Blade Adjustment and Comb Orientation The care and adjustment of the blades is very important to the efficient operation of the trimmer and especially to the long life of the engine. 1. Place trimmer in vise, clamping on the frame bar. Be careful! Blades are sharp! 2. Using a 7/16” wrench, loosen all blade locknuts and unscrew the large head screws by two turns. 3. Starting with the screw nearest the gear housing, tighten the screw until the blade guard of the single edge trimmer or the protective comb of the double edge trimmer can just be moved with finger pressure and a .0015" (1 1/2 thou.) feeler blade just slips under the blade guard or comb. Tighten the locknuts while holding the screw stationary in its correct adjusted position. 4. Repeat Step 3 on the screws in turn until all are correctly adjusted. 5. Orientation of the comb is very important. The comb has staggered teeth for better cutting performance. Correct comb orientation is shown below. NOTE: Correct blade adjustment can only be achieved on clean, oiled blades. Single Edge Double Edge Comb Orientation E. Carburetor Adjustment 1. General NOTE: The diaphragm carburetor has three external adjustments. Each adjustment affects the others. The idle speed adjustment screw controls the throttle opening at idle position. The low (LO) speed adjustment screw controls the volume of fuel mixture at low engine speed. It also controls the supplementary fuel required to obtain smooth progression from idling to high speed. The high (HI) speed adjustment screw controls the volume of fuel mixture at full throttle. 2. Carburetor Adjustment Every unit is run at the factory and the carburetor is set in compliance with EPA Phase I / California Emission Regulations. In addition, the carburetor is equipped with HI and LO needle adjustment limiters that prevent settings outside acceptable limits. Limiter caps must remain or be replaced on both the Hi and Lo carburetor adjusting screws. There is no limiter cap on the idle screw. NOTE: The needle screws have a sharp point. To avoid damage to the carburetor, do not use excessive force. a. Before adjusting carburetor clean or replace air filter and muffler, "Spark Arrestor Screen". b. Make sure the cutting attachment such as hedge clipper blades are properly adjusted. e. Idle Speed Adjustment Units with Cutting Attachments. Turn "idle" spee...
