How to Use a Chainsaw – Bucking Logs – Step 6
Now that the limbs have been removed and the area around the log is cleared, you can begin bucking the log to the desired lengths. If your log is still suspended by lower branches, your job may be easier if you begin bucking from the top of the tree, as long as you are not cutting above shoulder height or have to reach. Then begin working down toward the butt. With the tree suspended off the ground, usually the sections you cut will fall effortlessly to the ground. Use the saw spikes to steady the saw while cutting. It's also a good idea to position your body away the uncut portion of the log. This will create a clear zone for you to move in the even of the log were to shift or move.
You can work like this to the point where the tree is suspended by a lower limb. At this point, you will need to cut the lower limb and let the tree settle to the ground. Be very cautious when doing this and predetermine which way the log will drop or roll when the bottom limbs are removed. You'll want to position yourself on the opposite side of the logs movement and be cautious of your bar pinching in the cut as these limbs will usually be under a considerable amount of pressure.
If you were bucking a log that is laying on the ground, there are a few things you'll need to know to perform this work properly.
First, remember that if you touch the ground with a moving chainsaw even if it's for a split second, this will be enough to dull your chain. Since the wood is laying on the ground, you will need to be cautious of this. Here you see the operator making a series of cuts in the log, not quite cutting completely through in order not to hit the ground with the chain. Once he has completed the series of cuts, he'll roll the log over 180 degrees and finish the cut. This technique is a good one to use when the log is laying flat on even ground. But often times the ground the log is lying on is not flat and requires a variety of cuts to properly buck the log.
This log is suspended with the weight focused in the middle of the log where you want to make your cut. As you cut this log, the log will begin to drop in the middle and your cut will begin to close up. If you don't immediately remove your bar from the cut, it will be pinched. To avoid this, first make a relief cut on the topside of the log. Then begin an under bucking cut from the bottom in such a manner that the cuts will intersect. When done properly, you'll be able to buck the log without pinching your guide bar but this takes a lot of practice and skill and is usually best left for a professional chainsaw operator.
This log is suspended but the weight of the tree is on the ends of the log. This means if you were to buck the log, the log will tend to move upwards when cut. If this is the case, you'll do just the opposite that you did on the previous log by making your relief cut on the bottom and the finishing cut from the top.
On either method, you can always use your plastic wedges to help keep the logs from closing in the final cuts.
