    With a new chain that is not excessive. By side tensioning do you mean tool-less, or is the adjuster between the bar nuts?

What is happening is the chain is heating, and expanding.
Make sure you have a full tank of oil, and the recommened blade for your saw.
Also make sure the bolt(s) are not damaged on your adjuster.

Husqvana 435 chainsaw comes loose after 5 minutes nof use ?


if it is the chain that comes loose, loosen of the blade lock nut and adjust it with the screw under the blade
the proper tension of the chain is achieved when you pull the center of the chain up and the clearance to the blade is around 1/16 inch( leaving the inner section of the chain still in the blade guide
retension the lock nut

I have a huscavarna 435 chainsaw and after running a few minutes the chain locks up


You may have the chain tensioner set a little too tight.

Additional things to check:
  • The sprocket on the end of the guide bar is greased, and turning smoothly.
  • The chain brake is working correctly (not dragging or only partially disengaging).
  • The guide bar is straight, not bent or twisted, burr free, and the groove the chain travels in hasn't been squeezed together.
  • The chain tension is set correctly.
  • The chain oiler is functioning correctly (and you have a sufficient amount and correct type of bar oil).
  • Chain is in good condition, and the correct one for the saw. Make sure all of the links flex smoothly.
  • Chain is sharp. A dull chain will put more pressure on the guide bar because the cutting teeth aren't digging into the wood efficiently (and usually a person pushes harder on the saw when the chain is getting dull).

How to remove the chain from a husqvarna 235e chainsaw?


Like this or pretty close.





  1. Cock brake while expanding chain brake binder by pulling brake handle towards left-hand (wrap-around) handle grip, hard, until it locks in place.


  2. Loosen 2 brake-asssembly-and- bar retaining nuts but do not remove yet.


  3. Unscrew (turn CCW) bar adjustment screw on front face of unit in order to shorten bar and slacken saw chain.


  4. Slip chain off bar over bar tip and towards inward side of bar.


  5. Remove two nuts loosened in step 2 and pull brake assembly and bar straight out and off bar mounting studs.


  6. While rotating clutch/brake-drum, maneuver saw chain off sprocket and around drum perimeter to remove from saw.


  7. Repeat/reverse steps 6 thru 1 in that order to reassemble.

Adjusting chain tension


There are a number of different types of adjusters, front manual adjusters, side manual adjusters and tooless adjusters, the two latter systems require you to slacken the bar nut/nuts and with a flat blade screw driver turn the screw clockwise to increase chain tention, the chain should touch the bar rails all around the bar with no sagging on the under side of the bar, with a gloved hand you should be able to pull the chain around easily to make sure its not too tight, with the tooless adjuster slacken off the bar nut/nuts and turn the thumb wheel down to increase the tention.

Change the chain instructions


General instructions are, if the machine has a chainbrake make sure this is off, loosen the side cover nut/nuts, wind the bar adjuster screw back to slacken the chain, remove the side cover, push the bar back to the sprocket, the chain should now be lose enough to lift it off the tip of the bar and un loop off the sprocket, now loop the new chain over the sprocket and around the tip of the bar, make sure the cutters on the top of the bar are facing away from the saw ( a pushing chain )now re fit the side/chainbrake cover, if the bar adjuster pawl is in the brake/side cover, make sure this aligns with the adjuster hole in the bar, re fit the bar nut/nuts finger tight, wind the adjuster screw in so as the chain sits snuggly all around the bar, with a gloved hand pull the chain around the bar manualy, it should pull smoothly, lift the tip of the bar up and fully tighten the nut/nuts, run the saw, there will be an amount of initial stretch, slacken the bar nut/nuts and re tention.

How do you set the chain tension on a 345e?


The E version is tooless, so flip out the wing in the centre of the big cover fixing nut,slacken the nut off half a turn, now turn the knurled adjuster in the side cover, down to tighten, up to slacken, there are many schools of thought about the correct tention of the chain, but basically the chain should sit snuggly all round the guide bar, and with a gloved hand pull manually around the bar with out too much force, it should never sag on the bottom of the guide bar.

I am replacing the water pump of my 1995 3.0 v6 infinity (same as altima) but my son removed the chain with out marking it, now I need to set the timing. How do I do this? There's marking on the valve...


This should be the same engine as the Maxima. If that is the case, there is no reason to remove timing chain or get it out of time. The pump is driven by the timing chain, but is not "in time".

The pump is under its own cover. The chain tensioner is under its own cover. The pump is removed after the tension is released on the chain, the tensioner pinned in its retracted position to take tension off chain, and the crank is rotated about 20 degrees counter clockwise to slacken the chain at the pump sprocket without coming off the cam sprockets. Then, the pump is remove by removing its mounting bolts and then screwing in three long M8 bolts as jack bolts into 3 holes (carefully and evenly) to jack out pump. The pump is sealed from the engine case by two o-rings that must be replaced. I think the pump mount bolts are sealed with silicone when replaced. I would get a Haynes or other reliable manual.

If you truly have to reset or check timing, definitely get a book.
