EGO Power EP7500 31-Inch Extension Pole Attachment for Power Head PH1400 and Saw PSA1000

When I was looking to buy the pole saw I was also looking at the EP7500. The one question I had, which no one answered, was “can you use multiple EP7500’s together”? I can now say – YES.One reviewer said it was not recommended but I did not see any statements in the pole saw manual saying you are limited to one extension and the EP7500 has no manual.I bought two EP7500 extensions – they work together. I’m 6 feet tall. Holding the pole saw, with two extensions, over my head I was able to cut a branch around 15-20 feet above the ground. Personally, I don’t think I would have a problem using 3 or even 4 extensions but I think any more might be too much for me to handle. Remember, you have a 7 pound weight (with the bar chain oil) that is going to bounce about out on a long pole that flexes. The longer you go, the more likely the pole will not be able to handle the strain. Also, be careful walking around with this contraption. I almost smashed a window and almost hit the car forgetting I had this 12 ft long monstrosity.I found that a good way to attach the segments is push them together, if the one doesn’t push all the way in, pull it out slightly, turn it, and try again. Once it pushes in all the way, turn it back into the correct position (marked by the arrow), then pull it out slightly and push it in again until you hear the click. Then tighten the screw. At first I wall pulling it out completely and using my hand turning the drive rod a little and then trying to re-seat it – what a pain that was.My next test will be multiple extensions with the hedge trimmer attachment (Carbon Fiber since it is almost a pound lighter). Once I have tried this, I will update this review to say how that worked. I’ll also add measurements for both the pole saw and hedge trimmer.All measurements are end-to-end no battery installedPole Saw (PSA1000), Power Head(PH1400), Extension(EP7500)86.25 inched: Head Saw114.50 inches: Head Saw 1 extension142.75 inches: Head Saw 2 extensions
