ADJUSTING DEPTH OF CUT
DISCONNECT TOOL FROM POWER SOURCE.
1. Open the clamp (A) Fig.
3.
2. Hold the base (E) and
turn the power unit (F)
Fig. 3 COUNTER-CLOCK-
WISE until the tip of the
bit is above the bottom
of the base.
3. Set the tool on a flat
surface.
4. Turn the power unit (F) Fig. 3 CLOCKWISE until bit touches the work.
5. Close the clamp (A) Fig. 3.
6. Rotate the depth adjusting ring (B) Fig. 3 until the zero-line (C) is
opposite the index line (D) on the housing.
7. Open the clamp (A) Fig. 3.
8. Tip the router so that the bit is clear of the work surface. Turn the power
unit (F) Fig. 3 CLOCKWISE until the index line (D) on the motor housing
reaches the desired depth indicated on the ring.
9. Close the clamp (A) Fig. 3.
NOTE: Setting the index line to 1/4" on the ring means the cutting edge of
the bit is exposed 1/4" below the base.
ADJUSTING SUB-BASE ALIGNMENT (All Routers)
Applications using a templet guide require the bit to be centered in the guide
This, in turn, requires the center hole in the sub-base to be in line with the
collet of the motor unit. Your model has an adjustable sub-base which has
been aligned at the factory. If the sub-base has been removed and/or
readjustment is required, use the following procedure:
Be sure power switch is in “OFF” position and tool is
disconnected from power source to avoid accidental
starting of motor which could result in injury.
1. Loosen the sub-base mount-
ing screws (C) Fig. 4 just
enough to allow the sub-base
(D) to move.
2. Open the clamp (A) Fig. 4, and
adjust the power unit so that
the collet nut (B) engages the
center hole in the sub-base (D).
Allow the sub-base to center
itself on the collet nut. Close
the clamp (A).
3. Tighten the sub-base mount-
ing screws (C) Fig. 4 securely.
