1. Remove two guide bar nuts and remove sprocket guard. 2. Remove three muffler cover screws and remove muffler cover. 3. Remove spark arrestor screen cover, gaskets, and screen from 4. muffler body. Clean carbon deposits from muffler components.5. Replace screen if it is cracked, plugged, or has holes burned through. 6. Assemble components in reverse order. 7. NOTE: When cleaning carbon deposit, be careful not to damage the catalytic element inside muffler. Cylinder Exhaust Port IMPORTANT : The cylinder exhaust port must be inspected and cleaned of excess carbon every 3 months or 90 hours of operation in order to maintain this engine within the emissions durability period. Shindaiwa strongly recommends that you return your unit to your Shindaiwa dealer for this important maintenance service. D Exhaust Port Cleaning - Level 2 Tools required: Wood or plastic scraper, cross-head (Philips) screwdriver, 4 and 5 mm hex wrench Parts Required: (as needed) muffler gasket Remove spark plug lead from spark plug, and remove muffler 1. cover (3 screws). Place piston at top dead center. Remove muffler ( A) and muffler 2. gasket (B ). Use a wood or plastic scraping tool (C) to clean deposits from cyl3. inder exhaust port (D). Inspect muffler gasket, and replace if damaged.4. Install muffler gasket and muffler.5. Install muffler cover and attach spark plug lead.6. Replace the three muffler cover screws securely. If a torque 7. wrench is available, torque the muffler cover screws to 10 - 20 kgf- cm (1 - 2 N-m). C A B 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. D C Maintenance, continued CARBUERATOR ADJUSTMENT Engine Break-In New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required. BEFORE MAKING ADJUSTMENTS: The correct spark plug must be clean and properly gapped.1. The air filter element must be clean and properly installed.2. The muffler spark arrestor screen and exhaust port must be clear of carbon.3. The standard bar and chain combination (refer to the section, Technical Data) must be installed to the power head, 4. and properly tensioned. LOW ALTITUDE ADJUSTMENT Engines that have been adjusted to operate at high altitudes must be readjusted to operate properly at altitudes below 1100 feet. Start engine and run for several minutes to reach operating 1. temperature. Stop engine.2. Start engine and turn the high-speed needle (A) rich (CCW) until 3. the engine runs between 13,500 and 14,500 RPM. Then turn the low-speed needle (B) rich (CCW) until the engine does not hesitate when accelerated. DO NOT REMOVE LIMITER CAPS! Idle Speed Adjustment. 4. Turn “idle” speed adjustment screw (C) CW until the saw chain begins to move, then turn the screw CCW until saw chain stops moving. Turn screw CCW an additional 1/4 turn. Accelerate to full throttle for 2-3 seconds to clear excess fuel from 5. engine then return to idle. Accelerate to full throttle to check for smooth transition from idle to full throttle. If engine stops or stalls after full warm-up return the unit to your authorized Shindaiwa dealer for adjustment. C A B HIGH ALTITUDE ADJUSTMENT High altitude adjustment may be required for proper operation of this engine above 1100 feet. Start engine and run for several minutes to reach operating 1. temperature. Stop engine. 2. Start engine and turn the high speed needle (A) lean (CW) until 3. the engine runs between 13,500 and 14,500 RPM. Then turn the low speed needle lean (B) (CW) until the engine does not hesitate when accelerated. DO NOT REMOVE LIMITER CAPS! Idle Speed Adjustment. 4. Turn “idle” speed adjustment screw (C) CW until the saw chain begins to move, then turn the screw CCW until saw chain stops moving. Turn screw CCW an additional 1/4 turn. Accelerate to full throttle for 2-3 seconds to clear excess fuel from 5. engine then return to idle. Accelerate to full throttle to check for smooth transition from idle to full throttle. If engine stops or stalls after full warm-up return the unit to your authorized Shindaiwa dealer for adjustment. high low Chain and Guide Bar Combinations The following combinations may be used on 326T.
