1 Check the grinder before you
begin. The newer discs on rotary grinders have patented buttons that
allow you to remove the disc without any tools. You may have one like
that. In models like this, there's usually a spot to depress and then
remove the disc.
2 Turn off the grinder before you
attempt to remove and change the disc on your rotary grinder. If it's
battery powered, put the grinder in lock position so you can't
accidentally turn it on. If it's electric, unplug the grinder from the
wall.
3 Look for a nut in the center of
the disc. This is a give away that you need to use your special wrench.
Sometimes the grinder comes with a tool necessary to loosen and remove
the nut. Other times you need to use a wrench.
4 Lock the wheel into place before
you begin. You can find a button or switch at the side or back that
allows you to do that. When you lock the wheel in place, the disc
remains still as you loosen the nut in the center.
5 Remove the nut in the center
with either the tool provided with the grinder or a shop tool and lift
the disc off your rotary grinder.
6Lift the disc off the rotary
grinder. If you have different discs, remember to check for the best
fit. Put the nut back on a different way for different discs. Check for a
rim and indentation on one side of the nut and a flat side on the
other. A visual inspection of the disc for the rotary grinder gives you
information about the side to use.
Here is a diagram of your grinder and the tool you are looking for is number 50...
There usually is a locking pin that stops the
wheel from turning. MAKE SURE YOU HAVE
THIS UNIT UNPLUGGED!!! Press this button
in while slowly rotating the wheel, once it engages
the wheel will lock. With your wrench you can now
take off the blade. It may have a left handed thread
so going clockwise will loosen it.
The battery is likely to be fine, but what about the electric motor in the saw, in rice as well? The only thing that tends to get damaged is electronic board components.
Rice only works well if it was warmed first, silica gel packs are better. A couple of days should be good, but my advice it open it up straight away and dry with a hairdryer or heat gun.
It is likely that the trigger switch on your saw is faulty and not allowing power to flow to the motor. You may need to have the switch repaired or replaced by a professional. In the meantime, you may not be able to use your saw until the issue is resolved.
The cutterhead is now exposed. If the eight screws in
the cutterhead clamp are not visible, use a piece of
scrap wood to carefully rotate the cutterhead (Fig. S)
until the screws are accessible and the cutterhead lock
lever18engages. This will prevent further rotation of
the cutterhead as you change the knives
I can't even find a part number for this in Dewalt manuals much less the size of such. There are instructions for measuring belt sizes on the web but that's it. No use searching the Dewalt web site for the belt in the product listings. I tried and it defies any seach I can come up with. I gather they must have some internal inventory system that only they have access to. So, that looks like a job for "customer service" 800-433-9258 Monday - Friday, 8:00A.M. - 6:00P.M. Or you can try their email form on their webpage. As I can't even come up with a parts number for the belt I'm a little shy to refer you to some replacement parts dealer whose product quality I would have no way of knowing even if I had the belt size --which I don't. It is not easy to even pull up specifications for the saw you designated and those don't list belt sizes. You would think it was a nuclear secret.
