INTENDED USE
The DW505 and DW520 heavy-duty hammerdrills have been designed for professional drilling
and hammerdrilling, screwdriving and light chipping, chiselling, demolition applications and for
carbide-tipped core drilling at various work sites (i.e., construction sites). DO NOT use under
humid conditions or in presence of flammable liquids or gases.
The DW505 and DW520 heavy-duty hammerdrills are professional power tools. DO NOT let
children come into contact with the tool. Supervision is required for those under 16 years of
age.
Side Handle
CAUTION: Always operate the tool with the side handle properly assembled. Hold tool with
both hands to maximize control.
A side handle is supplied wi th this hammerdrill. It clamps to the front of the gear case as shown
in Figure 1 and can be rotated 360˚ to permit right- or left-hand use.
Switch (Fig. 2)
To start hammerdrill, depress the trigger switch (A). To stop hammerdrill, release the trigger
switch.
WARNING: 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 personal injury could result.
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 hammer-
drill is mounted in a drill press stand or other wise held stationary.
VARIABLE SPEED
The variable speed trigger switch permits speed control. The farther the trigger switch is
depressed, the higher the speed of the hammerdrill.
NOTE: Use lower speeds for starting holes without a centerpunch, drilling in metal, plastics or
ceramics, or driving screws. Higher speeds are better for drilling in wood and composition board
and for using abrasive and polishing accessories.
REVERSING LEVER
The reversing lever (C) is used to reverse the hammerdrill for backing out screws or jammed
bits. It is located above the trigger, shown in Figure 2. To reverse the hammerdrill, turn it off and
push the reversing lever to the left (when viewed from the chuck end).
To position the lever for forward operation, turn the hammerdrill off and push the lever to the
right (when viewed from the chuck end).
High/Low Speed Operation (Fig. 1, 3)
The two speed gear drive in the dual range hammerdrill permits effective operation over an
extended range of applications with greater selection of accessories.
For LOW SPEED operation, the shift knob (D) located on the underside of the hammerdrill
should be rotated so the low speed setting is toward the front of the tool.
For HIGH SPEED operation, the shift knob (D) should be rotated so the high speed setting is
toward the front of the tool.
The gear train has been designed for shifting only when the unit is off. It may be necessary
however, to rotate the chuck slightly by hand to align the gears while turning the shift knob. DO
NOT ATTEMPT TO CHANGE SPEEDS by turning the shift knob when the tool is running. Doing
so will damage the gear train.
Hammer/Drill Selector (Fig. 4)
To switch the tool from the drilling mode to the hammering mode (or vice-versa) rotate the
selector (E) to the applicable symbol as shown in Figure 4.
For straight drilling, align selector with drill bit symbol.
For hammering, align selector with the hammer symbol, as shown in the figure.
NOTE: The selector must be in either drill or hammer/drill mode at all times. There are no
operable positions between the two.
Chuck
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.
To insert the bit, open chuck jaws by turning collar with fingers counterclockwise (when viewed
from the chuck end) and insert shank of bit about 1/2" (13 mm) into chuck. 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 release the bit, turn collar key counterclockwise in just one hole, then loosen the chuck by
hand turning collar counterclockwise (when viewed from the chuck end).
OPERATION
Drilling
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool
from power source before making any adjustments or removing/installing attachments
or accessories.
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.
1. Use sharp drill bits only. For WOOD, use the low speed setting and twist drill bits, spade
bits, power auger bits, or hole saws. For METAL, use the low speed setting and steel twist
drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-
tipped bits rated for percussion drilling. Use low speed for bits greater than 3/8" (10 mm).
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill 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.
4. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE
TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO
NOT CLICK TRIGGER ON AND OFF 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.

DRILLING IN METAL
USE ONLY in the low-speed gear range. Start drilling with slow speed and increase to full
power while applying firm pressure on the tool. A smooth even flow of metal chips indicates the
proper drilling rate. Use a cutting lubricant when drilling metals. The exceptions are cast iron and
brass which should be drilled dry.
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.
DRILLING IN WOOD
USE ONLY in the low-speed gear range. Start drilling with slow speed and increase to full
power while applying firm pressure on the tool. Holes in wood can be made with the same twist
drills used for metal. These bits may overheat unless pulled out frequently to clear chips from the
flutes. Work that is apt to splinter should be backed up with a block of wood.
DRILLING IN MASONRY
When drilling in masonry, use carbide tipped bits rated for percussion drilling and be certain that
the bit is sharp. For holes up to 3/8" (10 mm) diameter use the high-speed gear range. For holes
larger than 3/8" (10 mm), use the the low-speed gear range. Ensure that the hammer mode is
selected. Use a constant and firm force on the tool to drill most effectively. A smooth, even flow
of dust indicates the proper drilling rate.
Depth Rod
To adjust the depth rod, loosen the handle and move rod 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.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool
from power source before making any adjustments or removing/installing attachments
or accessories.
Cleaning
CAUTION: 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, depend-
ing 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.
