INSTALLING AND REMOVING THE BIT

Disconnect tool from power source.

1.Stand the router upside down on its motor cap (Fig. 8B).

2.Clean and insert the shank of the bit into the collet until the shank bottoms. Then back it out approximately 1/16".

3.Press the spindle lock button (A) Fig. 8B, and place a wrench on collet nut (Fig. 8B). Tighten firmly.

NOTE: See “Installing and Removing Bits Using Spindle Lock Actuator When Router is Table Mounted” on next page for more direction on using the spindle lock.

4.To remove the bit, reverse the procedure.

Do not allow the wrenches to contact the columns (A) Fig. 9. Columns could be damaged, restricting the plunge action.

Avoid possible damage to collet. Never tighten collet without a bit.

If you remove the springs from the posts (E) Fig. 11 to use the plunge base in a router table, remove the post plugs carefully. They are spring-loaded and should be removed only when the base housing is in the up position (Fig. 8B).
