      I bought the RYOBI 40VHP 12" TOPHAND CHAINSAW KIT two months ago. It has been working well until today. Although I tighten the chain correctly (to the max), it continues to get loose. What should I do?

        Answer This Question

        Hello, Scott - A traditional brushed motor has a rotor (which spins) and a stator (which is stationary). As the rotor turns, little carbon blocks called brushes physically rub against metal contacts to switch the electricity to the right places. A brushless motor does not have any rubbing brushes. Instead, electronics act like a smart traffic controller and tell the motor exactly when and where to send electricity. Brushless motors are more efficient, run cooler, provide more power, longer runtime, and longer motor life, need less maintenance, and operate more quietly.

                  Very good product, just upgraded from the 18V model. It is way better for just a couple extra bucks. It's a full ready to go kit. The battery is on the small side, you will probably need another for a bigger job., i really like it anyways.

                  Great saw for landowners!
                  A couple months back I purchased the 40V 20" Brushless RY40HPCW03 chainsaw kit for maintenance around my property. The saw is heavy - 18lb with 8AH battery and full bar oil - but well balanced, and its 3/8 low profile chain cuts well...so much torque I've never come close to the chain bogging leaning into a cut. Ryobi says this saw compares to a 52cc gas saw; cutting 11" hickory back-to-back with an 18" Echo 501P the Ryobi is a couple seconds slower per cut but the Echo comes with an Oregon 20LPX full chisel chain while the Ryobi has a 3/8lp safety chain. Installing an Oregon 91VXL070 Versacut chain improves the cut speed of this saw, and by changing the OEM sprocket out for a .325-7 sprocket, one can utilize K041 mount bars with .325 .050 gauge chains for commonality/flexibility. I did discover a standard 40V 4AH battery doesn't really work with this saw, it'll stop mid-cut like a thermal or amperage trip occurred. I suspect the 4AH EDGE battery would be fine, and standard 6AH or 8AH batteries work great. Highly impressed with this saw's capabilities and find it a great option for someone who doesn't need to run nonstop for hours on end.

                    Worked as expected! This battery-powered guy packs a punch. Took down a bunch of small trees with ease. No hesitations. Would recommend to others.

                    This 12 inch is very handy for smaller jobs, it's easy to use and I like the rear battery compartment, works well, and is light weight, not hard on the hands and wrist!!

                    Should be much better
                    [This review was collected as part of a promotion.] Chain falls off constantly, lots of power but only works for a short period before the chain issues start again. Have reset and tightened it repeatedly. Falls off about 5-10x per hour of use

                      Very happy with this chainsaw, I bought it because I had a quite large tree fall in my yard. 30” diameter stump box elder tree. It did take quite some time getting through the bigger stuff and the batteries would overheat before they would die. It was in the middle of the hottest time in the summer though. Overall a great chainsaw, but my job was probably at its max capabilities.

                        Excellent chain saw! More power than the 8v and the weight is not great, easy to manage for a woman of 74 years of age. Just cut down all the dead Areca Palms that were over 25' tall with my new machine! LOVE Ryobi equipment with battery's that last for years! Thank you Ryobi !!!

                        Chainsaw cuts!
                        Haven't done a lot of cutting. But so far, the Ryobi chainsaw performs as expected. Chain lube seems accurate, no overflowing oil, and plenty of oil to lube the bar. These are things you can see for yourself when using any chainsaw. My photo shows two 12" logs cut in half. I was told it was Blackberry tree. Whatever it is, it is hard wood. I had to cut these two logs in half because my 4-ton splitter could not handle them at this length. So, the saw works and is perfect for standard tree cutting. Not sure yet about battery life. I do want some extra batteries.

                          Second Ryobi saw for me. Battery provides good duration. Easy to maneuver. Easy to change chain. Improved well for bar/ chain oil makes for easier filling, less risk of onerflow. Satisfied!
