Chain keeps coming off - Remington Electric Chain Saw

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 loosely
2) support the 'nose' end of the bar with a block
3) 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 snug
4) 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.
