SAVE THESE INSTRUCTIONS FOR FUTURE USE
Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than
10% will cause loss of power and overheating. D
not operate, check power supply.
COMPONENTS (FIG. 1, 2)
WARNING: Never modify the power tool or any part of it. Damage or personal injury could result.
A. Trigger switch
B. Reversing lever
C. Side handle
INTENDED USE
The DW140 heavy-duty end handle drill is designed for professional drilling at various work sites
(i.e., construction sites). DO NOT use under wet conditions or in presence of flammable liquids or
gases.
These heavy-duty end handle drills are professional power tools. DO NOT let children come into
contact with the tool. Supervision is required when inexperienced operators use this tool.
Switches (Fig. 1)
Pulling the trigger switch (A) turns the tool "ON"; releasing the trigger switch turns the tool "OFF".
For controlling the rotational direction of the spindle, there is a lever (B), integral to and on top of the
trigger switch. For drilling (forward position) this lever should be slanted to the left side of the tool
(viewing from behind the handle); for easing drill bits out of tight holes (reverse position) it should be
slanted to the right side of the tool. A built-in mechanical interlock prevents changing the direction
of the tool unless the trigger switch is released. After any reversing, return lever to forward position.
Side Handle (Fig. 2)
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: 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 (C) is provided that will thread into the holes provided on the gear case. Because of
the extremely high torque of this drill, a side handle must be used when operating this drill. Screw
the side handle into the hole in the gear case of your drill and tighten securely.
OPERATION
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.
Inserting Bit
1. Open the chuck jaws by turning collar with fingers and insert bit fully into the chuck. Tighten
chuck collar by hand.
2. 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.
3. To release bit, turn chuck key counter clockwise in just one hole, then loosen chuck by hand.
Drilling
1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole
saws. For METAL, use high-speed steel twist drill bits or hole saws. For MASONRY, such as
brick, cement, cinder block etc., use carbide-tipped bits.
2. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a
wood "back-up" block to prevent damage to the material.
3. 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.
4. Hold drill firmly to control the twisting action of the drill. Use side handle.
CAUTION: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the
drill firmly to control the twisting action and avoid injury.
5. 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 OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL—
THIS CAN DAMAGE THE DRILL.
6. To minimize stalling on breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
DRILLING IN METAL
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should
be drilled dry. The cutting lubricants that work best are sulphurized cutting oil or lard oil; bacon
grease will also serve the purpose.
DRILLING IN WOOD
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. For larger holes, use Power Drill Wood
Bits. Work that is apt to splinter should be backed up with a block of wood.
Chuck
1. Always completely insert the shank of the drill bit or accessory in the chuck. This permits full
gripping power and prevents cocking the chuck jaws. When using drill bits or accessories with
3 "flats" on the shank, the chuck jaws should be located on the center of these flats.
2. Use all three holes in the chuck body to tighten the jaws. Insert the chuck key into each hole
and tighten as much as possible. To release the drill bit, use the chuck key in only one hole.
3. Use only a chuck key to tighten or loosen the chuck jaws.
Chuck Removal (Fig. 3, 4, 5)
1. Place chuck key in chuck as shown in Figure 4.
2. Using a wooden mallet or similar object, strike key sharply in a clockwise direction. This will
loosen screw inside chuck (Fig. 4).
3. Open chuck jaws fully. Insert screwdriver (or 3/16", 5mm, hex wrench (E) if required) into front
of chuck between jaws to engage screw head (F).
4. Remove screw by turning clockwise (left-hand thread).
5. Place key in chuck as shown in Figure 5.
6. Using a wooden mallet or similar object, strike key sharply in a counterclockwise direction. This
will loosen chuck so that it can be unscrewed by hand (Fig. 5).
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
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.
Motor Brushes
Be sure tool is unplugged before inspecting brushes. Carbon brushes should be regularly inspected
for wear. To inspect brushes, unscrew the plastic brush inspection caps (located in the sides of the
motor housing) and withdraw the spring and brush assemblies from the tool. Keep brushes clean
and sliding freely in their guides. Carbon brushes have varying symbols stamped into them, and if
the brush is worn down to the line closest to the spring, it must be replaced. New brush assemblies
are available at D
WALT certified service centers.
