Dewalt DW936 Troubleshooting

This page helps identify common issues and problems with the Dewalt battery powered, circular saw.

Saw Does Not Turn On ¶ 

When I pull the trigger nothing happens.

Locked Up ¶ 

Make sure you have released the lock off button above the trigger before each use. Letting go of the trigger automatically activates the lock off button.

Battery Is Not Charged ¶ 

Plug in battery to charger. If light is blinking red leave in the charger; it needs to be charged. If the light is constant red it is fully charged. (For information on changing or charging the battery, see the Device Page.)

If neither of these apply, you may have a mechanical problem. You should contact DeWalt for maintenance or repairs.

Trigger Is Stuck ¶ 

I am trying to pull the trigger to start the saw but I cannot pull it down

or The trigger is stuck in the down position.

Check to make sure the that there is nothing attached to the trigger.

Make sure the lock off button above the trigger is not on. (Letting go of the trigger automatically activates the lock off button.)

If the trigger is still stuck, it may need to be replaced. (See Device Page for step-by-step instructions)

Circular saw is not working ¶ 

Saw Will Not Cut Deep Enough ¶ 

It's cutting through the top of the material, but not all the way though.

Make sure the saw is turned off, then loosen (screw counterclockwise) the depth adjustment knob (knob on opposite side from blade) and raise the flat metal bottom piece until one tooth of the blade extends under the piece you wish to cut. Then re-tighten the depth adjustment knob before turning the saw back on.

My Cuts Are On An Angle ¶ 

I am trying to get a normal cut, but the blade keeps making a sloped cut.

If you are trying to cut at a 90 degree angle but it keeps coming out as a more acute angle(>) turn off the machine, then try loosening the knob by the front of the saw blade. Once loose pull the flat metal leveling piece towards the trigger to make it perfectly level. Tighten knob to lock back into position.

My Saw Blade Wiggles ¶ 

To test if your blade is loose, turn off machine and remove battery pack. Try moving the blade back and forth with your fingers. If there is blade movement, it needs to be tightened.

To tighten the blade, screw the washers in the center of the blade clockwise using the blade wrench.

My Saw Is Not Cutting Easily ¶ 

A Crack In My Blade ¶ 

Change your blade immediately. (for information on changing the blade see the Device Page.)

Takes A Lot Of Force To Cut ¶ 

Your blade tips may be dull. To check to see that blade tips are sharp, turn off the saw, then see if they appear rounded. If they do, then it is time to change your blade. (for information on changing the blade see the Device Page.)

Saw Stops Moving Forward But Stays On ¶ 

I was sliding the saw forward and it stopped moving, but the saw blade keeps spinning.

Turn off the saw. Make sure there is nothing in the way of the plastic blade guard. To check this pull on the plastic lever in the back until it rotates all the way to the front of the saw.

Feels Like Over Heating Or See Smoke ¶ 

I was using the saw and noticed smoke coming out of the engine

Material Issue ¶ 

Turn off your machine. Make sure there is nothing hindering the saw movement. If you are cutting through more than is intended you could overwork the engine. Remove anything that is in the way of the blade. Do not use the saw until it has cooled off.

Blade Issue ¶ 

Make sure you are using the right saw blade for the material you are cutting. (For example, if you are cutting a metal make sure you have a blade intended for metal. In general, metal is cut with a stronger and finer toothed blade than wood.)

If neither of these apply, you may have a mechanical problem. You should contact DeWalt for maintenance or repairs.
