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.
• 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 performance. Follow instructions for lubricating
and changing accessories. Inspect tool cords periodically 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 changing 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
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 heavier the cord.

not operate tool when you are tired.
• CHECK DAMAGED PARTS. Before further use of the tool, a guard
or other part that is damaged 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 Rotary
Hammers
• WEAR SAFETY GOGGLES or other eye protection.
• WEAR EAR PROTECTORS when hammering for extended
periods.
• ALWAYS USE THE SIDE HANDLE supplied with the tool. Keep a
firm grip on the hammer when it is operating.
• DON’T OVERREACH. Maintain a firm, balanced working stance.
When necessary, use only properly positioned, safe platforms,
ladders and scaffolds, to do the job safely.
• Hammer bits and tools get hot in operation. Wear gloves when
touching them.
• CAUTION: When drilling or driving into walls, floors or wherever
“live” electrical wires may be encountered, DO NOT TOUCH ANY
FRONT METAL PARTS OF THE TOOL! Hold the tool only by the
plastic handle to prevent shock if you drill or drive into a “live” wire.

Motor
Your tool is powered by a D
EWALT built motor. Be sure your power
supply agrees with nameplate marking.
Voltage decrease of more than 10% will cause loss of power and
overheating. All D
EWALT tools are factory tested; if this tool does not
operate, check the power supply.
Side Handle and Depth Rod
For operating convenience, the side handle can be installed in front
or rear positions. Always operate the tool with the side handle
properly assembled.
TO MOUNT IN FRONT POSITION (FIG. 1)
1. Unscrew the side handle and disassemble the side handle clamp.
2. Snap the steel ring over the collar behind the tool holder. Squeeze
both ends together, mount the bush and insert the pin.

Soft Start Feature (DW541, DW532,
DW533, DW545)
The soft start feature allows you to build up speed slowly, thus
preventing the drill bit from walking off the intended hole position
when starting. The soft start feature also reduces the immediate
torque reaction transmitted to the gearing and the operator if the
hammer is started with the drill bit in an existing hole.
Torque Limiting Clutch
All rotary hammers are equipped with a torque limiting clutch that
reduces the maximum torque reaction transmitted to the operator in
the case of a jamming drill bit. This feature also prevents the gearing
and motor from stalling. The torque limiting clutch has been factory
set and cannot be adjusted.
Electronic Speed and Impact Control
(DW541, DW532, DW533, DW545)
(Fig. 5) The electronic speed and impact control allows the use of
smaller drill bits without the risk of bit breakage, drilling into light and
brittle materials without shattering, and optimal tool control for
precise chiseling. To set the control dial: Turn the dial to the desired
level. The higher the number, the greater the speed and impact
energy. With dial settings from “1” to “5” (full power) the tool is
extremely flexible and adaptable for many different applications. The
required setting depends on the bit size and hardness of material
being drilled.
Mode Selector
(Fig. 6) Your rotary hammer (all units except DW530) can be used in
two operating modes: Hammer drilling (simultaneous rotating and
impacting for all concrete and masonry drilling operations) and
Hammering only with spindle lock (impacting only- for light
chipping, chiseling, and demolition applications. The chisel can be
locked into 8 different positions.
NOTE: Also in this mode, the hammer can also be used as a lever to
free a jammed drill bit.
To select the required operating mode, rotate the selector lever
over the safety lock until it covers the symbol.
SERVICE AND POWER INDICATOR LEDS (DW541, DW532,
DW533, DW545)
(Fig. 5) The RED service indicator LED lights up when the carbon
brushes are nearly worn out to indicate that the tool needs servicing.
After approximately 8 hours of use the motor will automatically be
shut off. Take the tool to a D
EWALT service location for routine
inspection and maintenance.
The GREEN power-ON indicator LED lights up when the tool is
switched ON. If the indicator LED is lit but the tool does not start, this
indicates a motor related problem. If the indicator LED does not light
up and the tool does not start, this indicates an ON/OFF switch or
cord related problem.
DRILLING WITH A SOLID BIT
1. Set the speed and impact control dial (DW541, DW532, DW533,
DW545).
2. Set the model selector to the “hammer drilling” position (for all
units except DW530).
3. Insert the appropriate drill bit.
4. Fit and adjust the side handle.
5. If necessary, set the drilling depth rod.
