Collet
The bit flutes are sharp and
should be handled with
caution.
STANDARD COLLET
Push and hold down on the rotary tool shaft
lock button. Use a wrench to loosen collet nut
(counterclockwise) enough to insert a bit.
While holding down shaft lock button, tighten
collet (clockwise) to secure the bit. 1/8" of
shank should remain exposed above the col-
let.
DO NOT use collet in tools equipped with
3-jaw chuck.
CAUTION
KEYLESS CHUCK
Depress and hold the shaft-lock in, then rotate
the keyless chuck and shaft until the shaft-lock
engages and holds the shaft.
Rotate the keyless chuck counterclockwise.
Remove the old bit (if there is one) and insert
the new bit as far as possible, but not so far that
the bit flutes engage the jaws of the chuck.
Leave approximately 1/8" of shank exposed.
Re-engage shaft-lock and securely tighten the
keyless chuck clockwise by hand.
NOTE: When using 1/4" bits, it may be neces-
sary to use a wrench on the front of the key-
less chuck to securely tighten the bit.
