Craftsman Generator Manuals

Most Common Problems & Solutions (All Models)

• Generator will not start: Check fuel level; ensure choke is ON (cold start); replace spark plug; check oil level (low oil shutdown sensor).
• No power / No electricity output: Check circuit breakers; ensure output voltage selector is correct; test GFCI outlets; reset overload.
• Engine starts but runs rough: Clean or replace air filter; use fresh stabilized fuel; check spark plug gap.
• Low power / Voltage drops: Reduce load; check extension cord gauge; clean spark arrestor.
• Engine floods / Smells of gas: Wait 10–15 minutes with choke OFF; do not crank excessively.
• Oil alert / Shuts down: Check oil level immediately; use recommended 10W-30 or synthetic oil.

Inverter Generator Specific (Quiet & Portable)

• Eco Mode issues: Turn off Eco mode for high-load tools like air compressors.
• Parallel kit not working: Ensure both generators are same model and in Eco mode.
• USB ports not charging: Check 5V USB output limit (usually 2.1A total).

Dual Fuel Models

• Switching from gasoline to propane: Run gasoline dry first or close gasoline valve completely.
• Hard to start on propane: Use gasoline for first start, then switch to propane while running.

Maintenance & Safety

• Annual maintenance: Change oil, clean air filter, replace spark plug, test GFCI.
• Storage: Add fuel stabilizer or drain fuel; run dry; store in dry location.
• Carbon Monoxide Warning: Never run indoors or in enclosed areas. Use CO detectors.

Safety note: Always allow generator to cool before refueling. Never add fuel while running. Keep at least 5 feet from buildings.
