IMPORTANT:
Follow the rules below when using your
flex shaft to prevent overheating the flex shaft and personal injuries.
•Lubricate your flex shaft regularly to prevent overheating (see page 13).
• Do not bend the flex shaft near its connection to the rotary tool. Keep
it straight.
• Never cross the flex shaft over itself during operation. Do not operate
the flex shaft with a sharp bend. The recommended minimum radius for
the flex shaft is 5 inches. Bending the shaft farther than this can generate
excessive heat and damage the flex shaft.
1. Unscrew and remove the locking collar from the end of
the rotary tool (Fig. 2).
2. Take the flex shaft and slide the inner core out about 2 to
3 inches (Fig. 3).
3. Loosen the collet nut on the rotary tool by pressing down
on the spindle lock button and unscrewing the collet nut
(Fig. 4). Use the 1/8 in. collet for attaching the flex shaft.
4. Insert the inner core of the flex shaft into the collet nut
and collet (Fig. 5). Make sure that the golden metal ring is
pressed tightly against the collet nut (Fig. 6). Press down on
the spindle lock button, and fully tighten the collet nut with
the included wrench.
5. Now that the inner core is secured to the collet nut, slide
down the flex shaft adapter and screw it in place onto the
rotary tool by turning it clockwise (Fig. 7).
6. Once secured, take the other end of the flex shaft. Find
the L-shaped tool and insert it into the hole on the side of
the flex shaft handle to prevent the flex shaft spindle from
rotating (Fig. 8).
7. Unscrew the shaft collet nut and check the size of the col-
let against your rotary bit. Always select the correct size of
collet for the operation (Fig. 9).
8. Install the collet and collet nut and fully insert the rotary
bit into the center hole through the collet (see page 10). Use
the included wrench to fully tighten the collet nut and ensure
that the bit is properly secured to the flex shaft (Fig. 10).
