Manual & Single Slope Mode

By pressing the Manual button on the control panel, this unit switches from Automatic Self-Leveling to Manual mode, indicated by flashing LED’s. This allows the Y-axis to be sloped up or down by the remote control. It also allows the X-axis to to be sloped, again with the remote control

Pressing the Manual button again puts the unit into Single Slope Mode, also indicated by a set of LED’s. This mode allows you to slope the Y-axis while the X-axis remains in self-leveling mode.

This versatility helps the LL300N be useful in a wider variety of applications.

Manufacturer Information

Spectra Precision has a solid reputation and has been making high grade construction instruments for over 55 years. This kit is covered by a 5 year manufacturer’s limited warranty.

They have an informative and helpful website. Their sales and support is available from their Contact Page, and by telephone.The Spectra LL300N User Guide can be viewed online and downloaded. They also have an informative cut sheet available for this piece.

Next is the Slope Mode button. When in slope mode, out of self-leveling mode, it automatically engages the X-axis, and the unit can be sloped. LED’s indicate the direction of the slope. The Y-axis can also be engaged, and the unit can switch between the X and Y axis.

This one has a couple different choices for the laser as well. The Speed button adjusts the laser beam through its 4 preset speeds. The Scan Mode button causes the laser beam to sweep back and forth, rather than rotating, to create a short, brighter line. Scan Mode has multiple angles of 15°, 45°, and 90°.

The Arrow buttons control the laser for clockwise or counter-clockwise rotation in horizontal or vertical mode. And they are also used to tilt the laser head when the unit is in Slope Mode.

Accessories In This Kit

Also included in this kit are a laser detector for increasing the range of the laser, and a detector bracket for attaching the detector to a grade rod. The kit also includes 1 20V MAX battery and the 20V battery charger.

You will get a ceiling bracket for mounting the laser unit to a wall, or other structure. There is also a pair of laser enhancement glasses, a taget card, and a 5/8″ tripod adapter. The entire kit fits into a rugged, hard shell storage case, which is a part of the kit as well.

How About The Battery?

In my opinion one of the best features about the DeWalt DW074LR is the batteries. This is the only laser level on the list with a rechargeable battery pack. You don’t have to keep buying D or C type batteries and have them around. Having batteries go dead, and not having any around can seriously put a kink into your work.

Plus there’s not the waste of throwing old, dead batteries away. This DeWalt unit comes with their 20V MAX battery charger. So just pop it back on the charger.

Which leads to another notable advantage:  you can purchase multiple batteries. So you can always have a fully-charged battery if the one in use gets low. Then just swap them out. That’s a big plus.

Plus, chances are that if you’re a big tool guy (or girl), you’ve most likely got some DeWalt tools already. Their 20V MAX system drives a lot of the different tools in their lineup.

One Of The Best Names

DeWalt has one of the most respected names in the world when it comes to power tools. They have been in business, and an innovation leader since 1924.

Their web site is helpful and informative. You can contact support directly as well as register your product for more features. The DW074LR Instruction Manual is viewable online and can be downloaded.

Their products are made in the USA, “with global materials.” They source raw materials and components from around the world when they are not available or viable due to cost in the USA.

This unit comes with a three year limited warranty from the manufacturer. Plus, 1 year of free service for worn parts caused by normal use. And it also has a 90 day money back guarantee.
