Different directional notch methods than open face notches.
Working with chainsaws (both electric chainsaws and petrol chainsaws) during winter can be challenging. Here are some tips on what you can do to stay safe and productive when it gets cold outside.
A different work technique is used for limbing thick branches than that used for thin branches. This applies to leaf trees and other trees with thick, extensive branches. The working technique often matches the technique used for crosscutting. In order to avoid splitting and the guide bar pinching, it is important that you use the correct technique and sequence.
Crosscutting trees which have compressive stress from the bottom should be done by following this technique.
Consider the crosscutting carefully, especially for larger logs. An incorrect work technique can be dangerous and cause the trunk to split or the guide bar to become pinched. First assess the tension in the trunk. Make it a habit to look at how the trunk reacts to being cut. You may have misjudged the tension.
Crosscutting trees which have compressive stress from the top should be done by following this technique.
Stand on the left side of the trunk and begin limbing on the right side of the trunk. Work calmly and methodically, branch by branch.
Follow this working technique when limbing the underside of the tree trunck.
Follow these basic rules when using a chainsaw for more efficient use and increased personal safety.
If you have estimated the tree incorrectly or failed to follow the felling process, this may result in hang-up with another tree.
By not sawing through the full tree diameter when cutting from behind, but saving an edge on the opposite side, the tree is prevented from falling backwards allowing a felling tool to be used in the felling cut.

A bore can be used with most felling methods and can be applied regardless of guide bar length and tree size. It is essential that the bore method is carried out in the correct manner.
Safe felling requires great care and precision. The directional notch determines the direction of fall, and you fell the tree with the felling cut. Left between these two cuts is the hinge, which directs the tree down to the ground towards the planned directional target in a safe way.
For small trees, it is easiest to saw the felling cut straight from behind.
When felling larger trees you need to follow a slightly different felling technique.
The bumper spike acts as a pivot between the engine body and guide bar.
Prepare the directional notch by sawing off any root protrusions that might complicate felling. It is often useful to cut the bark on the sides of the trunk at the level of the intended directional and felling cuts so that the cuts are clear.
Before felling a tree follow these simple steps to fell safely.
A catch (a piece of unsawn wood) is saved for one last operation before the tree is felled, hence the name “Safe corner”. A major advantage of this method is that the hinge can be clearly cut and inspected before the tree is felled. The tree cannot fall backwards either due to the corner. The method is also beneficial to use on moderately forward or backward leaning trees.
Kickback can occur during most work procedures if the chainsaw is not handled carefully. This is why it is essential for you to learn and use correct saw technique. Always use a chainsaw with a working chain brake. Thumbs and fingers must be completely wrapped around the handles. Always keep your left thumb under the front handle when you use the saw to catch the saw in case of kickback.
For safe and efficient tree felling you should follow these simple steps.
Believe it or not, but “how do I start a chainsaw?” is a common question (or at least a frequent Google search) amongst chainsaw users. In this guide we’ve put together some tips on how to get your saw ready to perform.
