But even the best chainsaw is only as good as its lubrication system. I’ve seen firsthand how a poorly oiled chain can quickly turn a productive day of logging into a frustrating, time-consuming mess. A well-lubricated chain cuts faster, lasts longer, and reduces wear on the bar and sprocket. This article focuses on the Husqvarna chainsaw oiler, specifically providing five pro adjustments you can make to improve its flow. I’ll share my experiences, insights, and step-by-step instructions to help you optimize your chainsaw’s oiling system.
Understanding Your Husqvarna Chainsaw Oiler: A Foundation for Optimal Performance
Before diving into the adjustments, it’s crucial to understand the basics of your Husqvarna chainsaw oiler. This isn’t just about knowing where the oil goes; it’s about understanding how the system works and what factors influence its performance.
Key Components of the Oiling System
- Oil Tank: This is where you store the bar and chain oil. Its capacity varies depending on the chainsaw model.
- Oil Pump: Typically driven by the engine, the oil pump draws oil from the tank and pushes it towards the bar.
- Oil Filter: Located in the oil tank, this filter prevents debris from entering the pump and clogging the system.
- Oil Line: A flexible hose that carries oil from the pump to the bar.
- Oil Outlet: The point on the chainsaw where oil is dispensed onto the bar.
- Bar Oiling Holes: Small holes on the chainsaw bar that distribute oil along the chain groove.
The Importance of Proper Oiling
Proper oiling is paramount for several reasons:
- Reduced Friction: Oil reduces friction between the chain, bar, and sprocket, minimizing wear and tear.
- Cooling: Oil dissipates heat generated by friction, preventing the chain and bar from overheating.
- Cleaning: Oil helps flush away sawdust and debris, keeping the cutting surfaces clean.
- Extended Lifespan: Proper oiling significantly extends the lifespan of the chain, bar, and sprocket.
Green Wood vs. Seasoned Wood: Oiling Considerations
The type of wood you’re cutting also affects oiling needs.
- Green Wood: Freshly cut wood with high moisture content. Green wood tends to bind and create more friction, requiring more oil.
- Seasoned Wood: Wood that has been dried, reducing its moisture content. Seasoned wood cuts more easily and generally requires less oil.
When cutting green wood, I often increase the oiler output slightly to ensure adequate lubrication. Conversely, when cutting seasoned wood, I might reduce the oiler output to prevent excessive oil consumption.
Pro Adjustment 1: Checking and Cleaning the Oil Filter
One of the simplest yet most crucial adjustments is checking and cleaning the oil filter. A clogged filter restricts oil flow, leading to inadequate lubrication and potential damage.
Step-by-Step Guide to Cleaning the Oil Filter

- Observe the Oil Output: As you adjust the screw, observe the amount of oil being dispensed onto the bar. You should see a steady stream of oil being thrown off the chain.
- Test the Oiling: Cut a few pieces of wood and check the bar and chain for adequate lubrication. The bar should be slightly wet, and the chain should not be smoking.
- Fine-Tune the Adjustment: Continue adjusting the screw until you achieve the desired oil flow.
Data and Insights: I’ve found that a good starting point is to adjust the oiler screw so that the oil tank empties at roughly the same rate as the fuel tank. This ensures that the chain is adequately lubricated without excessive oil consumption.
Original Case Study: In one of my timber handling projects, I was cutting a large quantity of oak logs. Oak is a dense hardwood that requires ample lubrication. I initially had the oiler set to the factory setting, but I noticed that the chain was getting hot and smoking after only a few cuts. I increased the oil flow by turning the oiler screw counterclockwise, and the problem was immediately resolved.
Measurement: Observe the rate at which oil is consumed relative to fuel. Aim for a roughly 1:1 ratio.
Tool Specifications:
- Flat-head screwdriver
Estimated Time: 10-20 minutes
Pro Adjustment 3: Inspecting and Cleaning the Bar Oiling Holes
The bar oiling holes are small openings on the chainsaw bar that allow oil to flow from the oil outlet to the chain groove. These holes can become clogged with sawdust and debris, restricting oil flow and leading to inadequate lubrication.
Locating the Bar Oiling Holes
The bar oiling holes are located on the chainsaw bar, near the mounting area. There are usually one or two holes on each side of the bar.
