POLISHING
These instructions and suggestions are intended to familiarise new operators in
overall general operation of power polishing. You will develop your own techniques
which will make the job easier and faster as you learn power polishing.
You should use utmost care when power polishing around or over sharp objects
and contours of the car body. It is very important to use the correct pressure while
polishing various sections of an automobile body. For example, light pressure should
be applied when polishing over sharp edges of body panels, or over edges of the rain
gutter along the top.
Since everyone does not use the same type of power polish, we recommend you
clean and polish a test section on a flat area of the car first. From this test section,
you can judge the strength or cleaning action of your power polish.
Remember, all power polish is not the same. Different brands will react differently
on various painted surfaces. Also, you are now using a power polisher with power
polish. This is entirely different from any hand application which you may have done
before. Wash the car before power polishing it. Washing will remove loose dirt, scum,
road salt, etc. which could act as an abrasive and damage paint. Loose dirt, etc. will
also clog the polishing pad and you will have to clean it more often.
Without turning the tool on, grasp the handles of the tool and pick it up. Keep the tool
away from your body and turn the switch on. Make sure you have a firm grip on the
handles and operate the tool freely without forced effort or unnecessary pressure. The
side handle can be easily changed to either side of the tool for left-handed or right-
handed operation.
NOTE:
The high speed rubbing action of the polishing bonnet upon the surface of an
automobile can build a static charge on the metal portions of this tool. This can result
in a sensation of a very short mild electric shock when the metal area of the tool is
touched, and will be more noticeable on days when the humidity is low. This is a
harmless phenomenon but you are invited to bring the tool to a D
E
WALT Repair Centre
where it can be checked to assure that no electrical malfunction is present.
SANDING APPLICATION
WARNING: Shock Hazard.
To reduce the risk of serious personal injury, turn tool
off and disconnect tool from power source before making any adjustments or
removing/installing attachments or accessories.
Attaching and Removing Abrasive

Discs (Figure 7)
To attach the sanding disc,
push the hub of the clamp
washer through the centre of the sanding disc (L), as
far as it will go, then through the backing pad. Engage
the clamp washer threads on the tool spindle and
thread assembly clockwise, completely down on the
spindle. Hold the spindle from rotating by engaging the
spindle lock button (E).
To remove the abrasive disc,
use a cloth or glove to protect your hand. Turn the disc
assembly counterclockwise. Hold the spindle from rotating by engaging the spindle
lock button.
Sanding (Figure 8)
FIGURE 8
When using an abrasive disc, hold the tool so that
an angle of 10° to 15° exists between the disc and
the work. If only the outer edge of the sanding disc
is used, a rough cut will result. If the sanding disc is
pressed flat against the work, the sanding action will
be irregular and bumpy, and the tool will be difficult
to control.
MOTOR BRUSHES
WARNING: Shock Hazard.
To reduce the risk of serious personal injury, turn
tool off and disconnect tool from power source before making any adjustments or
removing/installing attachments or accessories.
Be sure tool is unplugged before inspecting brushes. Carbon brushes should be
regularly inspected for wear. To inspect brushes, unscrew the plastic brush inspection
caps (located in the sides of the motor housing) and the spring and brush assemblies
may be withdrawn from the tool. Keep brushes clean and sliding freely in their guides.
Carbon brushes have varying symbols stamped into them, and if the brush is worn
down to the line closest to the spring, they must be replaced. New brush assemblies
are available at D
E
WALT Repair Centres. Your tool is equipped with the D
E
WALT
brush CHECKPOINT™ system. When the brushes become worn out, the tool will
automatically stop and prevent damage to the motor.
