Depending on your saw, the reading should be between 10,000 and 14,000 rpm. That’s a wide variation, and so it’s important to look up the maximum speed of your saw before conducting this test. The engine should never run faster than the maximum speed at which it is designed to run.
“I have 12 chainsaws. I do not use an RPM tack. because I don’t consider any of them to be accurate except the ridiculously priced ones.I never hold a chainsaw wide open for more then enough time to just reach max RPM. When I find that RPM, I slightly richen the mixture-about 1/8-1/4 turn, and then check in the cut.With any two cycle engine, it is critical that you have the correct wide open adjustment that looses RPM but runs cleanly during the cut. When lifting the saw out of cut, you should witness a”fluttering-4 cycling sound. Focus on rpm under load, not while screaming with no load. The target no load RPM on that saw is 13000. Letting the saw get to operating temperature and tuning it a few hundred RPM below max WOT to allow for differences in fuel is pretty simple.
2 stroke engines are designed to run at high RPM chainsaws have a preset RPM limit from the factory to keep you from over reving them. Throttle application can change in different situations like when felling a tree when your getting close to the hinge sometimes i start pulling the chain slower.
If your chainsaw is over-revving, it indicates a lean air-fuel mixture is supplied to the engine. Loosen the screw until the chain stops revving without the trigger pressed with the engine on. If you ask an expert, the number one factor behind the chainsaw surge is the engine running lean.
how high do chainsaws rev Related Question:
Should you run a chainsaw at full throttle?
Engine Protection 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.
Can you over rev a chainsaw?
A chainsaw optimal cutting speed can ease up the cutting performance and save time. But as they say, “excess is bad,” an over-revving chainsaw can be dangerous to operate and is likely to cause an engine seizure.
How many RPM is a gas chainsaw?
Pull the throttle trigger, run the chain saw at full speed and note the tachometer reading. Depending on your saw, the reading should be between 10,000 and 14,000 rpm.
Why does my chainsaw rev too high?
The throttle valve (butterfly) simply cuts off the supply of combustible air/fuel and the engine stops. If this adjustment is set too high, the high idle speed will cause the centrifugal clutch to engage and the chain will run. This is a dangerous condition and should never be allowed.
Do you need to break in a chainsaw?
Typically we recommend a break in period of 6-10 tanks of fuel. During this period the engine should not be allowed to run at high RPMs for extended periods of time.
Can you rev chainsaw with brake on?
Running a chainsaw with the brake on can be dangerous for you and anyone in your vicinity. The chainsaw will not cut, but it still creates sparks that can cause fires or startle nearby pets. It also doesn’t allow the saw to cool down enough which increases the likelihood of overheating and breaking down.
Should you let a chainsaw warm up?
The gas engine in a gas chainsaw should warm up, but due to the engine’s small size, this will happen quickly. Normally the engine will run for a short time after startup before you really start using it, giving the oil enough time to warm up and lubricate all engine parts.
How long should you let a chainsaw warm up?
if its below zero, I definately let all motors warm up. above 60 deg out i let them run for 30 sec to a minute.
How fast is a chainsaw?
Cutting speed of an Average Chainsaw The piston speed of an average chainsaw is 2500 square feet per minute. The average chain sliding speed across the bar is 5000 square feet per minute. It means your chain will run at 55 to 60 miles per hour or 1 mile per minute, which is equivalent to 88 square feet per second.
How do you use a chainsaw tach?
Record the engine speed with the tachometer. Look up your chain saw’s maximum safe speed in the operator’s manual. If the tachometer reads more than that speed, turn the “H” screw counterclockwise until the speed falls below the maximum safe speed value.
Why does my chainsaw cut out when revved?
If the filter becomes clogged, not enough fuel will reach the engine for it to run properly. Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle.
What is the most common chainsaw injury?
The most common hazards associated with chainsaws are injuries caused by kickback, pushback, and pull-in. Kickback is the most common and poses the greatest hazard. Kickback occurs when the rotating chain is stopped suddenly by contact with a more solid area throwing the saw rapidly backward toward the operator.
Can you cut wet wood with a chainsaw?
Can you cut wet wood with a chainsaw? Yes, you can cut the wet wood with a chainsaw. Besides, there is a misconception that wet wood can impact the chainsaw bar and chain. But actually, the damp wood will not dull the chainsaw any faster than using it on other types of wood.
How long do Husqvarna chainsaws last?
It ultimately comes down to the factors listed above (especially maintenance). That being said, you can expect a quality chainsaw to last you at least 10 years or more. But if you take care of it, I know people who have saws that have lasted 20-30 years and even longer.
Does ice dull a chainsaw?
Yes, you can cut ice with your chainsaw. You don’t have to apply any mineral oil to prevent the water from pollution. To prevent the blade from rusting, you will have to look after your chainsaw.
