7. Wear steel-toed boots during use.
8. Do not operate this tool if you have back, neck,
or wrist injuries, or other conditions that will
be aggravated by the severe jerking forces
that this tool exerts upon the operator.
9. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
10. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
11. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.

13. Do not leave the tool unattended when it is plugged
into an electrical outlet. Turn off the tool, and
unplug it from its electrical outlet before leaving.
14. This product is not a toy.
Keep it out of reach of children.
15. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
In addition, people with pacemakers should:
• Avoid operating alone.
• Properly maintain and inspect to avoid
electrical shock.
• Properly ground power cord. Ground Fault Circuit
Interrupter (GFCI) should also be implemented
– it prevents sustained electrical shock.
16. The warnings, precautions, and instructions
discussed in this instruction manual cannot cover all
possible conditions and situations that may occur.
It must be understood by the operator that
common sense and caution are factors
which cannot be built into this product,
but must be supplied by the operator.

1. Tools marked with “Grounding Required” have
a three wire cord and three prong grounding
plug. The plug must be connected to a properly
grounded outlet. If the tool should electrically
malfunction or break down, grounding provides
a low resistance path to carry electricity away
from the user, reducing the risk of electric
shock. ]?**%aKS(&83%S7'3%,89%R'$7*$1^
2. The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire
in the cord must be the only wire connected
to the tool’s grounding system and must
never be attached to an electrically “live”
terminal. ]?**%aKS(&83%S7'3%,89%R'$7*$1^
3. The tool must be plugged into an appropriate outlet,
properly installed and grounded in accordance
with all codes and ordinances. The plug and outlet

require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with
the applicable standards of Underwriters

Association, and the National Electrical Code.

1. Grounded tools require a three wire extension cord.
Double Insulated tools can use either
a two or three wire extension cord.
2. As the distance from the supply outlet increases,
you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss of
power and possible tool damage. ]?**%A,+7*%@1^
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord. ]?**%A,+7*%@1^
4. When using more than one extension cord
to make up the total length, make sure
each cord contains at least the minimum
wire size required. ]?**%A,+7*%@1^
5. If you are using one extension cord for more
than one tool, add the nameplate%amperes
and use the sum to determine the required
minimum cord size. ]?**%A,+7*%@1^
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

1. Pull the Chuck back to open. ERA6- If the Chuck
is difficult to open, lightly tap it with a hammer.
2. Grease chisel’s shank.
E&$*- The chisel can be inserted at
different angles for various applications.
3. Insert the shank portion of the chisel into Chuck
as far as it will go. Release the Chuck.
4. Pull chisel to verify it is secure.
5. The Side Handle can swing around to either
side of the tool. To adjust its position, turn the
Function Knob counterclockwise and slide
the Handle to the desired position. Turn the
Knob clockwise to lock Handle in place.

1. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
3. Secure loose work pieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be objects, such as utility lines,
nearby that will present a hazard while working.

1. Make sure that the Switch is in the off-position,

prevent damage if they are excessively worn.
5. U@;ECEVk%Once activated, do not press, bear down
or thrust forcibly against the work surface. Hold the
Demolition Hammer with just enough pressure so
that the tool’s own weight supplies the needed force.
ERA6- If the Demolition Hammer has not been
used for a long period of time or is being used
in low temperatures, keep the tool running
for about five minutes to allow for warm-up.
Make sure the Switch properly actuates when
pressed ON and that the tool turns OFF.
6. When work is complete, press the
Switch to the OFF position.
7. To prevent accidents, turn off the tool and
disconnect its power supply after use. Clean, then
store the tool indoors out of children’s reach.
