Ethanol fuel or ethyl alcohol is an alcohol additive that is commonly used in nearly all gasoline in the United States. It is derived from renewable resources such as corn, sugarcane and wheat. If you buy your gas at a gas station in the US then more than likely what you are buying contains corn-based ethanol. This gas, composed of 90% gasoline and 10% ethanol is sometimes referred to as ethane. Nearly all gasoline sold in the United States contains ethanol, even if there is not a declaration of ethanol on the pump.
What type of fuel to use.
Ethane can be used in all current Husqvarna equipment. However we recommend using at least 89- octane E-10 gasoline, which is the mid-grade between medium and premium gasoline. Fuel that is labeled E-15, E-20, E-85 and Diesel fuel are not acceptable fuels to E-10 and will cause significant damage to outdoor power equipment. Look for an indicator at the gas pump to make sure you are making the right choice. Not all states require that the ethanol level to be identified at the pomp. In these circumstances, make sure you do your own research.
Because today’s gasoline contains ethanol and alcohol, it absorbs water if exposed to air. In many cases the operator is unaware that their gasoline has become contaminated with water and unintentionally pours it into their unit. This is because your fuel mixture will separate into layers if it contains a high enough percentage of water. If you don’t shake your mixture, you may unintentionally pour a damaging concentration of water into your unit. Always vigorously shake the fuel mixture immediately before pouring.
Other ways of preventing problems related to fuel- absorption of water.
By taking the time to understand the issues surrounding today’s gasoline you are more likely to enjoy your equipment and prevent much frustration.
Things to consider when limbing.
Only move when you have the trunk between yourself and the bar of the saw. Branches on the upper side of the trunk can be cut with the saw lying on its side. You can limb the branches on the underside of the trunk at the same time as the rest if you have a good working height. If the tree has large branches, they can be under great tension, in which case you should limb them from the outside and in towards the trunk. Saw with the bar held vertically to reduce the risk of it getting caught. If the branch is very large, you might have to cut it from two sides. Observe how the branches are tensioned so that you can saw them from the correct side, otherwise there is a risk that the saw will get caught.
If the tree is lying right on the ground, you will have to wait with the branches on the bottom, until you are finished with the others and can roll the trunk over. Be careful when the trunk is close to the ground, since it’s quite a risk that you will touch something with the tip of the bar, which will cause a kickback. Now you got crosscutting left, study the tree before you start especially if the trunk is thick.
How use the chainsaw for Cross Cutting
When you finished work, it’s a good idea to take a look at your saw to make sure it’s functioning properly, it’s safe and ready to go the next time you need it. Of course, maintenance requirements depend on how much you use the saw.
Before felling any trees, find out which environmental regulations apply and make sure that you have the necessary permits. When you’ve decided to fell a tree you should think about what you can do to prevent accidents. Take note of everything that could affect safety: are there any roads, overhead lines or buildings nearby?
If so and you are a beginner, you should leave the job to someone with more experience. If you know that people often pass through the area, you should set out warning signs. Assess the tree and take notes of the various factors that could affect the felling:
Factors that can affect the felling.
Stand by the tree and decide exactly which direction you want it to fall in. Choose a feature from the surroundings as a guide. Clear obstructive undergrowth from around the tree; remove branches and other obstacles on the ground. On both sides of the tree you should be able to walk unobstructed and an angle away from the falling tree and remain there at a safe distance. The general idea of directional felling is that you first saw a directional notch, which determines which direction the tree will fall. The directional notch can be made in a variety of ways.
Felling a tree: “The opened directional notch.”
How you use the saw when felling is decided in part by the thickness of the tree.
First, let’s look at what you do when the bar is longer than the diameter of the

Best practices when using a chainsaw.
If you are not used to using a chainsaw, we recommend that you first get acquainted with the saw by practicing a while on a suitable log. There are some basic rules for using a chainsaw:
Felling larger trees.
Now let’s look at what you do with a larger tree. Just like before you create a good working environment, you might need to remove some of the branches from the bottom of the trunk.

The chainsaw is an efficient tool but it can also be dangerous if used incorrectly, that's why safety must always come first.
NOTE: Refer to your Owner's Manual for specific safety instructions on your chainsaw.
Your clothing is a very important part of this. Even if you are just cutting some firewood outside the backdoor of your house, you must use the personal protective equipment that is required in your country.
The best items of your equipment are highly visible ventilated protective jacket and trousers fitted with saw protection. Of course protective equipment cannot prevent an accident from occurring, but it can help to reduce the extent of the injury. You should also have boots with a steel toe cap, saw protection and a heavy tread, and a helmet of course with a full coverage visor and hearing protection.
Make sure you’ve got a first aid kit ready and accessible and it's a good idea to carry a mobile phone and a whistle so did you can call for help easily if something happens. Protect your hands with a pair of strong gloves and, if possible, bring someone with you when you work especially if you are inexperienced.
Have fun and stay safe when using your chainsaw. For a list of chainsaw accessories check OttawaChainSaws.com.
Filing the chain is an important part of maintaining the saw and it’s not difficult if you use the proper instructions and equipment. It’s easiest if you file the chain relatively frequently.
Filing the chain on your chainsaw.
Regular Safety Inspection and Maintenance.
When it comes to other maintenance, there are a few parts that require cleaning now and then to ensure safety and efficiency of the chainsaw .
We hope you’ve learned more about how to use a chainsaw properly. It might seem like a lot to take in, but with a little practice, you will soon become competent with the saw. Try to bring along an experienced person and the beginning and study the user’s manual.

At some point you will have to replace the bar and chain on your chainsaw. The steps are pretty much the same for all brands. Here is quick look at how it's done:
1- Make sure the saw is not HOT
2- Disengage the safety brake. (don't forget!)
3- Remove the bar cover nut(s)
4- Clean debris from cover and surrounding area
5- Put the new bar on and new chain over it with cutting teeth facing forward.
6- Install bar cover and hand tighten the nut(s)
7- Use the adjuster screw to give tension to the chain
8- Tighten the cover nut(s)
- Use the right chain by matching the: Gauge, Pitch, & number of Drive links.
- Flip bar after installing new chain
- Wear gloves and eye protection
