recalls continue to flow in, a pair of backpack blowers from Shindaiwa look to be claiming next. Reportedly, the "muffler's outer shell can melt, allowing exhaust gas to exit from the bottom or back side of the muffler." Consequently, the "exhaust gas may cause damage to the fuel tank creating a possible fire hazard for the user." To date, the outfit is only aware of a single incident where "a small muffler fire was involved," but no humans were maimed and no property was marred. Still, if you're the owner of an EB630 or EB630RT, we'd recommend getting set up with a free muffler replacement before firing that bad boy back up again.
