To manually clean, set the crane parking brake, the crane

throttle pedals released. Refer to Exhaust System Cleaning

Set up a safe area around the crane's exhaust; remove tools,
rags, grease or any debris from the engine exhaust area.
With the engine idling push the Cleaning Switch (8) to initiate
manual cleaning.
Within 5 seconds the engine should rev up to 1000 to 1400
