I'm sure your talking about a NiCad battery. It will show full but once it has a little age it won't hold and deliver a full charge. Recycle the battery and buy a new one.

SOURCE: My 7 1/4 in Craftsman circular saw stops running.

Is there anything jammed between the blade and the body/guard of the saw?

SOURCE: B&D Corded Circular Saw - Arbor Does Not Move

This model is not equipped with a clutch so its possible that the gears are stripped, shaft broken. If the blade moves freely then this is probably the case. If blade does not move freely, check for any foreign objects between blade and blade housing. I hope this has helped if you have any further questions don't hesitate to ask. Please rate on the helpfulness of the answer. Good Luck and have a great weekend.

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.

My Makita DSS610 18v cordless circular saw stopped working mid cut. I changed the battery to another, fully charged, one but still nothing. Tried again next day, with both batteries, still nothing.


Hello Derek, it seems that your motor or motor brushes have failed please contact the manufacture about replacing the motor brushes.

How to change brushes on hitachi c18dl


The brushes on your saw motor (Hitachi part number 324-572) are not replaceable. That is to say, Hitachi does not sell them as a seperate part, they are built into/part of the motor.

18 volt circular saw got hot one time and now will only run like it is using a dead battery, but is fully charged.


sounds to me like your battery has a bad cell in it would still read fully charged because the cells that are good are charged but still not a full battery

Can something be done


More likely it is a battery issue.

Often users run the saw for a period AFTER the battery starts to go down. The result is reverse charging the weakest cell which then will no longer take a charge

Try a new fully charged battery and NEVER run the saw beyond the point where it starts to slow down due to battery charge.
