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.
Vibration Safety
This tool vibrates during use. Repeated or long-term
exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups
to ensure medical problems are not being caused
or worsened from use. Pregnant women or
people who have impaired blood circulation to
the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

Double Insulated Tools: Tools with
Two Prong Plugs
1. Tools marked “Double Insulated” do not
require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with
the applicable standards of Underwriters
Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the following illustration.
]&//#IE3$/3D#X16#"(\614Y#\$EYL^
IE3$/3D#X16#"(\614Y#\$EY
Extension Cords
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. ]&//#,*%$/#=L^
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord. ]&//#,*%$/#=L^
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. ]&//#,*%$/#=L^
5. If you are using one extension cord for more
than one tool, add the nameplate#amperes
and use the sum to determine the required
minimum cord size. ]&//#,*%$/#=L^
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.

4. Release the Chuck Ring. If not, adjust the Bit
until the Chuck Ring slides back into place.
5. Physically check that the Bit is secure before
operating. The Bit will have some play, but
should not come out when pulled.
6. To adjust the Front Handle, twist it to loosen it,
rotate it as needed, and retighten it securely.
Workpiece and Work Area Set Up
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.
If working in the ground or on a concrete slab
on the earth, call local utility company to
ensure that area is clear of utility lines.
5. Protect power cord from crushing, abrasion,
and scraping by broken rock or concrete.
6. Keep power cord away from moving machines.
