Limbing Cutting branches off a felled tree Splitting When the object you are cutting breaks off before the cut is complete There are five important factors you should consider before making a cut 1 Make sure the cutting equipment will not jam in the cut 3 Make sure the chain will not strike the ground or any other object during or after cutting 4 ls there a risk of kickback 5 Do the conditions and surrounding terrain affect how safely you can stand and move about Two factors decide whether the chain will jam or the object that you are cutting will split the first is how the object is supported before and after cutting and the second is whether it is in tension In most cases you can avoid these problems by cutting in two stages from the top and from the bottom You need to support the object so that it will not trap the chain or split during cutting IMPORTANT If the chain jams in the cut stop the engine Don t try to pull the chain saw free If you do you may be injured by the chain when the chain saw suddenly breaks free Use a lever to open up the cut and free the chain saw The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw English 25 WORKING TECHNIQUES Limbing When limbing thick branches you should use the same approach as for cutting Cut difficult branches piece by piece Cutting WARNING
7. Never attempt to cut logs while they are in a pile or when a couple of logs are lying together Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury If you have a pile of logs each log you attempt to cut should be removed from the pile placed on a saw horse or runners and cut individually Remove the cut pieces from the cutting area By leaving them in the cutting area you increase the risk for inadvertently getting a kickback as well as increasing the The log is lying on the ground There is little risk of the chain jamming or the object splitting However there is a risk that the chain will touch the ground when you finish the cut ee Bn rt a nes Cut all the way through the log from above Avoid letting the chain touch the ground as you finish the cut Maintain full throttle but be prepared for what might happen If it is possible can you turn the log stop cutting about 2 3 of the way through the log 26 English Turn the log and finish the cut from the opposite side Ss The log is supported at one end There is a high risk that it will split Start by cutting from below about 1 3 of the way through Finish by cutting from above so that the two cuts meet G The log is supported at both ends There is a high risk that the chain will jam Start by cutting from above about 1 3 of the way th
