Cummins QSB6.7 CM2250 Engine Operation and Maintenance Manual

The Cummins QSB6.7 CM2250 is the diesel engine used on Tadano machines, including cranes, where it drives the carrier and the machine's working functions. This operation and maintenance manual is the book you open when a unit comes due for its next scheduled service and you need to check the intervals. It's laid out by interval, from daily checks up to 5000 hours or 4 years, so you can find the right service quickly.

What this manual helps you do

• Plan service work against the interval sections: daily, 250 hours or 3 months, 500 hours or 6 months, and 1000 hours or 1 year.
• Follow the longer-interval procedures at 2000 hours or 2 years and 5000 hours or 4 years.
• Check the Maintenance Guidelines before you start, so the routine matches what the engine needs.
• Verify the Maintenance Specifications for the fluids and filters you're about to change.
• Prepare an engine for lay-up using the Engine Storage section.

Who this is for

A field service mechanic gets a clear interval-by-interval reference to carry to the machine. A fleet maintenance supervisor can use the same sections to set up a planned routine for each unit.
