Question about Makita Usa Inc 9557PB 4 1/2" Angle Grinder
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.

on a grinder the nut that holds the wheel on has left handed threads.....that means it has to be turned in the opposite direction than conventional nuts do..there should be a button on the casing to hold in..this keeps the grinding wheel from turning wheel being removed....remember to unplug first..thanks and have a great day
