Silky HAYAUCHI 3-Ext. Polesaw 6.3m (21')

A crew brought a cherry picker to repair a power line, but they used a Silky to cut a limb 4" in diameter, 19 feet off the ground. I wanted one.My house had two lightning strikes five years apart. It finally dawned on me that the danger came from the four pecans within 25 feet of the house. I don't know how often they are struck because pecans take it in stride. If a drooping limb touched the house, it could bring in lightning. My 11-foot pole saw wasn’t adequate to keep limbs well away from my roof and wires.Silky warns not to cut within 50 feet of electrical wires, grounded objects, or other conductors. For a 21-foot pole? Grounded conductors would include metal fences, sheds, and posts. A 50-foot distance is a good idea for lines that feed transformers on poles, but for most overhead wires, the big thing is to stop and look for any within 50 feet before extending the pole. I’d owned the saw two days when I learned that embarrassing lesson. I was showing it to a friend, who told me I’d just bumped my telephone line, four feet above me.Silky's online FAQ recommends cleaning the blade with oven cleaner and applying WD-40 before putting it away. I use 5W motor oil, primarily to keep sap from sticking. It spreads easily and protects longer than WD-40. A French's-style mustard bottle, the kind with the conical cap, makes an oil bottle that seals pretty well, is easy to spot, and resists damage. I spread it by putting my hand behind the blade and sliding it between my thumb and forefinger. I thought it was safe until I nicked my finger. Now I wear knit work gloves with polyurethane gripping surfaces. It's a lot easier to wipe oil off polyurethane than skin.The only time I found sap deposits on the blade (they were nearly invisible), was the time I’d failed to oil it. I didn’t need oven cleaner. Mild detergent worked fine.If I need to remove a tree, I can use the Silky to drop potentially lethal dead limbs. Removing limbs can also make it easier to fell the tree in the desired direction and within available space.The manufacturer doesn’t warn about binding. One day I was sawing a 2.5” limb 25 feet off the ground. It split and moved slightly when I was halfway through. For the next 5 or 10 minutes, I wondered if I’d ever get the saw loose as I walked forward and back 25 feet, over and over.A side branch had hung on another limb, causing enough twist to bind the blade. Cutting off side branches before sawing the limb could have prevented it. Cutting off side branches can also make the job safer by reducing the width the limb will sweep as it swings down. However, a limb is springier away from the trunk, and that can make sawing more difficult.I use a plumb line to sight a proposed cut from two directions at right angles. That shows me the spot of ground directly under the cut. Then I can predict where the limb will fall as it swings down toward the trunk and breaks.For a limb bigger than two inches, a marker where you’re standing can be helpful. Sawing with a pole saw can be fatiguing, especially in hot, humid weather, and fatigue could lead to an accident. If you stop for a cup of coffee, you may be unable to get the blade back in the slot unless you know exactly where you were standing.My most enjoyable cut was a piece 8 inches in diameter, 5 feet long, and 29 feet off the ground. It made quite a hole in the lawn, but because it was fairly short and had no side branches, I could be confident about how it would fall. I avoided fatigue by taking a coffee break.I had to dismantle one limb from the roof. For reliable traction, I wore shoes with unusually soft rubber soles. The Silky’s available length allowed me to stay several feet from the edge. I was glad of the sheath’s protection.A slip or miscalculation while stepping between a light, unsecured ladder and a roof, could cause a fall. I didn’t know how I could get on and off the roof safely while carrying a seven-pound pole. I discovered that I could lay the saw on the roof because the rubber handle prevents sliding.For safety, I had to cut smaller pieces than working from the ground. A sawing motion on a 6-in-12 roof requires more from the legs than the arms. Rather than find myself overheated and exhausted on the roof, I did only a little each day. It wasn’t fun, but now I don’t worry about the next lightning strike.On summer nights, it had become dangerous to walk between my front steps and the street. A tree had grown up between the steps and a street light, 75 feet away. With my Silky, I removed the limbs that were blocking the light. Now I can see all year.

I use the pole-saw about once per month. I like the design of the HAYAUCHI 390 21-ft Pole saw (Silky), choice of materials of construction, and have used it many times since purchase in 2009. Have I used it fully extended? Yes. Has it ever bent on me ... no (read the instructions and see following comments)! Have the sections quit telescoping? No! Is it falling apart? No. Do I take good care of this saw ... yes ... but that's really minimal for a casual user and appropriate dry storage? Are the materials of construction good? Yes Is the blade good? Yes, in fact I am impressed with the very good Hayauchi blade every time I use it because of the way it works. The last thing you need is a so-so blade when you're cutting a sucker branch nearly 30 feet up. Every down stroke of the Hayauchi cuts (not just kisses the branch) and then before long, down comes the sucker; always a good feeling (takes some practice, but once you've got it, it's great). I've had several brand company pole trimmers (with small branch cutters and saws), but they're not in the same league and couldn't afford to put a Hayauchi blade on the end of their poles like this one and still sell at a reasonable price. Furthermore, they don't extend as far as I need to go.For the hard work in the upper section of my trees, I hire a tree service to come in once every two to three years to trim only what needs to be trimmed, and no more. NOTE: Don't ever let a tree service get after your tree without you and them agreeing on exactly what is to be cut and what isn't (a beautiful tree can be destroyed in short time if they just simply cut away). But for sucker branches that come up in the late summer or fall (or about anytime in Houston) I know what I want to keep and I know what I want to remove. So that's where this Silky/Hayauchi works just fine.The Silky extended is 21.5 ft. My height is ~6 ft and extending the pole up with both hands firmly gripped on the Silky; I can get an additional ~2.5 ft. The result is nearly 30 feet maximum distance straight up. So with proper planning, safety glasses, good leather gloves, and being physical fit to handle such a tool, I can literally reach up from the ground and cut off small sucker branches that are no higher than ~30 feet from the ground. Warning: don't go out and try this immediately after buying this saw; unless you're in that business and understand how pole-saws respond greatly extended. In my own experience, I waited until I developed enough confidence in the use of the Silky before extending that last section and giving it maximum length. So, with use comes confidence and knowledge. Knowing you're pole-saw and how to respond when things don't go quite the way you expected will keep you out of trouble (electric lines, fences, wife's flowers, and other items nearby that the Silky could reach if it needs to be lowered quickly). You should be constantly aware of where the Silky will come down when working in any extended reaches.Like most tools of this type, there is a learning curve before you can use it safely, confidently, and successfully. Notice the oval design of the aluminum shaft sections; it is obviously strongest when held properly with the oval in the vertical, not horizontal position. When raising and lowering an extended pole, always keep the oval design of the pole in the vertical position. Practice: Extend the pole all the way out and lock it in place. Now pick it up and lift it to a position straight up and down. Not so easy, right? Extended weight at an angle (even as light as this pole/blade is) can be a real surprise and you need to know what it feels like and if you can handle it. If you can't, then simply don't go there and use only two sections because if fully extended and it comes off a branch when your pulling quickly to cut a sucker, it will gather momentum quickly on its way down and you may not be able to completely stop it before it hits the ground or whatever is there. Again, know your surroundings before using any pole saw.Pole-saws obviously aren't for everybody but this one is easy to recommend (four years experience) for occasional users like myself who appreciates the design and function of the pole and execution of an awesome blade. If you use it the way I do, it will pay for itself easily.

Die 6,3 m sind schon wirklich toll, aber leider kürzer als erhofft. Sicherlich wäre noch länger auch nicht mehr sinnvoll zu handhaben, aber am Baum ist es eben oft doch zu kurz, da fehlen dann noch 5 m :-).Ich denke 90 % aller Äste sind mit einer 3 m Variante oder Klettern/Hebebühne zu erreichen nur ein sehr kleiner Anteil liegt gerade im Fachgebiet dieser Säge.Sie ist hervorragend verarbeitet und sägt wie ein heißes Messer durch Butter (ist natürlich Quatsch, aber es ist immer wieder beeindruckend, wie gut diese Sulky Blätter sind).

長さも有るのだけど、なかなかに重たい。ただ、この重みで鋸を引く訳です^^;持ち上げたら、自重で切り落とす感じです。

Für dem Haus ein wenig zu nah gekommene Hainbuchen und Buchen stand ich vor der Wahl, einen Unternehmer mit eine sauteuren Fällung zu beauftragen oder 311 Euro beim Kauf dieser Säge zu investieren, gekauft bei dem Händler Cut360. Um so verwunderter war ich dann, dass ich nur wenige Tage nach dem Kauf diese Säge für sagenhafte 451 Euro angeboten sah, von einem anderen Händler als der, von dem ich über Amazon gekauft hatte. Da habe ich ja nochmal Schwein gehabt.Zur Säge selbst: die japanischen Sägen von Silky, ich habe noch die Pocketboy und die Zübat, sind ihr Geld wert. Für die Fällaktion, die gänzlich ohne Motorsäge vonstatten gehen sollte, konnte ich mir nichts besseres wünschen. Mit der Pocketboy hatte ich schon reichlich Erfahrungen auch im Bastelbereich machen können, obwohl sie dafür nun wirklich nicht gebaut wurde. Auch mit der Zübat macht das Sägen Freude. Erst recht mit dem weiten Einsatzfeld der Hayauchi, auch auf die volle Länge ausgezogen. Allerdings sollte man dabei aber daran denken, dass die Säge aufgrund ihres soliden Aufbaus recht schwer ist.Das macht sich schon bemerkbar, wenn man sie nur in die Hand nimmt. Die Griffumwicklung und auch die Griffform erinnern an den Griff eines Samurai-Schwertes. Allerdings ist die Handhabung eine etwas andere.Die Sägte ist nicht stufenlos in ihren Elementen verstellbar. Das ist auch gar nicht nötig bzw. es wäre eher kontraproduktiv. Die einzelnen Elemente rasten in ihren Endstufen sauber und satt ein. Die federnd gelagerten Sperrklinken in Verbindung mit dem Schnappverschluss geben doppelte Sicherheit. Das Sägeblatt ist ausreichend lang. Damit lassen sich auch dickere Äst mit einem Durchmesser von 25 - 30 cm zersägen. Auch Längsschnitte sind möglich, obwohl die Sägeblätter nur für den Schnitt quer zur Wuchsrichtung angelegt sein dürften.Kurzum: die Dinger machen richtig Spaß.Wichtig bei der Arbeit insbesondere mit der Teleskopsäge ist die Verwendung von Schutzeinrichtungen wie Arbeitshandschuhe und vor allem ein stabiler Motorsägenhelm mit Visier.

以前使っていたものより１ｍほど長くて少し不安でしたが、品物が届いて早速使ってみると、5.5ｍより高いところにしっかり届き、直径７ｃｍほどの枝が楽にザクザク切れました。最大に伸ばすとふらつき、操作にコツが要りますが、すぐに慣れました。少し筋力は必要です。今まで台に上って切っていた枝が、地面にしっかり立って切ることができて安全性も増しました。とても満足です。

とにかくよく切れる確かに重いが重さも安定して切るためには必要な要素か…！？
