Motor
Your DEWALT tool is powered by a DEWALT-built
motor. Be sure your power supply agrees with the
nameplate marking. Voltage decrease of more than
10% will cause loss of power and overheating.
DEWALT tools are factory tested; if this tool does not
operate, check power supply.

INTENDED USE
The DWP849X heavy-duty polishers are designed
for professional use at various work sites (i.e.,
construction sites). Do not use under humid
conditions or in presence of flammable liquids or
gases.
The DWP849X heavy-duty polishers are professional
power tools. Do not let children come into contact
with the tool. Supervision is required when
inexperienced operators use this tool.
Auxiliary handle (fig. 1)
An auxiliary handle (F) is furnished with your tool
and can be installed on either side of the gear case.
This handle should be used at all times to maintain
complete control of the tool. A bale handle (H) is
also provided with the DWP849X and can be used
in place of the auxiliary handle.
Variable Speed Trigger Switch (fig. 1)
These tools are equipped with a variable speed
trigger switch that permits speed control from 0 to
3500 RPM. To turn the tool on, squeeze the trigger
switch (C) shown in Figure 1 until the tool starts to
run. The farther you depress the trigger, the faster it
will operate. Releasing the trigger turns the tool off.
Use lower speeds for applying liquid waxes and
polishes and higher speeds for removing dried
liquid. Use the highest speed (fully depress trigger)
for buffing the car to a final lustre.The tool can be
locked on for continuous use by squeezing the
trigger switch fully and depressing the lock button
(G) shown in Figure 1. Hold the lock button in as
you gently release the trigger switch. The tool will

ENGLISH

continue to run. To turn the tool off from a locked-
on position, squeeze and release the trigger switch
once. Do not unplug the tool with the switch in
the locked-on condition. Make sure the tool is not
locked on when plugging in. If the tool is plugged
back in with the switch in the locked-on position, the
tool will not run until the lock button (G) is depressed
(no-volt release).
NOTE: The trigger switch can only be locked
on with the tool running at the maximum RPM
designated by the speed control wheel (A).
Speed control Wheel (fig. 1)
The maximum speed of your tool can be changed
by rotating the speed control wheel (A) to the
desired setting. The wheel incorporates detents to
prevent inadvertent wheel movement and to facilitate
speed selection. For added versatility, the trigger
switch may be locked in its full on position and tool
speed changed by means of the speed control
wheel (A) alone.The electronic speed control not
only lets you select the speed to suit the job, but
also helps to maintain that speed as you load the
tool by pressing down. It’s this feature, coupled with
the variable speed trigger switch, that make this tool
such a value.
The speed control wheel (A) can be set for any
speed between 600 and 3500 RPM and the variable
speed switch will then control tool speed from zero
to the wheel setting. For example: A control wheel
setting of 2200 RPM will allow the variable speed
switch to operate the tool between zero and 2200
RPM, depending on how far the trigger switch is
depressed. A wheel setting of 600 RPM would allow
the switch to operate the tool from zero to 600
RPM.
The electronic speed control feature comes into play
whenever the trigger switch is fully depressed and
the tool is running at the selected speed determined
by the setting of the control wheel. As you load the
tool by pushing it down on the work surface, (with
the trigger fully depressed) the electronic circuit
inside the tool will compensate for the loading and
maintain the selected speed. If the speed selected
by the control wheel is 2200 RPM, as in the
example above, the tool will maintain 2200 RPM, as
it is loaded.
It is important to remember two things about
electronic speed control:
1. The electronic speed control operates only
when the trigger switch (C) is fully depressed.
2. The effect of electronic speed control is much
easier to observe at lower speed settings
(2600 RPM and below), than at high speeds.
As the tool approaches 3000 RPM, the effect
is considerably less dramatic.
Keep in mind that, with a conventional polisher
running at a typical no-load speed of 2400 RPM,
the tool slows down to about 2000 RPM under a
polishing load. Your DWP894X will continue to run
at 2400 RPM (or any speed you select with the
control wheel) as a load is applied. Since it doesn’t
slow down, the speed may be greater than you’re
used to, so some extra caution should 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.

In order to prevent the spindle of the tool from
rotating while installing or removing accessories, a
spindle lock button (E) 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.
Wool Ingestion Shields (fig. 1, 2)
The wool ingestion shields (K) are designed to
reduce the amount of wool, dust, and debris that
gets ingested by the motor during normal use. The
goal of the ingestion shields is to improve durability
as compared to a unit without the ingestion shields.
Each ingestion shield can be easily removed for
cleaning by removing the mounting screw (L),
followed by sliding the shield back towards the
trigger end of the tool and then lifting it off. The wool
ingestion shields can be cleaned with soap and
water and a soft bristle brush in the event they get
clogged with polish and debris. Clean the shields
as soon as you start to see buildup on the outside.
Your tool may come with a set of wool ingestion
shields. The wool ingestion shields are available
at extra cost from your local dealer or authorized
service center.

Soft Rubber Gear Case Cover (fig. 1)
The soft rubber gear case cover (J) is designed
to eliminate metal gear case scuffs on painted or
polished surfaces.
The soft rubber gear case cover can be removed
if required. To take off the cover, remove the three
mounting screws and lift the cover over the gear
case.
Your tool may come with a soft rubber gear case
cover. The soft rubber gear case cover is available
at extra cost from your local dealer or authorized
service center.

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 easier and faster
as you learn power polishing.
såå 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.å
så 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 TESTåSECTIONåYOUåCANåJUDGEå
the strength or cleaning action of your power
polish.

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.

handles of the tool and pick it up. Keep the
tool away from your body and depress the
trigger switch. 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-

Lubrication
DEWALT tools are properly lubricated at the factory
and are ready for use. Tools should be relubricated
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 lubrication.) This lubrication
should only be attempted by trained power tool
repairpersons such as those at DEWALT service
centers or other authorized service locations.
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.
