The lower links should not SAG, if it occurs, pull the chain. After that, pull the chain, you need, that she stretched easily. In the case of strong tension – loosen a bit the chain. It is also necessary, that would handle the inertia brake is not touching the main arm. If the inertia brake will be shifted when switching on the chainsaw, happens landing clutch.
After checking the circuit device need to refuel the chainsaw. To install it on a horizontal surface and pour oil for chain lubrication and engine, and fuel. Fuel mixture, comprised of gasoline and oil adhesion, is considered ideal. As for the grease, it is necessary to use a special, for chainsaws, because. the components of this lubricant ensures the durability of the parts and the cutting element.
Now you can start the chainsaw. Triggering occurs when the engine is cold. The first step is to put the saw on a horizontal surface, the brake is off and ignition on. The front handle must be hold by hand, be on the back right leg. To start the saw pull the starter handle. Also disconnect the inertia brake and press the gas, in order that the engine is a little warmed. And finally, check, whatever oil was supplied to the circuit, if everything is in order can get to work!

Useful tips about properly cutting the trees
The swath of trees
Do not proceed with felling trees alone – this is extremely dangerous. You must have at least one partner. To start, browse the tree for the presence of dry branches, that might fall on you. Next, inspect the area and verify, that fallen tree will not damage any standing beside the object and freely fall. Getting started, become the right of the tree, keep the chainsaw on the side (this will reduce the load on the hands and the spine). The process of felling a tree consists of podbela and principal signature. The signature is the floor angle 45 degrees to a depth of no more than a quarter of the barrel, next is the main signature. When the tree will fall, you must quickly withdraw the tool. There are many instructive videos on how, how to bring down a tree, do not be lazy to watch them before work.
If the tree felled, should be to the left of the trunk and get to the bottom branches. Cutting should toe the tires, as the top, and bottom canvases circuit. If the branch is thick and too big, divide the cutting process into several stages (you need to cut from the end of the branch to the trunk). Don't forget to consider the fact, the tree trunk can posunutie, roll, and this sometimes leads to injuries, therefore, to securely lock the tree before starting work.
Saw the trunk into several pieces
After, as all the branches trimmed, start bucking barrel. Everything is simple, important to saw the trunk into smaller sections. If the chainsaw gets stuck, in no case do not try to pull. Switch off the engine and slightly bend the barrel.
After work get rid of dust and various debris on the circuit. Next, check the chain tension and the condition of the lubricant for the engine. Also be sure to check the condition of the air filter, if necessary, clean it or change. If the chainsaw is used quite often – don't forget to change wear parts such as chain, sprocket and tire.
