Question about Poulan Pro Chain Saw 46cc 20"

3 Answers

I just bought a Poulan 16'' chain saw with quick adjust chain tensioning. The chain seems to loosen after a short time of use and the chain comes off. Quite disturbing.

1. It is common for a new chain to stretch. that is probably what occurred
2. I'd hold the tip of the bar 2-3" above a stump or even a news paper, rev it up for a few seconds and look for a line of bar oil. If none is visible your bar oil reservoir is empty or saw isn't oiling. If you added oil and it's not oiling return it to where you purchased it.

When tightening chain hold the tip of the bar upward as you snug up your chain . you don't want it too snug . after snugging you should be able to pull down the chain,on the bottom center of your bar and be able to see three of your drive links.After this is done and your bar nuts are tight give your chain adjusting screw an additional 1/8 turn more tight. This will alow you to cut wood for alonger period of time and as your saw is running and chain is getting more loose the 1/8 additional tighening will tighen the chain a little more from the saw vibration. Good luck

Yes it is. The best I can suggest is to tighten the clamping screws as best you can.

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.

How to take chain off poluan pro saw


Before putting your hands near saw chain cutters, put leather gloves on. Cutters sitting still can still draw some blood.
Loosen the nuts holding the clutch cover, loosen the adjuster, then remove the nuts. Remove the cover. Slide the bar along the studs, free of the adjuster, toward the clutch. Revove the chain from the bar groove, then move it clear of the clutch drive. It's now off. Good time to clean bar grooves and bar-mounting area of dirt & chips.
Reverse the procedure to install a chain, making sure the cutters have their cutting edge facing forward on the top of the bar. Make sure the adjuster is engaged with the bar before tightening the nuts at all.
Holding the bar nose up, tighten the adjuster until the chain touches the bar on the lower side. Tighten nuts.
After short run to clear any debris, recheck the chain tension.

How to adjust tension on 1420


Loosen the bar mounting nuts, then turn the adjustment screw CW until the chain comes up to the lower bar edge, but can still be pulled by hand. Tighten the mounting nuts and recheck the chain tension. Make sure the chain is being oiled and is properly sharpened. Hope this helps!

Chain will not move on chainsaw


Normal 0 This will be the basic instruction for most common saws. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle if the saw is equipped with a chain brake on the handle. Loosen the bar nuts on the clutch cover. Loosen tension screw or other adjuster (thumbscrew) to allow the bar to be moved toward the engine. Some saws have this tension adjustment built into the bar. This will provide enough slack in the chain to able to reinstall it. It may be necessary to remove the side cover to gain access to the clutch/gear assembly on the side of the engine if the chain also jumped the gear here. Remove the cover, inspect for any debris or other obstructions in this area. If none, replace the chain back over the drive gear and in the bar groove all the way around the bar. It may be necessary to turn the bar adjuster screw more to provide enough slack in the chain to do this. Once the chain is in place reinstall the cover and bar lock nuts. Snug up the nuts but do not tighten these. Turn the bar/chain adjuster screw to tighten the chain on the bar (take up slack). I usually tighten to a point where there is no slack between the chain and the bottom of the bar and I can still turn the chain easily around the bar by hand. With experience you will get the feel for this chain tension. Once the chain is properly tensioned, tighten the bar lock bolts/ nuts on the side cover.


Some Poulan Pros have an adjuster screw on the front of the engine case right beside the bar, some have a tool less adjuster on the clutch cover, and some have a slot in the bar for adjusting the chain tension.


I hope this helps you out.

Tighten chain?


Depending on the model, you adjust the chain tension using the screw that is located either between or below the two nuts that hold the sprocket/bar/chain cover. Loosen the nuts and turn the screw clockwise to tighten, counter-clockwise to loosen. Once you have the tension set, lift up on the bar from underneath and tighten the two nuts. Proper tension should show about half of the chain drive, and should only be done when cold. After 4 to 5 minutes of run time, stop the saw and check the tension again. A little heat in the bar/chain will cause it to loosen up. It will need re-adjusting.

Chain on a Husqvarna comes loose and/or off...once and awhile the tightening nut seems that it won't tightening down and stay


First, if the chain is getting hot it will get longer making it seem like it is loosening up, if this is the case turn up the chain oil adjustment, and make sure that you loosen it up before you store it as the chain will shorten as it cools and can put a lot of stress on the engine bearings.

Next, If it is a new chain they can stretch as they break in, you will have to keep adjusting it for a while as this happens.

Finally, the two nuts that hold the bar on the saw should be plenty to keep the chain tight. if the bar is moving inwards you might be putting too much stress on the chain, try getting your chain sharpened by a pro at a saw dealer or cutting a bit slower if it is sharp, you know let the saw do the work.

Be careful, the chain coming off can really ruin your day.

Chain keeps coming off Poulan 2150 woodsman gas chainsaw> Common causes?


The most likely cause is a loose chain.
Chain Adjustment
  1. Make sure the chain brake is off (gloves will protest your fingers).
  2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They do not need these really loose - finger tight will do.
  3. Ease the tension adjustment until the chain is obviously loose.
  4. Using one hand, hold the nose of the bar up.
  5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
  6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.

Is it fitted with a tool less adjustment device? See Operator's Manual. Normal configuration as below:

POULAN CHAIN SAW MODEL 1420 ''Chain came off track


Chain is probably stretched. SAFETY FIRST. Electric saw, make sure power is unplugged. Gas saw, make sure sparkplug wire is removed. Remove the cover where the bar is attached to the saw. U should see an adjustment screw for chain tension and one or more bar lockdown screws. Loosen the lockdown screws and turn the tension adjustment screw to permit the bar to slide back toward the motor. Put the chain back in the bar track all the way around. Adjust the tension screw to tighten chain enough you can't pull it out of the track at any spot. Slide the chain by hand at least one complete revolution feeling for any rough spots. If it moves freely, turn the tension screw enough to tighten the chain properly. Correct tension should allow you to pull the chain appx. 1/16 to 1/8 inch from the bar. Tighten the lockdown screws, replace the cover. Rotate chain by hand a couple of revolutions again to check for smoothness again before starting the saw.

Chain slips off bar


I would suggest adjusting the tension and cleaning and debris along the chain path (guide bar).

Here's the manual for Poulan PP4218AV =>

Look at page 6-7 for instructions to adjust the chain tension and page 16 for cleaning the guide bar.
