Important Safety Instructions
WARNING: When using electric tools, basic safety precautions should always
be followed to reduce risk of fire, electric shock, and personal injury, including
the following:
READ ALL INSTRUCTIONS
Grounding Instructions
(DW880, DW888)
This tool should be grounded while in use to protect the operator from electric shock. The tool
is equipped with a 3-conductor cord and 3-prong grounding type plug to fit the proper ground-
ing type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire.
Never connect the green (or green and yellow) wire to a live terminal. If your unit is intended for
use on less than 150 V, it has a plug that looks like that shown in sketch A. If it is for use on 150
to 250 V, it has a plug that looks like that shown in sketch D. An adapter, sketches B and C, is
available for connecting sketch A type plugs to 2-prong receptacles. The green-colored rigid ear,
lug, or the like, extending from the adapter must be connected to a permanent ground, such as
a properly grounded outlet box. No adapter is available for a plug as shown in sketch D.
ADAPTER SHOWN IN FIGURES B and C IS NOT FOR USE IN CANADA.
Double Insulation (DW887)
Double insulated tools are constructed throughout with two separate layers of electrical insula-
tion or one double thickness of insulation between you and the tool’s electrical system. Tools
built with this insulation system are not intended to be grounded. As a result, your tool is
equipped with a two prong plug which permits you to use extension cords without concern for
maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety precautions when operating
this tool. The insulation system is for added protection against injury resulting from a possible
electrical insulation failure within the tool.
CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or
replace damaged cords.
Polarized Plugs (DW887)
Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk of
electric shock. When provided, this plug will fit in the polarized outlet only one way. If the plug
does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electri-
cian to install the proper outlet. Do not change the plug in any way.
Safety Instructions For All Tools
KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don’t expose power tools to rain. Don’t use
power tools in damp or wet locations. Keep work area well lit. Do not use tool in presence of
flammable liquids or gases.
GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For
example; pipes, radiators, ranges, and refrigerator enclosures.
KEEP CHILDREN AWAY. Do not let visitors contact tool or extension cord. All visitors should
be kept away from work area.

STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked-up
place — out of reach of children.
DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.
USE RIGHT TOOL. Don’t force small tool or attachment to do the job of a heavy-duty tool.
Don’t use tool for purpose not intended.
DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in moving
parts. Rubber gloves and non-skid footwear are recommended when working outdoors.
Wear protective hair covering to contain long hair. Air vents often cover moving parts and
should also be avoided.
USE SAFETY GLASSES. Also use face or dust mask if operation is dusty.
DON’T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle.
Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It’s safer than using your hand and it
frees both hands to operate tool.
DON’T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer perfor-
mance. Follow instructions for lubricating and changing accessories. Inspect tool cords peri-
odically and if damaged, have repaired by authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECT OR LOCK OFF TOOLS when not in use, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys
and adjusting wrenches are removed from tool before turning it on.
AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger on switch. Be sure switch
is off when plugging in.
EXTENSION CORDS. Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting in loss of power and overheat-
ing. The following table shows the correct size to use depending on cord length and name-
plate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension
cords intended for use outdoors and so marked.
STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool when you
are tired.
CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is dam-
aged should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment of moving parts, binding of moving parts, breakage of
parts, mounting, and any other conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced by an authorized service center
unless otherwise indicated elsewhere in this instruction manual. Have defective switches
replaced by authorized service center. Do not use tool if switch does not turn it on and off.
Additional Safety Instructions for Grinders
ALWAYS WEAR EYE PROTECTION.
KEEP GUARDS IN PLACE.
Use only grinding wheels having a maximum operating speed at least high as “No
Load RPM” marked on the tool’s nameplate.
Before using, inspect recommended accessory for cracks or flaws. If such a crack or
flaw is evident, discard the accessory. The accessory should also be inspected whenever you
think the tool may have been dropped.
When starting the tool (with a new or replacement wheel installed) hold the tool in a
well protected area and let it run for one minute. If the wheel has an undetected crack or
flaw, it should burst in less than one minute. Never start the tool with a person in line with the
wheel. This includes the operator.
In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop
the tool and inspect the wheel.
ALWAYS USE GUARDS with depressed center wheels or flaring cup grinding wheels.
Clean your tool out periodically.
Do not operate this tool for long periods of time. Vibration caused by the operating action
of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide
extra cushion, take frequent rest periods, and limit daily time of use.
CAUTION: Wear appropriate hearing protection during use. Under some conditions and
duration of use, noise from this product may contribute to hearing loss.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
lead from lead-based paints,
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may pro-
mote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
