Chain saw demo by Adrian Finlay
On a beautiful sunny day in June Adrian gave a chain saw demonstration and talk to a group from the Chapter at Larch Hill Scout camp. He started by showing us how to start a stubborn petrol saw which had not been in use for some time. After cleaning the plug and filter with soapy water and then pouring a little neat fuel into the cylinder the saw started up without any more fuss.
Predictably there was much emphasis on safety including the use of Kevlar protective clothing. Adrian explained that if an accident did occur the Kevlar material jams the chain and effectively prevents serious injury. Gloves, overalls and boots with Kevlar are recommended for anyone doing a serious amount of chainsawing, and a full visor is also essential. He showed how to sharpen the chain which must be frequently done. With the aid of a portable vise driven into a conveniently placed log he deftly completed the task keeping up a running commentary. Useful tips included sharpening a cross cut chain at 30o and 25o for a ripsaw when using a guide of course. Also a piece of Perspex will clean the file and its best to use an oil sold specifically for the purpose. Half fill with fuel and fill to the brim with oil; that way your motor stops before the chain runs dry.
Starting the saw should be done with one knee on the ground and the right heel holding the saw firmly and with the brake applied. While cutting always avoid inserting the tip into the wood or you may get a violent kickback, very frightening and possibly lethal. To conclude the session Adrian proceeded to expertly section and cut up rounds of timber. All twelve present at this demo congratulated him on a great performance.
