7. 

Do not use a damaged accessory. Before 

each use inspect the accessory such as 

abrasive wheels for chips and cracks, backing 

pad for cracks, tear or excess wear, wire 

brush for loose or cracked wires. If power 

tool or accessory is dropped, inspect for 

damage or install an undamaged accessory. 

After inspecting and installing an accessory, 

position yourself and bystanders away from 

the plane of the rotating accessory and run 

the power tool at maximum no-load speed 

for one minute. 

Damaged accessories will 

normally break apart during this test time.

8. 

Wear personal protective equipment. Depending 

on application, use face shield, safety goggles 

or safety glasses. As appropriate, wear dust 

mask, hearing protectors, gloves and workshop 

apron capable of stopping small abrasive or 

work piece fragments. The eye protection must 

be capable of stopping flying debris generated 

by various operations.

  The eye protection must 

be capable of stopping flying debris generated by 

various operations.  The dust mask or respirator 

must be capable of filtering out particles generated 

by your operation. Prolonged exposure to high 

intensity noise may cause hearing loss.

9. 

Keep bystanders a safe distance away from work 

area. Anyone entering the work area must wear 

personal protective equipment. 

Fragments of work 

piece or of a broken accessory may fly away and 

cause injury beyond immediate area of operation.

10. 

Hold power tool by insulated gripping surfaces 

only, when performing an operation where 

the accessory may contact hidden wiring 

or its own cord.  

An accessory contacting a 

″live″ wire may make exposed metal parts of 

the power tool ″live″ and shock the operator.

11. 

Position the cord clear of the spinning 

accessory. 

If you lose control, the cord may 

be cut or snagged and your hand or arm may 

be pulled into the spinning accessory.

12. 

Never lay the power tool down until the 

accessory has come to a complete stop. 

The spinning accessory may grab the surface 

and pull the power tool out of your control.

13. 

Do not run the power tool while carrying 

it at your side. Accidental contact with the 

spinning accessory could snag your clothing, 

pulling the accessory into your body.

14. 

Regularly clean the power tool’s air vents. 

The motor’s fan will draw the dust inside 

the housing and excessive accumulation of 

powdered metal may cause electrical hazards.

15. 

Do not operate the power tool near flammable 

materials. Sparks could ignite these materials.

16. 

Do not use accessories that require liquid 

coolants. Using water or other liquid coolants 

may result in electrocution or shock.

17. Maintain labels and nameplates on the tool.  

These carry important safety information.  

If unreadable or missing, contact Harbor 

Freight Tools for a replacement.

18. Avoid unintentional starting.  

Prepare to begin work before turning on the tool.

19. 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.

20. Use clamps (not included) or other practical 

ways to secure and support the workpiece to 

a stable platform.  Holding the work by hand 

or against your body is unstable and may 

lead to loss of control and personal injury.

21. This product is not a toy.  

Keep it out of reach of children.

22. 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. 

• Do not use with power switch locked on. 

• Properly maintain and inspect 

to avoid electrical shock. 

• Any power cord must be properly grounded.  

Ground Fault Circuit Interrupter (GFCI) 

should also be implemented – it prevents 

sustained electrical shock.

23. WARNING: Some dust created by power sanding, 

sawing, grinding, drilling, and other construction 

activities, contains chemicals known [to the State 

of California] to cause cancer, birth defects or 

other reproductive harm.  Some examples of these 

chemicals are: 

• Lead from lead-based paints 

• Crystalline silica from bricks and cement or 

other masonry products 

• Arsenic and chromium from 

chemically treated lumber 

Your risk from these exposures varies, depending 

on how often you do this type of work.  To reduce 

your exposure to these chemicals: work in a well 

ventilated area, and work with approved safety 

equipment, such as those dust masks that are 

specially designed to filter out microscopic particles.  

(California Health & Safety Code § 25249.5, 

et seq.

)

24. WARNING: Handling the cord on this product will 

expose you to lead, a chemical known to the State 

of California to cause cancer, and birth defects or 

other reproductive harm. Wash hands after handling.  

(California Health & Safety Code § 25249.5, 

et seq.
