SAFETY INSTRUCTIONS cont.
WARNING: BE SURE to read and understand all instructions in this manual
before using this power tool. Failure to follow all instructions may result in electric
shock, fire and / or serious personal injury.
WORK AREA SAFETY
1. Keep your work area clean and well lit. Cluttered workbenches and dark areas
invite accidents.
2. 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.
3. Keep bystanders, children and visitors away while operating a power tool.
Distractions can cause you to lose control.
4. Make your workshop childproof with padlocks and master switches. Lock
tools away when not in use.
5. MAKE SURE the work area has ample lighting so you can see the work and that
there are no obstructions that will interfere with safe operation BEFORE using your
power tool.
PERSONAL SAFETY
1. KNOW your power tool. Read the operator’s manual carefully. Learn the tool’s
applications and limitations, as well as the specific potential hazards related to this tool.
2. STAY ALERT, watch what you are doing and use common sense when operating a

tools with sharp cutting edges are less likely to bind and are easier to control.
7. CHECK for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have the
tool serviced before using. Many accidents are caused by poorly maintained tools.
8. USE ONLY accessories that are recommended for this tool. Accessories that
may be suitable for one tool may become hazardous when used on another tool.
ELECTRICAL SAFETY
! WARNING: Do not permit fingers to touch the terminals of plug when
installing or removing the plug from the outlet.
1. 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.

SERVICE SAFETY
EXTENSION CORDS
Use a proper extension cord. ONLY use cords listed by Underwriters Laboratories (UL).
Other extension cords can cause a drop in line voltage, resulting in a loss of power and
overheating of tool. For this tool an AWG (American Wire Gauge) size of a least 14-gauge
is recommended for an extension cord of 25 - ft. or less in length. Use 12 -gauge for an
extension cord of 50 -ft. Extension cords 100-ft. or longer are not recommended.
Remember, a smaller wire gauge size has greater capacity than a larger number
(14 - gauge wire has more capacity than 16-gauge wire; 12-gauge wire has more capacity
than 14 - gauge). When in doubt use the smaller number. When operating a power tool
outdoors, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for
outdoor use and reduce the risk of electric shock.
! CAUTION: Keep the extension cord clear of the working area. Position
the cord so that it will not get caught on lumber, tools or other obstructions while
you are working with a power tool.
! WARNING: Check extension cords before each use. If damaged replace
immediately. Never use tool with a damaged cord since touching the damaged
area could cause electrical shock, resulting in serious injury.

4. Start drilling in wood with slow speed and increase to full power while applying firm
pressure on the hammer drill.
5. Pull the bit out of the hole frequently to clear the wood chips away from the flutes to
help keep the bit from overheating.

ROTARY DRILLING (Fig. 14) cont.
OPERATING THE DRILL AS A HAMMER DRILL
6. Always clamp the workpiece firmly. If
Fig. 14
drilling thin material, use a wood “back-up”
block to prevent splintering or damage to
the workpiece.
7. 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.
8. Hold the hammer drill firmly to control the
twisting action of the hammer drill and bit.
9. IF HAMMER DRILL STALLS, it is usually
because it is being overloaded or
improperly used. RELEASE TRIGGER
SWITCH IMMEDIATELY, remove drill bit
from workpiece, and determine cause of
stalling. DO NOT START AND STOP A
STALLED DRILL BY QUICKLY APPLYING
AND RELEASING PRESSURE ON THE
TRIGGER SWITCH. THIS CAN
DAMAGE THE DRILL.
10. To minimize stalling or breaking through
the workpiece, reduce pressure on the
hammer drill and ease the bit through the last part of the hole.
11. Keep the motor running when pulling the bit out of a drilled hole. This will help prevent
the bit from jamming.
12. With variable speed there is no need to use a center punch at the point to be drilled.
Just use a slow speed to start the hole and accelerate by applying pressure to the
trigger switch when the hole is deep enough to drill without the drill bit skipping out
of the hole.
13. When drilling in metal start drilling with slow speed and increase to full power while
applying pressure on the hammer drill. A smooth even flow of metal chips indicates
proper drilling rate. 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 sulfurized cutting oil or lard oil; bacon grease will also serve the purpose.
When using your drill for percussion hammer drilling applications, make sure you have the
Rotary and Hammer Drilling Selector Switch in the Hammer Drilling position
(see Page 13, Fig. 4).
NOTE: Large holes in steel (5/16 to 1/2 inches) can be made more easily if a
pilot hole 5/32 to 3/16-inch is drilled first.
14. When driving screws and various types of fasteners, always use the proper driving bit
matched to the screw or fastener. Start the driving action using a constant force on the
fastener at a lower speed and torque, slowly increasing the speed and torque to
effectively drive and set the fastener in its finished position.
18
NOTE: When unplugging the drill, first make sure that the Power Lock-On
Feature is not engaged, by pressing on the trigger switch to release it. Failure
to do so will cause the hammer drill to start immediately the next time it is
plugged in. Property damage or serious personal injury could result.
HAMMER DRILLING (Fig. 15)
1. Always unplug the drill when
Fig. 15
installing or removing bits and
accessories.
2. When hammer drilling in masonry
such as brick, concrete, cinder
block, stone and tile, use only
carbide tipped bits rated for
percussion drilling and be certain
that the bit is sharp.
3. Make sure that the hammer drill
mode is selected and that the bit
is securely installed in the chuck.
4. Use a constant and firm force on
the hammer drill to drill effectively.
A smooth, even flow of dust from
the hole indicates the proper
hammer drilling rate.
5. Start hammer drilling at slower speeds and increase to full speed while applying firm
pressure on the hammer drill.
6. When hammer drilling, use just enough force on the drill to keep it from bouncing
excessively or “rising” off the bit. Too much force will cause slower drilling speeds,
overheating, and a slower drilling rate.
7. Drill straight and keep the bit at a right angle to the work (the bubble level will help).
Do not exert side pressure on the bit when hammer drilling, as this will cause clogging
of the bit flutes, overheating, and a slower drilling speed.
8. When hammer drilling deeper holes, pull the bit partially out of the hole frequently
(with the drill still running), to help clear debris from the hole. This will help keep the bit
form overheating and produce a cleaner drilled hole.

MAINTENANCE
!
MAINTENANCE cont.
WARNING: To ensure safety and reliability, repairs, maintenance and
adjustments MUST be performed by a qualified service technician at a
Sears Service Center.
! WARNING: For your safety, ALWAYS turn off switch and unplug drill from
the power source before performing any maintenance or cleaning.
It has been found that electric tools are subject to accelerated wear and possible
premature failure when they are used to work on fiber glass boats and sports cars,
wallboard, spackling compounds or plaster. The chips and grindings from these materials
are highly abrasive to electrical tool parts, such as bearings, brushes, commutators, etc.
Consequently, it is not recommended that this tool be used for extended work on any
fiberglass material, wallboard, spackling compound or plaster. During any use on these
materials, it is extremely important that the tool is cleaned frequently by blowing with
an air jet.
! WARNING: Always wear safety goggles or safety glasses with side shields
during power tool operations, or when blowing dust. If operation is dusty, also
wear a dust mask.
ROUTINE MAINTENANCE
! WARNING: DO NOT at any time let brake fluids, gasoline, petroleum-based
products, penetrating oils, etc. come in contact with plastic parts. Chemicals can
damage, weaken or destroy plastic, which may result in serious personal injury.
Periodic maintenance allows for long life and trouble-free operation. A cleaning, lubrication
and maintenance schedule should be maintained. As a common preventive maintenance
practice, follow these recommended steps:
! WARNING: For your safety, ALWAYS turn off switch and unplug saw from
the power source before performing any maintenance or cleaning.
CHUCK REMOVAL
(Fig. 16, 16a and 16b)
Fig. 16
The chuck may be removed and replaced
with a new one.
1. Unplug the hammer drill.

injury, ALWAYS disconnect the plug
from power source BEFORE
assembling parts, making adjustments
or changing bits.
2. Insert a 5 /16-in. or larger hex key into the
chuck of the drill and tighten the chuck
jaws securely with the chuck key and
spindle lock.
3. Tap the hex key sharply with a mallet in a
clockwise direction. This will loosen the
screw in the chuck for easy removal.
4. Open the chuck jaws and remove the
hex key. Using a screwdriver, remove the
chuck screw by turning it in a clockwise
direction (see Fig. 16a). Note that the
chuck screw has left hand threads and
clockwise direction loosens instead of
tightens.
5. Insert the hex key into the chuck and
tighten the chuck jaws securely. Tap
sharply with a mallet in a counterclockwise
direction (see Fig.16b). This will loosen
the chuck on the spindle. It can now be
unscrewed by hand.
1. When work has been completed, clean the tool to allow smooth functioning of the tool
over time.
2. Use clean damp cloths to wipe the tool.
3. Check the state of all power cords.
4. Keep the motor air vent openings free from oil, grease and sawdust or woodchips,
and store tool in a dry place.

5. Be certain that the chuck and jaws are well lubricated with a light machine oil, particularly
after lengthy exposure to damp and/or dirty conditions.
6. Apply a light coat of machine oil to the surface of the chuck face and jaws from time
to time for rust resistance.
