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

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.

a two or three wire extension cord.

- Clean the loading end of the Bit to remove any
debris, then lubricate the Bit with grease. 2. Pull the Chuck Ring back and hold it. 3. Insert the Bit while twisting it.
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.
