how would i use it on a chainsaw?

Try this. hook up a timing light to the spark plug wire (inductive type), and shine the flashing light into the tach and read it. The chainsaw will spark on every revolution, so it should read RPM directly. I've done this on antique tractors and it works nicely (checked against a mechanical tach) but on an engine with a distributor you need to double the reading because the spark plug only fires every other revolution of the crank.

Find a place to apply a piece of the reflective tape. Point the unit at the taoe, then press the button. Doesn't matter if it rotates like a shaft or a disk. The unit counts the number if reflections over a period of time. I find mine to provide very repeatable readings.

Tony, not sure what you are trying to do here. You put the tape on whatever is rotating and it will tell you the rpm. You could tape the chain or the clutch or the gear behind the clutch. You would of coarse get different rpm readings in each case. If you want engine rpm you need to be able to get the tape on the crankshaft or flywheel. Hope this helps. This is a very accurate device if you can point it at the tape during rotation

If your saw has a sprocket at the tip of the bar it should be no problem, assuming you have experience with a chain saw and know how dangerous they are if not handled properly.

Yes you can, if it doesn't fit properly it comes with brackets you can use and just about any saw will work.

the oil that is designed for lubricating the chain and bar (the thing the chain rides in/on) of a chainsaw is commonly called "bar oil" and any bar oil is fine. it has a special additive in it that makes it stick to stuff, so that it doesn't "fling off" as much as a regular oil would. however, a lot of guys who frequently use chainsaws do use things like used engine oil because it's free (bar oil is expensive!), and works nearly as well, especially on a low chain speed shortbar saw such as this. it's not as good as bar oil, but it's unlikely most people will use this saw enough to see things actually wear out on it anyhow, so in practical use there wouldn't be much difference. the oil that is designed for lubricating the chain and bar (the thing the chain rides in/on) of a chainsaw is commonly called "bar oil" and any bar oil is fine. it has a special additive in it that makes it stick to stuff, so that it doesn't "fling off" as much as a regular oil would. however, a lot of guys who frequently use chainsaws do use things like used engine oil because it's free (bar oil is expensive!), and works nearly as well, especially on a low chain speed shortbar saw such as this. it's not as good as bar oil, but it's unlikely most people will use this saw... » Read More the oil that is designed for lubricating the chain and bar (the thing the chain rides in/on) of a chainsaw is commonly called "bar oil" and any bar oil is fine. it has a special additive in it that makes it stick to stuff, so that it doesn't "fling off" as much as a regular oil would. however, a lot of guys who frequently use chainsaws do use things like used engine oil because it's free (bar oil is expensive!), and works nearly as well, especially on a low chain speed shortbar saw such as this. it's not as good as bar oil, but it's unlikely most people will use this saw enough to see things actually wear out on it anyhow, so in practical use there wouldn't be much difference. « Show Less

The black knob is a cap that covers a half inch nut that needs to be loosened, then you adjust the chain tension with the screw adjuster next to the bar that you will see if you look at the front of the saw case - right where a normal chain saw adjusts. A medium flat tipped screw driver is used to take up the slack, then tighten the half inch nut back down.. Plug in the saw and run it for a second, then unplug it and check the tension again. If the chain has loosened from where you set it, repeat. Once the slack is out of the saw chain finish tighten the half inch lock nut, and check your bar oil.I personally put the rubber cap away in a drawer so that it wouldn't get lost.

No, you have to use at lease two of the pole extensions because the battery is attached to one and the chainsaw to the other. you may use it with out the center pole.

Remove the battery from the saw. The battery should come with a charger that attaches to the battery and to a transformer that plugs into an outlet.

I don't know. Even within a chainsaw "length" size, the number of teeth can vary by one or two units, and if the chain is too short, it can be very difficult (or impossible) to install. One key number is the D72 which is probably related to the number of teeth. Good luck.

No it does not use oil like a chain saw. You need to spray the chain and bar with WD-40.

My machine works well on most woods including hardwood. This is not a 30 ton machine so if it starts to struggle i stop and re=position the wood or make a 2" slot with the chainsaw and place the splitting wedge in this slot. works nearly everytime. I think this is a great machine, portable and quiet.

The chain oiler works well on this little unit. I even use the same oil (standard bar oil) in the saw that I use on my gas saw and no problem. This Makita electric saw is well worth the money!

You could use a cut-off tool. I have a cordless Dewalt that would works well.

You can just use a bolt and a nut as spools... you put the nut on the bolt about half way then you thread the bolt into your swingarm then tighten the nut against the swingarm. less then $1 and plenty strong enough!

I have no idea. If there's a Home Depot or Lowe's near you, though, they'll have a selection of chains. They can help you, or the packages may have a profile of the chain, showing the teeth and the cogs or whatever they're called that engage the drive gear on the saw. Take the old chain with you...Chains also aren't that difficult to sharpen, and you don't need expensive tools.

Depends on the chain. Do you have any specifications? www.oregonchain.com has an excellent guide that explains all the parts of a chain. That would probably help you figure out what size chain you have. Or, if you have the Dremel kit, with the three different stones, you could figure out what size cutters your chain has by holding each bit up to a cutter to determine which one fits. Or...you could take your chain to a hardware store and compare the various round files to your chain to determine the best fit. I would guess an 18" chainsaw would require a 3/16" bit, or file, but you need to make sure before trying to sharpen it.

Get an inexpensive 30 weight oil. What you are oiling is the bar so the blade slides through it without sticking. Since the oil is thrown off, you do not want to spend a lot of money on it. They actually make a chain saw oil that is probably recycled oil but I have not been able to find any.

Not so good for that. I would have to see your saw blade to answer properly but I have my doubts. As for the 4mm chainsaw, the "round file" part is tapered too much and would distort the chain .... to my thinking. I am sure it would help out in a pinch for just one time or so but it is not designed for chain saws.

should works great on my saw, just mounts on the outside of the blade easy to install.
