Pocket Depth Adjustment
The router bit for cutting the pocket is inserted into the router collet at the factory for a distance
of 1
5
/

” from the tip of the bit to the collet. This setting cuts at an optimal depth of
approximately
3
/
8
” for material between
5
/
8
” and
7
/
8
” thickness.
To cut a shallower pocket (in ½” material for example):
ƒ Place a shim with a known thickness on the work top and place your work piece over it.
To cut a shallower pocket:
ƒ Remove the router motor as described in the section for “Tool Changes”.
ƒ Loosen the motor collet and slide the bit to the desired exposure. (If the bit does not
move easily, try gently tapping on the bit near the collet with a wrench.)
ƒ Secure the collet and reinstall the router motor.
For your convenience, a blank Bit Gauge (Figure 11) is included with your machine so that you
may scribe a mark to record the depth that is most suitable for your purposes. Refer to the “Pilot
Drill Depth Adjustment” for this procedure.
