4.Position the depth indicator (H) Fig. 3 at the “O” position and tighten the knob.

5.Loosen the depth rod locking knob (K) Fig. 3, and raise the depth rod until the indicator aligns with the graduation representing the desired depth of plunge (The example in Fig. 5 shows setting for 1" plunge.) Tighten the depth rod locking knob.

6.To limit the upward travel of the plunge mechanism: (1) release the plunge lock by moving the plunge locking lever (C) Fig. 2 to the left, and move the motor to the desired maximum height; (2) release and push the locking lever to the right to secure the motor in this position; (3) use two 9/16" open-end wrenches (not furnished) to move the travel-limiting nuts (O) Fig. 6 against the top of the motor housing boss (T) Fig. 6. “Jam” the nuts together to lock.

Set the travel limiting nuts so that bit can be retracted into base of router, clear of work.

“Jam” the travel limiting nuts together to prevent movement (caused by vibration) which could prevent full bit retraction.

DO NOT attempt to increase plunge travel by readjusting the stop nut (P) Fig. 6. Increasing the travel beyond 3" can cause mechanism to jam.
