The slightest contamination can result in running problems. If the throttle and choke valves, together with levers and springs were removed, they should be refitted. The spring is tensioned turns. Lubricate the shaft bearings with light oil.
Page Pressure Testing The Carburettor Repair instructions Pressure testing the carburettor Pressure testing should be carried out with the car- burettor fully assembled.
Testing should always be carried out after the carburettor has been repaired, but it can also be carried out as trouble shooting before dismantling the carburettor.

In production of Husqvarna chainsaws commenced. Husqvarna soon became one of the most respected chainsaw manufacturers in the world, with innovative design concepts. In , Husqvarna was the first chainsaw manufacturer to introduce vibration dampers to improve chainsaw ergonomics.
They have remained a world leader in field of the Husqvarna workshop manual. Following their success in making chainsaws, Husqvarna started manufacturing power cutters in And many people are familiar with the success of the Husqvarna moto service manual.
Later, other Husqvarna repair manuals were created including an array of lawn and garden tractors and utility vehicles. Illustrated diagrams are used throughout these Husqvarna service manuals. Diagnostic, test, adjustment, theory of operation, and repair information are all explored in detailed illustrations.
Another milestone in the Growth of the Husqvarna repair manual came in , with the acquisition of Diamant Boart International. Diamond cutting and an expansion of their construction machinery sector followed.
These were Gardena manual, Zenoah manual, and Klippo manual. In , Husqvarna introduced the first remote controlled demolition robot. In , Flymo was acquired by the group, followed by McCulloch in A firm grip can neutralize kickback and help you maintain Elbow control of the saw.
