It is possible that the motor is running backward but... first see the manual here:
http://www.plumbersurplus.com/pdf/08364.pdf Make sure the blade is installed as pictured in figure 4 page 11 of the manual.
After seeing the manual..... make sure the battery is charged correctly. The flat side of the battery should be toward the back of the charger when charging. If somehow the battery was inserted backward in the charger it is possible the battery was reverse charged during the intital charge. If you suspect this has happened.... insert the battery in the saw and run the saw until the battery is DEAD. Then insert it properly in the charger and leave it there for 9 hours so the charger will do the automatic tune up equalization of the battery.

If none of the above correct the problem, someone connected the internal battery power wiring incorrectly during FACTORY assembly. I would take it back to the retailer first... before processing a warranty claim.

I have dewalt 18 v circular saw i cut vinyl lattice once and used it on a 2x4 but it wouldnt cut it, started to cut then just stopped. is blade dull already? new saw.


a couple things to look at. Did the saw stop operating or was the blade not wanting to cut. Remove the battery and CAREFULLY feel the blade for dull or broken segments. If the blalde stopped check to make sure not a loose bolt holding it on. Did you reverse the blade for cutting the vinyl. Let me know more information and I will try and help

Can't remove the old blade, which way do you turn the nut?


set the blade lock or use a pair of vise grips securely fastened to the blade and turn the bolts counter clockwise
