CHANGING THE COLLET

The bit flutes are sharp and

should be handled with

caution.
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, loosen the collet nut with

the included wrench and 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. 4).

-7-

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.

REMOVING, INSTALLING, AND

ADJUSTING THE DEPTH GUIDE

In order to remove the depth guide from the

tool, turn the thumb screw counter-clockwise

until you can remove it from the tool. The

depth guide should then pull freely from the tool.
To reattach the depth guide, line up the slot in

the depth guide with the threaded hole in the

metal housing and re-install the thumb screw

by rotating it clockwise until tight. Be careful

not to cross-thread the thumb screw.
The depth guide allows you to control the

depth of cut. Loosen the thumb screw by

turning it counter-clockwise until the depth

guide can slide freely on the metal housing.

For bits with a guide point (Drywall XBITS™,

Guidepoint

and Window & Door Zip

bits)

make sure that the entire guide point tip will

extend 1/8” beyond the material thickness

(Fig. 2). For standard point drywall Zip

bits,

make sure that the fluted end of the bit

extends 1/8” beyond the material thickness.

WARNING

INSTALLING BITS

The bits are held by a collet system. Use either

the 1/8", 1/4" or 5/32" collet depending on the

size of the bit shank.
Depress and hold the shaft-lock in and rotate

the collet nut and shaft until the shaft-lock

engages and holds the shaft.
Use the included wrench to loosen the nut by

rotating it counter-clockwise (Fig 4). Remove

the old bit (if there is one) and insert the new

bit as far as possible. Re-engage the shaft

lock and tighten the nut by rotating it

clockwise by hand, then with the wrench until

the bit is held securely.
