WARNING: Never modify the power tool or any part of it. Damage or personal injury could result.
A. Trigger switch D. Side handle
B. Locking button E. Selector dial
C. Reversing lever F. Depth rod
INTENDED USE
These heavy-duty hammerdrills are designed for professional drilling and hammerdrilling. DO NOT
use under humid conditions or in presence of flammable liquids or gases.
These heavy-duty hammerdrills are professional power tools. DO NOT let children come into
contact with the tool. Supervision is required when inexperienced operators use this tool.
Switch (Fig. 2)
To start hammerdrill, depress the trigger switch (A). To stop hammerdrill, release the switch.
To lock the trigger switch in the ON position for continuous operation, depress the trigger switch
and push up the locking button (B). 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.
Do not lock the switch ON when drilling by hand so that you can instantly release the trigger switch
if the bit binds in the hole. The locking button is for use only when the hammerdrill is mounted in
a drill press stand or other wise held stationary. Be sure to release the locking mechanism before
disconnecting the plug from the power supply. Failure to do so will cause the hammerdrill to start
immediately the next time it is plugged in. Damage or injury could result.
VARIABLE SPEED TRIGGER SWITCH (FIG. 2)
The variable speed trigger switch (A) permits speed control. The farther the trigger switch is
depressed, the higher the speed of the hammerdrill.
NOTE: Use lower speeds for starting holes, drilling in plastics or ceramics or driving screws.
REVERSING LEVER (FIG. 2)
The reversing lever (C), located above the trigger switch, changes the direction of rotation of the
hammerdrill and is used when backing out screws and jammed drill bits.
To operate the tool in reverse, release the trigger switch and push the lever to the left (when viewed
from the chuck end).
To operate the drill in forward, release the trigger switch and push the lever to the right (when viewed
from the chuck end).
Return the reversing lever to the forward position after all operations in reverse are completed.
Side Handle (Fig. 1)
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side
handle properly installed. Failure to do so may result in the side handle slipping during tool
operation and subsequent loss of control. Hold tool with both hands to maximize control.
A side handle (D) is supplied with this hammerdrill. It clamps to the front of the gear case as shown
in Figure 1 and can be rotated 360˚ for right- or left- hand use.
After the side handle is rotated into position, it should be pushed rearward until the slots (G) on the
lip of the side handle are aligned and fully engaged with the projecting tabs (H) on the underside of
the gear case. The side handle is then securely clamped by turning clockwise until tight.
Hammer/Drill Selector (Fig. 1)
To switch the tool from the drilling mode to the hammering mode (or vice-versa) rotate the selector
dial (E) on the applicable symbol shown in Figure 1. For straight drilling, align the drill bit symbol
toward the chuck. For hammering, align the hammer symbol with the lever, as shown.
NOTE: The selector must be in either drill or hammer/drill mode at all times. There are no operable
positions between the two modes.
Keyed Chuck (Fig. 1)
Open chuck jaws by turning collar with fingers and insert shank of bit about 3/4" (19 mm) into chuck
(I). Tighten chuck collar by hand. Place chuck key in each of the three holes, and tighten in clockwise
direction. It's important to tighten chuck with all three holes to prevent slippage. To release bit,
turn chuck key counterclockwise in just one hole, then loosen the chuck by hand. Any authorized
D WALT service center can install a keyless chuck in place of a keyed chuck.
e
Depth Rod (Fig. 1)
To adjust the depth rod, loosen the side handle (D) and move depth rod (F) so that the distance
between the end of the rod and the end of the bit equals the desired drilling depth. When drilling
with depth rod, stop when end of rod reaches surface of material.
OPERATION
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored
or clamped firmly. If drilling thin material, use a wood "back-up" block to prevent damage to the
material.
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side
handle properly installed. Failure to do so may result in the side handle slipping during tool
operation and subsequent loss of control. Hold tool with both hands to maximize control.
WARNING: Do not attempt to tighten or loosen drill bits (or any other accessory) by gripping the
front part of the chuck and turning the tool on. Damage to the chuck and personal injury may occur.
WARNING: Burn Hazard. ALWAYS wear gloves when changing bits. Accessible metal parts on
the tool and bits may get extremely hot during operation. Small bits of broken material may damage
bare hands.
DRILLING OPERATION
1. Use sharp drill bits only. For WOOD, begin with low speed and use twist drill bits, spade bits,
power auger bits or hole saws. For METAL, begin with low speed and use steel twist drill bits or
hole saws. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass
which should be drilled dry. For MASONRY, use carbide-tipped bits or masonry bits. A smooth,
even flow of dust indicates the proper drilling rate.
NOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel can be made easier if a pilot hole
[5/32" (4 mm) to 3/16" (5 mm)] is drilled first.
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit
biting, but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the drill.
WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip
the drill firmly with both hands to control the twisting action and avoid injury.
4. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN
DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.

7. With variable speed drills there is no need to center punch the point to be drilled. Use a slow
speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
HAMMERDRILL OPERATION
1. When drilling, use just enough force on the hammer to keep it from bouncing excessively or
"rising" off the bit. Too much force will cause slower drilling speeds, overheating, and a lower
drilling rate.
2. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit
when drilling as this will cause clogging of the bit flutes and a slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the
hole with the tool still running to help clear debris from the hole.
4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of dust indicates the
proper drilling rate.
MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To
minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing
this.
WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals may weaken the plastic 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.
Lubrication
Your tool was properly lubricated before leaving the factory. In from two to six months, depending
upon use, take or send your tool to an authorized service center for a complete cleaning, inspection
and lubrication. Tools used constantly on production jobs will need relubrication more often. Also,
tools "out of service" for long periods should be relubricated before being put back to work.
