[. . . ] Always follow safety precautions in the Owner's and Safety Manual. The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Careless or improper use of this product can cause serious or even fatal injury. Before operating a chain saw or other MAKITA products it is important that you read, fully understand and carefully follow the instructions outlined in this owners manual. [. . . ] Use the universal wrench delivered with the chain saw for the following work. Put the chain saw on a stable surface and carry out the following steps for mounting the guide bar and saw chain: Release the chain brake by pulling the hand guard (1) in direction of arrow. Pull the chain (6) around the sprocket nose (8) of the guide bar in the direction of the arrow. Pull the guide bar as shown by the arrow to take the slack out of the chain, so that it comes up to the bottom edge of the guide bar (10). Line up the holes in the sprocket guard (3) with the bolts (11). Turn the chain tensioningscrew (HI13) until the chain tensioning bolt (12) is aligned with the hole in the guide bar. Slightly lift the end of the guide bar and turn the chain adjusting screw (13) to the right (clockwise) until the chain rests against the bottom side of the guide bar. While still holding up the tip of the guide bar, tighten the retaining nuts (2) with the universal wrench. The tension of the chain is correct if the chain rests against the bottom side of the guide bar and can still be easily turned by hand. While doing so the chain brake must be released. Check the chain tension frequently - new chains tend to get longer during use!When checking the chain tension the engine must be switched In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 9), the chain brake will stop the chain through inertia if the kickback is sufficiently strong. the chain will stop within a fraction of a second. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergenCY- IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see "Testing chain brake")!Doing so can very quickly cause extensive engine damage!ALWAYS release the chain brake before starting the saw! Engaging the chain brake (braking) If the kickback is strong enough the sudden acceleration of the guide bar combined with the inertia of the hand guard (1)will automatically actuate the chain brake. To engage the chain brake manually, simply push the hand fotward (towards the tip of the saw) with your left hand guard (I) (arrow 1). Releasing the chain brake Pull the hand guard (2) towards you (arrow 2) until you feel it catch. Be especially careful when handling gasoline (petrol). Fuel m i x t u r e The engine of the chain saw is a high-efficiency two-stroke engine. [. . . ] Please note that in some countries particular guarantee conditions may exist.
