Generally speaking, the chain should be a little loose on the chain saw guide bar, but not loose enough that the drive links come out of the bar nose. The bar links should feel like they are raising up, but not actually come out of the guide bar. Testing the tension of the chain is a fairly easy task.
Most bikes will have a lock nut and an adjustment nut. First, you`ll need to loosen the lock nuts on both sides, and then you can start using the adjustment nuts to tighten your chain. When tightening your chain, only move the adjustment nut a quarter turn at a time, then do the same on the other side.
T Screw – Next, locate the T screw. This adjustment screw is responsible for adjusting the chainsaws idle. Begin by turning the T screw clockwise until the chainsaw chain begins to move. As soon as you notice it moving, turn the T screw counterclockwise slowly until the chainsaw chain stops.
Force, which in this case is chain tension (since that is how the pedal force is transferred to the rear wheel), is torque divided by radius (i.e., force = torque/radius).

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!
