GENERAL SAFETY PRECAUTIONS
Some terms that describe the bar and chain To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. [. . . ] The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. See instructions under the heading Technical data for information about sharpening your chain. See instructions under the heading Technical data for information on the size of file and gauge that are recommended for the chain fitted to your chain saw.
Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time. See instructions under the heading Lubricating the bar tip sprocket. Checking wear on cutting equipment • To prolong the life of the bar you should turn it over regularly. The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination spanner. 1 2009-02-13
ASSEMBLY
Fit the bar over the bar bolts. The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. The bar should be turned regularly for more even wear.

TECHNICAL DATA
Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvarna chain saw models 445, 445e, 450e and 450. As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius than in our list. for guide bars of the same length , all sprocket-nose guide bars of the same pitch and having the same number of sprocket teeth may be considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar may be considered to have equivalent or less kickback energy than the sprocket-nose bar. Nose radius 10T 10T 10T 10T 10T 10T 10T 10T 10T 12T Husqvarna H21/ Husqvarna H25 Husqvarna H30 Type Chain Drive link count 56 64 66 72 78 56 64 66 72 78
