2. Remove power unit from base unit as follows:
a. Loosen clamping knob (H) Fig. 1.
b. Grasp power unit (A) Fig. 1, and pull straight up and out of the base
unit (B) Fig. 1. This will also release the depth adjusting ring (F) Fig. 1,
from ring springs (G) Fig. 1.
3. Lay power unit on bench with collet toward you.
4. Clean and insert shank of bit into collet until end of shank bottoms. Then
pull out approximately
1
/16

5. Place one wrench on flats of shaft directly above collet nut (J) Fig. 1. Let
far end of wrench rest on bench to your RIGHT.
6. Place other wrench on collet nut (J) Fig. 1, and turn clockwise to tighten.
TIGHTEN SECURELY.
TO REMOVE THE BIT
NEVER TOUCH BIT IMMEDIATELY AFTER USE, AS IT
MAY BE EXTREMELY HOT.
1. Repeat Steps 1 through 3 under TO INSTALL BIT.
2. Place one wrench on flats of shaft directly above collet nut (J) Fig. 1. Let
far end of wrench rest on bench to your LEFT.
3. Place other wrench on collet nut and turn counterclockwise and loosen
only enough to allow removal of bit. NEVER TIGHTEN COLLET NUT
WITHOUT BIT IN COLLET. This may allow collet to deform and weaken
clamping ability.
ADJUSTING BIT EXPOSURE
1. DISCONNECT TOOL FROM POWER SOURCE.
2. With power unit removed from base unit, turn depth adjusting ring to
position ring approximately six threads from top of power unit.
3. Insert power unit into base unit, aligning one of the grooves in the motor
housing with the pin protruding from inner wall of the base. Proceed until ring
springs snap into groove in depth adjusting ring.
4. Viewing power unit from top, turn depth adjusting ring clockwise to
decrease depth of cut, or counterclockwise to increase depth of cut.
NOTE: For convenience in making slight adjustments, a marker can be found
on the base next to the ring spring. The depth adjusting ring is graduated
with eight equally spaced lines each representing
1
/64" change in depth of
cut, (when rotated in relation to the marker). One complete turn of the ring
changes the depth of cut
1
/8".
5. USING ONLY FINGER PRESSURE, TIGHTEN CLAMPING KNOB.
6. Make a practice cut on a piece of scrap material (see USING A
LAMINATE TRIMMER).
