Good Deal
As a beginner woodworker, this planer seems to work very well. The boards feed properly, cutting depth is easy to determine and adjust, and the finished material is quite smooth. Can't comment on "snipe" (?) as I am not familiar with this term, but I see no irregularities. Have only made about 20 cuts to 4"x16" boards so far, so have not dealt with blade changes, etc. So far so good!

Woodworking Experience:
Works beautifully. It's a keeper.

Some directions unclear.

Spraying some sort of oil down from spinning rollers and cutters onto internal table - this is slowly decreasing to very little at present. What do you think this is from?

Good for the average woodworker.
I have had this planer for about 5 years and have put a ton of boards through it. Mostly pine, but some hardwood too. Just ran about 300 feet of cedar through it. It's not super fast and is not an industrial model, but for the average woodworkers it will do all thats needed!

Woodworking Experience:
Nice solid plane
Plane was easy to set and ran well. Manual stop height for 3/4" was out of calibration and needed to be set. Like the idea of a carriage lock.

Woodworking Experience:
Purchased this and ran some white oak through it. I was amazed at how well it worked right out of the box. Within minutes it was up and running. The cut was much better than expected. Taking the white oak from 4/4 to 3/4 the finish was almost to the point of not needing sanding. I owned a cabinet shop for almost 30 years and typically we purchased lumber planed to size. For those odd pieces I used my $20,000 time savers wide belt sander. The finish on this was equal to the finish of the sander. I would purchase this again and would recommend it to anyone looking to use it for a home shop..

What horse Power ?
MotorsbyRon on Apr 17, 2015
BEST ANSWER: I could not find anything in the operator's manual for horse power on this thickness plane, so I contacted Dewalt and they just got back to me today. Theior answer was that they do not list horse power on these units, but the y gave me a formula to figure it out. It is, Amps (15) x Volts (120) /746 = Horsepower rating (2.41 hp). So as you can see the formula say the horse power is 2.41.
Can this be attached to a dust collec
tion system?
Neil D on Dec 3, 2015
BEST ANSWER: The Dewalt DW734 can be attached to either a duct collector with a 4" hose or to a shop vac with a 2-1/2" hose. The planer comes with a 4 by 2-1/2" adapter.
How do I adjust height below 3/4"?
jack w on May 1, 2017
BEST ANSWER: You need to adjust thr turret stop.

Turret Stop
Your planer is equipped with a
turret stop (M), shown in Figure 11,
for repetitive planing of pre-set
depths. Stops are set at 0", 1/4"
(6.4 mm), 1/2" ( 12.7 mm) and 3/4" (19.0 mm). Use the
0" setting when planing between 1/8" (3.2 mm) and 1/4"
(6.4 mm).
1. Be sure the carriage is set above 1-1/4" (31.8 mm)
before trying to set the turret stop.
2. Turn the turret stop until the desired measurement
shows (Fig. 11).
3. Unlock the head lock lever (Fig. 8). Turn the depth
adjustment crank, lowering the carriage by the desired
increments, until it contacts the turret stop.
NOTE: The 3/4" (19.0 mm) turret stop can be adjusted for
other planing thicknesses. Adjusting the 3/4" (19.0 mm)
turret stop does not affect the other turret stop settings.

The manual is available on the product page. This is from page 4 and there are diagrams to assist.
Does this require 220 V?
C W on May 23, 2016
BEST ANSWER: No, it runs on 120
I see that this planer has 1 review and rated at 3 stars. When I click on "reviews" no review comes up on my computer, only questions. With no review showing how are there only 3 stars showing and based on what? I cannot determine if I want to buy this planer or not like that.
Benjamin on Feb 21, 2016
BEST ANSWER: Benjamin,
This planer has per formed as advertised, meaning as I hoped it would, and has continued to do so. So I rate it with 5 stars.
Be sure to plane both surfaces of your wood work piece for best parallel, smooth finish.

Benjamin ,
This planer has performed as advertised, meaning as I hoped it would and has continued to do so. So I rate it with 5 stars.
Be sure to purchase wood of sufficient thickness so that both surfaces can be planed for parallel and smooth surfaces.
is there a video to watch for 1st time users?
Kathy H on Oct 15, 2018
BEST ANSWER: Yes, I seem to recall watching a youtube video couple of years ago...can't recall the specifics, but
I believe if you google "how to use DeWalt planer, several videos should pop up. Hope this helps...mine has been a joy to use...however, dust collection leaves something to be desired.
Will it plane too 1/2” ?
Butch on Jan 22, 2019
BEST ANSWER: When planing to 1/2” you should never attempt in one pass. I would take off 1/8” and run it through 4 times. Think of your plane as a sander. Take off a little bit at a time.
Is it possible to plane a board to 1/2 inch?
John T on Jul 29, 2018
BEST ANSWER: John, absolutely, in fact, you can plane down to 1/4 inch, but 3/8 is as far as I've gone. No problem...hope this helps. Go have fun!
