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.

CHANGING THE COLLET

The bit flutes are sharp and

should be handled with
caution.
The 3.2mm collet is used with 3.2mm
diameter bits, the 6.4mm collet is used with
6.4mm diameter bits and the 4mm collet is
used with 4mm 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

INSTALLING BITS

The bits are held by a collet system. Use either
the 3.2mm, 4mm or 6.4mm 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.
Assembly
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 make sure that the
entire guide point tip will extend 2mm beyond
the material thickness (Fig. 2). For standard
point drywall bits, make sure that the fluted
end of the bit extends 2mm beyond the
material thickness.
THUMB SCREW
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).
