1. Clean strainer (32 KW only).
2. Switches and/or wiring loose 2. Inspect wiring for short circuits and loose connections.
or disconnected. Inspect switches for proper operation.
3. Fuel starvation. 3. Check fuel supply, fuel valves, fuel feed strainer.
4.
20 Amp circuit breaker tripping.
4.
Check for high DC amperage draw during operation.
Ensure breaker is not overly sensitive to heat which would
cause tripping.
5. Exhaust system is restricted. 5. Check for blockage or collapsed muffler.
6. Water in fuel. 6. Pump water from fuel tank(s); change filters and
bleed fuel system.
7. Air intake obstruction.
7.
Check air intake filter cartridge.
