desired depth indicated on the ring.
10. Tighten clamp screw (A), Fig. 3 firmly.

edge of the bit is exposed

ADJUSTING SUBBASE ALIGNMENT

Applications using a templet guide require the bit to be centered within the
guide. This, in turn, requires the center hole in the subbase to be in line with
the collet of the motor unit. Your model has an adjustable subbase which has
been aligned at the factory. If the subbase has been removed and/or
readjustment is required, proceed as follows:
CAUTION: 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 personal injury.
1. Loosen subbase mounting screws just enough to allow subbase to move
on base.
2. Loosen clamp screw (see Fig. 4), and adjust motor so that the collet nut
engages the center hole in the subbase. Allow the subbase to center itself on
the collet nut. Tighten clamp screw.
3. Tighten subbase mounting screws securely.
