How to Remove a Plunge Router Spring

Plunge routers are woodworking power tools that allow you to move the bit up or down to adjust the depth of the cut. Spring-loaded columns aid the bit in moving up and down. Unfortunately, the strength of these springs can make it very difficult to adjust the router. Some people prefer to remove the springs so that adjusting the router bit requires less effort. Removing the springs from a plunge router is a simple task that takes just minutes.

Things You'll Need

• Adjustable wrench

Instructions

1. Unplug the plunge router from its power source. Lay the router on its back on a flat, stable surface such as a table or counter top. Engage the locking lever, knob or button.

2. Remove the locking nuts and washer at the top of the height rod. Set the removed pieces aside.

3. Move the plunge router to the edge of the table and press your body against the base. Disengage the locking lever, knob or button; you should feel the base of the router press back against you. Pull the base off of the router and set it aside.

4. Grasp the springs at the bottom of the router and slowly pull them from the router body. Bend the springs slightly toward the floor as you pull them out to engage the metal posts inside the springs. Set aside the removed springs and posts.

5. Place the base on the table or countertop. Thread the height rod through the router housing and reposition the router on the base. Replace the locking nuts and washer at the top of the height rod.

Tips & Warnings

• Some plunge routers have a small brass locking pin that may fall out when you remove the springs. Insert the brass pin into the small hole at the base of the columns before repositioning the router on its base.

• Never attempt to service the plunge router while it is plugged in; serious injury or death may result.
