage caused by power loss; The battery life is about 2-3 years, replace it after damage (Part # 511019)
Fuel system maintenance: Clean the fuel tank filter every 6 months and check the fuel pipeline for any damage or leakage; Long term storage requires the addition of fuel stabilizers
2. Storage specifications
(1) Short term storage (within 1 month)
Close the fuel valve and let the engine run to automatic stop (drain carburetor fuel).
Turn off the battery switch, wipe off the dust and oil stains on the surface of the generator, place it in a dry and ventilated place, and cover it with a dust cover (breathable material).
Start the generator and run it for 10 minutes per month (with light load) to maintain engine lubrication.
(2) Long term storage (over 6 months)
Drain fuel:
Gasoline mode: Open the fuel tank drain bolt, empty the fuel tank (store it in an approved container), start the engine until it stops (empty the carburetor).
Propane mode: Close the cylinder valve, start the engine until it stops (empty the fuel pipeline).
Engine maintenance:
Replace the engine oil, remove the spark plug, inject 1 teaspoon of engine oil into the cylinder, pull the pull rope several times (to evenly distribute the engine oil), and reinstall the spark plug.
Battery handling: Disconnect the battery connector, store it separately after being fully charged, and charge it once a month.
Storage environment: Dry, ventilated, cool, away from sources of fire and heat, prohibited from mixing with flammable materials.
3. Common troubleshooting
Possible causes and solutions for fault phenomena
Unable to start 1. No oil or low oil level
2. Fuel not turned on or fuel depleted
3. Spark plugs that are damp, have carbon deposits, or have improper gaps
4. Insufficient battery voltage (electric start) 1. Add engine oil to the standard level
2. Open the fuel valve or add fuel
3. Remove the spark plug to dry/clean the carbon deposits, adjust the gap to 0.6-0.8mm, and replace if damaged
4. Charge for 8 hours with the matching charger
Stop immediately after startup. 1. CO sensor alarm (concentration exceeding standard)
2. Low oil protection triggered
3. Overload protection not reset
4. Fuel pipeline blockage 1. Move to a ventilated area, cut off power for 30 seconds, and restart
2. Add engine oil
3. Disconnect the load and press the overload reset button
4. Check the fuel pipeline and clean the filter screen
No output power 1. The output ready indicator light is not on
2. Circuit breaker tripping
3. Socket malfunction or damaged extension cord
4. Frequency conversion module failure: 1. Wait for the engine to run for 30 seconds, and then connect the load after the output stabilizes
2. Check the load and reset the circuit breaker
3. Replace the intact extension cord and check the socket wiring
4. Contact customer service for repair
Unstable operation/power decrease 1. Excessive or expired fuel impurities
2. Air filter blockage
3. Mars Extinguisher Carbon Accumulation
4. Insufficient propane pressure (propane mode) 1. Replace with fresh fuel
2. Clean or replace the air filter
3. Clean the filter screen of the Mars extinguisher
4. Replace the full bottle of propane and check that the hose is not bent
Excessive noise/severe vibration 1. ECO mode not activated (light load)
2. Uneven placement or damaged rubber foot pads
3. Excessive carbon buildup in the engine
4. Loose fan or other components 1. Activate ECO mode under light load
2. Move to a flat surface and replace the damaged foot pad
3. Clean the engine carbon deposits and replace the engine oil
4. Check and tighten loose parts
Propane mode cannot start. 1. Gas cylinder valve not open
2. Leakage at the hose interface
3. The residual gasoline in the carburetor has not been emptied
4. Low propane pressure (low temperature environment) 1. Fully open the cylinder valve
2. Check the interface with soapy water and tighten it again
3. Switch to gasoline mode and run for 5 minutes, then switch back to propane
4. Move the gas cylinder to a warm environment and start it after the pressure is restored
Safety precautions and warranty
Risk of carbon monoxide poisoning:
Only for use in outdoor ventilation areas, carbon monoxide detectors (with battery backup) need to be installed at home.
If symptoms such as dizziness, nausea, and fatigue occur, immediately move to fresh air and call the emergency number. It may be carbon monoxide poisoning.
Fire and explosion risks:
Smoking and staying away from open flames are prohibited when refueling, and contact with mufflers is prohibited when heating up (temperatures can reach 200 ° C or above).
