H4380 Buffer -11-
Buffing Tips
Here are some quick tips for getting the most out
of your buffer:
• Thoroughly clean all parts that you are plan-
ning to buff. Any kind of dirt, oil, rust, paint or
other film must be removed either chemically
or sprayed off with water. Make sure to dry off
parts with a rag after cleaning.
• Apply buffing compounds in small amounts at
a time. While the machine is running, press
the compound on the wheel for a couple of
seconds. Avoid using too much compound.
• Put your workpiece under the wheel when
you are loading the compound on the buffing
wheel. This way, you will catch any com-
pound that would normally be wasted on the
floor.
• Only use the area grayed-out in Figure 4 to
do the actual buffing. Contacting the work-
piece on areas outside of the grayed out area
may flip the workpiece out of your hands.
• Hold the workpiece tightly at all times while
buffing. One hand near the contact point will
give you better control.
• Keep buffing wheels raked out before each
use and when buildup gets heavy during use.
“Raking” means to clean the buffing wheels
with a wheel rake to remove buildup com-
pounds and metal particles. An old rough-cut
saw blade or a large hacksaw blade will also
work as an alternative to a wheel rake.
ALWAYS use light pressure when raking
wheels!
• Do not mix two different compounds on the
same wheel. For best results, use a separate
wheel for each compound.
• Use an upward stroke with heavy to moder-
ate pressure for cutting. Use a downward
stroke with light to pressure for polishing. See
Figure 5.

•Wear safety equipment when buffing. If the
buffer forces the workpiece out of your hand,
be prepared for it to come flying at you! Wear
safety glasses and a heavy leather apron.
Also, wear a dust mask to protect your lungs
from microscopic particulate that will be flying
off the wheel.
Remember, there is no substitute for experience.
Learning how to hold the workpiece, how much
pressure to apply, how to move the workpiece
against the wheel and how much compound to
use will require some trial-and-error.
