Spanner wrench provided with the router
New router bit
As the name indicates, a router is a power tool that routes out patterns in wood. The tool consists of a motor that drives a cutting bit; the bit spins quickly and cuts the wood. The router can be moved horizontally through the wood to form a desired shape, and the type of edge on the shape is determined by the design of the router bit. Different edge designs can be cut by changing bits. It is very easy to change the bit on a Black & Decker router.
Turn the router off and ensure that it is disconnected from the power supply. Wait for the router bit to cool down if it was recently used.
Detach the chip shield from the back of the face plate.
Depress the spindle lock button on the side of the router and rotate the spindle until it locks.
Turn the router upside down and place it on a flat surface.
Keep the spindle lock button depressed and loosen the collet nut that holds the bit with the spanner wrench. The collet is the device on the router that holds the bit in place.
Remove the bit and insert the shank of the new bit into the collet. The shank should protrude at least 1/8" from the collet.
Keep the spindle lock button depressed and tighten the collet nut with the wrench.
Release the spindle lock button. Reattach the chip shield.
