How much bar & chain oil do need each time you use the machine

Do NOT use lightweight motor oil for that bar! Use only bar/chain oil for it - nearly any brand will do just fine, but it needs to be bar/chain oil. Bar/chain oil is specially formulated to stay on the bar & chain in use - motor oil will fling away & your bar won't get the lubrication it needs.

For fuel mixing, use nearly any brand of 2-cycle oil, which is specially formulated to provide lubrication even when it's mixed into your fuel. Use about 3.2 ounces of 2-cycle oil per every gallon of gasoline - a little more won't hurt (it'll make the saw smoke a little), but never use less. Always shake the gas can just before you refill your saw's tank - shaking helps make sure the oil & gas are well-mixed.

Hi khipiercy...
You will use "Bar and Chain Oil" for your chain and bar lubricant...it is specially formulated to be used on chains and bars of chainsaws...
You can buy it at any Loews,HomeDepot, Ace Hardware, etc.
Please take time to rate me

CHAIN OILER See Figure 18. ? Use Premium Bar and Chain Lubricant. It is designed for chains and chain oilers and is formulated to perform over a wide temperature range with no dilution required. ? Remove the cap and carefully pour bar and chain lubricant into the chain oiler tank. ? Replace the cap and tighten securely. ? Check and refill the chain oiler tank every hour when using an electric power head or every time the engine is fueled when using a gas power head. NOTE: Do not use dirty, used, or otherwise contaminated lubricants. Damage may occur to the oil pump, bar, or chain.

The oiling on this model has been an issue for a long time, the first and main problem was distortion of the bar pad due to heat from the muffler, and the ommision of a metal strengthener in the pad itself, what happens then is as the bar nuts are tightened, the bolts try to pull throught the bar pad, this creates a bulge around the bar bolt and causes the delivery tube to collapse, there was a later crankcase with steel inserts around the bar bolts to prevent this, and an updated delivery tube, you can tell when this has happened as the oil drips onto your shoes rather than going onto the chain, let me know it you need any more advice or i have not explained this very well, what has the dealer said about the oiling problem?

That's for the bar&chain oil. It dribbles onto the chain as the saw runs, lubricating the where the chain slides over the slot in the edge of the bar. Without this oil the chain & bar will overheat pretty quickly, ruining both the bar and the chain.
Good luck

No. Bar & chain oil is made so it will stick to the chain and lubricate and it can deal with the heat generated by the chain. It's also thick enough so it won't run freely out of your saw. It doesn't really make any difference who makes it, just that it's bar & chain oil.

Is it new (return it!)? Did you put bar and chain oil in the reservoir?

1. Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar) Clean the saw’s oiler hole and channel. Start the saw and see if it oils when revved up. If yes reassemble your saw. If no, continue with 2.
2. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out (clean or replace, difficult to determine serviceability). Work your way through the linkage cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is a left handed thread). Please make extensive notes & some digital pictures will help during reassembly. GL

Providing a make, model & serial numbers help us help you. Without these we can only provide a general answer. There are in excess of 5000 different chainsaws.

First thing check the feed hole through which the oil is delivered to the bar itself for debris,secondly the worm gear turning the pump shafft need only be slightly damaged to hamper full oil flow , next take the oil filler cap off, (with the bar ,chain ,bar plates, and oiler removed ) look where the oil pick up is in the case half and remove it and check for clogging and / or tears in the rubber hose,
if the cap is equipped with a breathing filler cap check make sure the cap breathes this will also hamper maximun oil flow capacity,
I stand by this , as I have dealt with product for close to 2 decades and know it intimately
