Before that Semi truck merged me into the Center Median at the age of 65, I could work in the heat as long as the young whippersnappers..... I lived in the Phoenix, AZ area and worked there for 20 years....
yes, it was hot, but you learned how to deal with it, and I was able to do it good...
right up until I got whacked and that ended it.....
I found this Pole Saw at Home Depot for $139.00 for a Limited Time, I grabbed it before the ink left my laptop screen.... I love it.
I thought real hard about getting a 2nd battery . . . but, at $400 for a battery, I said no.
as it turns out, the one battery that came with it, can run in the heat a lot longer than I can, it is still showing " all green LEDs " even after I cut 3 trailer loads of limbs down.
