* MAN revamps truck production in Germany, Austria, Poland
* MAN will cut 1,400 white-collar, 400 production jobs
* Revamp "absolutely necessary" to fix MAN -VW trucks chief

BERLIN/MUNICH, June 24 (Reuters) - Germany's MAN SE said it will cut 1,800 jobs at its main trucks division part of the Volkswagen-owned company's efforts to slim down to lower costs and revive profit.
Europe's largest automaker has spent billions of euros over the past decade on expanding stakes in MAN and Swedish peer Scania to meet a long-standing goal of competing with truck market leaders Daimler and Volvo.
But VW has yet to reap significant cost savings from the combination and last month aligned MAN and Scania in a new truck holding company.
MAN said on Wednesday it would reshuffle production at major truck factories in Germany, Austria and Poland. In the past, the company has often been forced to reduce workers' hours at these plants when usage was low.
"The measures are absolutely necessary," VW trucks chief Andreas Renschler told Reuters on Wednesday at a conference in Berlin.
MAN plans to cut 1,400 white-collar jobs and another 400 jobs in production at the MAN Truck & Bus division. Reuters had reported key elements of the VW-led revamp last week.
The Munich-based company said it would avoid forced layoffs and trim the headcount through voluntary redundancy, early retirement and by not filling job vacancies.
VW, which is drawing up a new corporate structure to underpin a group-wide efficiency drive, wants to more than triple the operating margin at MAN Truck & Bus to at least 6 percent from 1.8 percent last year, a company source told Reuters.
Renschler declined to specify planned profitability targets. MAN said in March it will push cost reductions in all business areas to achieve savings of more than 600 million euros ($671.16 million) by 2017.
"We have created future-oriented prospects that will save our jobs," MAN Truck & Bus works council chief Saki Stimoniaris said of the revamp, which was agreed with labour. "There will also be comprehensive investments in all truck-making sites." ($1 = 0.8940 euros) (Reporting by Andreas Cremer and Irene Preisinger; Editing by Christoph Steitz and Jane Merriman)
