Why won't my PowerBoss PB620LP engine start or why does it run roughly?

If your PowerBoss Blower's engine won't start or runs roughly after starting, there are several potential causes: * The battery may be dead, in which case you should recharge or replace it. * The machine might be out of fuel, requiring you to refuel. * The fuel filter could be plugged, so clean or replace the filter. * The fuel line may be broken or obstructed; blow it out with compressed air. * The tank valve might not be fully opened; open the valve slowly.
