PNEUMATIC SANDING
DRUM FOR BUFFERS
INSTRUCTIONS
Figure 1. Model G1972.
Functional Overview
A pneumatic sanding drum mounted to a buffer
allows for easy and smooth sanding of contours
and curves.
The inflatable bladder provides for easy changes
of the replaceable sanding sleeve and also allows
for fine-tuning of the overall flexibility of the drum
for sanding compound curves and contoured sur-
faces.
By increasing the pressure in the drum, a user
can create a more rigid surface for sanding shal-
low contours. Similarly, by decreasing the pres-
sure, a user can soften the surface of the drum,
allowing it to "wrap-around" workpieces with
tighter curves.
Completely releasing the pressure decreases the
diameter of the drum so the sanding sleeve can
be removed and replaced.

EYE INJURY HAZARD!
Always wear safety glasses
during use to prevent
serious personal injury.
10 PSI MAX AIR PRESSURE!
Exceeding this PSI may
result in injury/tool damage.
Use manual pump only!
RESPIRATORY HAZARD!
Sanding produces fine
dust. Wear the appropriate
protection during use!

Operation
1. DISCONNECT BUFFER FROM POWER!
2. Install the sanding drum on the buffer shaft
using the spacers and flanges included with
the buffer (Figure 2).
3. Slide the sanding sleeve over the sanding
drum.
4. Use a bicycle pump (or other manual pump)
to inflate the drum until the sanding sleeve is
secure. Do not exceed the 10 PSI maximum
rating.

Operation Tips
• Adjust the pressure in the drum to fine-tune
its firmness for sanding contours.
• Always hold the workpiece firmly—the soft
surface of the drum will exert more force
on the workpiece than a traditional sanding
drum.
• Deflate the drum when not in use.

in personal injury and/or tool
damage
