Solid performer with a few flaws

Solidly performing saw that copes with most jobs, including ripping of 2x treated framing material. Nicely compact and very well balanced making it easy to handle (with that fantastic DeWalt XR grip!). Gets up to speed quickly and stops even faster making it a safer tool to chuck about when working quickly. Depth adjustment is good, as is the bevel but be sure to check you're back at 90 as the 'coiled' pins can bind a little. Also check that the bevel adjustment screw is set correctly before first use as mine wasn't. Obvious limitations are the useless dust extraction (don't bother fitting the chute as it only works loose and doesn't do anything), sizeable gap at the blade-guard mouth and lack of a light to help sight your cut line. The supplied Dewalt blade is surprisingly good for rough framing and general outdoor work, which is really this saw's natural habitat. Sure it would perform well in a workshop too with a finer blade fitted. A really solid little saw and well worth the money if you're okay with the (relatively minor) niggles.

Lightweight and accurate

Generally a good quality lightweight saw which produces a very clean cut. A few niggles though, I agree with Ian about the saw guards, could be improved. Beware when using first time the blade on mine soon worked loose, easily tightened, but perhaps should have been checked before use. Batteries are relatively cheap if you buy the low amp hour ones so would generally recommend this saw.

A Good Saw

Had this saw for two years used every day of the week it is very accurate and with a good blade will cut 6x2 down we don't use the mains ones that we've got now and it's more powerful than the Makita 18-volt that we tend not to use. I'm very pleased with this saw

Good saw let down by design flaws

On the plus side, this is a good and accurate saw which is powerful, light and easy to use. The magnesium shoe is rigid and does not allow the blade to deviate at all from the set bevel even at the rear where this can be a problem in some saws. The blade brake is very efficient, stopping almost as soon as the switch is released. Fitted with a 52-tooth blade this saw produced lovely straight clean cuts in 18mm ply, a joy to use.

There are however some rather alarming negatives. The blade guard is rather flimsy-feeling plastic which doesn't feel especially safe and does not completely cover the lower part of the blade when fully deployed. You can see from the photo of the saw above that there is also a large gap between the shoe and the upper blade guard (saw body); this means that most of the sawdust and chippings are ejected at high speed out of the front of the saw, especially with the blade set for a shallow cut -- if you are using the saw two-handed then the hand holding the front handle will be shotblasted with high speed sawdust. Adding insult to potential injury is the included plastic "dust port" which attaches to the rear of the saw, snug up against the handle and battery: it's completely ineffective, even if you manage to get a vacuum hose attached (the handle and battery are in the way!) most of the sawdust flies out of the other end of the saw and the dust port's aperture is so small it would be a wonder if it ever managed to collect anything. These are not quality issues - the saw itself is extremely well-made as you would expect from a respected manufacturer - they are design faults, and really ought to have been ironed out during product development.
