To avoid injury and/or damage to finished work, always allow motor to come to a COMPLETE STOP before putting the tool down.

SOFT START

The Model 690LRVS has a “Soft Start” feature designed to minimize startup reaction torque.

VARIABLE STARTING SPEED CONTROL (690LRVS)

This router is equipped with a variable speed control (A) Fig. 23 with an infinite number of speeds between 10,000 and 27,000 RPM.

The speed is adjusted by turning the speed control knob (A), labeled 1 through 4, with 1 being the slowest speed and 4 being the highest.

USING THE TOOL

IMPORTANT: Before using the tool, consider the kind and total amount of material to be removed. More than one cut may be necessary to avoid overloading the power unit. Before beginning the cut on the actual workpiece, make a sample cut on a piece of scrap lumber. This will allow you to see the finished cut and to check dimensions.

Always be sure the work is rigidly clamped or otherwise secured before making a cut.

Generally speaking, when working on a bench, the workpiece should be held on the bench by wood clamps. When routing edges, hold the router firmly down and against the work with both guiding knobs.

Since the cutter rotates clockwise (when viewing router from top), the router should be moved from left to right as you stand facing the work. When working on the inside of a templet, move the router in a clockwise direction.

When working on the outside of a templet, move the router in a counter- clockwise direction.

Avoid “Climb-Cutting” (cutting in direction opposite that shown in Fig. 24). “Climb-Cutting” increases the chance for loss of control resulting in possible injury. When “Climb- Cutting” is required (backing around a corner), exercise extreme caution to maintain control of router.

The speed and depth of cut will depend largely on the workpiece. Keep the cutting pressure constant but do not crowd the router so the motor speed slows excessively. On exceptionally hard woods or problem materials, more than one pass at various settings may be necessary to get the desired depth of cut.

690LRVS, 691 specifications

The Porter-Cable 691 and 690LRVS routers represent a significant step forward in woodworking tools, combining power, precision, and user-friendly features. Designed for DIY enthusiasts and professional woodworkers alike, these routers are steadfast companions for a variety of routing tasks.

One of the defining characteristics of the Porter-Cable 691 is its robust motor. The router is equipped with a powerful 1.75-horsepower motor that delivers consistent performance, making it ideal for both heavy-duty applications and intricate detail work. With variable speed control ranging from 8,000 to 27,000 RPM, users can easily adjust the speed according to the material being routed, ensuring optimal results and minimizing the risk of damaging the workpiece.

The Porter-Cable 690LRVS model is recognized for its precision. It features a durable aluminum base that provides stability and allows for precise depth adjustments. The easy-to-use depth adjustment system employs a clear scale, enabling woodworkers to make accurate depth settings quickly. This means that intricate designs and patterns can be created without the worry of uneven cuts.

In addition to its performance capabilities, safety is a top priority for Porter-Cable. The design incorporates a soft-start feature which reduces the torque on startup, helping to maintain control during operation. This is particularly beneficial when handling large bits or working with hard materials, ensuring both safety and confidence for the user.

Another key feature of the Porter-Cable 691 and 690LRVS routers is their compatibility with various accessories. This versatility allows users to expand their capabilities, from edge profiling to mortising and everything in between. The industry-standard 1/4-inch and 1/2-inch collets ensure that a wide range of router bits can be utilized, adding to their utility.

The ergonomic design of these routers further enhances their appeal. The handles are designed for comfort and control, allowing for prolonged use without fatigue. Additionally, the compact size of the routers makes them easy to maneuver, ideal for both larger projects and detailed work.

In conclusion, the Porter-Cable 691 and 690LRVS routers exemplify a perfect blend of power, precision, and safety features. They are designed for woodworkers who demand reliable performance, making them an essential addition to any workshop, whether for simple home projects or professional furniture crafting. With their advanced technologies and user-centric design, these routers stand out as a top choice in the woodworking community.
