Safety Rules for Flexible Driver(fig.18, 7)
Do not operate the flexible shaft with a sharp or multiple bends. Ensure that there are no sharp residual
bends or kinks in the Flexible Driver before the operation.
Over bending the shaft can generate excessive heat on the jacket or hand piece and may cause the
Flexible Driver to disengage from the tool.
The minimum recommended bend radius is 6”(fig 20).
Always hold the hand piece firmly in your hands during the start-up. The reaction torque of the motor,
as it accelerates to full speed, can cause the shaft to twist.
Not for use with router bits or other large diameters (1” or larger) bits. Large diameter bits can cause
kickback and loss of control when used with the Flexible Driver.
Do not remove end ferrule while tool is running. The cable will become loose from the jacket and will
uncontrollably whip or lash around.

Directions for use
With small milling cutters / grinding pins: Use a high speed.
With large milling cutters / grinding pins: Use a low speed.
Precision work / engraving: Hold the drive unit like a pen.
Rough work: Hold the drive unit like a hammer.
Tips
Exert only moderate pressure on the workpiece and allow it to be processed at uniform speed.
You will not finish your work sooner by exerting heavy pressure. On the contrary, heavy pressure will cause the
drive unit to slow down or stop and will overload the motor.
For your own safety, use a vise or screw clamp to secure small workpieces.
