To tighten the chain on a fixed-gear bike, start by flipping the bike over or placing it on a bike stand. Loosen the rear axle and then pull back on the rear tire to make the chain tighter. Make sure the chain isn`t too tight or too loose, then tighten the rear tire again.
Probably the most common cause of a chainsaw chain that won`t tighten is the tensioner screw simply not doing its job. This could be due to various reasons. But 90% of the time, it happens when the threads on your chain tensioner screw get stripped.
Chainsaw chains stretch during normal operation and begin to sag on a saw`s guide bar. If a chainsaw chain is allowed to become too loose, it can easily come off the bar during operation and create an unsafe situation for the user. Chainsaw chain tension should be checked and tightened often.
Saw chain that is too tight can prevent the chainsaw from turning the saw chain or cause the chainsaw to heat up. In addition to being a potential fire hazard, an overheated saw chain and guide bar can significantly reduce the useful life of these components.
A decompression valve releases some of the compression from the combustion chamber during the starting procedure, making the engine easier to turn over when pulling the recoil rope.
This is how it works
Turn the little adjusting knob above it anti-clockwise to slacken the chain, or turn the knob clockwise to tension the chain. The guide bar is automatically secured in place when the sprocket cover is re-tightened.
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.
Pull your chain down and measure the distance between the centre of the chain and the sprocket. Lift it to its highest point and measure the distance again. Find the difference between these two measurements and – voilà! You`ve got your chain`s tension.
The rule of the thumb says that the exact tightness of a chain will only let you move for about half an inch. Now, if the chain is too loose, then you need to tighten it. If you cannot even move the chain, then it is too tight, and it needs to be loosened.

Normally, a loose chain will enhance it’s ability to jump off when trimming small branches.When installing and/or adjusting a chain;1) install the chain, bar, and cover, and install the cover nut loosely2) support the ‘nose’ end of the bar with a block3) tighten the chain until it touches the bottom of the bar, and then tighen the adjuster 1/8 of a turn more. *this will make the chain just a LITTLE snug4) tighten the cover nut, and then by hand CAREFULLY rotate the chain. If you cannot rotate by hand, it is too tight. re-adjsut
** This proceedure must be used on ANY brand chain saw. Here is why. If the bar nose is not lifted upon adjustment, when cutting, the nose will move upward, the chain will have a ‘droop’ away from the bar and appear to have loosened while cutting. Any contact with a small branch will flip the chain off of the bar. If you re-adjust it improperly, the same senerio will occur the next cut.
Chain saw chain is loose
Loosen the side cover nuts, then turn the adjuster CW to bring the chain up to the lower edge of the bar, then check to see if the chain will move fairly easily by hand. Tighten the clamp nuts and recheck tension. If chain seems to get loose quickly again, it may not be sharpened correctly causing heat to build in the chain. You should see no reflection of light from the cutting edges if filed correctly and the saw should require very little pressure for it to cut rapidly. Hope this helps!
I can’t tighten the chain. I turn the wheel to tighten it, but the little catch that fits in the hole on the bar does not move. the wheel turns but the chain remains loose
