California Proposition 65
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 and other masonry products, and
 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.

General Pneumatic Tool Safety Warnings
WARNING
 Use the tool with proper air pressure.
If the air pressure is high, the rotation speed and reciprocation frequency become faster, causing damage such
as damage or accelerated wear. Also, unexpected accidents could occur.
 Connect the tool to air piping.
In some factories, other than air piping, there may be other piping such as oxygen, nitrogen, gas, etc. Before
connecting to piping, make sure it is the correct piping.
