Why does my chainsaw leak oil?

Why does my chainsaw leak oil?

In all but very exceptional cases there is nothing wrong with the chainsaw and what appears to be an oil leak is simply oil that has sprayed from the chain as it rotates at high speed, draining from the saw body and guide bar. This reduces the risk of stale fuel and oil seepage due to temperature variations.

What happens if you run a chainsaw without bar oil?

Without lubricant, the speed at which the chain moves over the chainsaw bar can cause some serious friction. A slowed-down chain and excessive fuel burning mean there’s a lot of friction between your bar and chain, which means a lot of heat is being produced that could do major damage to your saw.

How does chainsaw bar Oiler work?

Specially engineered chainsaw bar oil goes into the oil reservoir. As you throttle up, a worm drive engages the pump to send oil through a port that releases onto the bar. As the chain moves across the bar, it distributes the oil across the surface, reducing the friction and the heat that occurs when cutting.
