Can't remove the blade from Milwaukee grinder. It seems very akward to hold the button down and turn the wrench at the same time. The bolt may be on too tight, as the wrench started to bend while trying to turn it. We also don't know which direction it turns. Thank you for your HELP!! Linda

UNPLUG THE SAW first!! Look for the blade lock on the top or front of the motor body, Hold the lock button down while turning the blade nut with a wrench. After a bit you'll feel the lock button engage and hold the blade firm. Rotate the the wrench counter clockwise and remove the nut, Slide the blade out from under the guard and replace with a new one. Reinstall the nut following the above procedure.

braun grinder blade replacement

unplug the saw/remove battery
press the button on the side near the blade
pull old blade out. push new blade in, release button to lock new blade in place.

Most petrol cut off saws have a 13mm bolt securing the blade.

On top of the head there is a button to press to lock the blade arbor. Press it down and turn the blade by hand until it locks in place. Then you need either a spanner wrench or nut wrench depending on which arbor nut you have. Grinders usually come with whichever wrench they need. Most grinders have an arbor nut with two or four holes and require a spanner wrench with two studs that fit into two of the holes to remove the arbor nut. Some have an arbor nut with a hex fitting, like a regular nut & bot setup, that the arbor wrench fits on. If you don't have the proper wrench sometimes you can get the arbor nut off with a pair of vice grips or pliers. You will want to turn the nut in the same direction as the blade spins when the grinder is on to remove it. When you put the new blade on, get the arbor nut hand tight, it is self tightening and will get tighter as you use the grinder.

UNPLUG tool first, there is a spindle lock near the upper guard/gearcase that needs to be depressed and slowly turn the wheel till it locks, The blade bolt is standard thread. You can go to milwaukeetool.com and with your model number download an owners manual for this tool. Let me know if you need more assistance.

Replacing the blade is simple. look for the lock button on top of the unit and use a tool or spanner wrench to loosen the blade.
Good luck

1. Unplug the saw.
2. Locate the blade lock button used to lock the motor shaft when changing a blade. For your saw, this button is usually located on the left side of the blade guard somewhere around the motor housing.
3. Push the button while rotating the blade until the button engages and the blade will no longer turn.
4. Use the wrench that came with the saw (or another wrench) to loosen and remove the blade bolt. For your saw the bolt should have standard right hand threads which means you loosen the bolt by turning it counter clock-wise.
5. Remove the old blade and replace it with a new blade of the same mounting type. Some blades have a round through hole and some blades have a diamond through hole.
6. Re-install the blade bolt and tighten clock-wise while holding the blade lock button down.

There is a nut that you release from the middle of the grinder wheel, (grinder blade)
This nut is flat and has four holes in it.

You will see you are providing a spanner wrench to remove this nut. The wrenches' actual name is Lock Nut Wrench. It has a U shaped end with two pins sticking out. On on each side of the U shape.

The pins are inserted into the holes in the flat lock nut, located in the middle of the grinding wheel. The wrench is laid flat against the grinding wheel, with the two pins of the wrench going into any two holes of the nut.

At the top of the Makita grinder you will see a Black button. The button is pushed down to keep the grinding wheel from spinning. Holds the grinding wheel in place, as you turn the lock nut loose. When you release the button, a spring inside pushes the button back up out of the way.

As you view the Makita grinder, Release Button towards the Back, grinding wheel towards you, the nut is turned to the LEFT, to loosen. It is a Left threaded nut.

The grinding wheel spins to the Right. Using a left threaded nut insures that the nut will stay tight, due to the direction the grinding wheel spins.

Have you removed the old blade yet?

The blade lock my be broken off -- it should be a button on top of the motor.

This saw has left hand threads -- turn clockwise to loosen the bolt/nut.

If you can't find the blade lock, lower the saw onto a piece of wood llike a 2x4 to keep the blade from turning.
