3. 

Disconnect the plug from the power source 

before making any adjustments, changing 

accessories, or storing power tools.

  

Such preventive safety measures reduce the 
risk of starting the power tool accidentally.

4. 

Store idle power tools out of the reach of 

children and do not allow persons unfamiliar 

with the power tool or these instructions 

to operate the power tool.

  Power tools are 

dangerous in the hands of untrained users.

5. 

Maintain power tools.  Check for misalignment 

or binding of moving parts, breakage of parts 

and any other condition that may affect the 

power tool’s operation.  If damaged, have the 

power tool repaired before use.

  Many accidents 

are caused by poorly maintained power tools.

6. 

Keep cutting tools sharp and clean.

  Properly 

maintained cutting tools with sharp cutting edges 

are less likely to bind and are easier to control.

7. 

Use the power tool, accessories and tool bits 

etc. in accordance with these instructions, 

taking into account the working conditions 

and the work to be performed.

  Use of the 

power tool for operations different from those 

intended could result in a hazardous situation.

Service

Have your power tool serviced by a qualified repair 

person using only identical replacement parts. 

  

This will ensure that the safety of the 

power tool is maintained.

Percussion Hammer Safety Warnings

1. 

Wear ear protectors.

  

Exposure to 

noise can cause hearing loss

.

2. 

Use auxiliary handles if supplied with the 

tool.

 

Loss of control can cause personal injury.

3. 

Hold power 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 may 

make exposed metal parts of the tool “live” and 
could give the operator an electric shock.

 

4. 

Keep clear of moving parts.

5. 

Unplug before inspecting, removing or 

installing bit, or performing any service.

6. 

Pull on bit after installation and before use; 

bit may move but MUST NOT slide out.

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.

12. 

When using a handheld power tool, 

maintain a firm grip on the tool with 

both hands to resist starting torque. 

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.
