manual abstract


(Throttle lever in idling position.) NOTE Avoid pulling the rope to its dead end or returning it by releasing the knob. Such actions can cause starter failures. 5. When the engine has started, move the choke lever gradually downward to open the choke. 6. Allow the engine to warm up for a half minute before starting operation. ■ RESTARTING ENGINE WHILE ENGINE IS HOT 1. When restarting the engine immediately after stopping it, leave the choke open. 2. If the engine won't start after several attempts, close the choke and repeat pulling the rope or remove the spark plug and dry it. ■ STOPPING ENGINE Move the throttle lever to the idling position and press the stop switch (red button) until the engine comes to a complete stop. STOP SWITCH NOTE Except for an emergency, avoid stopping the engine while pulling the throttle lever. ■ ADJUSTING IDLE SPEED 1. When the engine tends to stop frequently at an idle mode, turn the adjusting screw clockwise. IDLE ADJUSTING SCREW CABLE ADJUSTER NOTE Warm up the engine before adjusting the idle speed. [10 ] Maintenance IAwarning •Make sure that the engine has stopped and is cool before performing any service to the blower. Contact with rotating blower fan or hot muffler may result in a personal injury. ■ AIR CLEANER •Check the air cleaner every 25 hours of use or more frequently if used under dusty conditions. A clogged air filter may increase fuel consumption while cutting down the engine power. Never operate the blower without the air filter or with a deformed filter element because unfiltered dusty air will quickly ruin the engine. CLEANING AIR FILTER: 1.Remove the air cleaner cover by pulling the tab on bottom and take out the filter element. 2.Use neutral detergent and warm water to clean the filter element. After cleaning, air dry the element completely. Place the filter element into the air cleaner housing and press the cover against the housing until it clicks. Never forget to attach the screen. If the screen is not attached, the cleaner will not seal properly and the dusts come into the cylinder. ■ FUEL FILTER •A clogged fuel filter may cause poor acceleration of the engine. Check periodically to see if the filter is clogged with dirt. The filter can be taken out of the fueling port using a small wire hook. Disconnect the filter assembly from the fuel pipe and unhook the retainer to disassemble it. Clean the components with gasoline. Screen ■ SPARK PLUG • The spark plug may gather carbon deposits on its firing end with reasonable use. Remove and inspect the spark plug every 25 hours and clean the electrodes as necessary with a wire brush. The spark gap should be adjusted to .025in.(0.6~0.7mm). jS|===l.025" ¿=3 T (0.6~0.7mm) CMR7A • Plug manufacturers recommend replacing the plug twice a year to avoid unexpected plug failure in a job. REPLACEMENT PLUG IS A NGK CMR7A. IMPORTANT • Note that using any spark plugs other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and damaged. • To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench. [11 ] Maintenance ■ MUFFLER ^WARNING • Inspect periodically the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, do not use the blower and have it repaired immediately. • Note that failing to do so may result in the engine catching on fire. IMPORTANT • Before starting operation, always make sure to check if the muffler is properly held by two bolts to the cylinder. (Fastening Torque: 70~110kgcm) • Even if one bolt out of three bolts is loose, the muffler may get loose during operation which may result in engine catching on fire. ■ SPARK ARRESTER •The muffler is equipped with a spark arrester to prevent red hot carbon from flying out of the exhaust outlet. Periodically inspect and clean as necessary with a wire brush. In the State of California it is required by law (Section 4442 of the California Public Resources Code) to equip a spark arrester when a gas powered tool is used in any forest covered, brush covered, or grass covered unimproved land. ■ AIR INLET SCREEN IMPORTANT • Blowing air is taken in from the air inlet screen. When air flow has dropped down during operation, stop the engine and inspect the air inlet screen for blocking by obstacles. •Note that failure to remove any such obstacles may result in the engine becoming overheated and damaged. ^WARNING • Never use the blower without the screen at the air intake of the blower. Before each use, check that the screen is attached in place and is free from any damage. [12 ] Maintenance ■ HOW TO INSTALL THE AIR INLET SCREEN TO THE VOLUTE COVER • Put the mark K of the air inlet screen to the mark p of the volute cover in line. •Turn the air inlet screen clockwise (arrow direction) and make sure it is firmly installed. • Install t...
