Poulan PPB350 User Manual - Page 13

The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: S Engine will not idle when the throttle is released. S The trimmer head, blade or optional attachment moves/spins at idle. Make adjustments with the unit supported so the cutting attachment is off the ground and will not make contact with any object. Hold the unit by hand while running and making adjustments. Keep all parts of your body away from the cutting attachment and muffler. Idle Speed Adjustment Allow engine to idle. Adjust speed until engine runs without trimmer head, blade or optional attachment moving or spinning (idle too fast) or stalling (idle speed too slow). S Turn idle speed screw clockwise to increase engine speed if engine stalls or dies. S Turn idle speed screw counterclockwise to decrease engine speed if trimmer head, blade or optional attachment moves or spins at idle. WARNING: Recheck the idle speed after each adjustment. The trimmer head, blade or optional attachment must not move or spin at idle speed to avoid serious injury to the operator or others. Air Filter Cover Idle Speed Screw If you require further assistance or are unsure about performing this procedure, contact an authorized service dealer or call 1--800--554--6723.

If your unit is to be stored for a period of time: S Clean the entire unit before lengthy storage. S Store in a clean dry area. S Lightly oil external metal surfaces. FUEL SYSTEM Under FUELING ENGINE in the OPERATION section of this manual, see message labeled IMPORTANT regarding the use of gasohol in your engine. Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to the gasoline in the fuel tank or fuel storage container. Follow the mix instructions found on stabilizer container. Run engine at least 5 minutes after adding stabilizer. HELPFUL TIP During storage of your gas/ oil mixture, the oil will separate from the gas. We recommend that you shake the gas can weekly to insure proper blending of the gas and oil. ENGINE S Remove spark plug and pour 1 teaspoon of 40:1, 2-cycle engine oil (air cooled) through the spark plug opening. Slowly pull the starter rope 8 to 10 times to distribute oil. S Replace spark plug with new one of recommended type and heat range. S Clean air filter. S Check entire unit for loose screws, nuts, and bolts. Replace any damaged, broken, or worn parts. S At the beginning of the next season, use only fresh fuel having the proper gasoline to oil ratio. OTHER S Do not store gasoline from one season to another.
