be observed until you get the "feel" of your polisher. If you feel the speed is too great, you can,
of course slow the tool down with either the trigger switch or the control wheel.
Spindle Lock Button (Fig. 1)
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
In order to prevent the spindle of the tool from rotating while installing or removing accessories,
a spindle lock button has been provided in the gear head of the machine. To lock the spindle,
depress and hold the lock button. NEVER DEPRESS THE SPINDLE LOCK BUTTON WITH
THE TOOL RUNNING OR COASTING.
Attaching and Removing Polishing Pads (Figures 4 & 5)
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
To attach pad, push the hub of the clamp washer through the hole in the center of the polishing
pad as far as it will go. Engage the hexagonal hole in the backing pad. Holding the three pieces
firmly together, place the assembly on the tool spindle. Hold the spindle lock button while turn-
ing the pads clockwise to thread them completely on the spindle.
To remove the pads, turn them by hand in the opposite direction from normal rotation to allow
lock button to engage spindle, then unscrew pads in normal direction for right hand thread.
NOTE: If you are using a polishing bonnet, rather than a pad, put clamp washer on first, pull bon-
net completely over backing pad and pull draw strings tight Tie bow knot and push knot and all
loose string completely under the inside, cloth edge of the polishing bonnet.
WARNING: TIED KNOT AND ALL STRINGS MUST BE TUCKED ENTIRELY UNDER THE
CLOTH APRON. FAILURE TO DO SO MAY CAUSE SERIOUS INJURY.
Polishing
These instructions and suggestions are intended to familiarize new operators in overall general
operation of power polishing. You will develop your own techniques which will make the job eas-
ier 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 pol-
ish 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 dif-
ferent 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 auto-
mobile can build a static charge on the metal portions of this tool. This can result in a sensa-
tion 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 WALT service center where it can be checked to assure
E
that no electrical malfunction is present.
Sanding Application (DW849 only)
ATTACHING AND REMOVING ABRASIVE DISCS (FIGURES 6, 7, AND 8)
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
To attach the sanding disc, push the hub of the clamp washer through the center of the sanding
and phenolic discs, as far as it will go, and also 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.
To remove the abrasive disc, use a cloth or glove to protect your hand. Turn the disc assembly
counterclockwise (Figure 8). Hold the spindle from rotating by engaging the spindle lock button.
Sanding (DW849 only)
(See Figure 9) 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 irregu-
lar and bumpy, and the tool will be difficult to control.
Cleaning
Blowing dust, polishing bonnet lint, and grit out of the motor housing using compressed air is a
necessary regular maintenance procedure. Dust and grit containing metal particles often accu-
mulate on interior surfaces could create an electrical shock hazard if not frequently cleaned out.
CAUTION: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of
the tool. Use clean, dry rag only.
Lubrication
D WALT tools are properly lubricated at the factory and are ready for use. Tools should be relu-
E
bricated regularly every sixty days to six months, depending on usage. (Tools used constantly
on production or heavy-duty jobs and tools exposed to heat may require more frequent lubrica-
tion.) This lubrication should only be attempted by trained power tool repairpersons such as
those at D WALT service centers or other authorized service locations.
E
Motor Brushes
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 sym-
bols 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 service centers; see "Tool, Electric" in the
yellow pages.
Accessories
Recommended accessories for use with your tool are available at extra cost from your distribu-
tor or your local service center. A complete listing of service centers is included with your tool.
CAUTION: The use of any non-recommended accessory may be hazardous.
Call 1-800-4-D WALT or contact D WALT Industrial Tool Co., 701 East Joppa Road, Baltimore,
E E
MD 21286.
Use only accessories having a maximum operating speed at least as high as the highest "NO
LOAD RPM" marked on the tool's nameplate. This precaution applies to any accessory on any
tool.
Rubber Backing Pads: 7" Quick Change Super Flexible Rubber Backing Pad (includes Clamp
Washer)
Polishing Bonnets and Pads: D WALT has an array of polishing bonnets and pads for 7" and
E
9" polishers. See your local D WALT service center.
