How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
The rear hand guard on the rear handle of the chainsaw is designed to protect the hand from a broken or jumping chain. A chain catcher is designed to catch a broken or jumping chain. An adjustable oil pump adjusts oil to the chain based on the blade length and type of wood being cut.
There are three main reasons for a chain to come off: Incorrect bar and/or chain for the saw; check to be sure that you are using the proper chain pitch, gauge and number of drive links to match the guide bar. Chain not properly tensioned; It is normal for a new chain to stretch and require frequent adjustment.
Pushback occurs when the chain on the top of the bar is suddenly stopped when it is pinched or caught or encounters a foreign object in the wood (Figure 6). The reaction of the chain may drive the saw rapidly straight back toward you and may cause you to lose control of the saw.

On my saw when I changed the chain out, the cover will not go back on over the clutch correctly.. The cover has a ring in it that is supposed to go over the clutch but does not fit correctly, What am I doing wrong?
You should have released the chain brake before taking things apart–it will be necessary to move the brake coupling in the cover with a wide blade, square shanked screwdriver and a wrench that fits the square shank of the screwdriver. It should make a ‘snap’ noise when fully released and the brake ring will have expanded to fit over the clutch hub. Hope this helps!
Clutch cover will not go back in place after changing chain.
The cover was probably removed with the chain brake set. Unfortunately, the brake must be reset in the cover with a wide blade screwdriver used in the coupling that connects with the handle mechanism. This will expand the brake band allowing it to go over the clutch drum. Good luck!
Took off cover to put chain on and can’t get the cover back on the brake band doesn’t sit right
You need to release the brake mechanism in the cover so that the brake band will expand enough to pass over the clutch drum. You should have released the chain brake before removing the cover, but that doesn’t help now. Use a wide heavy screwdriver to release the mechanism. Hope this helps!
How do I get the brake band ,located inside the chain cover, assembled back onto the chain saw. clutch assembly. The band brake diameter seems too small to fit around the clutch housing.
You need to load the brake, clamp it in a vice, be carefull not to damage the cover, if the hand gaurd is connected to the brake pull it fully back until the locks off, this may take a fair amount of force as it is compressing a large spring, if the hand guard is on the machine, remove it and use this as a tool to load the brake, the only other way is to remoce the clutch and sprocket, now refit the brake onto the saw, now pull the hand guard fully back to load the brake.
I am trying to replace the chain on my saw. When I try to fit the clutch cover back on the there is a metal band that does not seem to want to fit properly over the wheel, causing the chain to not move when the cover is tightened.
Your chain brake mechanism is in the “locked” position…you will need to release it. Some husky’s have the handle on the cover. If this is the case simply pull the handle towards what would be the rear of the saw and install the cover.
Other saws have the handle on the saw and some little cogs mesh with cogs in the side cover. In order to unlock this one I use two 1/4″ x 2 1/2 inch or so bolts in a vise. They get clamped with the bolts protruding vertically above the vise jaws and are spaced so the the tips of the bolt will fit in between the cogs. Study the assembly and determine the direction of rotation required to release the brake. Place the side cover face down over the bolts with the bolt tips in between the cogs and rotate until the brake cams over and releases. be sure you know which direction to rotate the cover as a bit of force is required to get things moving.
Once the brake is released you should be good to go.
My saw a jonsered 670 champ keeps putting oil out the oiler tube
even when the saw is shut off , until the tank is empty any ideas
Try loosening the oil filler cap when you are finished using the saw, this should stop the siphoning of the oil. Tighten the cap again. Stephen.
Chain came off because something jammed it. Removed cover and cleaned things up. Cannot get cover back on because chain stop band will not fit on drum.
The chainbrake has activated, you need to load the brake before it will go back on, the easiest way to do this is to remove the hand guard from the machine , engage it into the brake mechanism and pull firmly back to load it, you can also remove the clutch and sprocket, the brake will then go back onto the saw, and use the hand guard as normal to load the brake, to remove the clutch jar it off against the compression of the saw, it is a left hand thread, there is a cut a way in the clutch centre to insert a screw driver and strike with a suitable hammer.
Cant get the metal cynch to cover or fit over the clutch when i put the cover back on after changing the chain
Make sure your inertial brake is not engages before taking the cover off the saw. If you brake is engaged and then you take the cover off the side, sometimes you can get it “close enough” and use the forward brake guard to reset it (like normal) but more often than not you will need to use a screw driver to manual reset the brake on the cover before reinstalling. This can be difficult as you no longer have the added lever of the front handle…
