Miscellaneous Notes on Makita 5012b electric chainsaw. NOTE: Makita 5012b electric saws don't have a metal guide plate between the bar and the the body of the saw (which is plastic). Thus it's important to keep the oiler holes in the bar clean of debris so that sufficient oil is lubricating the chain. Additionally, don't overtighten the chain as you'll increase the friction between bar and chain.and finally, do loosen the bar nut a bit prior to adjusting chain tension to keep from wearing the side of the saw prematurely. Note: Opinions vary on what type oil to use in the chain bar oiler. General consensus is to use a light weight oil. Some of the suggestions from the Carving Post are mineral oil, hydraulic oil, turbine oil, or a 10wt. winter oil. One of the more popular seems to be thinning regular bar oil with Kerosene. (1 cup kerosene to 1 gallon bar oil). Others suggest "Slick 50", "Power Punch", or a synthetic such as "AmsOil". Note: This saw does not have an anti-vibration system. For long term use, try wrapping a piece of pipe insulation (the foam type), on the upper handle and cover it with duct tape or some such). Note: This saw has a chain speed up to 3 times what many electrics run at. You need to wear all your safety gear with this (or any), saw. Don't get lulled into thinking "it's just an electric". And Remember, chaps don't have the same 'jamming' ability to stop the saw chain with an electric saw.
