Question about Poulan Pro Chain Saw 46cc 20"

2 Answers

Chain keeps falling off

My poulan pro 20 (46cc) has very little use (about 10 hrs).
The chain yesterday kept falling off during sawing. i thought it may have been too lose the 1st time but the 2nd and 3rd time i am sure the tension was not the issue. The bar appears straight.
So, for the last time i tightened it too much. i started it and ran it without sawing. In 10 secs, the chain fell off again.

i did notice that when putting the chain back on, the chain itself is not close to the bar side of the gear but it actually was found to be resting on the other side in the 'gap' between the gear and the wall of the body.

Why is the chain falling off?

Have you stripped the studs that hold the guide bar in position? It is the only thing I can think of unless the guide bar has worn down so much there isn't a deep enough groove to guide the chain

How to tighten chain on 4620avx poulan pro


First, RTFM- read the manual. Lost it? No problem, download it from Poulan PRO website page for PP4620avx. Pick a version you like, save and read it. Google is your friend.
Chain Adjustment Part cut and pasted as follows:
Adjusting the tension:
Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.
1. Lift lever on bar knob and turn counter-clockwise 1.5-2 turns to loosen clutch cover.
2. Turn adjusting wheel (downward direction) to tension chain until chain solidly contacts bottom of guide bar rail. Lift tip of guide bar while adjusting tension. Tighten chain Adjusting Wheel
3. Use a screwdriver to move chain around guide bar to ensure all links are in bar groove.
4. While lifting tip of guide bar, tighten bar knob securely (clockwise).
Hand tighten only.

Be careful not to destroy the adjustment mechanism. When it breaks, go for a clutch cover with the simple adjuster that needs a "scrench". Longer term, learn how to search this info. Saves time. Now you can work on sharpening chains- very important.

The chain keeps falling off my brand new Poulan sixteen inch blade chain saw


It is possible they gave you the wrong chain for the saw. I would take check the manufacture to see which chain you need then check the numbers on your chain. Other thing it could be is the washer on the clutch may be missing. Either way, it is a new saw, I would take it back.

Check the machine is oiling ok, if there is not enough oil to lub the chain it will stretch causeing it to come off, you should see a good spray of oil from the tip of the bar when the saw is reving.

Chain falls off Poulan PP3516AVX


The bar needs to be adjusted. What this means is the long, sliver arm that sticks out and has the chain wrapped around it is in too far. You will need to find what is called a 'set screw' or 'set bolt', which you can loosen and then adjust the bar in and out, which will tighten or loosen the chain. Keep in mind that you should have a little slack on the chain or you will burn up the bar. Also, make very sure that the chain is good shape. A chain that pops on you can take an eye out or fingers off of your hand if you're not careful.

Chain keeps turning while in the idle position . Poulan Pro 2075 chain saw.


There will be an idle (Low) speed adjustment screw somewhere on the saw (look in your manual). Adjusting this setting lower will prevent the chainsaw chain from turning in the idle throttle position. Basically you want to set it so the chain has just stopped moving... but you need to set this after the chainsaw has warmed up a little.
