The letter ‘R’ on STIHL stands for “Roteraion”. STIHL is a German company that specializes in outdoor power equipment and forestry equipment, pioneered by Andreas Stihl in 1926. STIHL uses multiple technologies in its products, one of which is Roteraion, a rotating coaxial air system used in STIHL chainsaws and trimmers.
This technology minimizes vibration and improves exhaust gas emissions, making for a more ergonomic and powerful tool. With Roteraion, the engine has two blades spinning in opposite directions, allowing for an almost balanced rotation of the engine.
This technology not only provides more power and better steam system, but also reduces the impact to the user.

The Stihl red lever is a feature that is found on Stihl gas-powered chain saws. It is basically a safety measure that prevents the saw from being started while the chain is engaged. When starting the saw, the user must first push down the Stihl red lever and then pull the starter cord.
This ensures that the chain will not move until the user is ready. Once the saw is started, the lever must remain pushed down until the user has a firm hold on the saw handle. Once the user releases the lever, the chain will once again be locked in place, preventing accidental startup.
By having the red lever, users can be reassured that the saw will not start unless it is intentionally engaged.
How can you tell a fake Stihl chainsaw?
When trying to determine if a Stihl chainsaw is fake, you should use the following guidelines:
1. Examine the Manufacturer’s Logo: Make sure that the Stihl logo is clearly visible. Genuine Stihl chainsaws have the iconic orange triangle and the “Stihl” script logo stamped on the handle.
2. Research the Serial Number: Every genuine Stihl chainsaw has a unique 18-digit serial number stamped on the housing. This serial number can be used to verify the authenticity and the production date of the chainsaw.
3. Look for Product Labels: Stihl chainsaws should have a UL label which certifies that the chainsaw meets all the necessary safety requirements, an Orange Triangle label which indicates the chainsaw is a genuine Stihl product, and a California Warning Label.
4. Inspect the Quality of the Chainsaw: If a Stihl chainsaw feels too light, has small bolts and nuts, or a mismatched paint job, then it may be a fake. Genuine Stihl chainsaws are constructed with precision and have superior components.
5. Compare Prices with Online Retailers: Any chainsaw that is significantly less expensive than other Stihl chainsaws of the same model may be counterfeit.
Ultimately, by taking these steps, you can determine whether or not a Stihl chainsaw is a genuine product. It is important to be vigilant when purchasing a Stihl chainsaw as counterfeits are often of lesser quality and are unlikely to perform to the same standards of a genuine one.
What size line does a STIHL fs90r use?
The STIHL FS90R uses a. 095″ or 2. 4mm trimmer line. The FS90R is a professional grade trimmer designed for heavier-duty use and is ideal for professional landscaping. The trimmer line can come on pre-wound spools or in bulk packages.
It is important to choose the correct size line for your trimmer; using a smaller diameter than specified can cause motor overloading and pre-mature failure. The FS90R has a maximum head speed of 10,100/min and can handle a maximum line diameter of.
095″.
How do you determine trimmer line size?
When selecting a trimmer line size, the size of your trimmer, the type of job you’re doing, and the type of line you’re using must all be taken into consideration. The size of the trimmer is important because the trimmer’s engine and cutting head demand a certain size line.
Check your product manual or contact the manufacturer if you’re unsure what size to use. The type of job you’re doing will then determine the best type of line to use. If you’re looking for a line that provides increased flexibility and is resistant to breakage, then a line such as nylon or square trimmer line should be considered.
If you’re doing more heavy-duty trimming, then one of the blades such as metal blades, blades with saw-like edges, or star-shaped line may be best. Lastly, the size of the line you’re using will be determined by the type of job you’re doing and the size of the trimmer.
For light to medium-duty trimming, using a line that is between 0. 065 inch and 0. 095 inch is usually recommended. For heavier-duty trimming, particularly with thick grass and brush, select a line size of 0.
105 inch or more. If you’re unsure, it is best to contact the manufacturer for recommended trimmer line sizes.
How do you change the string on a Stihl fs90r?
Changing the string on a Stihl fs90r is a relatively straight-forward process. First, take out the trimmer head by pressing the release button and unscrewing it from the shaft. Next, remove the spool from the trimmer head and check for any obstructions such as grass, dirt, or debris.
If any are present, discard them. After that, you can cut off a piece of string from the spool and measure it to the lengths recommended in the manual so that it is the correct length. After measuring the string, wind it around the spool in a circular pattern, with each wrap crossing over the next one.
Make sure to leave ¼ inch of extra string at the end, which will prevent the line from slipping off the spool when you reassemble the head. Once the string is wound correctly, put it back into the trimmer head and re-screw it onto the shaft.
Make sure it is secure, so that the line won’t slip off and cause an accident. With the trimmer head secured, all that is left is to give it a test and you should now be able to trim your yard with ease.
Can I use .080 trimmer line?
Yes, you can use. 080 trimmer line. This trimmer line is suitable for most string trimmers and can give great results. It is thicker than standard line but is still able to provide a good cutting edge for trimming grass and other vegetation.
It is also strong and durable so it will last longer than thinner lines, although it may not be as good for very thick weeds. When you are using. 080 trimmer line you should also take into account the size of the trimmer head to ensure that the line fits properly and safely.
You may find that. 080 line is too thick for some trimmer heads and that you need to look for a thinner line for optimal performance.
Is a Stihl fs91r 2 stroke or 4 stroke?
The Stihl FS91R is a 4-stroke trimmer. It is powered by a low-emission, fuel-efficient engine that provides increased cutting power and performance. This 4-stroke engine is more fuel-efficient and quieter than a traditional 2-stroke engine because, in addition to the fuel/air mix, it also has lubricating oil that helps to reduce friction and extend engine life.
It also meets EPA and CARB emissions standards for small off-road engines. This engine is lightweight, durable and provides excellent starting performance, as well as faster acceleration and improved throttle response.
What size trimmer string is best?
When deciding on the best size trimmer string, it is important to consider the type of trimmer you are using, the type of projects you want to tackle, and the size of the area that you are looking to trim.
Generally, string trimmers range in size from 16” up to 30”. The most popular size string trimmers are 18” and 20”, as they are great for smaller projects such as trimming around shrubs and small flower beds.
If you’re looking for a trimmer to tackle larger projects, such as those that are done around wide open lawns, then you should go for a 24” or even a 30” string trimmer. The size of the string also plays a role – if you’re looking for better precision when manicuring around small trees, then a.
095 or. 095” trimmer line is your best choice, as it will cut closer to the ground and provide a cleaner cut. For larger projects, a. 105” trimmer line is a better option as it will hold up for longer and can handle more job.
What is the fuel mix for a STIHL weedeater?
The fuel mix for a STIHL weedeater is gasoline mixed with two-stroke engine oil in a 50:1 ratio. This means that for every 50 parts of gasoline, you should add 1 part of two-stroke engine oil. It is important to use an oil specifically designed for two-stroke engines, as the oil offers extra protection for the engine components and prevents wear and tear due to friction.
STIHL oil is designed for use in all STIHL 2-stroke engines, however other quality 2-stroke engine oils labeled for air-cooled engines that meet JASO FD or ISO L-EGD standards may also be used. It is important to mix the gasoline and oil prior to fueling up the weedeater.
You should always use fresh gasoline when filling the tank of your machine, as the gasoline can degrade over time and the engine may not start or run properly. The fuel mix should be used within 30 days.
Always follow the instructions in your operator’s manual when performing this task.
Are all STIHL 2-stroke 50 1?
No, all STIHL 2-stroke engines are not identical. STIHL offers a range of 2-stroke engines with different features and characteristics, including engines of varying sizes and power outputs. Some of the most common 2-stroke engines in the STIHL range are 50.
1cc, 50. 2cc, and 51. 7cc, as well as larger models with up to 80cc of displacement. Additionally, some STIHL engines feature different carburetion systems, ignition systems and special technologies to maximize fuel efficiency and reduce emissions.
Depending on the model, a STIHL 2-stroke engine may come with manual or automatic choke, as well as air or oil-cooling systems. Some STIHL engines can be purchased as part of a complete package with the necessary accessories, such as a fuel mix bottle and a spark plug wrench, while others may require these items to be purchased separately.
Are STIHL trimmers 2-cycle or 4-cycle?
STIHL trimmers are 2-cycle engines. STIHL manufactures a wide variety of trimmers for lawn care, including curved and straight shaft trimmers, as well as brushcutters, edgers, and multitask tools. All STIHL trimmers use a 2-cycle engine, meaning that oil must be added to the gasoline to provide lubrication for the pistons and other moving parts.
STIHL does not offer any trimmers with 4-cycle engines.
Compared to 4-cycle engines, 2-cycle engines provide a more powerful engine with a lighter weight. They also require less maintenance than 4-cycle engines, as there is no need to change the oil. The downside is that they produce more emissions than 4-cycle engines and require the use of an oil-gasoline mix.
It is important to adhere to the fuel to oil mix recommended by STIHL when using a 2-cycle trimmer to ensure optimal engine performance.
