I build decks for a living and have found the perfect circular saw for my needs. The saw is a powerful 15 amp saw. However, I have had to replace it three times in two years time. I build many decks around homes in the age of 25 to 30 year old range. The saw burns out and then just dies. This always happens at older homes built in the 60 and 70's. I have been able to trace it back to jobs at these homes.
I contacted Porter and they told me the following. The saw initally surges to 15 to 20 amps. Then slows down to 3 to 4 amps. But during heavy loads it may surge up to 30 or 40 amps.
This amount of draw from an older home may just not be there. The saw is starving for more juice. Porter said that garage sockets were not built for power tools of today's use.
They told me that I should have a cheap saw on hand for these jobs and not use my Porter. I could not believe what I just heard. A $175 saw could not be used where my job took me.
Other than buying my own power generator and hauling it around, does anyone else have any ideas and theories?
