Bruker manual HUSQVARNA CARB III

[. . . ] For inspection and maintenance see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions). Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. [. . . ] Two-stroke oil • For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two stroke-engines. Always store fuel in an approved container designed for that purpose. For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emptied. Push down the red choke control (4): As soon as the engine fires which can be heard through a "puff" sound, push down on the red choke control. As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by disengaging the throttle lock. Fit a guard to the bar before transporting the chain saw or carrying it for any distance. See instructions under the heading Technical data section to find out which lengths of bar are recommended for your saw. There are methods for felling trees with a diameter larger than the bar length. The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object. With the engine turned off, hold the chain saw over a stump or other firm object. An air filter that has been in use for a long time cannot be cleaned completely. The cooling system consists of: 1 2 3 4 5 Lubricate the bar tip sprocket each time you refuel. The bar should be turned regularly for more even wear.
