20 Most Recent Dewalt DW8306 36-Grit. 4-1/2" Blue Zirconia 7/8" Arbor Resin Fiber Disc Questions & Answers

Since tiles are so thick, brittle, and made of ceramic, a special saw must be used. An ordinary circular saw for wood or metal would either break the tile or get so hot that it would seize up and stop cutting. However, ceramic tile is not cut well with sharp blades. The wet tile saw was invented to address all these unique properties of ceramic. It doesn't overheat, uses a relatively dull blade with no serrations, and can be transported to a job site and set up on top of an existing table or sawhorses.

Full strip down, clean and lubricate. Don'y use WD40! Replace motor brushes.

Sand is exceedingly abrasive to moving parts. But you know that :>)

Considering the average domestic quality power drill has a design life of about 10 hours your saw probably isn't doing too badly.

I don't have a wiring diagram but the series-wound brush type motor hardly varies regardless of it's application. These motors are electrically very noisy and a high powered version is perpetually almost at the point of self destruction and so to prevent radio frequency interference they have to be heavily suppressed and suppression also helps protect the motor from itself.
Some manufacturers use discrete components for this purpose but some use a single component that is a network of capacitors and inductors, that necessarily is compact and therefore highly stressed and these do fail sometimes.

As a saw doesn't usually have a speed control, all the components can be checked for continuity with a multimeter unless it is fitted with a soft start, the testing of which is beyond the scope of home testing. If everything else is found to be ok the problem is likely with the soft start (if fitted).
The current usually flows through a series wound motor from the switch to a field coil, through the field coil to an armature brush, through the armature to the other brush and then through the other field coil to the neutral. There can be slight variations to this but basically the armature is in series with the field coils.

If you have power to everywhere except the brushes it would suggest a break in a field coil which is very unusual...
No power to the brushes would mean no power to one of the field coils which would mean you don't have power everywhere.

I suggest you begin dismantling and testing again...

any multi fit blade
it is only the shank width that may be a problem as some are too wide to fit in the slot

I think if DeWalt had included a reset button it would be quite obvious to the user, labelled as such and mentioned in the user manual...

You have to register to read the information (BAD, Dewalt. Bad dog.)

In general>
Check outlet, try another AC outlet.
Check power cord end to end for damage. Do you have a non-contact AC indicator? (You should) Are you getting AC to the machine?
Check built in fuse or breaker on the tool.
Check the switch, does it feel and sound like it is switching correctly? Or is something different?

if the plug on the cord fits any other outlet in the house it will be single phase
if the cord is cut , then it will have only 3 wires if it is single phase
( active , neutral and ground )
if it has 4 or more wires it will be 3 phase
most saws running a 200 mm blade or around that size and used for home duty will be single phase
the phase notation will be on the plate attached to the motor of the saw
It will read voltage , amperage, watts or hp, phase and cycles

if you are using thin cutting disk turn arbor nut over. It he shaft is rotating while tightening disc, use shaft lock button on side of gear box.

I think that I have the same model, and yes, I do find the buttons to be of some trouble. In my experience, they can stick, not allowing the leg to collapse. I have to keep them pushed in at the same time collapsing the leg. Look for any burrs or bending on the folding device itself, as it may have gotten bent during a move and needs straightened.
