If it the oil is being pumped out at the bar mount then the bar is probably clogged and it is needing cleaning. As cutting crooked the can be problem with the way the chain is sharpen or not sharpen. Don't forget check those depth gauges too. Also depending old the bar the rails may be worn one sided.
just unbolt the blade cover adjust screw to loosen chain and remove simple as that p.s that is the side that the bar is on hope this helps if not get back to me
The blade is no longer sharp, something not unusual after about an hour of cutting. How long a blade stays sharp depends on what type of wood you're cutting, whether the blade contacted the ground or anything other than wood at any time, and how hard you are working the bar through the wood. If you are cutting hardwood or something like railroad ties the lifespan of the blade is greatly reduced. You can easily sharpen the blade with a hand file or dremel tool with a chain saw blade kit on it or have the blade sharpened. Best practice is to have one or two extra blades so you can change them as they become dull.
On the aduster screw where you tighten blade ... is there an extra nut? I think you need to screw that nut tight so the adjuster screw cannot rotate from vibration.
You remove the two nuts that hold the bar on, then the cover will come off. Don't forget to loosen the adjusting screw next to the bar to loosen it. Also, don't forget that once these two nuts are off, the bar will come off as well.
chain is too tight on the bar or is lacking lubrication oil. loosen up the bar nuts and back off the chain tensioning screw a touch. make sure the bar oil reservoir is full and the chain is receiving oil when its running.
The chain is not sharpened evenly. One side is cutting faster than the other. Also check to be sure that the bar itself is not worn excessively on one side. The cheapest way to test this is to change the chain.
