INSTALLING AND REMOVING
DRILL AND SCREWDRIVER
BITS
1.
CAUTION:
Always set reversing
button to center (locked OFF)
position when installing and
removing bits.
2.
The three-jaw chuck is designed
for self-centering of the bit. Open
jaws large enough by turning outer
sleeve (A) Fig. 2, counterclockwise,
when viewing the chuck from the bit
end, so that bit shank can be inserted easily.
3.
Clean and insert smooth end of bit as far as it will go into the chuck, or
up to the flutes for small bits.
4.
While holding the bit with one hand, turn outer sleeve (A) Fig. 2, clockwise
until the bit is gripped in the chuck.
5.
Tighten chuck by holding chuck ring (B) Fig. 2, with one hand while
turning outer sleeve (A) clockwise with other hand. Tighten securely.
WARNING:
Do not operate drill motor while installing or removing
bits. Operating drill motor can cause bit to be thrown from chuck
causing personal injury.
6.
To remove bit, reverse foregoing procedure.

ADJUSTING TORQUE
COLLAR
The clutch unit provides twenty-three
clutch settings plus a “Drill” (solid-
lockup) setting. Lowest torque is
available at setting #1, with maximum
torque available at the “Drill” setting.
The amount of output torque may be
adjusted by rotating the front collar
(A) Fig. 3, so that the desired torque
setting is aligned with the index mark
Fig. 3
(B) Fig. 3. In general, lower torque settings are used for driving small screws and
other delicate work, while higher torque settings are used for driving larger
screws. The “Drill” position is used for drilling and for driving very large screws.
TWO-SPEED GEAR SHIFT
The Model CL120 Cordless Drill/
Driver has a two-speed gear shift
which provides spindle speed
ranges as shown in Fig. 3A. To
change speed ranges: release
trigger switch to stop motor and
then slide speed selector (A) Fig. 4,
toward rear for HIGH speed or
toward front for LOW speed.
The low speed position is normally
used when drilling larger holes and
when driving or removing screws.
The high speed position is normally
used for drilling small holes.
