For petrol chain saws the brake lever is fully forward for the chain to drive
fully back locks the centrifugal clutch and the chain will not drive

You'll have to release the brake with the cover off the saw. You just need to find a way to brace it well enough.
If you really can't do this, then it suggests your chainbrake is faulty, of ath the very least not adjusted right.

I have the same model chainsaw with the same fault. The brake is not releasing when the brake handle is pulled right back. I can only run mine if the brake handle is pulled back to the main handle with a tyrap - defeats the object of the auto-brake completely. Design fault I reckon.

Mine did this when nearly brand new. You likely have a nasty jam of oil and sawdust stuck between the chain brake and the flywheel. It can be loosened by either careful prying of the case or precise shots of carb cleaner up in the housing. While you are in there look for a buildup of oil around the chain brake connection to the kickback paddle.

my guess is that you have a crack or a hole in one of your fuel lines. this is very common in chainsaws and weed eaters because they are used very little and sit for a long time. try checking this and repair if necessary. let me know if this works.

You will need to release the brake by applying a very heavy screwdriver to the + shaped part of the brake coupling. Check the action of the brake handle and duplicate it at the the +. Hope this helps!

On Homelight 3816c what is the position position of chain brake when cutting


Easy enough to test which position is correct. With the saw not running of course, Try each position the one where the chain moves freely is the correct position. Most likely on this saw it will away from the bar (rearward).

Chain brake not working right


strip cover and check that all the dirt etc is cleaned out and the brake band is in the correct position If the brake band looks worn ie thin in places replace with new one. Dirt can also get in the pivot of the chain brake handle and cause it to jam, saw should be stripped and cleaned at the end of every days use and the bar turned over to even out the wear

I just started up my new 16" Homelite and the engine starts, but the mechanism that powers the chainsaw isn't rotating... any suggestions?


The engine needs to be accelerated to make the chain turn. The chain should not be so tight on the bar that you can't turn it by hand. Make sure the chain brake is off by pulling back on the brake paddle which has a 'toggle' effect--it should snap over to the new position. If still having problems, it is time to return for warranty exchange or repair. Hope this helps!

My chain saw (14 inch gas powered) would not


Modern chainsaws have the ability to run without turning the chain via the chain-brake. To set the brake the uppermost handle is pushed forward (toward the chain) and a firm snap should be heard and felt. To release the brake you pull the same handle back (towards the engine) and get the same "snap".
Concerning oil leakage: Bar/chain lube collects on the inside of the clutch cover and the sawdust mixes with it as you saw. A surprising amount of oil gets absorbed in the sawdust and later seeps back out when the saw is at rest. If the level of oil in the tank noticably drops after sitting overnight you may have a leak...otherwise it's normal.
As for a running chain that wont cut, it is common for chains to be installed backward and the unit still function perfectly (it just won't cut wood). See the proper chain orientation here. In this photo the chain travel is from left to right.

My chain saw will start and idle fine, however the chain will not spin and if you try to give it gas the engine will begin to smoke like its running hot and stall out


Your chain may simply be too tight or the brake could be on. Pull back on the Kick Back bar in front of the handle and with the saw not running try to rotate the chain by hand. If it will still not rotate losen the bar mounting bolts and turn chain set screw out a little at a time until chain turns. Retighten and recheck chain. The chain should be able to be pinched from the bottom of the bar, but snap back in place and rotate by hand. Caution chain wil be sharp use gloves or heavy cloth when turning. If all this works out and you still have same results, mix up a new batch of gas/oil and drain saw's tank and put in fresh. Should work now hopefully. Also, one other thing to look for when a saw's chain will not turn is debrie jammed into the sprocket area. In which case may have to take chain and bar assembly apart and clean and then reassemble. God Bless

Fly wheel seemds locked up on Husqvarna 445


the flywheel does not have a brake,the clutch side has the break.if you have the chain side cover off the brake is no longer on the clutch drum.the fly wheel is on the oppiset side (starter rewind).take the starter rewind off and see if the motor will turn.if hte motor turns the problem is in the clutch side.if it doesn't the problem is in the flywheel side.the ignition coil has been known to loosen up.the screws streitch out from heat.check the air gap between the flywheel magnets and the ignition coil.should be .10 to .12 inches.if problem is on clutch side check to make sure that the springs are on between the clutch discs.they have been known to break and that does not let the chain spin on bar.any questions get me an e mail
