TRIMMERUNE For best results, replace trimmer lines when they have worn to half their odginal length. Use .155 inch diameter tdmmer line. Cut new tdmmer line length to 18-3/4 inches. After new line is installed on trimmer head, check all lines so they do not vary more then one (1) inch in length. This is important to make sure the trimmer head is balanced and will not vibrate abnormally. AWARNING: Use only the specified trimmer line. Do not use other matedals such as wire, string, rope, etc. Wire can break off during tdmming and become a dangerous missile that can cause serious injury. TO REPLACE TRIMMER LINE 1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. 2. Remove worn trimmer line from line carrier plate. 3. Fold new, cut to length, trimmer line in half and insert folded end through carder plate opening to back side of retainer clip. 4. With folded end of line at back side of retainer clip, pull line outward until line is fully seated under the retainer clip. 5. Repeat on other side of carder plate. 6. Check all lines to be sure they are the same length. 7. Reconnect spark plug wire to spark plug. Trimmer line Carrier plate opening clip ENGINE LUBRICATION Use only high quality detergent oil rated with API sen/ice classification SF-SJ. Select the oirs SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES NOTE: Although multi-viscesity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 25 hours of operation or at least once a year if the unit is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level. 10 TOCHANGE ENGINE OIL NOTE:Before tipping trimmer todrain oil,drainfueltankbyrunning engine untilfueltankisempty. 1.
