These are the causes of a chainsaw leaking bar oil:

  • Exceeding the capacity of the oil tank
  • The guide bar exudes oil
  • Accumulation of oil leak in indentations
  • The formation of oil pump droplets
  • Engaging in running without pauses or breaks

Let’s find out each of these causes elaboratively and how you can solve them.

1. Exceeding the Capacity of the Oil Tank

If a tank is pushed too hard and filled beyond its capacity, it can create pressure that causes it to leak. This often occurs when too much sawdust accumulates in the housing or if high-viscosity oil is used. Additionally, damage to the neck seals surrounding the bar oil reservoir could ultimately lead to leakage. To avoid these problems, regular maintenance, such as cleaning out sawdust and checking seals, should be performed.

2. The Guide Bar is Exuding Oil

A leaking chainsaw bar oil can be caused by a variety of factors. Most commonly, it’s due to either improper lubrication or a worn guide bar. Improper lubrication involves using the wrong type of bar oil for your specific make and model or inadequate maintenance that causes air pockets in the system. Worn guide bars typically break down from extended use and age, resulting in cracks and an inability to properly contain the pressurized oil inside. If you notice that your chainsaw bar is exuding oil, it’s important to address the issue as soon as possible to minimize further damage to your chainsaw.

3. Accumulation of Oil in Indentations

A lack of lubrication and wear on the seals may result in the oil seeping through and causing leaks. In other cases, there may be aging, damage to the seals, or wear due to overuse which will lead to similar results. Furthermore, on some occasions, the accumulation of oil can occur in certain indentations on the chainsaw’s bar, which could then eventually cause leaks.

4. The Formation of Oil Droplets 

One of the primary causes of leaking chainsaw bar oil is the formation of oil droplets. These droplets form due to a build-up of pressure within the saw’s chamber caused by oil residue and dirt, which can lead to leaks in various parts of the chainsaw, such as around its bar or via small holes. This kind of leakage is often caused by failing to clean and maintain the chainsaw regularly. If left untreated, this can cause serious damage to the machine over time, making regular maintenance essential to getting the most out of your chainsaw.

5. Engaging in Running Without Pauses or Breaks

Some of the most common reasons for bar oil leaks are improper use or minor damage caused by bumps and impacts. In addition, the chain brake can become blocked or frozen over time if it is not cleaned regularly, which may lead to bar oil leaking. However, one of the biggest reasons for bar oil leakage is when the user overfills the tank with bar oil. This can cause pressure build-up in the tank that forces excess fluid out through any small openings or abrasions in the system leading to leakage. Poor maintenance and improper storage can also contribute to a leaking chainsaw bar oil and engaging in continuous running without pauses or breaks.

How Bar and Chain Oil Work?

Bar and chain oil is a must-have for a chain saw operator. It plays an important role in keeping chains working smoothly and safely. When oil is applied to the chain, it keeps the metal parts from corroding and lubricates the components of the chain saw so that they do not overheat or cause friction. Additionally, bar and chain oil helps prevent the build-up of dirt and debris, which can harm both the engine of a chain saw and its user. Bar and chain oil must be applied to a clean surface before use on a saw to ensure it functions properly and efficiently.

Understanding the Significance of Lubrication

Knowing the importance of lubrication can be an essential part of keeping vehicles and machines running smoothly. As most mechanisms tend to generate numerous amounts of friction with their regular use, certain parts end up wearing down quickly or can even break. Lubricated surfaces protect these components and help maintain the functionality of metals and other materials. Furthermore, lubrication has been proven to reduce operating costs and energy consumption, as well as provide safety tools for workers. All in all, understanding the value of having a properly lubricated system is key in sustaining a functional machine or vehicle.

Instructions for Proper Venting of Chainsaw Oil Tank

Properly venting a chainsaw oil tank is an important safety step that must not be overlooked. It is essential to ensure that the gasoline used in the chainsaw does not form a combustible vapor and causes hazardous conditions.

  •  To do so, use high-octane fuel in the chain saw the tank, as this reduces its likelihood of forming combustible vapors.
  • Next, equip your chainsaw with an intake valve between the oil tank and the engine for optimal venting.
  • Make sure to adjust it regularly to ensure effective venting of any combustible vapors.
  • Also, take note to only fill your tank with oil up until two-thirds full while leaving one-third of the space in the top open for proper ventilation of fumes.
  • Following these steps can help ensure that you exercise caution and stay safe while operating your chainsaw.
