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.

]&//#HD3$/3C#W16#!([614X#[$DXK^

HD3$/3C#W16#!([614X#[$DX

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. ]&//#,*%$/#<K^

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. ]&//#,*%$/#<K^

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. ]&//#,*%$/#<K^

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. ]&//#,*%$/#<K^

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. 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.

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 Bit orientation, pull back on the

Position Ring, rotate the Bit as desired, and allow the

Position Ring to slide back into place. Make sure the

Bit position is locked in place before using the tool.

7. To adjust the Front Handle, loosen the

Handle Knob on its side, rotate it as needed,

and retighten the Handle Knob 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.

Tool will

not start.

1. Cord not connected.

2. No power at outlet.

3. Tool’s thermal reset breaker

tripped (if equipped).

4. Internal damage or wear.

(Carbon brushes or

Trigger, for example.)

1. Check that cord is plugged in.

2. Check power at outlet. If outlet is unpowered,

turn off tool and check circuit breaker. If breaker

is tripped, make sure circuit is right capacity

for tool and circuit has no other loads.

3. Turn off tool and allow to cool.

Press reset button on tool.

4. Have technician service tool.

Tool operates

slowly.

Extension cord too long

or wire size too small.

Eliminate use of extension cord. If an extension

See Extension Cords in GROUNDING section.

Performance

decreases

over time.

1. Bit dull or damaged.

2. Internal lubrication cold.

3. Carbon brushes worn

or damaged.

1. Keep cutting bits sharp. Replace as needed.

2. Allow tool to operate with no load

for 5 minutes before use.

3. Have qualified technician replace brushes.

Excessive

noise or

rattling.

Internal damage or wear.

(Carbon brushes or bearings,

for example.)

Have technician service tool.

Overheating. 1. Forcing tool to work too fast.

2. Bit dull or damaged.

3. Blocked motor housing vents.

4. Motor being strained by long or

small diameter extension cord.

1. Allow tool to work at its own rate.

2. Keep cutting bits sharp. Replace as needed.

3. Wear ANSI-approved safety goggles and

NIOSH-approved dust mask/respirator while

blowing dust out of motor using compressed air.

4. Eliminate use of extension cord. If an extension cord is

needed, use one with the proper diameter for its length

and load. See Extension Cords in GROUNDING section.
