Black & Decker JS660 Troubleshooting
Released November 2008, identified by model number JS660.
Saw won't turn on ¶
The saw will not power up or show signs of life
The cord is not plugged in ¶
Make sure the cord is plugged into a working outlet. If the cord is cut or damaged then you can simply fix it by following our free guide here.
Tripped Breaker ¶
Each circuit has a breaker that lowers the risk of electric shock. From time to time the breakers will trigger and shut off a circuit. To reset the circuit, you have to find the breaker box and identify the breaker that popped. Normally you just need to find the one in the OFF position and switch it to the ON position.
Broken trigger ¶
If the saw is not responding at all, then the trigger could be broken. in that case you will have to take off the housing of the motor and use a multi-meter to check if the component is broken or not. a guide to testing and replacing your trigger can be found here.
Blown out motor ¶
The only way to see if the motor is blown out or broken is to use a multi-meter and check the electrical connection through it. you can follow our guide to replace it here.
Blade is loose or falling out ¶
The blade falls out of the saw and/or is loose causing cuts to not be straight
Broken Blade ¶
Check the blade itself to see if the tang (part that goes into the saw) is chipped, cracked, or broken off. If this is the case, the blade must be replaced.
Broken Blade Mount ¶
Check to see that the blade mount is not missing any hardware that would keep it functioning properly. If so, replace the hardware. If that is not the problem, the blade mount most likely needs replacing.
Smart Select Dial does not Change Speeds ¶
When changing the Smart Select dial to cut different materials, the blade speed does not change.
Broken Smart Select Dial ¶
First, check to make sure that the Smart Select dial feels firm and like it is engaged. If it isn't, make sure it is firmly in place. If it is firmly in place, the entire Smart Select dial probably needs replacing.
Shoe Plate is Loose or Vibrates ¶
The shoe plate is loose which causes it
Shoe Plate is Unlocked ¶
Check to see if the shoe plate bevel lever is pushed away from the saw.
Shoe Plate is Broken ¶
IF the shoe plate bevel lever is pushed away from the saw and the shoe plate still is loose, the shoe plate needs to be replaced.
