G8749 Drum/Flap Sander
ON/OFF Switch
This machine has a special safety ON/OFF pad-
dle switch with a removable switch disabling key,
as shown in Figure 14.
Turn the machine OFF, then remove the disabling
key when leaving the machine to prevent acciden-
tal or unauthorized start-up.
If the key is removed while the machine is run-
ning, the sander can still be turned OFF. However,
you need to re-install the key before turning the
sander back ON.
Drum Sanding
Drum sanding is perfect for performing sanding
operations on edge contours.
Use a soft sanding sleeve when sanding contours
with rounded or soft edges. A hard sleeve is desir-
able when the sanded edge is to be sharp.
Make sure the sanding sleeve is mounted on the
drum and sander so that the sleeve rotation and
spindle rotation match. The spindle will always
rotate toward the operator.

Flap Sanding
Figure 15 shows a typical drum sanding opera-
tion.
Flap sanding is useful for sanding rounded or
spherical shapes. With the flap sander mounted
on the left hand spindle, the abrasive side of the
sanding flaps will rotate toward the operator. It is
generally best to introduce the workpiece to the
bottom of the flap sander, as shown in Figure 16,
for the best control of the sanding forces.
