FIRST, remember that this is the CHEAPEST large router out here, THEN ask yourself "why?"  You get what you pay for.  I had this "working like a dream" for about a year when setting up for cabinet door work it "grunted" and died.  Heck, I thought I had popped a breaker, or a "re-set," or a part that could be replaced.  WRONG, if THIS router "grunts" it fries the speed control module.  They charge about $80 for the module!  But heck, since I ALREADY have "modified" this router to use in my table, I "try" to buy the module.....  GOOD LUCK!  After 2 months of dealing with a "hitachi distributor," I finally told them to stick the order and bought a Milwaukee.  I "learned" a lesson, IF I find anything about half the price of all competitors, I probably should BUY TWO so that I can "fix" it when it breaks.  I will NEVER buy from Hitachi again, their parts "support" is useless.
