PIERCE ENTERS CHINA MARKET WITH SALE OF SIX PUMPERS TO JIANGSU PROVINCE FIRE BUREAU

OSHKOSH, Wis. Jan. 27, 2010 – Oshkosh Corporation (NYSE: OSK), announced today that its subsidiary, Pierce Manufacturing, reported its first ever sale of Pierce fire apparatus in China. A new order for six Pierce® custom pumpers was received from the Nanjing, Jiangsu Province Fire Bureau in the People’s Republic of China. The vehicles are scheduled for delivery in June 2010.

“Pierce is honored to have been selected by the Jiangsu Province Fire Bureau for this municipal fire truck order. We are proud to provide this new customer with the most technologically-advanced and best performing fire trucks in the world,” said Wilson Jones, Oshkosh Corporation executive vice president and president, Fire & Emergency. “The sale reflects Oshkosh Corporation’s dedication to increasing international sales through outstanding customer support and after sales service.”

The contract will provide Jiangsu Province with advanced fire protection along with technical services and parts. The six Pierce pumpers, built on Saber® chassis, are customized to meet the unique needs of the Jiangsu Province Fire Department and also to meet the China Compulsory Certification (CCC) standards concerning product safety. Jiangsu Province is located 300km west of Shanghai, has a population of 73 million and its gross domestic product is amongst the strongest in China. The region aspires to be the high-technology corridor of China and most of the largest global companies have a presence there. Urbanization in Jiangsu Province is second only to that in the city of Shanghai.

“Oshkosh first made inroads to China by selling our Airport Rescue & Fire Fighting equipment. We were able to build upon those relationships to introduce the region to the Pierce fire apparatus and the features that these specialized departments need,” said Desmond Soh, Oshkosh Corporation president Asian Operations. “This is a milestone for both the customer and the company, and we will continue to leverage the relationships.”

Each Pierce pumper is equipped with a 1500 gallons per minute (gpm) midship pump, Husky® 12 foam system and a 200 cfm (95 lps) compressed air foam system(CAFS) for enhanced firefighting power. Other features include a 10-inch raised roof cab for easier ingress and egress and large storage compartments with roll-up doors. In addition, the vehicles are engineered with a removable passenger side pump panel to allow easier access for maintenance.
