4.  Let bit cool before touching, changing 

or adjusting it.  Bits heat up dramatically 
while in use, and can burn you.

drill torque can cause injury or break bit.

6.  Maintain labels and nameplates on the tool.   

These carry important safety information.   
If unreadable or missing, contact 
Harbor Freight Tools for a replacement.

sawing, grinding, drilling, and other construction 
activities, contains chemicals known to the State

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.
