TOOL WORKS But, Within 15 minutes of chiseling concrete, oil started DRIPPING from the SDS chuck down the chisel shaft. Anyone else seeing this?

As long as the grease drips is nothing to worry about. This kind of hammer drill is always a little bit dirty. When the drill bit comes out clean and dry, you have to lubricate the hammer drill. Normally you have to bring it to a De Walt service center for maintenance.

No. It may have got a little warm but that would be the extent. 15 minutes of continuous chiseling might be a little too much for this tool. If you have that much to chisel I would recommend a commercial or industrial type of rotary/hammer drill. It may cost a little more but you will find that it will hold up better. This tool is perfect for light to medium work and not for continuous work.

No. I have drilled numerous 1/2" holes through 40+ year old concrete and chiseled the same concrete without any leakage of oil. This tool has been working great.

The shaft of the chisel needs to be greased as it moves in and out a small amount during the chiseling action. With use, this grease becomes liquified (grease is oil mixed with soap) and runs down the shaft of the chisel. If it is only a small amount, this is the reason and it can be ignored (but grease the chisel shaft regularly when in use).

Have only used the drill for drilling into brick & mortar and it has worked perfectly. Haven't tried chiseling concrete yet.

Nope, maybe it's just excess lubricant from the insides of the drill. I used my drill for a month of day to day use. It served my needs when I had to fasten two Quonset Huts down with anchor bolts and cap it with end walls.

No, They are designed specifically for SDS Plus type rotary hammer drills, not standard drills/hammer drills. They're built to slide up and down, and are not round where the a regular chuck would clamp them. If you need to drill into concrete, though, an SDS type drill and bits is the best way to go. It's night and day in the difference between using a regular drill with a hammer function and a rotary hammer drill and bit. Rotary hammer drills and bits cut like butter...at least my Bosch does. The bits last far longer and it cuts my labor time tremendously.

I use standard generic chain saw oil with no problem and I have never drained it out. I have never had any oil dripping as a result. Love my Makita!

Actually I did do that when cutting slabs of cement for a wall. The tool performed just fine. I just didn't like the thickness of the blade and considered it a waste of my time so went back to the thinner masonry blades, not to mention what a waste of money on the diamond blade. Perhaps you found a different blade than what was available here.

I haven't had any trouble with my not oiling right. I wonder - could the blade be to tight, it needs about 1/4 3/8th in play..

Not that I know of.. I have mot had this issue. What kind of oil are you using... if to thin try a thicker one if possible. This little saw has been great

How long did you let concrete dry before putting down sealer? I would apply another coat, was the sealer new? I had a similar issue with old product.

This happened to me as well. I didn't disassemble and clean right away after previous batch and the trace amounts of flour mixture seemed to cure and settle around the blade area. Soaking, wiggling, rotating, oiling were no match for the super-glue strong bond. The blade would not come off. Embarrassed I approached my other half. Like a superhero he took my loaf pan into his garage, pulled out a rather formidable looking crowbar . . . I couldn't watch . . .soon he returned with my loaf pan in one hand and the blade in the other.

I would contact manufacturer and explain problem. I have done this several times over the years with different itemsand often times a replacement is sent. Hope it works this time for you as this is a very handy tool!!!

Charlie - I am having the exact same problem with my brand new Makita UC3530A. Unfortunately, I found that many others were encountering similar problems with the saw not channeling the oil to the chain only after I had already purchased mine. I called Makita corporate customer service about the problem, and they suggested that I take it to a Makita service center. I am planning to take it to the Makita service center in Houston next week. The Makita rep at corporate HQ said that I evidently have a defective unit. I don't think so. I think this is a basic design defect with this saw because so many others are having a similar problem. I will see what the Makita service center folks have to say, and if I am not satisfied that this is a fixable problem I am going to return it to Amazon and buy something else. I regret that I might have to do so because the saw cut beautifully until I unknowingly dulled the chain to such an extent that it no longer cuts at all. The reason the blade dulled so quickly, of course, was that it was getting no oil to the chain, but I didn't realize that until the damage was already done. I hope this is of some help even though it certainly isn't a solution.

I use AMSOIL bar and chain oil. It does tend to leak out a little if stored with the oil in the saw. It is a great little saw!

I don't know the answer to that but I strongly recommended in past against purchase of this tool. The oil supply channel does plug readily and is not possible to keep clean. Because of this, the saw "eats" chains. Makita has not acknowledged or fixed this problem. See other comments on this issue. I have gone back to using my gas driven saw - easy to keep oil flowing with routine cleaning for optimum chain protection.

Mine was new. Just be sure that you have 90 psi operating pressure at the tool or the performance will be decreased, as I discovered. Not the tool's fault. See my review for more details.

We had the same problem with this one. Took it in to the local DeWalt dealer 6 months ago who replaced the chuck with a different style one. Haven't had any problems with it since.

I have not had that problem; I do not recall having to install the chuck on the shaft initially. Tony's response seems logical.

Sorry to hear that. I have done over 300 hundred 243 rounds and about the 50 of 30-06 and it is still going. I think you got one that was bad from factory.I would call or write Frankford Arsenal. I use my concrete garage floor to strike the tool. Wood is to soft. If you have a anvil, this is great. Good Luck

I have not had any problems with the gun. First of all, is it turned up too high where it is actually driving the nail all the way through the wood? You may want to practice on a two by four to test the depth setting. Second of all, and this is probably a stupid question but you do have the correct brad nails in, right? I have not had any problems with mine - it worked wonderfully for me. Sorry, I wasn't any more help.
