More info about how does a chainsaw oil pump work

But how does a chainsaw oil pump work? The crankshaft drives the pump, which draws oil from the tank and pushes it onto the guide bar via the outlet hole. The movement of the chain then distributes the oil along the entire length of the guide bar.

Chainsaw oiler consists of an oil pump, oil lines, and oil holes. With the oiler system cleaned from all the debris and gunk, reassemble everything and start your Chainsaw. For electric chainsaw models, you should examine the oiler after each use and make sure it gets replenished when empty.

The next iteration of chainsaw oiler was still manual, and because it involved an onboard thumb plunger next to the throttle, it eliminated the need for a “Chainsaw caddy.” This advancement in chainsaw oiling technology allowed the operator to manually pump oil onto the bar while cutting. If the chain spits small amounts of oil onto the wood, you’ll know that your chainsaw oiler is functioning properly. As always, if you’ve got any other pro-tips on how to keep your chainsaw oiler functioning properly, feel free to leave them in the comments section below!

If your chainsaw is new or you have replaced your chain and guide bar, you will need to keep adjusting the oiler until you determine the right setting that will enable the oiler to produce just the right amount of lubrication. If the above fixes do not work or oiler problems keep recurring, this could indicate that your oiler may be damaged. To ensure that the oiler is functioning correctly, start the chainsaw and let it run for a few minutes then direct the tip of the chainsaw blade towards a piece of wood.

The oil system on a Stihl chainsaw lubricates the engine and the bar and chain. The bar and chain oil on a Stihl chainsaw originates from the oil tank on the same side as the gas tank. Stihl chainsaws use an automatic oil pump, which means that whenever the engine reaches a high enough speed to engage the chain, the pump is also activated, taking the hassle out of manually trying to engage the oil pump and control the flow of oil to the bar.

How does the automatic oiler work on a chainsaw?

The throttle simultaneously engages the motor and the oil pump. 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.

What lubricates the crankcase on a chainsaw?

A chainsaw engine uses gasoline and air-cooled engine oil to cool the engine. Oil-rich fuel will also lubricate the crankshaft and the piston when the gas reaches the cylinder, allowing the engine to continue running at high speeds while the oil-rich fuel lubricates the crankshaft and the piston.

Is it normal for a chainsaw to leak bar 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.

How do you clean a chainsaw oil pump?

Clear any sawdust, congealed lubricant and dirt out of the oil outlet hole on the guide bar. Keep the oil pump tank clean: even if it is equipped with a filter, wipe away all dirt around the cap before refuelling. Regularly check and clean the tank vent and the filter itself.

Why is my chainsaw using so much oil?

What causes a chainsaw to leak oil? As the oil is pumped from the tank through to the guide bar, air begins to replace the space where the oil was previously stored. If there isn’t proper ventilation of the oil tank, a vacuum can occur and reduce the flow of oil to the guide bar.

How much oil should a chainsaw use?

When to Oil Gas chainsaws use about one tank of bar and chain oil for every tank of fuel, so fill the reservoir every time you fill the tank.

How does a 2 stroke crankshaft get lubricated?

How Does A 2 Stroke Crankshaft Get Lubricated? While an engine two-stroke has the cylinder filled with air or fuel, the crankcase is filled with liquid. This allows thick oil to evaporate quickly. Your method is to mix oil into gas to lubricate the crankshaft, connecting rod, and cylinders.

Does a 2 stroke engine have crankcase oil?

Unlike a four-stroke engine, whose crankcase is closed except for its ventilation system, a two-stroke engine uses the crankcase as part of the induction tract, and therefore, oil must be mixed with gasoline to be distributed throughout the engine for lubrication. The resultant mix is referred to as premix or petroil.

Why is my Stihl chainsaw leaking chain oil?

This condition is deemed to be normal for any chainsaw with a similar bar & chain lubricating system. If the unit continues to seep oil after a few days, the problem may be the vacuum relief valve located in the side of the engine housing between the oil output hole and the bar stud(s).

Do all electric chainsaws leak oil?

Even after you have removed oil from the reservoir, the electric chain saw might continue to leak oil if the pump is dirty. Excessive oil on the oil pump gaskets can cause leakage. Wipe the gaskets clean and check them for wear. If the gaskets are ruptured, replace them.

Can you over oil a chainsaw?

Although a chain saw always requires the moisture that oil provides during the saw’s operation, too much oil isn’t good. When the oil adjustment is set too high, the oil is subject to drip from the chain and run down the guide bar.

Can you use 10w30 oil in a chainsaw?

As a matter of fact, you can actually use regular 10w30 motor oil on a chainsaw as one of the alternatives in case you don’t have bar and chain oil. That’s because 10w30 oil has enough thickness and viscosity that will allow it to withstand the friction that is happening whenever you are using a chainsaw.

How often should you oil chainsaw chain?

The chain saw should be oiled before each cut. For Manual Oiling System: Lubricate the saw chain by pressing the bulb on the oil reservoir cap twice before making each cut. Hold the bulb down for 3-4 seconds on each press. Automatic oiling system will keep the bar and chain constantly lubricated.

How often do you change chainsaw oil?

HOW LONG DO 2-STROKE OILS LAST FOR? Two- stroke oil will last for a couple of years when it is not mixed with petroleum. Once mixed with petroleum we would not recommend keeping for more than 3-4 months in a sealed air tight approved storage container.
