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 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.

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 electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation
eliminates the need for the three wire
grounded power cord and grounded power
supply system.
5. Avoid body contact with grounded surfaces 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 clothing 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 serviced before using. Many accidents are
caused by poorly maintained tools.
22. Use only accessories that are recommended 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 maintenance 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 number, the heavier the cord.

Not Recommended

USB009-2

DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to hammer 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. Wear ear protectors when using the tool
for extended periods. Prolonged exposure
to high intensity noise can cause hearing
loss.
3. Wear a hard hat (safety helmet), safety
glasses and/or face shield. Ordinary eye
or sun glasses are NOT safety glasses. It

is also highly recommended that you wear
a dust mask and thickly padded gloves.
4. Be sure the bit is secured in place before
operation.
5. Under normal operation, the tool is
designed to produce vibration. The
screws can come loose easily, causing a
breakdown or accident. Check tightness
of screws carefully before operation.
6. In cold weather or when the tool has not
been used for a long time, let the tool
warm up for a while by operating it under
no load. This will loosen up the lubrica-

tion. Without proper warm-up, hammering
operation is difficult.
7. Always be sure you have a firm footing.
Be sure no one is below when using the
tool in high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the
tool only when hand-held.

11. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
12. Do not touch the bit or parts close to the
bit immediately after operation; they may
be extremely hot and could burn your
skin.
13. Some material contains chemicals which
may be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material supplier safety data.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
