Liebherr D 944 Engine Operator Manual

The Liebherr D 944 is a diesel engine that powers cranes and other heavy machines, so everything on the machine depends on it starting, running and staying within its limits. The operator manual is what you reach for when a used machine arrives without the book in the cab, or when a relief operator needs the start-up routine and daily checks in writing. It's the document that belongs next to the machine.

What this manual helps you do

• Read the engine description before you put anyone on the machine for the first time.
• Follow the start-up and shutdown routine laid out under operating the engine.
• Check the right fuels, lubricants and coolants before each shift.
• Plan routine care using the maintenance schedule and maintenance work sections.
• Learn how to read the fault table when something goes wrong on site.

Who this is for

A crane operator or operator trainer will get the most from it. Operators use it for daily checks and safe running, and trainers use it to give new people the same written procedure every time. A buyer of a used crane can also put it on file with the machine.
