The bar bolts on this saw are fed in through the oil tank. Push out the damaged bolt. wrap a thin piece of wire around the new bolt's threads leaving enough wire to feed through the open hole in the case. Pull the bar bolt through the hole until you can grab with your fingers. Using bar bolt, start pulling the bolt through the hole, add washers and continue to tighten until you seat the bar bolt.

Heat shrink wrap not electrical tape since it can peel away
New cord longer is better in my opinion
Wire cutters
Or Wire extension or splice adapter
If the wire is brown copper use a new copper wire if it is silver aluminum use a new aluminum wire.

Malibu power packs are 1-piece units that can't be taken apart.
However you can cut off the cord and leave about 4-6" of cord sticking out, and then splice into the cord that's sticking out.

Usually I buy heavy orange or black extension cord with male-female plugs on each end.
I cut off female end and use that end to splice into the cord that's sticking out.

How to splice wire.
Use knife and slice down the cord lengthwise... just cut through the outer plastic covering.
Pull the outer cover cover back to reveal black and white wires.
Cut off extra cover.
Cut back insulation on each black and white wire.
Now you have 2 black wires and 2 white wires/
Twist together the copper wire on whites and cover with plastic electrician tape.
Do the same with copper wires on blacks.
Now the blacks are joined/ and whites are joined, and each has tape over copper wire.
Wrap black tape around both sets of wires until all the black and white is covered with several wraps of tape.
That's it. Plug it in.

If when you try to close the door the main light flashes 10 times and the door reverses to the open position you have a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not flickering. If you cannot get both lights to come on you have a bad sensor.

Very easy, if you don't care how pretty it is. All you need is a sharp knife and some electrical tape. Use the knife on each end of the cord to expose 1/2" of copper wiring, twist them together, cover each wire separately with tape, then wrap several turns of tape around the whole thing.
