Disconnect the plug from
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally. Make certain that the
collet nut is securely tightened before turning
the tool on.

INSTALLING BITS

The bits are held by a collet system. Use either
the 1/8" (.125"), 1/4" (.250") or 5/32" (.156")
collet depending on the size of the bit shank.
The bit flutes are sharp and
should be handled with
caution.
Depress and hold the shaft-lock in and rotate
the collet nut and shaft until the shaft-lock
engages and holds the shaft.
To prevent damage to tool.
Never use the shaft lock as a
braking devise to stop the tool from rotating.
Use the standard equipment wrench to
loosen nut (counter-clockwise) (Fig. 2).

Re-engage the shaft-lock and tighten the nut
(clockwise) by hand and then with the
wrench until bit is held securely.

CHANGING THE COLLET

The 1/8" collet is used with 1/8" diameter
bits, the 1/4" collet is used with 1/4" diameter
bits and the 5/32" collet is used with 5/32"
diameter bits. To change collets, first
remove the bit. Continue to loosen and
unscrew the collet nut until you can remove it
from the tool. Remove the collet and replace
it with the other (Fig. 3). (Each collet is
double-ended, and either end is acceptable
to use.) By hand, re-tighten the collet nut
around the collet in a clockwise direction.
You are now ready to insert a new bit as
instructed in Installing Bits (Fig. 2).
