Replace the oil pump..Or just try to clean it out but I have been through this and it worked for about ten minutes and I ended up just replacing the pump and works fine now. They are not very expensive (35.00-40.00) and only takes about ten minutes. Get a beer and a table or the tail gate of you truck should be fine. Take off the side cover remove the bar and chain. Clean everything up... air compressor is best a paint brush and rag works good if you do not have a air compressor. Take the top plastic cover (three screws on top of the saw). Pull the spark plug and feed a piece of rope into the cylinder. This will bind up saw so you can remove the clutch. I use a pull start rope from my old lawn mower and keep it in my saw box for this reason. This size and kind of rope seems to work best. Now you need to remove the clutch. There is an arrow on the clutch that tells you which way to turn it to get it off. This can sometimes be tricky but don't give up. I'm sure there is a tool for this and I keep saying that I'm going to make something. I use the handle of a good strong pair of pliers and turn the plier with a pair of vice grips. When you see the clutch you'll figure out something to use to loosen it and spin it off. Un-spin the clutch and remove the clutch drum by just sliding it off the spindle. Be careful because there is a bushing with needle bearings. The bearings are in there pretty good and wont just fall out. If you want to replace that you can 14.00 or so. There is also a plastic drive gear for the pump that just lifts out , replace it too 6.00 or so. Take off the metal cover I think it's just one screw. When you remove the cover you may see a lot of saw dust and oil all packed inside. If you have an air compressor just blow it all out. The oil pump is right there and is simply removed with one screw. clean every thing up put the new pump in put everything back together and you should be back in business.

Drain out all the oil. You will have to have a air compressor or find some one who does. With a rag to help cover the fill hole pressure the oil chamber and push the oil valve open and try to blow out the clog.

An IPL for a CS4400 Chainsaw can be found here (there are multiple IPLs, please ensure this is your saw):
There is no sigle illustration of all oiler components, they appear on multiple illustrations.
From the IPL it has an outboard clutch, it appears the oil pump is behind it. Use this a guide for clutch removal:

Most often there is a dust-oil clog in the bottom of the bar slot which closes an oil passage between the bar slot and the hole drilled half way through the side of the bar. This provides a passage between the thin shim plate with the two bar bolt holes beside the bar and through to the oil tank or pump output. You can remove the bar and chain and punch out the blockage in the bar with a paper clip if the chain is removed. Make sure the wire can be pushed from the bar slot right through the side hole in the bar. A gravity feed chainsaw should leak right out into the slot of the shim plate, a button pumper should squirt out there with the bar removed. With a button pumper you may have a tiny check valve in the line or the push button to take apart, replace the spring or unstick the ball inside the check valve. This is why they went to the gravity feed oil system which just leaks in there and gets picked up by the bottom of the links as the chain races past the passage between the bar side hole and the chain slot.

Testimonial: "I checked as you suggested and I removed the pump from the crank shaft and the plastic gear is stripped. Now I can not find a pump. Thanks Jim"
