On the dremel 395 there are 4 visible "star" screws holding the unit together. Get a star wrench/screwdriver and remove those. They kind of look like hex bolts, but they are not, so get the star wrenches.

Now wait.

At the neck, where you have been changing collets and tip types, You may or may not have noticed that the first inch of the top of the body of the tool, the green or grey part, can be unscrewed like a light bulb. Unscrew that, usually a good grip will do.

This now lets you see that there are 2 more smaller star bolts that also hhold the body together. remove those and you will be able to easily seperate the two halves of the tool.

Try to keep the motor body, or rather, let the motor body stay in the half that it wants to. The top shaft that ends with the collet neck, will pop out with just a little coaxing.

Between the top shaft and the drive motor, you will notice some remnent of the interconnecting thing-a majig, that is looking a little ugly right now and needs a replacement. This piece connects the outer shaft and the internal motor.

I know this because one of my first calls tomorrow is to order a replacement part for myself. And I think I will order 2. It seems as though this was not a good design development, in this series.

Good luck with your repair. I do not think it is that complicated. Pull it apart, throw out the debri, use a can of compress air for your computer, put in new part, put back in 6 screws, fire it up again.

My 5hp 13 gallon compressor won,t run when you turn it on there is no wind nothing at all how do i bypass the switch and hook it direct

you don't connect it up direct unless you want to destroy the compressor and burn the motor out
check for a reset or thermal overload button if it just shut down when over pressured
replace the pressure control switch is the best fix after checking out the motor condition

I have just purchased a Makita 8391DWPETK 18V Cordless Combi Drill - how do i actually put a drill bit in? Do I need to take off the plastic ring?

The large black part of the chuck should turn left and right to extend (close) and retract (open) the three chuck teeth that hold the bit in place. Turn the chuck to open it far enough to get your bit fully in the chuck then turn it closed to hold the bit in. When the teeth make contact turn the chuck a bit further to get it tight enough that the bit won't slip. When you get used to it, sometimes it's easier to hold the chuck lightly and turn it by lightly squeezing the trigger to turn the chuck with the drill motor.

I have a Kupa/KP36 that is making noise but the bit is not rotating. I have check the cord for power, tried different outlets. Unplugged hand piece replugged it in changed bits and still the same result....

Hi,
Sounds like the chuck holder is already worn and needs replacement.
If the motor still runs but the drill bit won't turn the problem would be the chuck adjuster( the one that holds the drill bit and tightens it ).
If the motor does not turn but there is a whining sound the problem would be the armature bushing ( it is inside the motor which the rotor/armature rotates). The armature does not turn anymore.
Fuse is out of question because the motor still have some power. Check also the motor brush.
Disassembling it requires to unscrew all the screws on the side and carefully remove the side cover, you can clean it and dust it off.
Hope that helps you out!

The fan wouldn't start for the condenser unless I turned the blades with a stick so I replaced the start capacitor and it still won't start without turning the blades with a stick. It runs fine but...

This problem could be caused by a bad motor run capacitor. Please see our If your motor capacitor is not the problem, then more than likely you need a new motor.

Drove car thru water. Car died instantaly. water was knee deep. Pushed car out of water. will not turn over now.???

when you say it won`t turn over do you mean it tries to turn over with the starter or it won`t start.if you mean it won`t turn over then when it dries out a bit(water has drained from electrical components)try it again.if it still wont then its possible it may have sucked up water into the cylinder.pull the plugs and try to turn the motor over.if it does then this is the problem.if you mean it won`t start then let it dry still for water in a component may cause electrical issues when wet.just suggestions.

My dryer won,t start. When you set the timer and turned the starter on you hear a sound that seems it will run but when you let go the starter it just won/t run

You have a bad motor. There should be a button you can press to make your dryer go while the door is open. Hold that and push the button in and then turn the drum. if that doesn't make it go then it is your motor
