Rechargeable Battery Pack
This long life battery pack must be recharged when it fails
to produce sufficient power on jobs which were easily done
before. At the end of its technical life, discard it with due care for
our environment:
• Run the battery pack down completely, then remove it from
the tool.
• Li-Ion cells are recyclable. Take them to your dealer or a
local recycling station. The collected battery packs will be
recycled or disposed of properly.
Optional Accessories

WARNING: Since accessories, other than those offered
by
DeWALT
, have not been tested with this product, use
of such accessories with this tool could be hazardous.
To reduce the risk of injury, only

Cleaning

WARNING: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask when performing thisprocedure.

WARNING: Never use solvents or other harsh chemicals
for cleaning the non-metallic parts of the tool. These
chemicals may weaken the materials used in these parts.
Use a cloth dampened only with water and mild soap.
Never let any liquid get inside the tool; never immerse any
part of the tool into aliquid.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.

WARNING:To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
The charger and battery pack are notserviceable.
Lubrication
Your power tool requires no additionallubrication.
Electronic Speed Control
The electronic speed control feature functions 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,
the tool will compensate for the loading and maintain the
selected speed. If the speed selected by the control wheel is
2200 RPM, the tool will maintain 2200 RPM, as it isloaded.
• The electronic speed control operates only when the trigger
switch
4
is fullydepressed.
• The effect of electronic speed control is much easier to
observe at lower speed settings (2600 RPM and below), than
at highspeeds.
A conventional polisher running at a typical no-load speed of
2400 RPM slows down to about 2000 RPM under a polishing
load. Your DCM848 will continue to run at 2400 RPM (or any
speed you select with the control wheel) as a load is applied.
If the speed is too great, slow the tool down with either the
trigger switch or the controlwheel.
Polishing (Fig.E)
1. Without turning the tool on, grasp the handles of the tool
and pick itup.
2. Keep the tool away from your body and depress the
triggerswitch.
3. Make sure you have a firm grip on thehandles.
4. Move the tool evenly over the surface of the workpiece,
without applyingpressure.
5. Switch off the machine before taking the tool from
thesurface.
6. Check your work at shortintervals.
The auxiliary handle
5
can be easily changed to either side of
the tool for left-handed or right-handedoperation.
Use utmost care when power polishing around or over sharp
objects and contours. 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.

WARNING: High-speed rubbing action of the polishing
bonnet upon the workpiece surface can build a static
charge on the metal portions of this tool resulting in a
static shock whentouched.
