To increase the oil flow, turn the automatic oiler adjustment screw counterclockwise. To decrease oil flow, turn the automatic oiler adjustment screw clockwise. While always wearing heavy work gloves, grasp the chain and pull it towards the nose of the chainsaw to ensure that the chain moves freely.
How does the automatic oiler work on a chainsaw?
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.
Why is my chainsaw using so much oil?
An overfilled reservoir can often leak oil when the saw is turned on. Check this and siphon some off if it looks excessively high. If the oil is running out via the delivery line to the bar then there is a chance that the tank vent is plugged up. If so, the chain may be running ‘dry’ during operation.
Why is my chainsaw not oiling the chain?
If you don’t see any oil splattering onto the surface of the wood, the chain bar is not sufficiently lubricated. At that point, you will turn off the chainsaw and let the chain brake go. You will remove the clutch cover and take the chain off of the bar. If the chain appears damaged or worn, that may be the issue.
How do I stop my chainsaw from leaking oil?
It’s important to note that oil tanks cannot simply vent into the atmosphere, as this could lead to the oil leaking onto the operator during use. To avoid your chainsaw from leaking oil whist in storage, the best solution is to drain the chainsaw of its bar oil and fuel mix and store the chainsaw empty.
Can you leave oil in chainsaw?
Chainsaws should not be stored with their oil and fuel tanks full. Each time that a new chainsaw or one that is very clean is run without cutting it will spread oil around the guide bar, chain and saw body in the form of a fine mist.
What happens if you run a chainsaw without bar oil?
No bar oil equals increased friction and heat. That adds up to a huge increase in chain and bar wear. Without bar oil, the chain teeth, drivers and links will all wear far more quickly. The increased friction can cause teeth to break.
Why does my chainsaw leak oil when not in use?
If there isn’t proper ventilation of the oil tank, a vacuum can occur and reduce the flow of oil to the guide bar. STIHL chainsaws use a one-way valve oil tank breathing system. This system allows air into the tank whilst the chainsaw is in use, without leaking oil onto the operator.
