MOSCOW, October 5 (RIA Novosti) - Russia's largest truck maker, KamAZ, restarted its main assembly line on Monday after a freeze since September 29, the company's PR department said.

"Today, on October 5, the main KamAZ assembly line, as well as all basic and auxiliary production and management departments resumed their working process," a company statement said.

The ongoing global financial crisis has caused a slump in world demand for vehicles. The assembly line at the Volga-based truck producer was halted to clear overstock due to low sales.

"A four-day workweek was introduced for [employees] until the end of October. Some of the personnel involved in truck production will work a five-day week the last part of October," the statement said.

The company suspended production several times since the beginning of 2009, putting workers on forced holidays.

KamAZ is the world's 11th largest truck maker and the eighth largest producer of diesel engines globally. KamAZ has 96 plants in Russia, Poland, Kazakhstan, Azerbaijan, Vietnam, and Ethiopia.

In January-June 2009, KamAZ produced some 10,900 trucks. In September, some 2,800 trucks were produced by the company. Earlier company officials said KamAZ was expected to sell about 28,000 trucks in 2009, while 47,500 trucks were sold in 2008.
