3. Start engine and run several minutes to bring to operating temperature. Flash choke twice during warm-up to clear any air from the fuel system. 4. Stop engine. Turn “H” speed needle counterclockwise (CCW) to stop. Turn “L” speed needle midway between full clockwise (CW) stop and CCW stop. 5. Idle Speed Adjustment: • Start engine, turn “Idle” speed adjustment screw CW until the saw chain begins to turn, then turn screw out CCW until the saw chain stops turning. Turn screw out, CCW, an additional 1/4 turn. WARNING Cuttingattachmentmust not movewhen unitis idling. 6. Accelerate to full throttle for 2 - 3 seconds to clear any excess fuel in the engine, then return to idle. Accelerate engine to full throttle to check for smooth transition from idle to high speed. If engine hesitates turn “L” needle CCW 1/8 turn and repeat acceleration. Continue adjustment until smooth acceleration results. 7. Check idle speed and reset if necessary as described in item 5. If a tachometer is available idle speed should be set to 3200 r/min. CAUTION When starting, idling adjustment speed should be adjusted not to rotate the saw chain. Correct idle speed is adjusted 2,800 - 3,150 r/min. Or 1/4 turn CCW from the point the chain stops moving. When you experience trouble with the carburetor, contact your dealer. CS-310 26 27 CS-310 Oil filter Fuel filter Oil tank cap Fuel tank cap 0.65 mm (0.026 in.) AIR FILTER • Check before every use. • Release the cylinder cover latches, and remove the cylinder cover and air filter. • Brush off dust lightly, or clean with compressed air, or replace the air filter. • Reinstall air filter and the cylinder cover, engage latches. CHECK FUEL SYSTEM • Check before every use. • After refueling, make sure fuel does not leak from around fuel pipe, fuel grommet or fuel tank cap. • In case of fuel leakage there is a danger of fire. Stop using the machine immediately and request your dealer to inspect or replace. SPARK PLUG • Check periodically. • The standard spark gap is 0.65 mm (0.026 in.). • Correct the spark gap if it is wider or narrower than the standard gap. • Fastening torque: 150 to 170 Kgf • cm (130 to 145 in • lbf). FUEL FILTER • Check periodically. • Do not allow dust to enter fuel tank. • A clogged filter will cause difficulty in starting engine or abnormalities in engine performance. • Pull the fuel filter out through fuel inlet port with a piece of steel wire or the like. • When the filter is dirty, replace it. • When the inside of the fuel tank is dirty, rinsing the tank out with gasoline can clean it. OIL FILTER • Check periodically. • Do not allow dust to enter into oil tank. • A clogged oil filter will affect the normal lubricating system. • Pull it out through oil filling hole with a piece of steel wire or the like. • If the filter is dirty, wash it in gasoline or replace it. • When the inside of the tank gets dirty, rinsing the tank out with gasoline can clean it. Cylinder cover latch Air filter Cylinder cover Cylinder cover latch Groove Oil hole Sprocket Groove Oil hole Sprocket Worn : 0.5 mm (0.020 in.) Cylinder fins GUIDE BAR • Clean before using. -Clean the groove of the guide bar with a small screwdriver. -Clean oil holes with a wire. • Reverse guide bar periodically. • Check sprocket and the clutch and clean the bar mount area before installation of the bar. Replace either or both if worn. SPROCKET • A damaged sprocket will cause premature damage or wear of saw chain. -When the sprocket has worn out 0.5 mm (0.020 in.) or more, replace it. • Check sprocket when you install new chain. Replace it if worn. CYLINDER FINS • Check periodically. • Clogged fins will result in poor engine cooling. • Remove dirt and dust from between fins to let cooling air pass easily. Spark arrestor screen Muffler Screen cover MUFFLER SPARK ARRESTOR • Remove air cleaner cover and remove spark plug lead. • Remove spark arrestor screen cover and screen from muffler body. • Clean carbon deposits from muffler components. • Replace screen if it is cracked, or has holes burned through. • Assemble components in reverse order. NOTE Carbon deposits in muffler will cause drop in engine output. Spark arrestor screen must be checked periodically. CS-310 28 EXhAUST PORT CLEANING Level 2 Tools required: Wood or plastic scraper, Cross Head Screwdriver, 8mm Wrench Parts Required: As needed: Muffler gasket 1. Remove air filter cover and remove spark plug lead. 2. Place piston at top dead center. Remove muffler (A) and muffler gasket (B ). 3. Use a wood or plastic scraping tool to clean deposits from cylinder exhaust port. IMPORTANT Never use a metal tool to scrape carbon from the exhaust port. Do not scratch the cylinder or piston when cleaning the exhaust port. Do not allow carbon particles to enter the cylinder. 4. Inspect muffler gasket, and replace if damaged. 5. Install muffler gasket and muffler. 6. Tighten muffler mounting bolts (or nuts) to 60-80 in • lbf (70-90 kgf • cm). 7. Attach spark plug lead. 8. Replace air...
