This Saw Answers Your Power Needs

Review Posted 10/19/2016
I had a very large tree I needed to take down and cut up. The base was about 50 inches in diameter and the tree was 90 feet tall. I ordered the 7910 power head and a 32", a 24" and a 20" bar and chain saws to match. This saw does everything I need it to do, quickly and reliably.
It starts every time with just one pull, amazing. The only issue I have with it is keeping the air filter clean. I use an air compressor to blow out the filter at least once a day. I wash the filter with dish washing soap every few days. This power head needs a lot of air and it is important to keep the air filter clean. If you need power, reliability and quick starting, this is the saw for you.

A True Cutting Machine

Review Posted 09/07/2016
I bought this saw in part because it could handle a 32" blade. I needed it to cut down a tree that had a 48" diameter trunk base.
Took the saw out of the box. First installed a 24" blade to see how the saw would do. Put the 32" blade on and about an hour later the tree fell exactly where I wanted it to.
This is truly a tree cutting machine.
Only deficiency is the air filter. Need to really pay attention and keep it clean if you are getting a lot of dust when you are cutting dead trees.
