I tried a Google search for “Bosch ake 40-19 S chain” and found many on-line outlets. If you take your chain (they need it to use as a pattern) to a local saw shop or a good hardware they can probably fabricate one in a few minutes and you will save the shipping and handling costs.

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 :

If you are replacing a Stihl® chain, you can look at the numbers on the side of the chain to determine pitch, gauge, and other characteristics of the chain. Example: Your chain has the number 33RM2 stamped in the side of it. The last three numbers (or letters) denote characteristics of the chain.
A type Y and S chain have no significant differences other than the letters` significance in the serial number of a chainsaw manufacturer. The Y or S in the serial number of a chainsaw chain signifies some feature of the chain. The chainsaw type is really determined by the way it cuts and is identified that way.
Chainsaw chains come in three main varieties. They come in full chisel, semi chisel and low profile chains, with each being used for different tasks. The chisel refers to how the teeth are cast on the chain itself – which then determines how the chain cuts through the wood.
The length of your chain is determined by counting the number of drive links in your chain. Your drive link count has a direct correlation to your bar`s length. Be careful; a bar made by OREGON® may take a different drive link count than that of another producer.
Number of Drive Links To get the right chainsaw chain, the number of drive links on the chain must be counted if the count is not already known.
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.
72 = 3/8 pitch .050 gauge or 1.3mm. 73 = 3/8 pitch .058 gauge or 1.5mm.
Oftentimes the plates are stamped with chain size (i.e. 40, 08B, C2040, etc.). These can come in the form of numbers or letters stamped on the outside of the side plate and can help you to look up the full dimensions of your chain via manufacturer provided information.
Each Stihl chainsaw model number ends in a combination of letters, each of which stands for a specific feature for performance: B: Quick chain adjuster, a tool-less chain adjustment. C: Comfort, for ergonomic and lightweight designs.

STIHL`s green and yellow color code system serves to identify STIHL bars and chains with different kickback reduction character- istics. Green (go) marks those products which are designed to reduce the risk of kickback injury and comply with the ANSI B175. 1 kickback standard.

All Bar oils are SAE 30W non-detergent oil. Go down to the local auto parts supply and buy the cheapest SAE 30W you can find…. SAE 30W is SAE 30W regardless of what brand is on it and for bar oil it is not an issue.

I was using the saw as a chain saw last weekend to cut up an old tree stump when the chain came off. I don’t know how to access it to put it back on and don’t have a user manual. The saw belonged to my late father and I don’t know if he even kept the manual.
ANSWER : You will have to remove the cover on the side the chain bar goes into. There should be one or two nuts holding the cover on the side. The is also a chain tension adjuster you may have to loosen to put it back on. Make note of the direction of the teeth on the chain. It is an directional chain. The tension adjuster is usually a flat head screw on the front side right beside the chain bar.Unless it is a really old saw, manuals are available from most manufacturers for free download. See if you can locate a brand name and model number.
