General Safety Rules
WARNING! Read and understand all instructions. Failure to follow all instructions listed
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
flammable 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 accordance 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.
• 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
need for the three wire grounded power cord and grounded power supply system. Applicable
only to Class II (double insulated) tools. The DW252, DW253, DW255, DW257, DW260,
DW266, DW267, DW268, DW269, DW272, DW276, DW281 and DW284 units are double
insulated.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. 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
outlet. 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 gauge. The smaller the gauge
number, the heavier 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 inattention 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, clothing, 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
finger 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
better 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
accessories, 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 accidents 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 performed 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
wristbands, 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
construction activities contains chemicals known to cause cancer, birth defects or other
WALT
E
reproductive 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).
WALT TOOL, Your risk from these exposures varies, depending on how often you do this type of work. To
E
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
eliminates the
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 D WALT screwdrivers provide a dead output spindle to permit fasteners to be located easily
E
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.
Accessory Assembly
The 1/4" hex drive ball lock chuck is used on all depth sensitive and drywall screwdrivers.
Assemble accessories by engaging the hex spindle and tapping lightly on the accessory until
it snaps in place. Usually pliers are required to remove the accessory by pulling forward. The
1/4" hex drive quick change chuck (Figure 2), is used on all Versa Clutch™ units. A ball retainer
provides positive locking of all accessories in the chuck. Pull forward on the ball retainer and hold
while inserting or removing accessories. Release for positive accessory retention.
