SELECTING THE BIT

Models 7538 and 7539 accommodate bits with 1/2" diameter shanks that install directly into the power unit collet. Collets are available that will allow the use of bits having 1/4" or 3/8" diameter shanks.

DO NOT USE router bits with a diameter in excess of 2-1/2", except when using Model 7539, set for either 10,000 or 13,000 RPM. Router bits with a diameter up to 3" may be used with the 7539 motor operating in the 10,000 or 13,000 RPM speeds.

While preparing the router for use, while making adjustments, and when router is not in use, ALWAYS

DISCONNECT IT FROM THE POWER SOURCE.

INSTALLING AND REMOVING THE BIT

Confirm that the power switch is in the “OFF” position and that the tool is disconnected from the power source to avoid accidental starting which could result in injury.

1.Place the router upside down on its motor cap (see Fig. 1).

2.Clean and insert the shank of the bit into the collet at least 3/4". If the shank “bottoms” in the router, back it out approximately 1/16" to allow for proper tightening.

3.Place one wrench on the flats on the chuck and one wrench on the collet nut (see Fig. 1). Tighten firmly.

4.To remove the bit, reverse the procedure. If the bit is difficult to remove easily, tap the collet nut with the wrench.
