_;iLWARNING: Expedence indicates thatalcohol blended fuels (called gasohol orusing ethanol or methanol) can attractmoisture which leads to separation andformation of acids during storage. Acidicgas can damage the fuel system of anengine while in storage. To avoid engineproblems, the fuel system should beemptied before storage of 30 days orlonger. Drain the gas tank, start theengine and let it run until the fuel linesand carburetor are empty. Use fresh fuelnext season, See Storage Instructionsforadditional information. Never use engineor carburetor cleaner products in the fueltank or permanent damage may occur.A CAUTION: Fill to bottomof gas tankfillerneck. Do not overfill. Wipe offanyspilled oil or fuel.

• Set the throttle control in the fastposition, If the weeds or grass are talland thick, operate the trimmer at aslower walking speed.

• Frequentlyclean the undersideof thetdmmer to remove any grass buildup.Keep top of engine around starterdearand dean of grass clippingsand chaff,This will help engine air flow and extendengine lIfe. See =TO REMOVE ENGINECOVER" in the Maintenance section ofthis manual.

• For best results and longer lasting line,use the ends of the line to do the cutting.This is easily done by moving slowlythrough very thick and heavy weeds.

• Use the left side of tdmmer whantdmming along fences, walls, flowerbedsand other such objects.

• If trimmer lioes heeame tea short, it willtake longerto completethe job. Iftdmmer linesare wornto less than half

their original length,they should bereplaced. See "TO REPLACE TRIMMERLINE" in the Maintenance sectionof thismanual,

• Trimmer head contact withconcrete,asphalt or otherhard surfacesmaycause premature wear of the ball on .bottomof trimmer head.

TRIMMERUNEFor best results, replace trimmer lineswhen they have worn to half their odginallength. Use .155 inch diameter tdmmerline. Cut new tdmmer line length to 18-3/4inches. After new line is installed ontrimmer head, check all lines so they donot vary more then one (1) inch in length.This is important to make sure the trimmerhead is balanced and will not vibrateabnormally.AWARNING: Use only the specifiedtrimmer line. Do not use other matedalssuch as wire, string, rope, etc. Wire canbreak off during tdmming and become adangerous missile that can cause seriousinjury.

TO REPLACE TRIMMER LINE

1. Disconnect spark plug wire from sparkplug and place wire where it cannotcome in contact with spark plug.

2. Remove worn trimmer line from linecarrier plate.

3. Fold new, cut to length, trimmer line inhalf and insert folded end throughcarder plate opening to back side ofretainer clip.

Use only high quality detergent oil ratedwith API sen/ice classification SF-SJ.Select the oirs SAE viscosity gradeaccording to your expected operatingtemperature.

SAE VISCOSITY GRADES

NOTE: Although multi-viscesity oils(5W30, 10W30 etc.) improve starting incold weather, these multi-viscosity oilswill result in increased oil consumptionwhen used above 32°F. Check yourengine oil level more frequently to avoidpossible engine damage from runninglow on oil.Change the oil after every 25 hours ofoperation or at least once a year if theunit is not used for 25 hours in one year.Check the crankcase oil level beforestarting the engine and after each five (5)hours of continuous use. Tighten oil plugsecurely each time you check the oillevel.
