Stihl MS 150 C-E Instruction Manual - Page 9

1 Left: Right: Bottom of cap in closed position - inner mark (1) in line with outer mark. Bottom of cap in correct position for installation - inner mark is under the grip and not in line with the outer mark. N To return the cap to the open position for installation, turn the cap (with the grip up) until it drops fully into the tank opening. Next, twist the cap counterclockwise as far as it will go (approx. 1/4 turn) - this will twist the base of the cap into the correct position for installation. Then, twist the cap clockwise, closing it normally. N If your cap still does not tighten properly, it may be damaged or broken; immediately stop use of the unit and take it to your authorized STIHL dealer for repair. 001BA239 KN 001BA238 KN See also the "Fueling" chapter in your Instruction Manual for additional information. Before Starting Take off the chain guard (scabbard) and inspect the saw for proper condition and operation. (See the maintenance chart near the end of the instruction manual.) WARNING Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, stop switch and cutting attachment. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices. WARNING Check that the spark plug boot is securely mounted on the spark plug - a loose boot may cause arcing that could ignite combustible fumes and cause a fire. For proper assembly of the bar and chain follow the procedure described in the chapter "Mounting the Bar and Chain" of your instruction manual. STIHL Oilomatic chain, guide bar and sprocket must match each other in gauge and pitch. Before replacing any bar and chain, see the chapter entitled "Specifications" in the instruction manual and the sections "Kickback" and "ANSI B 175.1-2000 chain saw kickback standard" below. Since longer bars add weight and may be more difficult to control, select the shortest bar that will meet your cutting English needs. Check the throttle trigger and throttle trigger lockout for smooth action - throttle trigger must return automatically to idle position. The Master Control lever / stop switch must move easily to STOP and 0. WARNING Proper tension of the chain is extremely important. In order to avoid improper setting, the tensioning procedure must be followed as described in your manual. Always make sure the hexagonal nut(s) for the sprocket cover is (are) tightened securely after tensioning the chain in order to secure the bar. Never start the saw with the sprocket cover loose. Check chain tension once more after having tightened the nut(s) and thereafter at regular intervals (whenever the saw is shut off). If the chain becomes loose while cutting, shut off the engine and then tighten. Never try to adjust the chain while the engine is running! Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, fuel mix, grease or resin in order for you to maintain a firm grip and properly control your power tool. Starting WARNING To reduce the risk of fire and burn injuries, start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. MS 150 TC 7
