Idle speed is not usually set to some specific value, but is set to stop chain movement at idle, but allow the engine to keep running. Hope this helps!
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
You can find chainsaw options with a blade speed like 2000 RPM or 3000 RPM. For small tasks, 2000 RPM is sufficient. But for medium-duty tasks, we recommend to go for 3000 RPM. Some chainsaw options have their blade speed mentioned as FPM which stands for feet per minute.
If you need a heavy-duty electric chainsaw that can cut dense wood without slowing down, you`ll want to purchase an electric model that offers around 15 amps. Conversely, if you need a chainsaw for cutting small limbs, an 8- or 10-amp model should do the job.
Information we found online suggests that Stihl Pro Chainsaws have a run time of about 2,000 hours. That means the saw would last you for a minimum of 5.5 years before dying. Keep in mind this time is rated for professional chainsaws and not for regular homeowner saws.
Once the user throttles the saw, the centrifugal force overcomes the springs and the shoes move out. At a certain speed (approximately 3000 rpm) the clutch shoes engage with the inside of the sprocket and the sprocket begins to turn.
The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. A chain slides across the surface of the sawbar rail at around 5000 feet per minute. The chain is moving at 55 to 60 m.p.h. or a mile per minute ( 88 feet per second ).
Saw blade speed can be expressed in either Revolutions Per Minute (RPM) or Tooth Surface Speed (usually measured in Metres Per Second, m/s). RPM and Tip Speed have a direct relationship depending on the size (diameter) of your saw blade.
RPM refers to the revolutions per minute of the shaft. Most common motors are 1700 or 3400 approximate RPM. A direct drive, ungeared 3400RPM motor will have a 3400 RPM shaft speed.
Typically a chainsaw with a shorter bar around 14” and smaller is enough for property maintenance, trimming, pruning, and cutting down broken tree limbs. On the other hand, cutting down small trees, thick branches, and cleaning up storm damage will need a longer bar around 16”-20” to make the job easier and safer.
For home use your amp should be around 20W. For most gigs and live performances in venues that hold around 100 people, you should have either a 20W tube amp, or a 40W solid state amp if you`re playing without a band. If you`re playing with a drummer, you`ll likely need a 100W solid state amp, or a 50W valve amp.
Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised. Cutting a thick wood or timber while running at a low speed or throttle can cause the blades of the chainsaw to become dull.
Most chainsaws idle at around 2,800 to 3,200 revolutions per minute, or RPMs. At this speed, the crankshaft continues to spin, but the clutch doesn`t. When the trigger is pressed and the engine speeds up, the force pushes outward on the clutch.
Rev the car engine to about 3,000 rpm as shown on the tachometer. Let the clutch out until you feel the car move forward slightly. Now, simultaneously let out the clutch all the way while giving it more gas.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
Engine Speed at Maximum Power . (“ESMP”) means the speed at which the engine develops maximum power (rpm).
The absolute minimum in terms of power of such a chainsaw is 5 HP, although this will only be enough for light forestry work, or cutting firewood. The most efficient chainsaws intended for intensive use should have a power of around 9 HP and a 50 – 80 cm long guide bar.
Modern automobile engines are typically operated around 2000 rpm – 3000 rpm (33 Hz – 50 Hz) when cruising, with a minimum (idle) speed around 750 rpm – 900 rpm (12.5 Hz – 15 Hz), and an upper limit anywhere from 4500 rpm to 10000 rpm (75 Hz – 166 Hz) for a road car, very rarely reaching up to 12000 rpm for certain cars …
The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π).
Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it. When you have adjusted the idle—aim for 650 RPM—reconnect the idle air adjustment valve`s electrical connection. Lower the hood and turn your car off.
A good rule of thumb for RPM (when using the HF500) is to keep the setting at 15,000 rpm or higher for cutting woods. You will have more cutter speed which will make the tool cut easier and should provide a better finish.
The speed is measured in revolutions per minute (RPM). So if you need a circular saw with more power speed, then you should look for high RPMs. Usually, we suggest that you take a circular saw with anywhere between 3 000 to 5 000 + RPMs.
Blade speed refers to the rate at which a band saw blade moves around the wheels during operation, typically measured in surface feet per minute (SFPM) or meters per minute (m/min).
1. Engine size is measured in cubic centimeters (cc) or cubic inches. In general, the bigger the number, the more powerful the engine. Most homeowners will do fine with a saw in the 32 cc to 45 cc range.
Although electric chainsaws are smaller and easier to carry, most lack the power and stamina to cut down large trees. If you have big trees on your property that you want to remove or cut into firewood, a gas model is your best bet.
Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised. Cutting a thick wood or timber while running at a low speed or throttle can cause the blades of the chainsaw to become dull.

I have a new Husqvarna chain saw and when it is turn on its side it dies whats wrong.
ANSWER : Its hard to say what is causeing this, there will always be a slight difference in rpm as it moves from side to side, the fuel hose should move in the tank and follow the fuel, if the machine is idling to low it may stop as you turn it, make sure the fuel hose is not trapped in the tank.

The engine idles way too fast and will not correct with the sow speed adjustment
ANSWER : Make sure that you are adjusting the idle speed screw, not the idle jet screw (L). If you are adjusting the proper screw, then it is possible that the throttle trigger assembly in the handle has a load of sawdust/dirt that blocks proper return to idle. Take the handle apart carefully, and make notes on how the parts go back together. Check at the carburetor throttle assembly to make sure the throttle arm returns fully to the idle speed screw when the trigger is pulled and released slowly. Check the throttle spring as well to make sure it is undamaged. Hope this helps!

<!– from fixya rte –>How far to turn idle screw out after rebuild – Poulan 14 Woodshark Chainsaw
ANSWER : You’ll have to do a visual on this one. But you turn it out until the throttle plate just starts to move, where it can get a little air. This is the initial start position and you can fine tune afterwards.

How do you adjust high, low, and throttle on echo 3400 chainsaw
ANSWER : Ok, this is an easy job, and a quick tune up. First start up your saw, rev it some so it warms up. Next, make sure your saw idles, if not just turn up the idle a bit first before this. With your saw idling on the ground, turn the L screw about 1 turn either side of where it is, and listen to obtain the fastest and smoothest idle, that takes care of the L screw. Now the H screw must be adjusted while the the saw is at full throttle, turn the H screw and listen for maximum and smoothest engine speed. I sugest this be done with the chain and bar removed from the saw. After you adjust the L and H, then adjust idle to suit.
