GENERAL SAFETY RULES USA002-2
(For All Tools)
WARNING:
Read and understand all instructions. Failure to follow all
instructions listed below, may result in electric shock, fire and/or
serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite acci-
dents.
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. Distrac-
tions can cause you to lose control.
Electrical Safety
4. 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 elec-

trician to install a polarized outlet. Do not
change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power
supply system.
5. Avoid body contact with grounded sur-
faces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. Do not abuse the cord. Never use the cord
to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace
damaged cords immediately. Damaged
cords increase the risk of electric shock.
8. When operating a power tool outside, use
an outdoor extension cord marked “W-A”
or “W”. These cords are rated for outdoor
use and reduce the risk of electric shock.
Personal Safety
9. Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
10. Dress properly. Do not wear loose cloth-
ing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
11. Avoid accidental starting. Be sure switch
is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools
that have the switch on invites accidents.
12. Remove adjusting keys or wrenches
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool may result in personal injury.
13. Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
14. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions. Ordinary
eye or sun glasses are NOT eye protection.
Tool Use and Care
15. Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead
to loss of control.
16. Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.
17. Do not use tool if switch does not turn it
on or off. Any tool that cannot be controlled
with the switch is dangerous and must be
repaired.
18. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
19. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edges are less likely
to bind and are easier to control.
21. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool ser-
viced before using. Many accidents are
caused by poorly maintained tools.
4
22. Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool, may become hazardous when used
on another tool.
SERVICE
23. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
could result in a risk of injury.
24. When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
USE PROPER EXTENSION CORD: 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. Table 1 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 num-
ber, the heavier the cord.
SPECIFIC SAFETY RULES USB002-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to hammer drill safety
rules. If you use this tool unsafely or incorrectly, you can suffer
serious personal injury.
1. Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a “live”wire will
make exposed metal parts of the tool “live”
and shock the operator.
2. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
3. Hold the tool firmly with both hands.
Always use the side grip.
4. Keep hands away from rotating parts.
5. Do not leave the tool running.
Operate the tool only when hand-held.
6. Do not touch the bit or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.

Selecting the action mode
This tool has an action mode changing knob.
For rotation with hammering, turn the knob so that the
mark is towards the small diamond marking on the tool body.
For rotation only, turn the knob so that the mark is
towards the small diamond marking.
CAUTION:
•Always turn the action mode changing knob all the way
to your desired mode position. If you operate the tool
with the knob positioned halfway between the mode
symbols, the tool may be damaged.
ASSEMBLY CAUTION:
•Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (auxiliary handle)
Screw the side grip on the tool securely.
Installing or removing drill bit
To install the bit, place it in the chuck as far as it will go.

Depth gauge
The depth gauge is convenient for drilling holes of uniform
depth. Loosen the clamp screw and adjust the depth gauge
to the desired depth. After adjusting, tighten the clamp screw.
OPERATION
Hammer drilling operation
CAUTION:
•There is a tremendous and sudden twisting force
exerted on the tool/bit at the time of hole break-through,
when the hole becomes clogged with chips and
particles, or when striking reinforcing rods embedded in
the concrete. Always use the side grip (auxiliary handle)
and firmly hold the tool by both side grip and switch
handle during operations. Failure to do so may result in
the loss of control of the tool and potentially severe
injury.
When drilling in concrete, granite, tile, etc., turn the action
mode changing knob to the position of symbol to use
“rotation with hammering”action.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then pull
the switch trigger. Do not force the tool. Light pressure gives
best results. Keep the tool in position and prevent it from slip-
ping away from the hole.
Do not apply more pressure when the hole becomes clogged
with chips or particles. Instead, run the tool at an idle, then
remove the bit partially from the hole. By repeating this sev-
eral times, the hole will be cleaned out and normal drilling
may be resumed.

Blow-out bulb (optional accessory)
After drilling the hole, use the blow-out bulb to clean the dust
out of the hole.
Drilling operation
CAUTION:
•Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve to
damage the tip of your bit, decrease the tool
performance and shorten the service life of the tool.
•There is a tremendous force exerted on the tool/bit at the
time of hole break through. Hold the tool firmly and exert
care when the bit begins to break through the workpiece.
•A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back out.
However, the tool may back out abruptly if you do not
hold it firmly.
•Always secure small workpieces in a vise or similar hold-
down device.
When drilling in wood, metal or plastic materials, turn the
action mode changing knob to the position of symbol to
use “rotation only”action.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makes drilling easier by pulling the bit into the workpiece.
Drilling in metal
To prevent the bit from slipping when starting a hole, make
an indentation with a center-punch and hammer at the point
to be drilled. Place the point of the bit in the indentation and
start drilling.
Use a cutting lubricant when drilling metals. The exceptions
are iron and brass which should be drilled dry.
