Quick Answer
Check the generator's oil level, fuel type, and overall condition before startup after long-term storage, including spark plug condition and air filter status.
Pre-Startup Checks
Before revving up your generator after long-term storage, inspect the following critical components: oil level, fuel type, and overall condition. Check the oil level and top it off if necessary. If the generator has been stored for more than 12 months, consider draining and replacing the oil to prevent degradation. Verify the fuel type, as some fuels have a shorter shelf life than others, and mix it with a fuel stabilizer if necessary.
Spark Plug and Air Filter Inspection
Inspect the spark plug for signs of fouling or carbon buildup. Use a spark plug gap gauge to set the gap at the recommended 0.025-0.030 inches. If the plug is fouled, replace it with a new one. Next, inspect the air filter for signs of dirt, dust, or moisture. Clean or replace the air filter if necessary to ensure optimal airflow.
Electrical System Inspection
Check the electrical system, including the voltage regulator, for any signs of corrosion or damage. Clean or replace the voltage regulator if necessary. Also, inspect the wiring for any signs of wear or damage. Use a multimeter to test the voltage output of the generator and ensure it’s within the recommended range (typically 120-240V).
