General Safety Rules
WARNING! Read and understand all instructions. Failure to follow all instructions list-
ed below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flam-
mable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
Grounded tools must be plugged into an outlet properly installed and grounded in accor-
dance with all codes and ordinances. Never remove the grounding prong or modify the
plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you
are in doubt as to whether the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low resistance path to carry electricity away
from the user. Applicable only to Class I (grounded) tools. The DW274W and DW286G units
are grounded.
Double insulated tools are equipped with a polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install
a polarized outlet. Do not change the plug in any way. Double insulation eliminates the
need for the three wire grounded power cord and grounded power supply system. Applicable
only to Class II (double insulated) tools. The DW251, DW252, DW255,DW257, DW260,
DW262, DW263, DW265, DW266, DW267, DW268, DW269, DW272, DW274, DW276,
DW281, DW282 and DW284 units are double insulated.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrig-
erators. There is an increased risk of electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an out-
let. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked “W-A” or
“W.” These cords are rated for outdoor use and reduce the risk of electric shock. 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 overheating.
The following table shows the correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heav-
ier the cord.

PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inat-
tention while operating power tools may result in serious personal injury,
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, cloth-
ing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be caught in
moving parts. Air vents often cover moving parts and should also be avoided.
Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your fin-
ger on the switch or plugging in tools that have the switch on invites accidents.
Remove adjusting keys or switches before turning the tool on. A wrench or key that is left
attached to a rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat,
or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
Use clamps or other practical way to secure and support the workpiece to a stable platform.
Holding the work by hand or against your body is unstable and may lead to a loss of control.
Do not force tool. Use the correct tool for your application. The correct tool will do the job bet-
ter and safer and the rate for which it is designed.
Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing acces-
sories, or storing the tool. Such preventative safety measures reduce the risk of starting the tool
accidentally.
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with
sharp cutting edges are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition
that may affect the tools operation. If damaged, have the tool serviced before using. Many acci-
dents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your model. Accessories
that may be suitable for one tool, may become hazardous when used on another tool.
SERVICE
Tool service must be performed only by qualified repair personnel. Service or maintenance per-
formed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.
Additional Safety Rules
Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live” and shock the operator.
Keep handles dry, clean, free from oil and grease. It is recommended to use rubber
gloves. This will enable better control
KEEP TOOL DRY FROM SWEAT DURING USE. Reduce risk of electric shock by preventing
perspiration or other liquids from entering the tool during use in hot/humid conditions. Use wrist-
bands, gloves, drying towels or cloths as necessary.
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 repro-
ductive 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
promote absorption of harmful chemicals.

Switch
To start tool, depress the trigger switch, shown in Figure 1. To stop tool, release the switch.
The variable speed trigger switch permits speed control. The farther the trigger switch is
depressed, the higher the speed of the tool.
To lock the switch in the on position for continuous operation, depress the trigger switch and
push up the locking button. The tool will continue to run. To turn the tool off, from a locked on
condition, squeeze and release the trigger once. Before using the tool (each time), be sure that
the locking button release mechanism is working freely. Be sure to release the locking
mechanism before disconnecting the plug from the power supply. Failure to do so will cause the
tool to start immediately the next time it is plugged in. Damage or injury could result.The
reversing lever is used to reverse the tool for backing out screws. It is located above the
trigger, shown in Figure 1. To reverse the screwdriver, turn it off and push the reversing lever to
the right (when viewed from the back of the tool). To position the lever for forward operation,
turn the tool off and push the lever to the left.
Dead Spindle Action
All DEWALT screwdrivers provide a dead output spindle to permit fasteners to be located
easily in the driving accessory. Clutches are held apart by light spring pressure permitting
the driving clutch to rotate without turning the driven clutch and accessory. When sufficient
forward pressure is applied to the unit, the clutches engage and rotate the spindle and
accessories. A reversing switch makes it possible to drive or loosen either right or left hand
screws.
Maintenance
CLEANING
With the motor running, blow dirt and dust out of all air vents with dry air at least once a
week. Wear safety glasses when performing this operation. Exterior plastic parts may be
cleaned with a damp cloth and mild detergent. Although these parts are highly solvent resist-
ant, NEVER use solvents.
CHANGING CLUTCHES
1. Remove clutch housing by unscrewing (left hand thread).
2. Clamp tool or clutch housing in a resilient clamp.USE CARE, the clutch housing can be
easily damaged.
3. Remove round clutch retaining rings with a very small screwdriver (see Figure 2).
4. Install new clutches and new retaining rings. Be careful to assemble the intermediate
clutch large end first toward the unit and then the spring. The spring should run against
the output clutch.
NOTE: If the output spindle slides toward inside of gear case, remove gear case and push
output spindle forward to expose retaining ring groove. Reassemble dead spindle spring
allowing no more than 1/4" projecting from end of spindle.
5. Relubricate clutches (see Parts Bulletin for D
EWALT lubricants identification).
LUBRICATION
All ball and needle bearings are factory lubricated for the life of the bearing.
