WOOD DALE, Ill. ” Subaru introduces the new Hammer-Guard feature to its line of high performance air-cooled, 4-cycle overhead cam (OHC) EX Series engines. The Hammer-Guard is specifically engineered to protect the engine recoil from damage associated with equipment abuse during transport or on the jobsite. Engines without this type of protection are commonly dented in the recoil area, typically leading to a malfunctioning spring and unusable recoil.
Now standard on all Subaru EX Series engines, the Hammer-Guard is constructed of a high-strength poly resin composite reinforced by a thick plate of metal. By drastically increasing the engine™s durability, the new protective feature extends equipment life and eliminates the need for repairs due to accidental or negligent damage to the recoil. During field tests, the Hammer-Guard has been proven strong enough to withstand forceful blows from a small sledgehammer.
In addition to providing enhanced strength and protection, the Hammer-Guard also acts a muffler, reducing noise levels by 2 dBA. In combination with existing OHC design advantages, these features make the EX engines a full 4 dBA quieter in exhaust tone than other same-class engines.
Since arriving on the market in 2001, the Subaru EX Series has sold approximately 1.7 million units worldwide. The series includes seven models ranging in piston displacement from 126 cc to 404 cc. The engines have been rated highly by users for achieving both outstanding low-emission environmental performance and user-friendliness ” such as low noise and easy start-up operation ” while also remaining durable and reliable.
