ATTACHING A SANDING DRUM
1. Loosen the small screw in the top of the sanding drum holder. This allows the rubber to slacken.
2. Slide the sanding drum onto the holder.
3. Secure the sanding drum in place by tightening the screw causing the rubber drum to bulge and grip the
drum. Do not over tighten.
FLEXIBLE SHAFT INSTALLATION:
1. Remove the Shaft Collar (3).
2. Hold the handle (11) of the flexible shaft in one hand and the fitting collar (12) of the flexible shaft in your
other hand.
3. Raise the handle (11) end of the flexible shaft and shake gently. This will assist the flexible shaft to
become detached from the outer shaft and protrude from the fitting collar. See Figure 1.
Loosen the collet nut (2) on your Rotary tool and insert the inner flexible shaft into the collet (1) and
tighten the collet nut (2) with the 2 in 1 wrench.
4. Hold the rotary tool in one hand and the flexible shaft fitting collar in the other and let the other end of the
flexible shaft hang down freely.
5. Gently shake the Rotary Tool and flexible shaft and screw the flexible shaft fitting collar (12) onto your
Rotary Tool. Gently shaking your Rotary Tool and shaft will assist the inner flexible shaft to locate correctly
in the handle (11) of the flexible shaft assembly.
6. Tighten the collet nut (2) fully using the spanner provided. Always ensure bits are tight before
commencing any work with your tool.
7. Tighten the flexible shaft fitting collar onto your Rotary tool but do not over tighten.
Your Flexible shaft is now ready for use.
It is recommended that you never bend the flexible shaft any smaller than 5 inches in
diameter (Fig. 2)
Bending the flexible shaft any tighter than 5 in. will cause the inner shaft to bind,
causing additional load on your tool. Additional load could cause the tool to overheat
and the motor to fail or burn out. Motor burnout caused by this action will not be
covered under warranty.
When attaching and tightening tools to the flexible shaft, insert the “L” shaped wrench
into the hole in the end to act as the spindle lock button would
on the tool itself. Use the spanner wrench to tighten as normal.
