Introduction
This manual provides essential instructions for the safe and effective use of the DEWALT DNP612 Plunge Base for Compact Routers. The DNP612 is designed to enhance the versatility of your compact router by allowing for precise plunge cuts. It features an adjustable, tool-free steel motor cam lock that makes depth adjustment and base changes quick and solid-locking. Precision machined brass bushings and case-hardened steel guide rods ensure a smooth and accurate plunge stroke. The clear LEXAN sub-base offers enhanced durability and bit visibility, and it accepts standard template guide bushings. Ergonomic rubber overmolded handles and a low center of gravity design contribute to user comfort and control. The heavy-duty, die-cast aluminum base and motor housing provide durability while maintaining a low tool weight. A five-position adjustable turret stop aids in stepped or repeated plunge cuts, and micro-fine depth adjustment (5/128" per turn) allows for precise routing in veneer and inlays. An easy-to-reach plunge lever and switch offer superior control during routing operations.

- Gently depress the plunge lever to lower the router bit into the workpiece until it reaches the preset depth stop.
- Engage the plunge lock lever to maintain the depth during the cut, if desired.
- Guide the router smoothly along the desired path.
