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.
Why does my chainsaw run full throttle?
If your chainsaw engine dies at full throttle, check the following parts: the carburetor, fuel lines, fuel filter, air filter, and muffler.
How long should you run a chainsaw?
Depending on the type and usage, you can expect a gas Chainsaw to run between 15 and 40 min before you have to fill it up again. Most battery-powered chainsaws have a run time of up to 2 hours, but there are high-capacity power packs that will last much longer.
Should a chainsaw spin at idle?
The idle screw usually is near or behind the air filter. Adjust the screw to restrict fuel delivery by turning it clockwise with a screwdriver until the chain stops turning. The saw must be running when you do this.
Is it okay to start a chainsaw without the bar on?
I do not recommend letting it run for more than 5 minutes. Without a chain, the chainsaw will cause the engine to rev higher. This can eventually overheat the engine’s components and increase wear and tear.Revving the engine without a chain will also put more load on the centrifugal clutch.
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.
Why does my Stihl chainsaw dies when I give it gas?
An engine stalls when it’s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it’s idling, adjusting the idle screw, which usually is marked LA, should help.
Why does my Poulan chainsaw dies when I give it gas?
A clogged fuel filter is often caused by leaving old fuel in the chainsaw. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and cause the engine to stall.
Why does my chainsaw start but wont stay running?
A clogged fuel filter will starve your chainsaw’s engine, and it can also damage it by letting contaminated fuel into the engine. Bad fuel can also clog the carburettor. Clogged carburettors are one of the most common reasons why a chainsaw won’t stay running or start at all.
How often should you sharpen chainsaw?
A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn’t get too dull. On average, a chainsaw blade will retain its sharpness for about 3 hours of actively cutting through wood.
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.
How do I get my chainsaw to idle?
1 – When the saw is warm and not running, turn the adjusting screw in (clockwise) a half turn, start the saw, repeat this process until the saw idles. 2 – The saw now idles, great! But it should idle without the chain moving.
How fast does a chainsaw chain move?
Engaging the Clutch
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.
Can I use a chainsaw to cut through ice?
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.
What happens if you run a chainsaw without bar and chain oil?
No bar oil equals increased friction and heat. That adds up to a huge increase in chain and bar wear. Without bar oil, the chain teeth, drivers and links will all wear far more quickly. The increased friction can cause teeth to break.
Can you put a smaller blade on a chainsaw?
Yes, but you need a bar designed to fit on your saw. There are different designs for different saws, and the bar has to match the chain/sprocket configuration as well.
Can a chainsaw be used in the rain?
Yes, you can. The pouring rain will not damage your chainsaw, and you can perfectly continue working on your project. Just make sure the engine is not submerged in water. So, if you were thinking about postponing your woodcutting plans due to rain or snow, now you know there is no harm.
How do you break in a chainsaw after rebuild?
in chainsaws that recommend 8 oz to 1 ga. On a fresh rebuild, I use 40-1 and add about 1/2 teaspoon of extra oil to full tank. I use the saw, with extra oil, but avoid high rpm out of cut and extended idling, until two or three tanks have been used. After that, I use regular mix,40-1 and do final carb setting.
What should you not cut with a chainsaw?
Don’t Cut With a Dull Blade
Cutting with a sharp blade actually extends the life of your chain saw. That’s because a sharp blade pulls itself into the wood, while a dull blade requires lots of downward pressure. That pressure wears out the bar, drive links, clutch sprocket and clutch.
Why does my chainsaw only run on choke?
If your chainsaw only runs with the choke on, it is likely an issue with your carburetor.
