Q:Manual says tighten clutch cover nuts to 175-200 N-m (200-230 kgf-cm) . One of these values is wrong as they are not equal. I suspect the N-m is in error since 200 N-m is 147.5 ft-lbs. What is the correct value?

Answer This Question

A:  About 15 ft lbs should be ok. I just tighten it till it feels tight. I don't bring a torque wrench out into the field with me.

          Great saw for around the house
          I bought this needing a saw that could handle firewood and cleaning up trees around my woods. It does not disappoint. assembly was easy. starting it is easy. it's lightweight but rugged. I highly recommend this if you need that medium sized saw but don't want to spend $500 on the commercial version

            Amazing!
            This thing was under 2ft of flood water for a couple days thanks to Hurricane Ian & still runs like a top. Amazing product! Would buy again.

              "CARB Compliant"
              The gas tank and bar oil tank are not see-through. So in order to fill them up, you have to add a little liquid, then shine a flashlight into the tank, and repeat. The one major problem is it is very hard to start. I choked it, primed the bulb, and pulled and pulled and would not start. I took the plug out and it is completely dry. This is a California Air Resources Board (CARB) compliant engine, meaning it is set up to run extremely lean. It finally does start after about 20 pulls.

                Going on four years, still love it.
                I love this chainsaw. It's my go-to saw while my Stihl V.031 just sits around waiting. My CS-400 has the 18" bar and it's just right. We spend our summers in New Hampshire clearing our woodlot in order to build when (or if...) I retire. This saw doesn't quit. Starts right up every time. Don't run it without bar oil and flip the bar every time you change the chain and it will last forever. I can't think of anything I don't like about it and would buy another without giving it a second thought.

                  Can't change saw blade
                  The saw blade on this model is almost impossible to replace due to poor design. There is a clamp that has to go around the clutch and not enough room to spread the clamp out without modifying the body of the unit. Maybe the lawn mower repair shop has a special tool for this, at the end user should be able to change the blade without difficulty. The instruction manual doesn't even try to explain how to do it, probably because they know it's not well built and wants you to take it to somebody every time. I saw another YouTube videos that other models by Echo were not designed this way.

                    Great Chainsaw
                    This is a great quality chainsaw. I used it for the first time today and went through two tanks of gas. It worked perfectly and starts on the first pull. I would highly recommend this chainsaw.

                      Very happy
                      I have used several saws in my life. Some pretty big some small. This is a nice smaller/mid size saw. I have only ran a few tanks of fuel thru it at this time. But for what i was wanting and expecting i am very satisfied it starts very easy and has plenty of power for the size saw it is. I've cut some trees that took the entire 18 inch bar and it does a nice job. Hope it continues as is very satisfied

                      Used to cut down a black locust tree, it rocked!
                      I bought this to take down a black locust tree and it was amazing! Cut perfectly and started right away after breaking in the motor.

                        Great little saw made in the USA!
                        I own an echo cs-450p—a fantastic little saw. I use it to fell lodgepole pine for firewood. I also own an echo blower and a hedge trimmer. Both awesome tools. All are Reliable, built tuff, fairly priced, and all purchased from HD. So when i needed a small saw for use around a second home, this cs-400 was a no brainer. I needed to split some large diameter spruce bolts(16-18” in length)—too large to split with a splitting maul. So i used this to rip the bolts half thru then finished the task with the maul. This little saw never missed a tick! Until i hit a nail! Tuned up the chain and right back at it. This is a great little saw. Don’t be fooled. This thing is a beast. Fires every time. These narrow kerf saws are work horses—they cut like a hot knife thru butter. And this one is at the top of it’s class for function and economy. I will choose echo over the other brands any day for quality price ratio. Highly recommend.

                          Awesome Chainsaw
                          I bought this saw to cut firewood this year and I am very impressed with the power and performance of this chainsaw. I have cut 2 cords of wood so far with no complaints. On cold starts the saw fires right up. I prime the saw with about 6 pushes and choke pulled out. I give it a good pull and right away it wants to start. Push the choke in pull and it fires right up. I have yet to feel fatigue from holding the saw and cutting firewood. I like that the saw doesn’t vibrate excessively and it isn’t heavy either. To tighten the chain and get yourself up and running is quick and easy. I would recommend this saw quickly to those needing a saw to do the job.
