Before you attempt any of this I would recommend going to 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 just bought this saw and am not an expert, but I was worried about how the manual said to grease it every 2-6 months "depending on use" or after prolonged disuse. After pulling bits of info from a lot of web sites, here's my take:

A guy towards the bottom of this page:

DeWALT DW304P Parts List and Diagram Type 1 eReplacementParts com

who sounds like he's worked on a bunch of these saws says that unless you feel the area under the black grip is getting hotter than usual, don't worry too much about greasing it. I may heed that advice since I don't plan to use this saw a lot, and if it takes a little damage from overheating before I add grease it probably won't be enough to kill the tool through continued infrequent usage.

However, if you use the saw a lot, then waiting till it feels too hot may mean you've done some damage and it could break down sooner than if you'd done regular maintenance as the manual suggests.

If you see grease/oil under the tool after storing it, have it serviced because a seal has likely broken or possibly heat caused the grease to separate or liquify enough to flow out of the gear box.

I couldn't find anyone describing how to grease the DW304P but I found this thread about greasing a similar saw:


Basically, you want to remove the guard around the blade holder, remove some screws that hold the black plastic grip on, and pull the whole black plastic grip off. Then there should be two round black covers that can be removed. You should see holes with grease under them. This is where to inject the grease. Unfortunately the guide isn't clear about exactly how much to inject, so you'll have to use your best judgement. Note that I have NOT taken my saw apart to verify any of this.

DeWalt seems to only sell grease in 4 pound cans with a part number 429698-00 at $67 or more per can. According to this thread:

What grade of grease should use in my tool DeWalt FAQ

Beacon EP 1 sounds like a compatible grease, but the author warns that you should clean out all the old grease in case the new grase is using an incompatible thickener. Opening up the gear box to clean out the grease would require ordering a replacement gasket from It's up to you if you want to risk just adding more grease through the greasing holes. Assuming Beacon EP 1 is truly compatible, if you can't find it (I'm having trouble finding it), this site lists technical info about Beacon EP 1 and lists theoretically compatible greases along the right side:


If you plan to inject grease into the holes without opening the gear box, make sure you also buy a grease gun or perhaps a large syringe.

Coord is fine tried many differant outlets, bu as soon as i plug it in the circuit braker trips.Any help about where the short is?

65 AMPS? That's drawing a LOT of power.
Is it tripping the breaker even before you pull the trigger?
If yes, I would use a continuity meter to start checking the various components. In particular, see if the switch is stuck in the ON position.
Unless you are experienced in tracking and performing electrical maintenance problem solving, this may be a situation best left to a repair shop.

That sounds dangerous! Does it actually cut after you do that? It sounds like it has bad gears and wouldn't cut if you put pressure to the blade. On a dw303 it's likely not worth repair if that's the case.

How do i intall a blade on a DW303 Reciprocating saw?

To install blade into saw:
1. Loosen set screw.
2. Insert blade shank from the front between the reciprocating shaft and the blade clamp.
Locate hole in blade over pin on reciprocating shaft.
3. Tighten set screw. If the blade should break off and the shank does not come out of the clamp,
be sure the set screw is loose and eject the shank with a nail or pointed object.

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, 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.
