REMOVE THE BLADE !!!! take the handle apart and lift out the switch. keep track of the lock slide button and how it is installed. unplug the switch wires. carefully touch the wires you just unplugged onto the battery terminals. these wires lead directly to the motor. BEWARE.. if the motor components are good , the saw will run at FULL SPEED. you only need to tap the wires, DO NOT jamb them onto the battery. If the motor runs then most likely the switch is bad. If you know how to use a continuity tester then you can also check the switch. Bad moter likely culprtet is the brushes are crapped out.

SOURCE: Reciprocating saw stops reciprocating

your missing a tooth on a large round gear in the gearbox.

when the gear on the engine rotates into the position where the little engine gear spins because there is no tooth to come into contact with the engine runs but the gearbox doesnt spin, hence no reciprocation, but engine runs.

if you bump the blade it will start going again, but when you cut it will stop offasionally in mid cut. you can repair this but stop using it the engine gear will be destroyed otherwise

I have a dewalt dw303 that you can use for parts, I need a new trigger or something the motor is dead and I found a new saw. go to craigslist.org, rochester ny tools section and look for dewalt dw303 that is my listing. for ten bucks ill sell you all the gears you need. i think it is close to the same model, i am sure it is the same gearbox.

try opening your gearbox, im positive that is what is wrong.

Before you attempt any of this I would recommend going to Dewaltservicenet.com and see what the inside of this tool looks like. It appears that you need to remove part of the front gearcase to get into the lube. The back e.g. brushes is not that big of a deal. If there is a Service Center near you they have a Max repair rate that they will fix anything on this saw at a preset firm price and if it is less that is what they would charge.

I would look at the battery contacts first for burnt/discolored contact, if so clean with something like a pencil eraser, look at the contacts on the tool also. If these are acceptable then I would think a loose wire inside the handle area is causing. Before disassembly hold tool level and GENTLY tap with a soft hammer to see if you can get it to work and that would be a first indication of a bad connection

Dewalt Model D304-04 reciprocating saw wont run. I plug it in, pull the trigger and it wont start. What am I doing wrong or what could the cause be?


Hi Fred:
Hmmmmm.
- Confirm there is power in the plug.
- use continuity meter to check that there is a complete circuit through the saw.
- broken connection in plug?
- broken wire between plug and switch?
- switch not functioning?
- switch set between forward and reverse?
- Speed control potentiometer contacts dirty?
- Bad brushes?

Won't run


These tools are well known for overheating and failure (breaking off) one of the prongs that the battery connects to. This is part of the switch so it would need a new switch if this is the case.

I have a Dewalt DC385 Reciprocating saw, when I hold it with the blade down or level the saw will not work but when I have the blade pointed upwards it works fine. I don't think it is the trigger...

Saw seems dead, after 8 - 12 trigger pulls the saws turns on (sometimes) but after you release trigger its dead again???


You should check the brushes and cord first but it sounds like your trigger is shot, not an uncommon failure for this tool. With the cord plugged in, hold the trigger on in one hand and bend the cord around in several placed, especially near the boot and push and pull it in the tool. If it comes on, replace the cord. If the it doesn't react to this, check the brushes. Without knowing which model you have, they should be at least 1/4" long, evenly worn and shiney, not burnt, where they touch the armature. If these check out you need a new switch.
