INSTALLING ACCESSORY BIT WHEN USING
THE COLLET NUT SYSTEM
1. Turn the switch to the OFF position, and
disconnect the plug from the power source.
2. Depress the spindle lock button (1), and
slowly turn the collet nut (2) until the spindle
lock button locks the spindle in place (Fig. 3).
3. Hold the spindle lock button down, and turn
the collet nut counter clockwise until the collet
is loose inside the collet nut.
4. Insert the shank of the accessory (3) into
collet at least 3/4”.
NOTE: Verify that the proper collet is used
for the accessory. If the collet is too large,
replace it with the next smaller size.
5. Press the spindle lock button, and engage it
in the spindle. While holding the spindle lock
button down, turn the collet nut clockwise by
hand to tighten it.
NOTE: Do not use pliers to tighten the collet
nut. Use the collet wrench (4) that is provided
with the tool. Over-tightening the collet will
damage the tool.
6. Pull on the accessory to verify that it is held
securely in position.
CONNECTING THE FLEXIBLE SHAFT TO
THE TOOL
WARNING: Do not bend the flexible shaft
to a radius of less than 6” (15.2 cm) when using
it with the rotary tool. Store the flexible shaft
carefully when it is not in use, avoiding sharp
bends.
1. Lock the spindle using the spindle lock button
(1) open the 3-jaw chuck (2) as shown in
Fig. 1.
2. Insert the drive shaft (3) into the 3-jaw
chuck as far as it will go.
3. Tighten the 3-jaw chuck onto the drive
shaft as shown in Fig. 1.
NOTES:
a) Do not overtighten the 3-jaw chuck
b) The flex shaft can also be attached to
the tool using a 1/8" collet and collet nut.
Install the collet and collet nut as shown in
Fig. 2.
CHANGING THE COLLET AND
ACCESSORIES IN THE FLEXIBLE SHAFT
To change the collet or to install an accessory
bit in the flexible shaft, refer to the steps listed in
the sections entitled “Removing the 3-jaw chuck
and installing a collet” (Fig. 2) and “Installing
accessory bit when using the collet system”
(Fig. 3).
NOTE: You cannot use the 3-jaw chuck with the
flexible shaft.
To lock the shaft in place while loosening or
tightening the collet nut, press the spindle
locking button (1) and rotate the collet nut until
the locking button locks the shaft (Fig. 5). Use
the collet wrench to loosen or tighten the collet
nut.
NOTES:
a) Do not attempt to loosen or tighten the collet
without locking the shaft as described above.
Doing so will damage the flexible shaft.
b) Do not over-tighten the collet nut.
