Loosen the base clamp lever on the side of the housing and rotate the thumb wheel under the motor housing. The base will come off.

seem like electrical problem, this is new model and should be still under warranty, i would suggest return it to place of purchase and replace/repair

There are a couple problems that could cause this. First is the trigger switch which could be worn out or have a short. The second and more common one is that the motor brushes are worn out. After a long period of use these little blocks that look like black steel blocks on springs are what rub on the rotor and they wear out. These are not steel but special high carbon blocks that are easily replaced and cost effective. Remove the housing and near the rear of the motor assembly you will find the brushes in two square holes on either side of the motor. Remove them (be sure it is unplugged) and replace them with new ones. They can be ordered directly from Bosch or from a host of suppliers on the internet.

open it up and clean all the dusk inside. probably it's stuck and can't start the mechanism. That's what i did with mine. Working perfectly again.

The socket-head screw that holds the sole plate on is also the alignment screw. Loosen it a little and the sole plate will swivel left and right. There are graduation marks on the base to help with alignment but I always use a square to verify the alignment. Tighten the screw and check again that it didn't move and you are ready to go.

I'll be honest with you and say that if the saw is not under warranty and you need to send it out for repairs, it is unlikely that you will get it repaired for an acceptable price. The parts from Bosch are very expensive and if you need to pay a repiar person on top of the parts you will likely spend more than the saw is worth. I recently purchased a damaged one online and used the parts to fix mine and it was still more than I wanted to spend plus 4 hours of my night tearing apart a very intricate saw - not for the novice.

There are terminals located inside the rear housing of the saw. To get at it you need to remove the back cover with a single screw on the back of the saw. from there you should be able to see the terminals with female spade connections.

When doing any straight cut use a straight edged piece of something to run the jig saw along, using as a guide, this will usually keep it all straight, sometimes it can be a loose blade, or a bent shaft?

No safety or reset. The problem is likely to be a bad connection somewhere inside the jigsaw or dust around/inside the trigger assembly. If it is new or recently purchased, seek a replacement. If out of warranty, you could try disassembling it and checking for loose wires, or using an appropriate multi-meter to check where the current is absent and go from there.

The problem is the switch, or trigger switch. It may just have saw dust in it or it may be shot. Try blowing the dust out of it with a good blast of compressed air. If you don't have a compressor to do this go to a tire shop. They will help u.
